General Cleaning; Removing The Guide Bar And Chain - Craftsman 151.98835 Manual Del Usuario

GENERAL CLEANING

Clean the product with a slightly damp cloth
and mild soap. Use a brush for areas that are
hard to reach.
In particular clean the air vents after every
use with a cloth and brush.
Remove stubborn dirt with high pressure air
(max. 3 bar).
Check for damaged or worn parts. Replace
damaged or worn parts before further chain
saw use. Only use identical replacement
parts as listed in the Parts List in this manual.
BAR NOSE
Clean the bar nose. Using a disposable lube
gun, insert the applicator into the lubrication
hole and inject grease until it appears at the
outside edge of the bar nose sprocket.
(Fig. 25)
Rotate the saw chain by hand. Repeat the
lubrication procedure until the entire bar nose
sprocket has been greased.
GUIDE BAR AND SAW CHAIN
MAINTENANCE
Most guide bar problems can be prevented
merely by keeping the chainsaw 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 chainsaw is
operated with a chain which is too tight, the
bar will wear rapidly. To help minimize bar
wear, maintenance of the guide bar as well
as the saw chain is recommended.
CARE AND MAINTENANCE
21 ― English
Check the oiling port (see Fig. 4) 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.
