Additional Safety Instructions For Planers
No list of safety guidelines can be com-plete. Every shop environment is different.Always consider safety first, as it applies toyour individual working conditions. Usethis and other machinery with caution andrespect. Failure to do so could result in seri-ous personal injury, damage to equipmentor poor work results.
Like all power tools, there is danger associ-ated with the Model G1021Z 15" Planer. Usethe tool with respect and caution to lessenthe possibility of mechanical damage oroperator injury. If normal safety precau-tions are overlooked or ignored. Seriouspersonal injury may occur.
1. Ensure that the machine sits firmly on thefloor before use. Any “wobbles” must becorrected by shimming or blocking beforeoperation.
2. This machine is not designed to processany other material except wood.
3. Never position fingers or thumbs near theinfeed roller.
4. Long stock should always be fully support-ed by some type of support fixture.
5. Do not operate planer with dull or damagedknives.
6. Ensure that the planer is properly adjustedbefore using.
7. Do not remove excessive amounts ofwood in a single pass.
8. Inspect your stock before planing. Rejectstock with defects and foreign material.
9. Do not attempt to remove jams until poweris disconnected and all moving parts havecome to a complete stop.
10. Provide adequate infeed and outfeedspace for operating the planer.
11. Do not plane wood less than 12" long and1⁄4" thick.
12. Do not plane lumber with loose knots orknots that may become loose during planing.
Operation of this equipment has the poten-tial to propel debris into the air which cancause eye injury. Always wear safety glass-es or goggles when operating equipment.Everyday glasses or reading glasses onlyhave impact resistant lenses, they are notsafety glasses. Be certain the safety glass-es you wear meet the appropriate stan-dards of the American National StandardsInstitute (ANSI).

220V Operation
SECTION 2: CIRCUIT REQUIREMENTS
The G1021Z Planer motor is wired to operate at220V only. A cordset without a 220V plug isincluded with the Model G1021Z. Plugs andreceptacles can be purchased at your local hard-ware store or home center. Contact your localelectrical contractor if uncertain about connectingto a 220V circuit.
When operating at 220V, we recommend using aNEMA-style 6-15 plug and outlet as depicted inFigure 1 . You may also “hard-wire” the planerdirectly to your panel, provided you place a dis-connect switch near the machine. Check the elec-trical codes in your area for specifics on wiringrequirements.
Under normal load, the Model G1021Z drawsabout 12 amps. We recommend a 15-amp circuitor a 20-amp slow-blow fuse. A circuit rated anyhigher will not adequately protect the motor.
Equipment returned to us for service that showsevidence of being over-fused will be repaired orreplaced totally at the customer’s expense,regardless of the present warranty status.
Fusing
We do not recommend the use of extension cordson 220V equipment. It is much better to arrangethe placement of your equipment and theinstalled wiring to eliminate the need for exten-sion cords. Should it be necessary to use anextension make sure the cord is rated HardService (grade S) or better. Refer to the chart inSection 1: Safety Instructions to determine theminimum gauge for the extension cord. Theextension cord must also contain a ground wireand plug pin. Always repair or replace extensioncords when they become worn or damaged.
Extension Cords
Grounding
This equipment must be grounded. Pleaseensure that this machine is continuouslygrounded from the motor to the machine frameand then to a known ground. Verify that anyexisting electrical outlet and circuit you intendto plug into is actually grounded. If it is not, itwill be necessary to run a separate 12 A.W.G.copper grounding wire from the outlet to aknown ground. Under no circumstances shouldthe grounding pin from any three-pronged plugbe removed. Serious personal injury mayoccur.
Figure 1. NEMA 6-15 220V/15A connector.
220V/240V15A
NEMA L6-15
In the event of an electrical short, groundingreduces the risk of electric shock by providing apath of least resistance to disperse electric cur-rent. This tool is equipped with a power cord hav-ing an equipment-grounding conductor. The out-let must be properly installed and grounded inaccordance with all local codes and ordinances.

