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
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).
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
companies 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.

Maintenance

In order to avoid possible injuries wear gloves.
To guarantee a long and reliable usage of the chain saws carry
out the following maintenance works regularly.
Check the chain saw for obvious defects such as
 loose, hung out or damaged saw chain
 loose fastenings
 worn or damaged components
Check the chain saw after each application for
 wear, especially chain, guide bar and chain wheel.
 correctly assembled and faultless covers and protective
devices.
Necessary repair works or maintenance works have to be
carried out before the usage of the chain saw.

Sharpening of saw chain

You can only work safely and well with a sharp
and clean saw chain. Damaged or incorrectly
sharpened saw chains increase the risk of
kickbacks.
The saw chain has to be sharpened if
 only wood dust is thrown out instead of shavings
 you have to press the chain saw through the wood during
cutting

Inexperienced users: Have the saw chain sharpened by a
specialist/service workshop.
You can also sharpen your saw chain yourself by using our
electric sharpener KSG 220 (article-no.: 302360).
