Maintenance and care
5. Reverse the position of the guide rail in the
vice and repeat the working step on the re-
maining teeth.
6. Check that the limit tooth does not project be-
yond the checking tool, and file off any pro-
jection using a flat file, then round down the
profile.
7. After sharpening, clean away all filings and
dust, then lubricate the saw chain in an oil
bath.
The chain must be renewed if:
■
The length of the teeth is less than 5 mm;
■
Where applicable: The mark on the teeth of
the cutting elements is exceeded;
■
The play on the links at the chain rivets is ex-
cessive.
8.6 Checking the chain lubrication (26)
Never operate the device without sufficient chain
lubrication. Otherwise you reduce the service life
of the device. You should therefore check the
amount of oil in the oil tank and the oil supply
each time before starting work.
1. Start the device.
2. Hold the running chain saw about 15 cm
above a tree stump or a suitable foundation.
A light oil film should form on the tree stump
(26/1) if there is sufficient lubrication.
8.7 Adjusting the chain lubrication (28)
DANGER!
Danger of fatal injury and danger of
extremely severe injury.
Danger of fatal injury and danger of ex-
tremely severe injury when the engine is
switched on.
■
Carry out all work with the engine
switched off.
The oil supply rate can be adjusted with an ad-
justing screw. The adjusting screw is on the bot-
tom of the device (28/1).
Use a small screwdriver to adjust the supply rate:
■
Turn it clockwise to decrease the supply rate
■
Turn it counterclockwise to increase the sup-
ply rate
When working, you should regularly check
whether there is sufficient oil present in the oil
tank.
8.8 Checking a standstill when the saw
chain is running in idle
WARNING!
Danger from moving saw chain
A saw chain moving at idling speed can
cause life-threatening injuries when
working.
■
Never work with the chain saw when
the saw chain is moving at idling
speed.
■
Before every use, check that the
saw chain is at a standstill if the en-
gine is running at idling speed.
1. Start the engine and let it run at idling speed.
2. Check that the saw chain is stationary.
3. If the saw chain is moving, the following er-
rors could be present:
■
Idle speed is too high (see chapter 8.9
"Setting the idling speed on the carburet-
tor", page 52
).
■
The coupling is defective, contaminated
or incorrectly set. Contact an AL-KO ser-
vice centre.
8.9 Setting the idling speed on the
carburettor
The idling speed is specified in the technical data
(see
chapter 13 "Technical data", page 56 ). It is
best adjusted with the aid of a speed counter.
If the idling speed is correctly set, the engine runs
round at idling speed and the saw chain does not
move. Depending on the operating location
(mountain, lowland), the idling setting must be
corrected using the "T" idling speed stop screw.
NOTE
The regulating screws "L", for idle fuel
mixture, and "H", full load mixture, may
only be adjusted by an AL-KO service
station.
The saw chain moves without the throttle
being applied:
The idling speed is too high.
1. Turn the "T" idling stop screw (11/5) anti-
clockwise a little until the saw chain no longer
moves.
The engine continually dies if the throttle is
not applied:
The idling speed is too low.
