MAINTENANCE
Warning: Disconnect the spark plug before performing maintenance
except for carburettor adjustments.
We recommend all service and adjustments not listed in this
manual be performed by an authorised service agent.
1. Check For Damaged or Worn Parts
Contact an authorised service agent for replacement of damaged
or worn parts.
Note: It is normal for a small amount of oil to appear under the
chainsaw after the engine stops. Do not confuse this with a leaking
oil tank.
• ON/OFF Switch - Ensure ON/OFF switch functions properly by
moving the switch to the OFF position. Make sure engine stops,
then restart engine and continue.
• Fuel Tank - Do not use chainsaw if fuel tank shows signs of
damage or leaks.
• Oil Tank - Do not use chainsaw if oil tank shows signs of
damage or leaks.
2. Check For Loose Fasteners & Parts
• Chain Bar Nuts
• Chain
• Muffler
• Cylinder Shield
• Air Filter
• Handle Screws
• Vibration Mounts
• Starter Housing
• Front Hand Guard
3. Check Chain Sharpness
A sharp chain makes wood chips. A dull chain makes a sawdust
powder and cuts slowly.
Chain sharpening is a complicated task and requires special tools.
We recommend that you refer chain sharpening to a professional
chain sharpener.
4. Check Guide Bar (Pic. 35 & 36)
Conditions which require guide bar maintenance:
• Chainsaw cuts to one side or at an angle.
• Chainsaw has to be forced through the cut.
• Inadequate supply of oil to bar and chain.
Check the condition of guide bar each time chain is sharpened. A
worn guide bar will damage the chain and make cutting difficult.
After each use , ensure ON/OFF switch is in the OFF position, then
clean all sawdust from the guide bar and sprocket hole.
To maintain guide bar:
• ON/OFF switch to OFF.
• Loosen and remove chain bar nuts and clutch cover. Remove
bar and chain from chainsaw.
• Clean the oil holes and bar groove after every 2 hours of
operation.
Replace guide bar when the groove is worn, the guide bar is bent
or cracked, or when excess heating or burring of the rails occurs. If
replacement is necessary, use only the guide bar specified for your
chainsaw.
5. Clean Unit
• After each use, allow chainsaw to cool about 1 hour. Clean the
unit and decals using a damp cloth with a mild detergent.
• Wipe off unit with a clean dry cloth.
• NEVER allow water or a mild dish washing solution to enter or
drip onto the chainsaw.
• NEVER use solvents, e.g. Petrol, Toluene, Methylated Spirits etc,
to clean the chainsaw, as these will damage the surface finish
and may cause a fire when chainsaw is next used.
6. Check Chain Brake
See CHAIN BRAKE on page 22.
7. Clean Air Filter
Caution: Do not clean filter in gasoline or other flammable solvent
to avoid creating a fire hazard or producing harmful evaporative
emissions.
Cleaning the air filter:
A dirty air filter decreases the life and performance of the engine
and increases fuel consumption and harmful emissions. Always
clean your air filter after 10 tanks of fuel or 2 hours of operation,
whichever comes first. Clean more frequently in dusty conditions.
A used air filter can never be completely cleaned. It is advisable
to replace your air filter with a new one after every 12 hours of
operation, or annually, whichever comes first
Clean air filter in mild soup and warm water.
Do not use petrol or solvents.
Dry thoroughly before using.
