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 brakeband 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.

Replacing the suction head

1

B

The felt filter (B/1) of the suction head can become clogged. It is recommended to replace the suction head once every three months in order to ensure unimpeded fuel flow to the car- buretor. To remove the suction head 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 saw chain

CAUTION:

Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)!

Check the sprocket (C/1) before mounting a new chain.

The sprocket is located underneath the clutch drum (C/2).

CAUTION:

Worn out sprockets (D) may damage the new chain and must therefore 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.
