English
When switching the chainsaw off, the chain may never
come in contact with stones or metal things!

6. Electronic system

Smooth start
To avoid the current peaks after start of the chainsaw, the device is
equipped by the smooth / slow electronic start.
Safety devices on your electric
chainsaw
1. Chain Brake
The chainsaw is fitted with a mechanical chain brake. Should the saw
swing back as a result of impact onto a solid object, the saw chain's
drive immediately stops, due to the response of the hand guard (4).
A braking action is initiated when the back of the hand on the front han-
dle (2) pushes forward onto the hand guard (4) (position B). You should
always check the functioning of the chain brake before using the
saw!
Attention! When releasing the chain brake, pull the hand
guard (4) backwards in the direction of the handle and fix it
here (position A). The switch (9) may not be activated!
Make sure that before putting the chain saw into operation
the hand guard (4) is fixed in the working position.
2. Runout brake
In accordance with relevant regulations this chainsaw is equipped by
the runout brake. it is connected with the chain brake and brakes the
running chain after the chainsaw was switched off. It is activated after
release of the switch (9). This runout brake eliminates the risk of injury
by the running chain.
3. Chain catcher
This chainsaw is equipped by the chain catcher (17). If the chain is bro-
ken during work, the catcher catches quickly the moving chain end thus
preventing injury of the user's hand.
Instructions for professional work
with the electric chainsawu
1. Tree felling
If two or more persons cut down the tree(s) at the same time, the dis-
tance between the persons should be at least twice the height of the
cut tree. During tree felling other persons may not be endangered, el.
distributing lines affected and material/property damaged. Contact of
the falling thee with el. distribution line must be notified immediately
to the relevant distribution company.
When cutting on a slope, the chainsaw operator shall stay above the
cut tree, because the fallen tree will most probably slide or roll down
the slope.

a) Escape route
A
B
Prior to start cutting, the escape route should be planned and cleared,
if necessary. The escape route should lead obliquely from the expected
falling tree track, as can be seen in the Figure.
Prior to start cutting, it is necessary to consider the natural tree leaning,
position of larger branches and wind direction so that the direction of
tree fall may be established. Impurities, stones, free bark, bolts and wires
have to be removed from the tree at first.
b) Creation of a notch
Cut a notch at the right angle to the tree as deep as 1/3 of tree diame-
ter. To make the notch, the horizontal cut shall be done at first to avoid
jamming (seizing) of the chainsaw or the guide bar when starting the
second oblique cut of the notch.
c) Felling cut
Start the felling cut 50 mm above the horizontal cut of the notch, see
the Figure. Make the felling cut in parallel with the notch and so deep
that the trunk residue may remain preserved as a " suspension". The trunk
residue prevents tree swivelling and its fall in the incorrect direction.
Do not cross-cut the tree residue.
When the felling cut approaches the notch (undercut), the tree should
start to fall. If it appears that the tree will most probably not fall in the
desired direction or will be leaned back and will close the chainsaw, stop
cutting and use wooden, plastic or aluminium wedges for opening the
felling cut and for correct directing the tree.
When the tree starts to fall, take the chainsaw out of the cut, switch it
off and leave the risk zone using the escape route. Pay attention to the
falling branches not to stumble!
