Adjusting The Chain Tension; Starting Up A New Saw Chain; Maintaining The Chain Bar - Grizzly AKS 2440 Lion Traduction De La Notice D'utilisation Originale

the inexperienced user of chainsaws,
we recommend to have the saw chain
sharpened by a specialist or a specialist
workshop. If you think yourself capable of
sharpening the chain, you can acquire the
special tools in the specialist trade.
1 .Remove the saw chain (re-
fer to the section on operating
the saw). The chain should be
well-tensioned to ensure proper
sharpening.
2. For the sharpening, a round file
with 4.0 mm diameter is neces-
sary.
Other diameters damage the
chain and can lead to danger
during work!
3. Sharpen only from the inside to
the outside. Guide the file from
the inner side of the cutting teeth
to the outer side. Lift the file
when you are withdrawing it.
4. Sharpen first the teeth on one
side. Turn the saw around and
sharpen the teeth of the other
side.
5. The chain is worn and must be
replaced by a new saw chain if
only approx. 4 mm of the cutting
teeth is remaining.
6. After the sharpening, all cutting
elements must now be equal in
length and width.
7. After every third sharpening, the
sharpness depth (depth limita-
tion) must be checked and the
height filed with the aid of a flat
file. The depth limitation should be
set back about 0.65 mm from the
cutting tooth. After the setting
back of depth limitation, round it
off a little at the front.

Adjusting the chain tension

The adjustment of the chain tension is de-
scribed in the chapter: Starting operation,
tensioning chainsaw.
• Switch off the device and remove the
battery from the device
• Check the chain tension regularly and
re-adjust this as often as possible.When
the saw chain is tensioned with 9 N
(approx. 1 kg), the gap between the
saw chain and the guide rail may not
be more than 2 mm.

Starting up a new saw chain

In the case of a new chain, the tensioning
force decreases after some time. Therefore
you must re-tension the chain after the first
5 cuts and at longer intervals after this.
Never attach a new chain to a
worn drive pinion or place onto
a damaged or worn chain bar.
The chain could spring back or
break, potentially leading to se-
rious injury.

Maintaining the chain bar

Use cut-protection gloves when
handling the chain or the chain bar.
The chain bar must be turned round every
10 working hours, in order to guarantee
uniform wear.
