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 assem-
bled it completely and inspected!
- Remove the sprocket guard (A/1) (See "PUTTING INTO
OPERATION" figs. A and B).
- Turn the chain tightener screw (A/2) to the left (counter-
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).
- 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 MAKITA service
center.
The felt filter (D/1) of the fuel filter can become clogged. It is
recommended to replace the fuel filter once every three months
in order to ensure unimpeded fuel flow to the carburetor.
To remove the fuel filter for replacement, pull it out through the
tank filler neck using a piece of wire bent at one end to
form a hook.
Replacing the fuel filter
Check the sprocket (B/1) before mounting a new chain.
The sprocket is located underneath the clutch drum (B/2).
CAUTION:
Worn out sprockets (C) may damage the new chain and must
therefore be replaced. If the wear marks on the teeth are very
pronounced (about 0,5 mm /0.02” deep), the sprocket should
be replaced.
Do not attempt to replace the sprocket yourself. Sprocket
replacement requires special training and tools and must be
done at a MAKITA service center.

The spark arrester screen should be checked and cleaned
regularly.
- Loosen the 3 screws (E/1) and remove the spark arrester
screen (E/2).
- Reassembly the spark arrester screen and tighten the
screws. The two long screws must be tigthed with a torque
of 6,3 ft. lb.(8,5 Nm).
CAUTION:
Do not use sharp or pointed objects for screen cleaning.
Damaged or misformed screen wires may result.
