CAUTION
Wear heavy duty work gloves when handling the bar and chain.
Most guide bar problems can be prevented merely by keeping the chainsaw well
maintained. Insufficient guide bar lubrication and operating the saw with a chain
that is
TOO TIGHT will contribute to rapid bar wear. To help minimize bar wear, the
following guide bar maintenance procedures are recommended.
m
CAUTION
Always wear protective gloves during maintenance operations.
Do not carry out maintenance when the engine is hot.
Turning the chain bar
The bar should be reversed every 8 working hours to ensure uniform wear.
Remove the complete side cover,chain bar and chain by loosening the bar fastening
wheel (14) completely.
Keep the bar groove and lubrication hole clean (Fig. 28).
Check the bar rails frequently for wear and, if necessary, remove the burrs and
square-up the rails using a flat file (Not supplied).
Remount the the chain bar (reversed side), chain and side cover.
m
CAUTION
Never fit a new chain to a worn chain bar.
CHAIN MAINTENANCE
Chain sharpening
Chain sharpening requires special tools to ensure that cutters are sharpened at the
correct angle and depth. For the inexperienced chainsaw user, we recommend that
the saw chain be professionally sharpened by the nearest professional Service Cen-
tre. If you feel comfortable sharpening your own saw chain, special tools are availa-
ble from the professional Service Centre.
Sharpen the chain using protective gloves. After sharpening, the cutting links must
all have the same width and length.
