The felt
Þ
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
ß
ow to the
carburetor.
To remove the suction head for replacement, pull it out through
the tank
Þ
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 DOLMAR 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".
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
