14. When switching on the chain saw, ensure that it is
supported well and hold it firmly. The chain and bar
must be free.
15. Withdraw the plug immediately if the power cable is
damaged or cut.
16. The chain saw may only be connected to socket
outlets with earthing contact and tested electrical
installations. We recommend the use of a residual-
current-operated circuit-breaker. The fuse must have
a value of 16 A and mustn't be used by other con-
sumers while working with the chain saw.
17. The cable must be winded off completely when you
use a cable drum.
18. Ensure that the power cable has no kinks and is not
damaged.
19. Position the cord so it will not be caught on branches
and the like during cutting.
20. The chain saw may only be used in a completely as-
sembled state. No protective devices may be missing.
21. Switch the chain saw off immediately if you notice
any changes in the machine.
22. Always have a first-aid kit fulfilling DIN 13164 at hand
in case of accidents.
23. If the chain saw comes into contact with earth,
stones, nails or other foreign objects, withdraw the
plug immediately and check the chain as well as
the bar.
24. Ensure that no chain oil penetrates into the earth or
sewage. Always place the chain saw on something
that will absorb any oil dripping from the bar or chain.
25. Avoid to use the chain saw in poor weather condi-
tions, especially if there is a risk of a thunderstorm.
C) Warning to the danger of recoil ("kickback")
26. If possible, use a stand.
27. Always keep an eye on the bar tip.
28. Only place a running saw on the object to be cut.
Never start the machine while the chain rests on
something.
29. So called piercing cuts with the bar tip may only be
carried out by trained personnel.
D) Instructions on safe working techniques
30. Working on ladders, scaffoldings or trees is for-
bidden.
31. Ensure that the wood cannot twist while it is being
cut.
32. Watch out for splintering wood. While you are sawing
you may be injured by flying wood chips.
33. Do not use the chain saw to lever or move the wood.
34. Only cut with the lower section of the saw. The saw
will be repulsed towards you if you try and cut with
the upper section of the saw.
35. Ensure that the wood is free of stones, nails or other
foreign objects.
36. We recommend that first-time users are instructed
practically as to the correct use of the chain saw and
the required personal safety equipment by an expe-
rienced operator; the cutting of round wood or logs
should be trained on a log stand or similar rack-type
device first.
37. Keep the running chain saw from touching the
ground or wire fences.
Warning!
The prolonged utilisation of a tool will subject the user to
vibration and shocks that could lead to Raynaud's syndro-
me or Carpal tunnel syndrome.
This condition reduces the ability of the hand to sense
and regulate temperature, causes numbness and a sen-
sation of heat and can lead to damage to the nervous
system and the circulatory system and to necrosis.
Not all factors that lead to Raynaud's syndrome are
known but cold water, smoking and illnesses that impact
the blood vessels and the circulatory system as well as
severe or long-lasting exposure to vibrations are known
to be factors in the development of Raynaud's syndro-
me. Observe the following in order to reduce the risk of
Raynaud's syndrome and Carpal tunnel syndrome:
• Wear gloves and keep your hands warm.
• Make sure the device is well maintained. A tool with
loose components or with damaged or worn-out
dampers will have a disposition towards increased
vibrations.
• Always hold the handle firmly but do not clutch it cons-
tantly with excessive force. Take breaks often.
All of the above precautions cannot exclude the risk of
Raynaud's syndrome or Carpal tunnel syndrome. There-
fore, with long-term or regular use it is advisable to keep
a close watch on the condition of your hands and fingers.
Seek medical attention immediately in the event of any of
the above symptoms appearing.

(Fig. IV)
a) Felling a Tree
When bucking and felling operations are being per-
formed by two or more persons, at the same time, the
felling operation should be separated from the bucking
operation by a distance of at least twice the height of the
tree being felled. Trees should be felled in a manner that
would endanger any person, strike any utility line, the util-
ity company should be notified immediately.
The chain saw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
A retreat path should be planned and cleared as nec-
essary befor cuts are started. The retreat path should
extend back and diagonally to the rear of the expected
line of fall.
Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direc-
tion to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire
from the tree where felling cuts are to be made.
b) Notching Undercut
Make the notch 1/3 the diameter of the tree, perpen-
dicular to the direction of fall. Make the lower horiziontal
notching cut first. This will help to avoid pinching of either
the saw chain or the guide bar when the second notch is
being made.
