5. Notice: As you pushed the switch (4) and the motor is running, it is not necessary to hold the safety switch (3) pushed. The
safety switch (3) is a safety device to prevent an unintentional start up of the unit.
Switching motor off
With releasing the switch (4), the saw motor will stop automatically. Of you wish to restart the motor, the safety switch (3) and
switch (4) If you want to restart the motor, push the safety switch (3) and switch (4) again.
Chain brake/hand protection cover
The chainsaw is equipped with the chain brake/hand protection cover, which is able to break the running chain in several millisec-
onds and to decrease the risk of backlash. Backlash is a fast movement of the guide strip backward with the end of the strip
touching the article accidental and the strip is closed in a cut.
The hand protection cover (1) will also protect the left hand for case that the hand slips from the handle.
The chain brake is a safety device engaged when pressure is applied on the cover or if the operator strikes the lever with its hand
at backlash. When the chain brake is engaged, the chain movement will stop immediately. The chain brake is to decrease occur-
rence of injuries in result of the backlash. However, it is not able to guarantee full safety – therefore the unit requires careful
handling.
Notice: It is impossible to start the motor until the brake is engaged.
CAUTION: Do not use the chain brake for starting and stopping the saw in normal operation
Warning: If the saw chain and the motor does not stop after braking, have the saw repaired in a closest
shop. Do not use the saw unless the chain brake works correctly.
Notice for work
Saw backlash
With shortening chains, it is necessary to put the tooth stop on the wood to be cut (see Fig.4).
Put the tooth stop firmly before every shortening chain, only than you can cut in wood with the saw. Pull the saw upwards
holding the rear handle and guide it holding the front handle. The tooth stop will serve as a centre of turning. Put the saw on
the front handle pressing on it slightly. Draw it back a little doing that. Put the tooth stop lower and drag the rear handle up-
wards (see Fig 5).
In-feed and longitudinal cuts may be done by especially trained persons (increased risk of backlash, see. Fig. 6).
To make a longitudinal cut, start the saw in as flat angle as possible. Be especially careful as the tooth stop cannot be used.
When the chain is gripped in the material to be cut, the electrical chainsaw may be shot up with the guide strip side directed
towards the operator. Therefore, you should cut with the lower side of the strip where possible. Then, the saw is dragged
from the body to the wood to be cut (see Fug 7 and 8)
At disbranching, the electrical chainsaw should be leaned against the trunk where possible. The tip strip should not be used
for cutting in that case (risk of backlash, see Fig. 6).
Beware of trunks rolling away.
The backlash of the chainsaw may occur when the guide strip tip (the upper quarter in particular) accidentally
touches the wood or other unfailing articles. Then the electrical saw is shot in the direction of operator (risk of
injury)!
Fig. 6
If you do not cut with the tip strip, many injuries may be avoided; the saw may be shot up in a flash. When working with
the saw, wear full protection equipment.
Fasten the material to be cut. Use clamping equipment to hold the material to be cut. It will make operation of the unit
safe using both the hands.
Caution:
For the saw it is necessary to be running immediately before it touches the wood. Switching on (fig. 1): Push the safety switch (3)
and ON/OFF switch (4). The cut wood put on the very lowest tooth of the stop (12). Pull the chainsaw by the main handle (5)
upwards and cut it in the wood. Pull the chainsaw a bit backwards and put the tooth stop (12) lower a bit. Be careful when cutting
the crashed wood. The saw may drag the chips with it.
Switching off: Release the ON/OFF switch. Unplug.
Pull the chainsaw out of wood only when the chain is running. Any operator cutting without a stop may be dragged forward.
Tensioned wood
Fig. 11: There is tension on the upper side of the trunk. Risk: the tree will shoot up! (A= tension,
B= pressure)
Fig. 12: There is tension on the lower side of the trunk. Risk: the tree will shoot down! (A= tension, B= pressure)
Fig. 13: Strong trunks and strong tension. Risk: the tree will shoot with a flash and immense power!
Fig. 14: Lateral tension of the trunk. Risk: The wood will shoot to the side.
Tree felling
Observe all the tree felling safety regulations and proceed as follows:
Only the trees the diameter of which is smaller than the guide strip length may be felled with the chain saw! Never attempt
loosening the closed saw with the motor running. The closed saw should be loosened by a wooden wedge.
Caution:
Dangerous zone: falling trees may carry other falling trees away. Therefore, the dangerous zone should be considered the
double length of the tree (Fig. 15)
Caution:
Before cutting, a good escape way should be planned (A) and made free. The escape way should direct backwards, in the
opposite direction from the falling (B) (Fig. 16).
Caution:
Before making the final cut, make sure that no viewers, animals or obstructions are in the direction of the tree fall.
