GB-7
• Press with your thumbs the stopping button 15 on
the left side of the rear handle and then the operating
switch 9.
• The stopping button 13 is used for unlocking the
switch-on mechanism and does not need to be
pressed again after the device is switched on.
• To switch off the device, release switch 9.
Attention: The sawing chain will start running at
high speed immediately. When putting the saw
down, make sure that the chain never gets in
touch with stones or metal objects.
Warning!
The prolonged utilisation of a tool will subject the user
to vibration and shocks that could lead to Raynaud‘s
syndrome or Carpal tunnel syndrome.
This condition reduces the ability of the hand to sense
and regulate temperature, causes numbness and a
sensation 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 syndrome.
Observe the following in order to reduce the risk of Ray-
naud‘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 con-
stantly 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.
Safety devices on your chain brake
1. Chain brake
(Fig. 8)
This chain saw is equipped with a mechanical brake for
the chain. In the case of uncontrolled movements, when
the tip of the sax blade gets in contact with wood or a
solid object, the drive of the chain is immediately stopped
by activation of the hand guard 4, the motor will not be
stopped. This brake function is initiated by the back of
your hand on the front handle 2 pushing the hand guard.
The proper function of the saw chain brake shall be
checked before each use of the saw.
CAUTION: No buttons should be pressed when
the chain brake is released (hand protection
pulled back in the direction of the handle and
locked).
Always ensure before starting the chainsaw that the
hand protection 4 is locked in the operating position.
To do this, pull back the hand protection in the direc-
tion of the handle.
2. Rundown brake
In accordance with the latest regulations, this chain saw
is equipped with a mechanical rundown brake. This brake
is connected to the chain brake and stops the running
chain after the chain saw has been switched off.
It is activated by releasing the ON/OFF switch. The
rundown brake avoids injuries through the coasting of
the chain.
3. Chain catch bolt
(Fig. 9)
This chainsaw is fitted with a chain catch bolt (17). If the
chain breaks when the saw is in operation, the chain bolt
will catch the loose chain end and thus prevent injury to
the operator‘s hand.
Optional
4. Overloading protection
(Fig. 10)
Your chain saw is designed with a overload protection
with circuit breaker. If the chain saw is clogged (e.g.
blocking of the cutting blade, blade teeth jammed, over-
load cutting) during cutting operation, the overload circuit
breaker will cut the mains power supply automatically to
protect your chain saw.
NOTE:
The circuit breaker will be activated when
cutting current is over 35-40 A, and it can be reset
manually through press reset button (18) after 30s
cooling completely.
Instructions on working properly with the
chain saw
(Fig. 11 - 17)
a) Felling a Tree
When bucking and felling operations are being performed
by two or more persons, at the same time, the felling op-
eration 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 en-
danger any person, strike any utility line, the utility com-
pany 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 neces-
sary befor cuts are started. The retreat path should ex-
tend back and diagonally to the rear of the expected line
of fall as illustrated in Figure 11.
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, perpendicu-
lar to the direction of fall as illustrated in 12. 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.
c) Felling Back Cut
Make the felling back cut at least 2 inches (50 mm) higher
