Chainsaw Operator’s Manual
Chain brake
• Thoroughly clean, particularly around brake band and
operating mechanism.
• Frequent operation of the brake throughout the day
will keep the brake’s internal components free from
an accumulation of dirt and saw dust.
• Ensure correct operation.
Saw chain and guide bar
• Remove side cover, clean and inspect.
• Remove saw chain and visually inspect chain and bar
for wear and cracks.
• Clean out groove, working from the nose backwards. Remove any burrs.
• Clean oil holes.
• Sprocket nose:
− clean out debris
− ensure sprocket rotates and check for broken teeth
− grease, if appropriate.
Figure 18: Cleaning and greasing the sprocket nose.
• Reverse the guide (cutter) bar to equalise wear.
• Install chain and sharpen, or fit spare chain. It may be necessary to change or sharpen the chain
several times during the day.
• Tension chain correctly.
Loose screws/nuts
• Check screws/nuts for tightness. Do not over-tighten.
Safety features
• Check all safety devices are operational.
Fill fuel and chain oil tanks
• Filling the tanks at the end of the day will minimise condensation of water in the tanks during
storage.