Clean Up
The unpainted surfaces are coated with a waxyoil to protect them from corrosion during ship-ment. Remove this protective coating with a sol-vent cleaner or citrus-based degreaser. Avoidchlorine-based solvents as they may damagepainted surfaces should they come in contact.Always follow the usage instructions on the prod-uct you choose for clean up.
Follow the safety rules listed below whenworking with solvents.1. Read and follow all directions and
warnings on the solvent label.
2. Work only in a well ventilated area.
3. Do not work near any type of openflame (e.g., pilot lights, keroseneheaters, and so on).
4. DO NOT smoke while working withflammable material.
5. Paper towels from the cleaning processare extremely combustible. Dispose ofwaste towels so they do not create afire hazard.
Site Considerations
FLOOR LOADYour G1021Z Planer represents a large weightload in a small footprint. Most commercial floorsare suitable for the Model G1021Z. Some resi-dential floors may require additional support toaccommodate both machine and operator.
WORKING CLEARANCESWorking clearances can be thought of as the dis-tances between machines and obstacles thatallow safe operation of every machine withoutlimitation. Consider existing and anticipatedmachine needs, size of material to be processedthrough each machine, and space for auxiliarystands and/or work tables. Also consider the rel-ative position of each machine to one another forefficient material handling. Be sure to allow your-self sufficient room to safely run your machines inany foreseeable operation.
LIGHTING AND OUTLETSLighting should be bright enough to eliminateshadow and prevent eye strain. Electrical circuitsshould be dedicated or large enough to handlecombined motor amp loads. Outlets should belocated near each machine so power or exten-sion cords are not obstructing high-traffic areas.Be sure to observe local electrical codes for prop-er installation of new lighting, outlets, or circuits.
Many of the solvents commonly used toclean machinery can be highly flammable,and toxic when inhaled or ingested. Alwayswork in well-ventilated areas far from poten-tial ignition sources when dealing with sol-vents. Use care when disposing of wasterags and towels to be sure they do not cre-ate fire or environmental hazards. Keepchildren and animals safely away whencleaning and assembling this machine.
Make your shop “child safe”. Ensure thatyour workplace is inaccessible to young-sters by closing and locking all entranceswhen you are away. Never allow visitors inyour shop when assembling, adjusting oroperating equipment.

Gauge Block
Before attempting any table adjustments, you willneed to construct a gauge block. See Figure 10 .A larger gauge block diagram is also included atthe end of the manual for your convenience.Precision adjustments later on require accuracywhen milling the gauge block. Do not use com-mon 2x4 material. Use maple or similar type ofhardwood.
Using a magnetic dial indicator is a good alterna-tive to constructing a gauge block. Use the dialindicator whenever the instructions call for use ofthe gauge block and/or feeler gauge. Refer to thecurrent Grizzly catalog for dial indicators.
Table Adjustment
To plane stock perfectly square, it is importantthat the table is parallel to the cutterhead.
TO CHECK TABLE PARALLELISM:
1. Place the gauge block on the table underone end of the cutterhead.
2. Turn the handwheel to raise the table untilthe block barely touches the cutterheadbody. The block should not be touchingthe knives. See Figure 11 .
3. Slide the block toward the opposite side ofthe cutterhead. Use a feeler gauge to mea-sure the width of the gap, if any, betweenthe top of the block and the bottom of thecutterhead. If there is a gap, make a note,reading the distance from the feeler gauge.
4. If the block wedges tightly between thetable and cutterhead when shifting fromone side to the other, repeat steps 1through 3 above, but start from the oppo-site end of the cutterhead.
Figure 10. Guide block specifications.
DO NOT make adjustments while the planeris running. Ensure that the switch is off,power is disconnected and moving partshave stopped before making adjustments.Failure to comply could result in seriousinjury or electrical shock hazard.
Figure 11. Guide block indicates parallelism.
If the gap difference from one side to the other isequal to or less than 0.004", no further adjust-ment is necessary.
-16- G1021Z 15" Planer
Figure 12. Cap screws for column adjustment.
If the gap difference from one side to the other isgreater than 0.004", but less than 0.016", go tostep 5.
If the gap difference from one side to the other isgreater than 0.016", the table raising chain underthe planer base will need to be adjusted. Pleasecall our Customer Service number for chainadjustment instructions.
To adjust for gap differences of less than 0.016":
5. Determine which side of the table must beraised to correct the gap.
6. Locate the two cap screws in the table cast-ing for each of the columns. See Figure 12 .Loosen both sets of cap screws for eachcolumn on the side you wish to adjust.
7. Push down or pull up the table in thedesired direction. Hold the table in positionand retighten the cap screws.
8. Recheck the table to cutterhead parallelismagain. Repeat steps 1 through 7 until thedeviation is less than 0.004".

