Never use the chain saw without the
bumper spike, the saw may pull you
forward suddenly. Always engage the
bumper spike securely.
At the end of the cut, the machine is no
longer supported by the cutting
attachment in the cut. The machine's
weight must be borne by the user – risk
of loss of control!
Felling
Felling may only be carried out by
persons who have had special training.
Persons who are not experienced
machine users should carry out neither
felling nor limbing – increased risk of
accidents!
The cordless chain saw is of only limited
suitability for felling and limbing.
If, however, a tree is to be felled and
limbed with a cordless chain saw, it is
imperative to observe the following
instructions.
Comply with national regulations
regarding felling technique.
Only persons who are engaged in felling
may be present in the felling area.
Make certain that no one is endangered
by the falling tree – motor noise can
drown out shouting.
