Care and maintenance
Guide bar and saw chain maintenance
Guide bar
Most guide bar problems can be prevented merely by keeping the product well
maintained. Incorrect lling and non-standard cutter and depth gauge settings
are the causes of most guide bar problems, primarily resulting in uneven bar
wear. As the bar wears unevenly, the rails widen, which may cause the chain
to clatter and make it difcult to complete straight cuts. If the guide bar is
insufciently lubricated and the product 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 guide bar (12) and saw chain (11) in reversed order from
assembly.
2. Check the oiling port (6) for clogging and clean if necessary to ensure
proper lubrication of the guide bar and saw chain during operation. Use a
soft wire small enough to insert into the oil discharge hole (Fig. 39).

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 product starting. Your product is
equipped with an automatic oiling system.
3. Check the drive sprocket (10). If it is worn or damaged due to strain, have it
replaced by an authorised service agent or a similarly qualied person.
4. Clear residue from the rails on the guide bar (12) by using a screwdriver,
putty knife, wire brush or other similar tool. This will keep the oil passages
open to provide proper lubrication to the guide bar (12) and saw chain (11)
(Fig. 40).
