Warning:
– Stop engine, allow to cool and engage the chain brake before carrying out maintenance
or adjustments to the machine.
– Note: Do not carry out repairs on the machine if you are not qualified to do so, with the
exemption of the items listed in this maintenance section.
10.1 CARBURETOR ADJUSTMENT (FIG.35)
Warning:
– During this operation the chain will be moving.
Ensure protective equipment is worn and
observe all necessary safety precautions.
– Note: The chain MUST NOT move while the
engine is at idle speed.
– The carburettor on your chain saw has been set
at standard values during manufacture.
Adjustments to these values may be required
occasionally.
– To adjust, start the engine and allow the
machine to idle. If the engine stalls, the idle speed is too low. If the chain moves, the idle
speed is too fast. Using a cross slot screwdriver, turn the adjustment screw
clockwise
to increase engine speed, or anti-clockwise to decrease engine speed.
10.2 BAR MAINTENANCE (FIG.36)
– Periodically clean the chain run groove and oil
passages.
– Lubricate the sprocket wheel with bearing
grease.
– Reverse the guide bar on a regular basis to
ensure uniform bar wear.
– Burring of the guide bar rails is normal. Remove
these burrs as appropriate with a flat file.
– The guide bar should be replaced when the
chain run groove is worn, the bar is damaged or
if excessive burring or heating occurs.
