10 ENGLISH
4.
Do not operate the chain saw in the vicinity of
flammable dust or gases, as the motor generates
sparks and presents
a risk of explosion.
5. Work only on firm ground and with a good footing.
Pay particular attention to obstacles (e.g. the
cable) in the working area. Take particular care
where moisture, ice, snow, freshly cut wood or
bark may make surfaces slippery. Do not stand on
ladders or trees when using the saw.
6. Take particular care when working on sloping ground;
rolling trunks and branches pose a potential hazard.
7.
Never cut above shoulder height.
8.
Hold the chain saw with both hands when
switching it on and using it.
Hold the rear han-
dle 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 dan-
gerous 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 direc
-
tion 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 par
-
ticular, 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.
