Cleaning the inside of the sprocket guard

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 (1) (see PUTTING INTO OPERA-

TION for the correct model) and clean out the interior with a

brush.
Remove the chain (2) and guide bar (3).

NOTE:
Make sure there are no residues or foreign matter remaining in

the oil guide groove (4) or on the chain tensioner (5).
To install the guide bar, saw chain, and sprocket guard, see

PUTTING INTO OPERATION for the correct model.

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.
