The chain is correctly tensioned if it does
not sag at the rail underside and can be
rotated completely around with the gloved
hand. 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.
10 min
Switch off the device and remove
the battery before carrying out any
maintenance work.
1. Ensure that the chain brake has
been released, that is, that the
chain brake lever (5) is pulled up
against the front grip (4).
2. Unscrew the fastening bolt (11)
(
).
3. To tension the saw chain, turn
the screw (12) for the chain
quick-tensioning system in
clockwise direction
.
To loosen the tension, turn the
screw (12) in
counter-clock-
wise direction
.
4. Tighten up the fastening bolt (11)
again (
).
With a new saw chain, you must
readjust the chain tension after at
least 5 cutting operations.
Chain lubrication
The rail and chain must never be
without oil. If the cordless chainsaw
is used with too little oil, the cut-
ting performance and lifespan of
the saw chain will decrease as the
process due to the necessary ventilation
opening on the upper edge of the tank and
does not constitute a reason for complaint.
As each saw is checked during production
and tested with oil, a small residue may
be in the tank despite draining, which may
slightly dirty the housing with oil in transit.
Please clean the housing with a cloth.
Prior to changing the chain, the nut of the
guide rail must be cleaned of dirt because
dirt deposits available can cause the chain
to break out of the rail. The deposits can
also absorb the chain oil. So the conse-
quence would be that the chain oil would
not or only a small part of it would reach
the underside of the rail and the lubrication
would be reduced.
Tensioning the saw chain
Regularly tightening the saw chain pro-
vides safety for the user and reduces and/
or prevents wear and chain damages.
Before the start of work and in approx. 10
minute intervals, we recommend the user to
examine the chain tension and correct it, if
necessary.
The chain warms up when working with
the saw and thus expands slightly. These
“expansions” can be expected especially
from newer chains.
Do not re-tighten or change the
chain when it is hot because it
shrinks slightly once it has cooled
down. In case of non-observance,
this can lead to damages on the
guide rail or the engine because
now the chain is too taut on the
blade. Chain tension and chain lu-
brication have a significant impact
on the service life of the chain.
