General Cleaning
1. Clean the sprocket wheel (11b).
2. Using a disposable lube gun, insert the needle
nose into the lubrication hole (11a) and inject
grease until it appears at the outside edge of the
sprocket wheel (11b) (Fig. 45).
3. Make sure that the chain brake is disengaged.
Rotate the saw chain (10) by glove hand.
Repeat the lubrication procedure until the entire
sprocket wheel (11b) has been greased.

Guide bar and saw chain maintenance
Most guide bar problems can be prevented merely by keeping the product well
maintained. Incorrect filing 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 difficult to complete straight cuts. If the guide bar is insufficiently
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 and saw chain in
reversed order from assembly.
2. Check the oiling port (16) 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. 46).

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 (21). If it is worn or
damaged due to strain, have it replaced by an
authorised service centre or a similarly qualified
person.
4. Clear residue from the rails on the guide bar (11)
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 (11) and
saw chain (10) (Fig. 47).