Notes
Planer knives are dangerously sharp. Useextreme caution when inspecting, removing,sharpening, or replacing knives into the cut-terhead. Substantial risk of injury!

Figure 14. Placing springs into knife slots.
Figure 15. Cover Removed, Jig on cutterhead
The knives of your planer must be periodicallyadjusted and will ultimately need to be removedfor sharpening. Adjustments should be as preciseas possible with tolerances within .002"-.003" toprolong the sharpness of the knife edges.Improperly adjusted knives can cause an imbal-ance condition in the cutterhead and shortenbearing life, as well as produce substandardplaning results.
TO INSPECT THE KNIVES:
1. UNPLUG THE PLANER!
2. Remove the dust port and upper cover andcutterhead guard to expose the top of thecutterhead. See Figure 15.
Knife Inspection
The knives are set at the factory using jackscrews before shipping. Springs are also includedwith your machine, installed beneath the knives.These may be used instead of the jack screwsdepending on your preference. Refer to Figure13 for placement of the jack screws or springs.
Jack Screw
Spring
Figure 13. Typical placement of jack screws orsprings.
If you decide you prefer to use the spring adjust-ment method, you need to remove each knife,remove the jack screws, leave the two springsunder each knife, and replace the knife.
Loosen the gib bolts until the knife is loose in theslot. The gib bolts turn clockwise to loosen andcounterclockwise to tighten (when facing thehead of the bolt). Carefully remove the knife. Backthe jack screws out completely from the threadedhole and remove. If the springs have become dis-lodged in the removal process, be sure to place 1spring in each of the two holes in bottom of theknife slot. The springs do not go into the threadedhole where the jack screws were installed. SeeFigure 14.
When using jack screws, it is not necessary toinstall the springs. However it will not affect theadjustment if both the springs and jack screwsare in place together.
-18- G1021Z 15" Planer
Figure 16. Proper knife setting jig placement.
3. Remove the belt guard. Carefully turn thecutterhead (using the pulley) until the firstknife is top dead center.
4. Using the knife setting gauge, check theknife height. The jig should sit solidly withboth feet on the cutterhead. See Figure 16.If the knife is adjusted properly, the contactpoint at the center of each adjuster shouldjust touch the tip of the knife. If the knifedoes not make contact, or if the knife caus-es the adjuster’s legs to not seat on the cut-terhead, the knives need to be adjusted. Itmay be helpful to mark the side of the knifewith an ink marker to indicate whether it ishigh or low. This will make the actual adjust-ment process easier.
Once you have completed inspection on all threeknives, you will able to determine whether or notthere is a need to adjust the knives in the cutter-head. Proceed to the appropriate section follow-ing depending upon whether you are using thejack screws or the springs.
Knife Sharpening
Knife sharpness is one of the most important fac-tors in getting good results with the planer. Knivescan be made to last a long time if care is taken inchecking the condition of the wood which is putinto the machine. The biggest problem will comefrom wood with nails or other metal embedded.This will nick or chip the knives and can require acomplete regrinding. Another wear factor is sand,grit, or other dirt on the surface of the wood whichthe knives have to cut through. At the speed thecutterhead is rotating, these types of surface con-tamination can have a very abrasive effect.
This planer has knives with a grind angle of 35˚which is a configuration which should suit mostgeneral planing needs. The optimal grind or bevelangle is a compromise between effective cutting(the smaller the angle the better the cuttingaction) and edge life where the larger the anglethe more the edge is supported, thus the longer itwill last.
For the best results it is best to have planer knivessharpened by a professional sharpening servicewhich has the grinding and measurement equip-ment to assure that the knife cutting geometry ismaintained at optimum levels. It is a procedurewhich requires some care and precision, other-wise, a set of blades can be easily ruined. Knivesshould always be ground as a set so they can beproperly matched. Unequal material removal canresult in an unbalanced cutterhead which canaffect not only planing surface quality but ulti-mately the life of the cutterhead bearings.

