clockwise) until you feel resistance.
- Remove the chain (A/3) and guide bar (A/4).
- Clean the interior with a brush, in particular the brake-band
area (A/5).
NOTE:
Make sure that no residue or contaminants remain in the oil
guide groove (A/6) and the chain tightener (A/7).

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.
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 MAKITA service
centre.
