dealer or an experienced chainsaw user. Do notattempt any task that you feel unsure of!

Safety instructions for operation


• This top handle chainsaw is designed specifically fortree surgery and maintenance in the tree. Due to thespecial compact handle design (closely spacedhandles), there is an increased risk of losing control.For this reason these special chainsaws should beused only for work in a tree by persons who aretrained in special cutting and working techniques andwho are properly secured (lift bucket, ropes, safetyharness). Regular chainsaws (with wider spacedhandles) are recommended for all other cutting workat ground level.

• Working in a tree requires the use of special cuttingand working techniques which must be observed inorder to reduce the increased risk of personal injury.Never work in a tree unless you have receivedspecific, professional training for such work,including training in the use of safety and otherclimbing equipment, such as harnesses, ropes,belts, climbing irons, snap hooks, carabiners,etcetera.

• Never attempt to catch falling sections. Never cut inthe tree when you are only secured with one rope.Always use two secured ropes.

• During critical felling operations, hearing protectorsshould be lifted immediately when the sawing iscompleted so that sounds and warning signals canbe heard.

• Before using this product you must understand theeffects of kickback and how to avoid them. Refer to Kickback information on page 11 for instructions.

• Never use a product that is faulty. Carry out thesafety checks, maintenance and service instructionsdescribed in this manual. Some maintenance andservice measures must be carried out by trained andqualified specialists. Refer to Maintenance on page17 for instructions.

• Never use the product with visible damage to thespark plug cap and ignition cable. A risk of sparkingarises, which can cause a fire.

• Never use the product if you are fatigued, whileunder the influence of alcohol or drugs, medication

4 732 - 016 -

or anything that could affect your vision, alertness,coordination or judgement.

• Do not use the product in bad weather such asdense fog, heavy rain, strong wind, intense cold,etcetera. Working in bad weather is tiring and oftenbrings added risks, such as icy ground,unpredictable felling direction, etcetera.

• Faulty cutting equipment or the wrong combinationof guide bar and saw chain increases the risk ofkickback! Only use the guide bar and saw chaincombinations we recommend, and follow the filinginstructions. Refer to Accessories on page 29 forinstructions.

• Never start a product unless the guide bar, sawchain and all covers are fitted correctly. Refer to Introduction on page 9 for instructions. Without aguide bar and saw chain attached to the product theclutch can come loose and cause serious injury.

• Never start the product indoors. Exhaust fumes canbe dangerous if inhaled.

• Observe your surroundings and make sure that thereis no risk of people or animals coming in contact withor affect your control of the product.

• Lack of concentration can lead to kickback if thekickback zone of the bar accidentally touches abranch, nearby tree or some other object.

• Never use a chainsaw by holding it with one hand. Achainsaw is not safely controlled with one hand; youcan cut yourself. Always have a secure, firm griparound the handles with both hands.

• Always hold the chainsaw firmly with your right handon the top handle and your left hand on the fronthandle. Wrap your fingers and thumbs around thehandles. You should use this grip whether you areright handed or left handed. This grip minimizes the

effect of kickback and lets you keep the chainsawunder control. Do not let go of the handles!

• Never use the chainsaw above shoulder height.

• Do not use the product in a situation where youcannot call for help in case of an accident.

• Sometimes chips get stuck in the clutch covercausing the saw chain to jam. Always stop theengine before cleaning.

• If the saw chain jams in the cut: stop the engine!• Running an engine in a confined or badly ventilated

area can result in death due to carbon monoxidepoisoning.

• The exhaust fumes from the engine are hot and maycontain sparks which can start a fire. Do not start theproduct indoors or near flammable material.

• Use the chain brake as a parking brake when youstart the product and when you move shortdistances. Always carry the product in the fronthandle. This decreases the risk that you or a personnear you get hit by the saw chain.

• Overexposure to vibration can lead to circulatorydamage or nerve damage in people who haveimpaired circulation. Contact your doctor if youexperience symptoms of overexposure to vibration.Such symptoms include numbness, loss of feeling,tingling, pricking, pain, loss of strength, changes inskin colour or condition. These symptoms normallyappear in the fingers, hands or wrists. Thesesymptoms may be increased in cold temperatures.

• It is not possible to cover every conceivable situationyou can face when using a chainsaw. Always

• Number of drive links. The number of drive links isdecided by the type of guide bar.

• Bar groove width, in/mm. The groove width in guidebar must be the same as the chain drive links width.

• Chain oil hole and hole for chain tensioner. Theguide bar must align with product.

• Drive link width, mm/in.

General information about how to sharpen thecuttersDo not use a blunt saw chain. If the saw chain is blunt,you must apply more pressure to push the guide barthrough the wood. If the saw chain is very blunt, therewill be no wood chips but sawdust.

A sharp saw chain eats through the wood and the woodchips becomes long and thick.

The cutting tooth (A) and the depth gauge (B) togethermakes the cutting part of the saw chain, the cutter. The

22 732 - 016 -

difference in height between the two gives the cuttingdepth (depth gauge setting).

A

B

When you sharpen the cutter, think about the following:

• Filing angle.

• Cutting angle.

• File position.

• Round file diameter.

It is not easy to sharpen a saw chain correctly withoutthe correct equipment. Use Husqvarna file gauge. Thiswill help you to keep maximum cutting performance andthe kickback risk at a minimum.

WARNING: The force of the kickbackincreases a lot if you do not follow thesharpening instructions.

Note: Refer to To sharpen the saw chain on page 22 forinformation about sharpening of the saw chain.

To sharpen the cutters1. Use a round file and a file gauge to sharpen the

cutting teeth.

Note: Refer to Accessories on page 29 forinformation about which file and gauge thatHusqvarna recommends for your saw chain.

2. Apply the file gauge correctly on to the cutter. Referto the instruction supplied with the file gauge.

3. Move the file from the inner side of the cutting teethand out. Decrease the pressure on the pull stroke.

4. Remove material from one side of all the cuttingteeth.

5. Turn the product around and remove material on theother side.

6. Make sure that all cutting teeth are the same length.

General information about how to adjust thedepth gauge settingThe depth gauge setting (C) decreases when yousharpen the cutting tooth (A). To keep maximum cuttingperformance you must remove filing material from thedepth gauge (B) to receive the recommended depthgauge setting. See Accessories on page 29 forinstructions about how to receive the correct depthgauge setting for your saw chain.