Knife Setting
When making adjustments, all three knivesmust be adjusted the same. Do not adjustone knife without adjusting the others aswell. Improper knife height adjustment canresult in damage to knives, poor planer per-formance and possible operator injury.
The knives are locked into the cutterhead withwedge-type gibs and gib bolts. Jack screws underthe knives allow fine tuning to help in the settingprocess.
To set the knives:
1. UNPLUG THE PLANER!
2. Remove the upper cover to expose the cut-terhead.
3. Loosen the gib bolts until the knife is loosein the slot. The gib bolts turn clockwise toloosen and counterclockwise to tighten(when facing the head of the bolt). SeeFigure 17 .
ADJUSTMENTS USING JACKSCREWS
Figure 18. Tightening knives in cutterhead.
5. Adjust the screws below each end of theknife until both feet of the gauge rest even-ly on the cutterhead and the knife is justtouching the bottom of the middle foot ofthe gauge. The gauge will set the knives ata uniform protrusion of approximately .070"above the cutterhead. The knife heightshould vary no more than .002"-.003"across the length of the cutterhead.
6. Maintain a constant pressure on the gaugewhile re-tightening the gib bolts.
7. Repeat the same procedure on the remain-ing knives. As mentioned before, the stan-dard knife setting gauge is satisfactory forreasonably accurate knife setting tasks.
4. Place the knife setting jig over the knife onthe cutterhead as shown in Figure 18 . Thefeet should be securely planted on the cut-terhead. Make sure the gauge extensionrod is parallel to the cutterhead to maintainaccuracy.

7. Re-tighten both locknuts
8. Replace the exhaust hood.
Chip Breaker
The chip breaker is located on the top side of theplaner and extends down around the front of thecutterhead. Its function is to prevent tear-out ordeep, unregulated gouging as the knives removematerial. The chip breaker works by breaking thewoodchips as they are being cut by the cutter-head. The chip breaker also deflects and expelsthe woodchips away from the surface of theboard and out of the planer.
TO ADJUST THE CHIPBREAKER:
1. Disconnect the machine from the powersource, remove the dust hood and lowerthe table.
2. Ensure that the knives are properly adjust-ed.
3. Place the gauge block on the table directlyunder the cutterhead. Using a one millime-ter (0.040") feeler gauge between thegauge block and the cutterhead, raise thetable until one of the knives just touches thefeeler gauge. Rotate the cutterhead manu-ally to be sure the knife is at bottom deadcenter.
4. Lock the table by tightening the table lockknobs.
5. Remove the feeler gauge and slide thegauge block under the chip breaker. SeeFigure 21 . The chip breaker should justtouch the top of the gauge block. Slide thegauge block to the opposite end of the chipbreaker and check it in the same manner.

Feed Roller Height
The infeed and outfeed rollers propel the lumberthrough the planer.The rollers also press the lum-ber flat against the planer table.
Set the infeed and outfeed rollers 0.040" belowthe knife edge at bottom dead center.
TO CHECK ROLLER HEIGHT:
1. Disconnect the machine from the powersource.
2. Lower the table so the gauge block will fitunder one side of the infeed roller.
3. Raise the table until the gauge block barelytouches the infeed roller. See Figure 23 .Do not change position of the table.
4. Slide the gauge block over so it is under theedge of one of the knives. Turn the cutter-head until one of the knives is at bottomdead center over the gauge block.
5. Measure the clearance between the top ofthe gauge block and the edge of the knifewith a feeler gauge. Note the measurementindicated on the feeler gauge.

6. Repeat steps 1-5 for the opposite side ofthe roller. Repeat all steps for the outfeedroller.
Feeler gauge measurement should equal 0.040".
TO ADJUST ROLLER HEIGHT:
1. Remove the drive chain cover to access theroller adjustments on the drive chain side ofthe planer. A single socket head cap screwholds the drive chain cover on. Belt sideadjustments are already accessible.
2. Loosen the roller adjustment check nutsand turn the roller height setscrews tochange the height of the roller as needed.See Figure 24 .
3. Check roller height according to the aboveinstructions. Continue turning the setscrewuntil the roller is properly adjusted.
4. When the roller is set in the correct posi-tion, re-tighten the check nuts you loosenedin Step 2 above.
5. Check your settings one last time andrepeat steps 1-4 if necessary.

