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.
Cutting off of perches
For horizontal branches without being top heavy

The branch section falls down in a controlled manner without
tipping over.

Set the first cut from below, approx. one third of the
branch diameter.

The second cut is made on the same level as the first cut
or moved further toward the inside (negative breaking
step).

Remove the remaining branch section.

Additional advices for chopping down trees

Such works shall 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!
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 chop-
ping 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 dam-
age it.
 Consider the state of health of the tree – be careful with
trunks with damages or deadwood (droughty, rotten or dead
wood).
Chopping a tree
 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.

Maintenance and cleaning

Before each maintenance and cleaning work
− switch off device
− wait for stop of chain saw
pull out main plug
−
Further maintenance and cleaning works than described in this
chapter shall only be carried out by the manufacturer or compa-
nies named by the manufacturer.
For maintaining and cleaning, removed security devices must
unconditionally be mounted properly and proved again.
Use only original parts. Other parts can result in unexpected
damages and injuries. The manufacturer is not liable for any
damage or injury resulting from such action.

Maintenance

In order to avoid possible injuries wear gloves.
To guarantee a long and reliable usage of the chain saw carry
out the following maintenance works regularly.
Check the chain saw for
 loose or damaged saw chain
 wear, especially chain, guide bar and chain wheel
 worn or damaged components
 correct assembly and faultless covers and protective devic-
es.
Necessary repair works or maintenance have to be carried out
before using the chain saw.
Saw chain and guide bar

Saw chain and guide bar are exposed to a great extent of
wearing. Replace the saw chain and the guide bar without
any delay if their proper function is no longer ensured.
