Guide bar and saw chain maintenance
Sprocket nose
NOTE:
It is not necessary to remove the saw chain (3) to
lubricate the sprocket nose (5). Lubrication can be done
on the job.
Clean the sprocket nose (5).
>
Using a disposable lube gun,
>
insert the nose of the needle
into the lubrication hole
(Fig. 36, A) and inject grease
until it appears on the outside
edge of the sprocket (5)
(Fig. 36).

Make sure that the chain brake (2) is deactivated. Rotate the
>
saw chain (3) by hand. Repeat the lubrication procedure until
the entire sprocket (5) has been greased.
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.
Disassemble the guide bar and saw chain in reversed order
>
from assembly.
Check the oiling port (20) 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.