4. Remove the springs that are in the holesleft by the setscrews. See Figure 26 .
5. Check for any dirt or grit. Clean the springsand setscrews if dirty.
6. Screw the three regular-pressuresetscrews back in until they are flush withthe top of the head casting.
7. Screw the light pressure setscrew until it isapproximately 1⁄4" above the head casting.The feed chain applies additional tension tothe right side of the outfeed roller, so thepressure added by the setscrew need notbe as high.
To be effective, the infeed and outfeed rollersmust put pressure on the workpiece as it feedsthrough the planer. Too little pressure results inslipping boards, too much pressure results injamming.
Experiment with the best pressure settings foryour work situations. Some rough cut lumber willfeed through fine with relatively few problems,while other lumber will have more difficulty.
Adjusting roller pressure does not affect height.
TO ADJUST ROLLER PRESSURE:
1. Disconnect the machine from the powersource.
2. Ensure that knives and feed rollers are setcorrectly.
3. Unscrew the four large pressure setscrewson top of the planer body. See Figure 25 .

Bed Rollers
Figure 27. Inspecting bed roller height.
4. Use a wrench to turn the eccentric shaftswhich adjust roller height. Stop turningwhen the table rollers are at the properheight.
5. Once your roller heights are correct, re-tighten all the setscrews.
6. Check the height of the table rollers. Repeatsteps 1-5 until the bed rollers are properlyset. Spin the bed rollers to ensure freemovement.
The bed rollers ease stock movement through theplaner. The height of the bed rollers will varydepending on the types of wood you will be plan-ing. When planing rough stock, set the rollersslightly high to keep the lumber from draggingalong the bed. However, snipe may be unavoid-able. Smooth lumber should be planed with therollers set just above the plane of the table. Thiswill minimize snipe.
TO ADJUST THE BED ROLLERS:
1. Ensure that power is disconnected and laya high quality straightedge across bothtable rollers. Use a try square to keep thestraightedge perpendicular to the table.
2. Use a feeler gauge to measure the clear-ance between the bottom of the straightedge and the table. Ideal clearance isbetween 0.002" and 0.005". Measure inseveral places. This measurement must beconsistent across the entire table. SeeFigure 27.

Chip Deflector
The chip deflector keeps chips from falling ontothe outfeed roller. It is the orange plastic platelocated under the top cover.
The beveled edge of the chip deflector should beabout 1⁄8" - 1⁄4" from the knife edge. Carefully rotatethe cutterhead to gauge the distance between thechip deflector and the knives. Adjust if necessary.However, if the chip deflector is set too close tothe knives, the rotating cutterhead may pull it inand destroy it.
TO ADJUST THE CHIP DEFLECTOR:
1. Disconnect the machine from the powersource and remove the planer’s uppercover.
2. Loosen the three deflector mounting bolts.See Figure 29 . Make sure the bevelededge of the deflector faces the cutterhead.
3. Move the deflector until its edge is approxi-mately 1⁄8" - 1⁄4" from the tip of the cuttingknives. Push down on the deflector with awooden stick to check if it will touch theknives. Cautiously rotate the cutterhead toensure clearance. Do Not touch the knives- severe cuts may result.
4. Re-tighten the chip deflector mounting boltsand re-mount the upper cover to the planer.

9. Avoid planing wood with a high water content.Wood with more than 20% moisture content orwood exposed to rain or snow, will plane poor-ly and cause excessive wear to the knives andmotor. Excess moisture can also hasten rustand corrosion.
10.Read as much as possible about planing pro-cedures. Alternative publications present morewood specific planing requirements. They willoften share tips on safety and more efficientways to operate your planer.
1. Inspect lumber for defects, warping, cupping,twisting, and for foreign objects (nails, staples,imbedded gravel, etc,). If you have any ques-tion about the quality of your lumber, do notuse it. Remember, wood stacked on a con-crete floor can have small pieces of stone orconcrete pressed into the wood.
2. Use the full width of the planer. Alternatebetween the left, the right and the middlewhen feeding lumber into the planer. Yourknives will remain sharp much longer.
3. Scrape all glue off of joined boards beforeplaning.
4. Plane ONLY natural wood fiber. No wood com-posites, laminates, particle board, plywoods orplastics should be run through the planer.
5. Surface wood with the grain. NEVER feedend-cut or end-grained lumber into your planer.
6. Do not use boards with knots, splits, cross-grain or other obvious blemishes or defects.They can damage the machine and pose thepossibility of operator injury.

