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 car-
burettor adjustment must be made.
Note
Have carburettor adjustments (e.g. idle speed) car-
ried out only by qualified specialists to avoid engine
damage.
13.7 Guide rail maintenance (2) (Fig. 21)
• Remove any burrs on the edge of the guide bar us-
ing 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). (Fig. 21)
13.8 Checking the chain brake
See chapter 10.5 "Checking the chain brake"
m WARNING
DANGER 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
Danger of injury!
Always wear protective gloves when touching the
saw chain (1). Danger of injury due to the sharp cut-
ting teeth!
Note
An optimally maintained and sharpened saw chain
(1) reduces physical strain, wear and leads to good
cutting results.
Clean, maintain and sharpen the saw chain (1) reg-
ularly.
Check the saw chain (1) regularly for cracks and dam-
aged 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 fol-
low 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
delivery):
- 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").
