Maintaining the chain lubrication
• See chapter "Checking and adjusting chain lubrication".
13.6 Maintaining the carburettor settings
• If the saw chain (1) moves at idle or the engine stops by
itself when the throttle is released, a carburettor adjust-
ment must be made.
Note
Have carburettor adjustments (e.g. idle speed) carried out
only by qualified specialists to avoid engine damage.
13.7 Maintaining the guide rail (2)
• Remove any burrs on the edge of the guide bar using a
metal file.
• Clean the groove of the guide rail (2) using a brush or
compressed air (Fig. 21). Replace the guide rail (2) as
soon as the guide nut (28) is worn.
• Turn the guide rail (2) after each use to ensure even wear.
• Check the sprocket (30) at the tip of the guide rail (2) for
smooth running. If necessary, lubricate it with a bearing
oil. Let some bearing oil drip into the lubrication hole (31).

13.8 Checking the chain brake
See chapter 10.5 "Checking the chain brake"
m WARNING
RISK OF KICK-BACK!
A non-functioning chain brake increases the risk of kick-back.
Check the chain brake regularly.
A functioning chain brake is essential for your safety.
13.9 Tensioning and checking the saw chain (1)
See chapter 9.2 "Tensioning and checking the saw chain (1)"
13.10 Sharpening and maintaining the saw
chain (1)
m WARNING
Risk of injury!
Always wear protective gloves when touching the saw chain
(1). Danger of injury due to the sharp cutting teeth!
Note
An optimally maintained and sharpened saw chain (1) re-
duces physical strain, wear and leads to good cutting results.
Clean, maintain and sharpen the saw chain (1) regularly.
Check the saw chain (1) regularly for cracks and damaged
rivets.

A bench grinder can be attached to the bench grinder aid for
a secure hold during grinding.
Only use special round saw chain files with Ø 4.8 mm (3/16")
for the saw chain (1) included in the scope of delivery.
In a sharpening kit you will find detailed information on the
sharpening process.
Alternatively, use an electric chain sharpener and follow the
manufacturer's instructions.
If in doubt about the performance of the work, replace the
saw chain (1).
If necessary, have the saw chain (1) sharpened by a specialist
workshop.
• Accessories required (not included in the scope of deliv-
ery):
- Round saw chain file Ø 4.8 mm (3/16")
- Flat file
- Depth limit gauge
• File only in forward motion to remove material.
• File with a sharpening angle of approx. 25° at an incline
of 10° to the guide rail (2).
• Check the depth limit distance with a depth limit gauge.
• The correct distance of the depth limiter should be 0.6 mm
(0.024").
13.11 Maintenance intervals
For a long service life as well as to prevent damage and to
ensure the full function of the safety devices, the maintenance
tasks described below must be carried out at regular inter-
vals. Guarantee claims will only be accepted if these tasks
have been carried out properly and at regular intervals.
There is a risk of accidents if disregarded!
Users of chainsaws are permitted to carry out only those
