• Use the flat-head screwdriver (31) to turn the chain-tensioner
screw (21) clockwise until the lower part of the saw chain
(17) slides into the guide rail (16). The saw chain (17) must
lie against the underside of the rail. When the chain brake is
released, you should be able to pull the saw chain (17) over
the guide rail (16) by hand.
NOTE
A new saw chain (17) stretches and must be tightened more
regularly.
• Tighten the two locking nuts (20) with the spark plug wrench
(31).
Sharpening and caring for the saw chain
m WARNING!
Risk of injury!
Always wear protective gloves when handling the saw chain
(17). There is a danger of injury from the sharp cutting teeth!
NOTE
A properly maintained and sharpened saw chain reduces the
amount of bodily effort and level of wear and produces a bet-
ter result.
Clean, maintain and sharpen the saw chain regularly.
Maintenance intervals
The figures given here are based on normal operating conditions. In the event of more difficult conditions, such as strong dust generation and
longer daily working hours, the given intervals are to be reduced correspondingly.

Check the saw chain regularly for cracks and damaged rivets.
A grinder can be attached to the grinder support (18) for a
secure grip during grinding.
Use only special Ø 4.8 mm (3/16") round files for saw chains
for the supplied saw chain.
You will find detailed information on sharpening in a sharpen-
ing set, e.g. an Oregon set.
Alternatively, you can use an electrical saw chain sharpening
device and follow the instructions of the manufacturer.
If you have any doubts about carrying out the work, the saw
chain should be replaced.
If necessary, have the sharpening of the saw chain (17) carried
out by a specialist workshop.
• Required parts (not supplied):
- Ø 4.8 mm (3/16") round file for saw chains
- Flat file

• File using forwards movements only to remove material.
• File at an angle of around 25° at an inclination of 10° to
the guide rail (16).
