Care and maintenance
Sprocket nose
Guide bar and saw chain maintenance
> Clean the sprocket nose (6).
> Using a disposable lube gun, insert the
nose of the needle into the lubrication
hole (Fig. 37, A) and inject grease until
it appears on the outside edge of the
sprocket (6) (Fig. 37).
> Make sure that the chain brake (2)
is deactivated. Rotate the saw chain
(4) by hand. Repeat the lubrication procedure until the entire
sprocket (6) 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 (22) 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: It is not necessary to remove the saw chain (4) to
lubricate the sprocket nose (6). Lubrication can be done on
the job.
