The felt
fi
lter (
D/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
fl
ow to the
carburetor.
To remove the suction head for replacement, pull it out through
the tank
fi
ller 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 (
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.
Do not attempt to replace the sprocket yourself. Sprocket re-
placement requires special training and tools and must be done
at a MAKITA service centre.
Cleaning the brake band and sprocket interior
A
- Remove the sprocket guard (
A/1
) (See "PUTTING INTO

- 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".

chain, always switch off the engine and pull the
