of approx. 45 degrees. This will
make it easier to replace the saw
chain (5) onto the sprocket (25).
It is normal that the saw chain (5)
is slack. Sagging in the chain is
normal.
4. Pre-tighten the chain (5) by turn-
ing the tensioning plate (24)
clockwise.
5. Position the sprocket chain wheel
covering (15). First place the tab
(26) on the cover into the corre-
sponding notch on the plate (15).
Only lightly tighten the fastening
bolt (14), as you will still have to
tension the saw.
Note that the saw can re-oil.
Please note that the saw re-oils after use
and oil may leak out if it is stored on its
side or on the head. This is a normal
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 lubrication have
a significant impact on the service life of
the chain.
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.

been released, that is, that the
chain brake lever (3) is pulled up
against the front grip (8).
