1). Disassemble the guide bar (4) and saw chain (3) in reversed
order from assembly.
2). Check the oiling port (11) 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. 14a).
3). Check the drive sprocket (12). If it is worn or damaged due to
strain, have it replaced by an authorised service centre.
4). 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
guide bar (4) and saw chain (3) (Fig. 14b).
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 ush 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. 14c).
NOTE: The condition of the oil passages can be easily
checked. If the passages are clear, the chain will
automatically give o a spray of oil within seconds of the
product starting. Your product is equipped with an automatic
oiling system.
