Cleaning the sprocket interior, checking and re-
placing the chain catch sleeve
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: Do not start the saw until it has been
completely assembled and inspected!
Remove the sprocket guard (17) and clean the interi-
or with a brush.
Remove the chain (1) and guide bar (2).
NOTE:
Make sure that no residue or contaminants remain in
the oil guide groove (K) and the chain tightener (D).
For replacing the guide bar, chain, and sprocket see
section 7.
Chain catch sleeve (Fig.20):
Visually inspect the chain catch sleeve (20) for dam-
age and replace if necessary.
Loosen the mounting screw (M) counterclockwise

Cleaning the guide bar, lubricating the sprocket
nose Fig. 21
CAUTION!: Protective gloves must be worn!
Regularly inspect the bearing surfaces of the guide
bar for damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to
lubricate the return sprocket bearings (G) regularly
(once a week). To do this, first thoroughly clean the 2
mm hole at the tip of the guide bar (H), and then press
in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available
in specialty retail trade.
Replacing the saw chain
CAUTION!: Use only chains and guide bars designed
for this saw.
Check the sprocket (E) before mounting a new chain
(1). Fig. 22
CAUTION!: Worn out sprockets may damage the
new chain and must therefore be replaced.
Replacing the clutch drum and sprocket
The replacement of the clutch drum and sprocket
must be performed by a specialist company.
Replacing the fuel filter Fig. 23
The felt filter (N) 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.
