the gasier yourself!
Breaking in a new saw chain (1)
A new chain and bar will need chain readjustment af-
ter as few as 5 cuts. This is normal during the break-
ing period, and the interval between future adjust-
ments will begin to lengthen quickly.
Sharpening the saw chain
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!
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
with the screwdriver from the assembly tool (23) and
remove the protective sleeve. Afterwards mount the
new protective sleeve.

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).
The chain needs sharpening when:
• The sawdust produced when sawing damp wood
looks like wood our.
• The chain penetrates the wood only under great
pressure.
• The cutting edge is visibly damaged.
• The saw is pulled to the left or right when sawing.
This is caused by uneven sharpening of the chain.
Important: Sharpen frequently, but without re-
moving too much metal!
Generally, 2 or 3 strokes of the le will be enough.
Have the chain resharpened at a service center when
you have already sharpened it yourself several times.
