Upper side of wood under tensile stress
Place one cut (one third of the diameter of the trunk) from
the bottom up.
Then place a second cut on the same point from top which
cuts through the trunk.
Underside of wood under tensile stress
Place one cut (one third of the diameter of the trunk) from
top to bottom.
Then place a second cut on the same point from bottom
which cuts through the trunk.
Strong trunks and strong tension
Place one cut (one third of the diameter of the trunk) from
buttom up.
Then place a second cut with distance to the first cut from
top which cuts through the trunk.

Advices on how to cut off branches

Step cut
Make the first cut from the bottom up (one third of the
branch diameter).
Then, make the second cut from top to bottom opposite to
the first cut. This cuts the branch through.
To remove the remaining piece from the trunk cut it
through from top to bottom close to the trunk.

Advices for cutting down trees

Such work may only be carried out by instructed
specialists.
 Pay attention to the length of the guide bar. Only those trees
are allowed to be cut which have a trunk diameter which is
smaller than the length of the guide bar.
Safeguard the dangerous zone (D) before cutting.

Make sure that there are no persons or animals in the
fall area. Danger to life!
The minimum distance to the next work place must

be 2.5 tree lengths.
Make sure that the working area around the trunk is

free of risk to stumble and that you have an escape route (F)
which is free of obstacles.
Before cutting the tree down decide on the felling
direction (C). Before chopping the tree decide on the
chopping direction. Consider in this case the balance point
of the treetop, neighbour trees, slope direction, state of
health of the tree and the wind direction. On this side the
kerf is cut in.
 Remove interfering branches, scrub and obstacles from the
working area at the trunk and make sure that you have a
safe standing position.
 Thoroughly clean the trunk foot – sand, stones and other
foreign objects make the saw chain edgeless or may
damage it.
 Consider the state of health of the tree – be careful with
trunks with damages or deadwood (droughty, rotten or dead
wood).
Tree felling technique:
Cut a kerf with the saw of approximately one third of the
tree diameter into the trunk. First of all place the
horizontal cut and then as secondly a cut from top in an
angle of 45°.
Shout the warning "Caution" or "Tree is falling"
before starting the fell cut.
Now saw on the opposite side of the trunk a horizontal
chopping cut. This cut should be placed a bit higher
(appr. 4 cm) than the horizontal cut of the kerf.
By no means cut through the trunk. Appr. 1/10 of the
trunk diameter must remain. If the tree starts falling
ahead of time pull out the chain saw immediately out of
the cut and step back or to the side.
Push a key into the horizontal chopping cut in order to
make the tree falling.
Pay attention, when tree starts falling, to perches or
twigs falling down.

Installing the guide bar and the saw chain

Risk of injury!
Stop the engine and wear protective
gloves whenever working on the guide
bar and on the saw chain!
Place the chain saw on a level surface and release the
chain brake. Press the front hand guard (3) against the
front handle (4).
Remove the cover (13) by removing the retaining nuts
(14).
Turn the chain stretching screw (15) anticlockwisely
until the chain stretching pin (16) is in its end position.
Place the guide bar. The chain stretching pin(16) must
engage in the provided hole in the guide bar.
Put the saw chain over the clutch (17) on the chain
wheel (18)
guiding groove of the guide bar.
Attend to the correct running direction of the chain
links!
When assembling, pay attention that the chain
links
are lying correctly within the guide slot and on the
chain wheel.
Remount the cover (13) and tighten the nuts (14) hand-
tight
