Engine Warranty Maintenance Statement
Maintenance, repair, or replacement of the emission control devices andsystems on this engine, which are being done at the customers expense, maybe performed by any nonroad engine repair establishment or individual.Warranty repairs must be performed by an authorized John Deere dealer.
NOTE: The carburetor is calibrated by the engine manufacturer and shouldnot require any adjustments.
If engine is operated at altitudes above 1829 m(6,000 ft.), some carburetors may require a special high altitude main jet.See your John Deere dealer.
Possible engine surging will occur at high rpm when the machine is inneutral ("N") and the auger is disengaged. This is a normal condition due tothe emission control system.
If engine is hard to start or runs rough, check the TROUBLESHOOTINGsection of this manual.
After performing the checks in the troubleshooting section and your engineis still not performing correctly, contact your John Deere dealer.
Checking Gearbox Lubricant
Auger gearbox has been lubricated at factory and SHOULD NOT requireadditional lubrication.
If for some reason the lubricant should leak out, or if the auger gearbox hasbeen serviced; check lubricant.
2. Loosen screw (A) on each side of belt cover (B). Remove cover.
M71569a
3. Hold down auger drive lever so idler pulley (C) is engaged. Check beltdeflection. Belt should deflect 13 mm (1/2 in.) (D) with moderate thumbpressure.
4. Adjust belt, if necessary:
M96038
· Loosen nut (E). Move pulley (F) toward belt 3 mm (1/8 in.).
5. Check belt guides (G) adjustment. (See Adjusting Belt Guides in thissection.)
6. Install belt cover.
Adjusting Belt Guides
1. Disconnect spark plug wire.
M60921
2. Loosen screw (A) on each side of cover (B). Remove cover.
3. Hold auger drive control lever down to handle.
M71575a
4. Measure distance between belt guide (C) and belt. Distance should be 3mm (3/32 in.). If it is not, loosen guide mounting bolt (D), adjust guide, andtighten bolt.
NOTE: Two extra shear bolts are in the bag of parts included with yoursnowblower.
1. Stop engine.
M71588
2. Remove broken shear bolt (A), if necessary.
3. To help prevent auger from rusting, lubricate auger shaft at two shear boltpoints and at end of each shaft with a lightweight oil. Turn auger on shaftseveral turns to help distribute oil.
4. Line up holes in auger with hole in auger shaft.
M71579
5. Install new bolt with spacer (B) under bolt head. Fasten bolt with lock nut(C).
Reversing Scraper Blade
When edge of blade is worn, rough, or bent, reverse blade.
Remove two shear bolts (A). To help prevent auger from rusting, lubricateauger shaft at two shear bolt points and at the end of each shaft with alightweight oil. Turn auger on shaft several turns to help distribute oil.
Lubricate Wheel Axle
c CAUTION: Avoid injury! Snowblower may be too heavy foryou. If necessary, have another person help you stand snowblower on end.
NOTE: Do this service when there is only a small amount of fuel in fueltank.
1. Stand snowblower on end of auger housing.
2. Remove both wheels.
M71573
3. Lubricate both axles (A) with John Deere Moly High Temperature EPGrease or an equivalent. (See Grease in this section.)
c CAUTION: Avoid injury! Handle fuel with care, it is highlyflammable:
· DO NOT refuel machine while you smoke, when machine is near an openflame or sparks, or when engine is running. STOP engine.
· Fill fuel tank outdoors.
· Prevent fires: clean oil, grease and dirt from machine. Clean up spilledfuel immediately.
· Do not store machine with fuel in tank in a building where fumes mayreach an open flame or spark.
· To prevent fire and explosion caused by static electric discharge, whileyou fill tank, use a non-metal fuel container. If you use a funnel, MAKESURE it is PLASTIC. Avoid using a funnel which has a metal screen orfilter.
· Use only clean approved containers and funnels.
· Store oil and fuel in an area protected from dust, moisture and othercontamination.
IMPORTANT: Avoid damage! Avoid spilling fuel. Fuel can damageplastic and painted surfaces.
DO NOT mix oil with gasoline. Unleaded gasoline with an octane rating of87 or higher is recommended.
Fuel tank capacity is 1.9 L (2 qt.).
· Use only clean, fresh, unleaded regular grade gasoline.
· Remove any trash from top of fuel tank drain area.
· Use summer blended fuel for warm weather operation and winter blendedfuel for cold weather.
· Never use fuel that is stale or has been stored for a long period of time:
· Fill fuel tank at the end of each day's operation. This helps to keepcondensation out of fuel tank.
Oxygenated Fuel
Oxygenates (either ethanol or MTBE) are added to the gasoline. If you usethe oxygenated fuel be sure it is unleaded and meets the minimum octanerating requirement.
The following are the EPA approved percentages of fuel oxygenates:
ETHANOL (Ethyl or Grain Alcohol): You may use gasoline containing upto 10 percent ethanol by volume.
MTBE (Methyl Tertiary Butyl Ether): You may use gasoline containing upto 15 percent MTBE by volume.
Filling Fuel Tank
c CAUTION: Avoid injury! Allow engine to cool before refuelingmachine.
1. STOP engine. If engine is hot let it cool several minutes before you addfuel.
M96036
2. Remove fuel tank cap (A).
NOTE: Fuel tank capacity is 1.9 L (2 qt.). Do Not over-fill. Allow space in fuel tank forexpansion.
3. Fill fuel tank to 13 mm (1/2 in.) below bottom of filler neck to allowroom for gasoline to expand.