Crank the handwheel to raise or lower the tableaccording to the desired workpiece thickness.Make sure the height scale is properly adjusted.
The power feed features two feed rates; 16 FPMand 20 FPM. When running the machine, theoperator can control the feed speed by movingthe feed control knob. Moving the knob toward themachine produces the 20 FPM feed speed, awayfrom the machine produces 16 FPM and a centerposition places the gear box in neutral. SeeFigure 36.
Figure 36. Feed speed adjustment knob.
The Model G1021Z is equipped with a depth lim-iter located on the bottom of the cutterhead cast-ing just under the nameplate. See Figure 37. Thedepth limiter controls maximum depth of cut to1/8".
With the limiting clip installed, you cannot cutmore than 1/8" in a single pass. While cutting thismuch material is possible, it is not recommended.Take it slow and easy.The quality of your work willbe better and your planer will last longer.

Once the assembly is complete and the adjust-ments are done to your satisfaction, you areready to test the machine.
Turn on the power supply at the main panel.Press the START button. Make sure that your fin-ger is poised on the STOP button, just in casethere is a problem. The planer should runsmoothly, with little or no vibration or rubbingnoises. Strange or unnatural noises should beinvestigated and corrected before operating themachine further.
Test Run
DO NOT attempt to investigate or adjust themachine while it is running. Wait until themachine is turned off, unplugged and allworking parts have come to a rest beforeyou do anything!
If noises occur that cannot be found by visualinspection, feel free to contact our service depart-ment for help.
The species of wood, as well as its condition,have a dramatic effect on planing ability. Theharder the wood (as illustrated by its shearstrength), the more difficult it will be to plane.

Wood Characteristics
The species of wood, as well as condition, willaffect planing ability. The harder the wood, themore difficult it will be to plane. We’ve includedbelow, a list of wood characteristics you mayencounter when planing. The following descrip-tions of defects will give you some possibleanswers to problems you may encounter whileplaning different materials. Possible solutions fol-low the descriptions.
Chipped Grain - usually a result of cuttingagainst the grain, or planing wood with knots orexcessive amount of cross grain. Chipped graincan also be caused by dull knives or misalignedchipbreaker. Often, chipped grain can be avoidedby slowing down the feed rate and by taking shal-low cuts. If those options do not work, inspectyour lumber and determine if its grain pattern iscausing the problem. If the wood does not showsubstantial crossgrain, inspect your knives forsharpness and inspect the chipbreaker for properalignment. See the Adjustment Section.
Fuzzy Grain - Usually caused by surfacing lum-ber with too high a moisture content. Sometimesfuzzy grain is a characteristic of some woods,such as basswood. Fuzzy grain can also becaused by dull knives or an incorrect grindingbevel. Check with a moisture meter. If moisture isgreater than 20%, sticker the wood and allow todry. Otherwise, inspect knife condition.
Glossy Surface - Usually caused by dull knivestaking shallow cuts at a slow feed speed. Surfacegloss will usually be accompanied by overheat-ing. Often, lumber will be scorched and eventual-ly, damage to knives will occur. If knives are sharpon inspection, increase feed speed and/or cuttingdepth.
Snipe - Occurs when board ends have morematerial removed than the rest of the board.Usually caused when one or both of the bedrollers are set too high. Can also be caused bythe chipbreaker or pressure bar being set toohigh. However, small amount of snipe isinevitable.
Snipe can be minimized by proper adjustment ofthe planer’s components, but complete removalof snipe is extremely unlikely. More likely, you willbe able to reduce it to a tolerance of .002". Ifsnipe under that level is a problem, consider plan-ing lumber longer than your intended work lengthand cut off the excess after planing is completed.
Uneven Knife Marks - Uneven knife marks canoccur when the chipbreaker is set too high.Inspect cutterhead bearings if re-adjustment ofthe chipbreaker fails to remedy the situation.
Chatter Marks - Usually caused by incorrectchipbreaker and pressure bar setting heights.Chatter marks can also be caused by running anarrow wood piece through the planer at eitherthe right or left end of the cutterhead. Chatter, likeuneven knife marks, will show in the form of a''washboard'' look. Chatter marks are more likelyto be inconsistent in appearance than unevenknife marks.
Wavy Surface - Caused by poor knife heightadjustment, wavy surface appears when oneknife is taking deeper cuts than the rest of theknives. Remedy by re-setting the knives to a tol-erance of ± .003".
Pitch & Glue Build-up - Glue and resin build-upon the rollers and cutterhead will cause over-heating by decreasing cutting sharpness whileincreasing drag in the feed mechanism. Theresult can include scorched lumber as well asuneven knife marks and chatter.
Chip Marks - Occur when chips aren’t properlyexpelled from the cutterhead. The knives catchthe chips and drag them across the lumber beingplaned. Chips tend to be random and non-uni-form (as compared to chipped grain). Can becaused by exhaust blockage or too much roombetween the cutterhead and chip deflector. Usinga dust collection system in combination with theplaner can help reduce chip marks. Inspect thechip deflector and readjust (as described earlierin the text).

