Care and maintenance
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 (22). 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. 38).

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. 39).

Turn the guide bar 180° to allow even wear, thereby extending
>
the life span of the guide bar (4). Loosen the screw and remove
the tension disc (23) from the guide bar (Fig. 40). Ensure the
rubber washer (a) is free of wear. Turn the guide bar and fix the
tension disc with the screw. Apply a drop of suitable glue to the
screw to ensure its safe positioning (Fig. 41).
