Disassemble the guide bar and saw chain in reverse order
from assembly. Check the oiling port (10) 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.
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.
Check the drive sprocket (11). If it is worn or damaged due to
strain, have it replaced by an authorised service agent.
Clear residue from the rails on the guide bar (4) using a
screwdriver, putty knife, wire brush or other similar tool. This
will keep the oil passages open to provide proper lubrication
to the bar (4) and chain (3) (Fig. 32).
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 (Fig. 33).
Turn the guide bar 180° to allow even wear, thereby
extending the life span of the guide bar (4).
Check the saw chain for possible wear and damages. Replace
it with a new one if required. Experienced users can sharpen
a dull saw chain (see section ‘Saw chain sharpening’ below).
Refit the saw chain (3) and the guide bar (4) as described
under ‘Assembly’.
