GUIDE BAR AND CHAIN MAINTENANCE
If the guide bar is insufficiently lubricated and the chainsaw is operated with a
saw chain which is too tight, this will contribute to rapid bar wear. To help
minimise bar wear, maintenance of the guide bar as well as the saw chain is
recommended.
1. Disassemble the chain bar and saw chain See "Attaching the Chain bar
and chain" on page 11..
2. Check the oiling port for clogging
and clean if necessary.
NOTE: The condition of the oil
passages can be easily
checked. If the passages are
clear, the chain will
automatically give off a
spray of oil within seconds of
the chainsaw starting.
3. Check the drive sprocket. Have it
replaced by an authorised service centre or a similarly qualified person.
4. Clear residue from the rails on the guide bar with a proper tool like a putty
knife.
5. Check the guide bar 'rail' for wear, if the guide bar 'rail' is worn replace it
with a new one of the same type.
6. Check the chain for possible wear and damage. Replace it with a new
one if required.
7. Refit the chain and the guide bar.
BAR TURNING
1. After approximately 5 hours use, the bar should be turned 180 degrees, to
ensure even wear on the top and bottom of the bar.
2. The bar rails should be cleaned every time the bar is turned, or the chain is
removed. Using a suitable implement, clear any debris from the bar rails.
This will keep the oil passages open and provide correct lubrication to the
bar and chain.
