10) Put it together with the spring washer and cover
,and tighten locking nut with the socket wrench
clockwise .
NOTE: The saw chain
has not yet been tensioned. Tension
the chain as described under “Saw chain tensioning”.
After operating the product for approx. 30min, adjust the
chain.
g. Guide bar
Most guide bar problems can be prevented merely by
keeping the product well maintained. Incorrect filling 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 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.
3)
Check the drive sprocket. If it is worn or damaged
due to
strain, have it replaced by an authorised service agent.
4)
Clear residue from the rails on the guide bar 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 and saw chain.
5)
Check the guide bar 'rail' for wear: Hold a ruler (straight
edge) against the side of the guide bar and 'cutter side
plates'. If there is a gap between the ruler and guide bar the
guide bar 'rail' is normal. If there is no gap (ruler flush against
the side of the guide bar) the guide bar 'rail' is worn and
needs to be replaced with a new one of the same type.
6)
Turn the guide bar 180° to allow even wear, thereby
extending the life span of the guide bar.
7)
Check the saw chain for possible wear and damages.
Replace it with a new one if required. Experienced user can
sharpen a dull saw chain (see section “Saw chain sharpening”
below).