SECTION 7: MAINTENANCE
Make a habit of inspecting your planer each timeyou use it. Check for the following conditions andrepair or replace when necessary:
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged V-belts.
5. Any other condition that could hamper thesafe operation of this machine.
General Knives
The inspection and setting of the planer knives iscovered extensively in Section 5: Adjustments.
Table
The table and other non-painted surfaces on theModel G1021Z should be protected against rustand pitting. Wiping the table clean after every useensures that moisture from wood dust isn’tallowed to trap moisture against bare metal sur-faces.
Some woodworkers recommend using automo-tive paste wax on exposed steel and cast iron sur-faces. The wax provides a layer of protection, aswell as reducing friction between lumber and thetable, making cuts faster and smoother. Avoidwaxes that contain silicone or other syntheticingredients. These materials can find their wayinto lumber that’s being worked, and can makestaining and finishing difficult. If you use pastewax, make sure that it’s 100% Carnauba wax.
-34- G1021Z 15" Planer
Lubrication
The Model G1021Z features factory-sealed bear-ings. A sealed bearing requires no lubricationduring its lifetime. Should a bearing fail, yourplaner will probably develop a noticeable rumble,which will increase when the machine is putunder load. If allowed to get worse, overheating ofthe journal containing the bad bearing couldoccur. If the bad bearing is not replaced, it willeventually seize - possibly doing damage to otherparts of the machine. Bearings are standard sizesand can be replaced through Grizzly.
Proper lubrication of other components of theModel G1021Z are essential for long life and trou-ble-free operation. Below is a list of componentsthat require periodic lubrication. Schedules arebased on daily use. Adjust accordingly for yourlevel of use.
Columns/Lead Screws - The four columnsshould be lubricated weekly with light oil.Unfasten dust covers to gain access. The fourlead screws should be lubricated with generalpurpose grease once a month.
Worm Gear - The worn gear should be inspectedmonthly and lubricated when needed. Removethe worm gear box to inspect. See parts diagramfor location.
Chain - The table height adjustment chain shouldbe inspected monthly and lubricated when need-ed. A good quality bicycle chain lubricant workswell for periodic lubrication.
Gear Box - Gear box oil should be drained afterthe first 20 hours of operation. See Figure 40.Replace with 80W-90 gear oil. Inspect levels peri-odically and change yearly. Replace gear oil morefrequently under heavy use. Fill until oil reachesthe top of the filler plug port for correct oil level.
Drive Chain - The drive chain should be inspect-ed and lubricated monthly. Check sprocket, chainand cotter pin during inspection. Use a generalpurpose grease. Some chains will have masterlinks instead of cotter pins.
Feed Rollers - The infeed/outfeed pressuresetscrews double as lubrication ports for therollers. See Figure 41. Add 1-2 drops of lightmachine oil to all ports before each use. Dailylubrication of feed rollers is crucial to the opera-tion of your planer. Lubricate before start-up.Apply a light oil, making sure that the lubricantpenetrates the bearing.

Clean and lubricate the chain sprockets as need-ed. The gearbox oil should be checked before thefirst use. It is full when oil begins dribbling out ofthe fill hole. Oil should be replaced yearly. Use80W-90 gear oil in normal situations. Use 50Wmotor oil for unheated, winter shops. SeeAdjustment Section.
The lead screws and columns should be wiped ofany grease and dust build up once a week. Theyshould be relubricated with light machine oil. SeeFigure 42.
