7. Never cut above shoulder height.
8. Hold the chain saw with both hands when
switching it on and using it.
Hold the rear
handle with your right hand and the front handle
with your left. Hold the handles firmly with your
thumbs. The bar and the chain must not be in
contact with any objects when the saw is
switched on.

9. Clean the area to be cut of foreign objects such
as sand, stones, nails, wire, etc. Foreign objects
damage the bar and chain, and can lead to
dangerous kickback.
10. Take particular care when cutting in the vicinity of
wire fences. Do nut cut into the fence, as the saw
may kick back.
11. Do not cut into the ground.
12. Cut pieces of wood singly, not in bunches or
stacks.
13. Avoid using the saw to cut thin branches and
roots, as these can become entangled in the
chain saw. Loss of balance presents a hazard.
14. Use a secure support (trestle) when cutting sawn
timber.
15. Do not use the chain saw to prise off or brush
away pieces of wood and other objects.
16. Guide the chain saw such that no part of your
body is within the extended path of the saw chain
(see figure).

17. When moving around between sawing operations,
apply the chain brake in order to prevent the
chain from being operated unintentionally. Hold
the chain saw by the front handle when carrying it,
and do not keep your finger on the switch.
18. Withdraw the mains plug when taking breaks or
leaving the chain saw unattended. Leave the
chain saw where it cannot present a hazard.
Kickback
1. Hazardous kickback may arise during work with
the chain saw. Kickback arises when the tip of the
bar (in particular the upper quarter) comes into
contact with wood or another solid object. This
causes the chainsaw to be deflected in the
direction of the operator.

2. In order to avoid kickback, observe the following:
•
Never begin the cut with the tip of the bar.
•
Never use the tip of the bar for cutting. Take
particular care when resuming cuts which
have already been started.
•
Start the cut with the chain running.
•
Always sharpen the chain correctly. In particular,
set the depth gauge to the correct height.
•
Never saw through several branches at a time.
•
When limbing, take care to prevent the bar
from coming into contact with other branches.
•
When bucking, keep clear of adjacent trunks.
Always observe the bar tip.
•
Use a trestle.
Safety features
1. Always check that the safety features are in
working order before starting work. Do not use
the chain saw if the safety features are not
working properly.
− Chain brake:
The chain saw is fitted with a chain brake which
brings the saw chain to a standstill within a fraction
of a second. It is activated when the hand guard is
pushed forwards. The saw chain then stops within
0.15 s, and the power supply to the motor is
interrupted.
