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 (1) (See "PUTTING INTO OPERA-
TION" gs. B) and clean the interior with a brush.
Turn the chain tensioning screw (2) to the left (counter-clockwise)
until pin (3) of the chain tensioner is underneath the threaded
pin (4).
Remove the chain (5) and guide bar (6).
NOTE:
Make sure there are no residues or foreign matter remaining in
the oil guide groove (7) or on the chain tensioner (3).
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.
