SERVICE
Cleaning the brake band and sprocket interior
CAUTION: Before doing any work on the guide bar or chain,
always switch off the engine and pull the plug cap off the
spark plug (see "Replacing the spark plug"). Always wear
protective gloves!
CAUTION: Start the chain saw only after having assembled
it completely and inspected!
Remove the sprocket guard (4) (See "PUTTING INTO OP-
ERATION" figs. A and B) and clean the sprocket interior with
a brush.
Turn the chain tightener screw (5) to the left (counterclockwise)
until you feel resistance.
Remove the chain (3) and guide bar (2).
NOTE:
Make sure that no residue or contaminants remain in the oil
guide groove (1) and the chain tightener (6).
For replacing the guide bar, chain, and sprocket see "PUTTING
INTO OPERATION".
NOTE:
The chain brake is a very important safety device and
like any other component subject to normal wear and
tear.
Regular inspection and maintenance are important for
your own safety and must be done by a DOLMAR service
center.
Cleaning the guide bar, lubricating the sprocket
nose
CAUTION: Protective gloves must be worn.
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to lubricate
the return sprocket bearings regularly (once a week). To do this,
first thoroughly clean the 0.08" (2 mm) hole at the tip of the
guide bar, and then press in a small amount of multi-purpose
grease.
Multi-purpose grease and grease guns are available as
accessories.
