cord’s cross-section depends on the length of the cord. Follow the instructions below regarding the power cord cross-section:
- 1.0 mm 2 – cord length not greater than 40 m;
- 1.5 mm
2
– cord length not greater than 60 m;
- 2.5 mm
2
– cord length not greater than 100 m.
When preparing for operation and during operation, pay attention to the power cord. Protect the power cord from water, moisture,
oils, heat sources and sharp objects. Lay the cord so that it does not come within the reach of the cutting element. Cutting the
cord may result in electric shock and serious injury or death. Make sure that you do not become entangled in the cord. This can
lead to a fall and serious injury.
Do not overload the power cord, and do not cause any of the cord’s section to become tensioned. Do not pull the cord when
moving the tool. Always disconnect the power cord plug from the socket by pulling by the plug and socket housing, never pull by
the cord.
There is an opening in the housing to route the extension cord loop through, and then attach the loop to the hook. Only then,
connect the plug to the socket of the extension cord (VII). This will minimise the risk of pulling the power cord from the machine
housing, e.g. in the event of a sudden jerk.
Starting the chainsaw (VIII)
Make sure that the kickback brake is in the rear position.
Remove the guard from the guide bar and chain.
Grasp the front handle with your left hand and the back handle with your right hand.
Make sure that the guide bar and chain do not come into contact with any object or surface.
Press the power switch lock button on the handle with your thumb.
Press and hold the power switch in this position. The lock button can be released.
Before cutting, wait until the motor is at full speed and make sure that the chain runs smoothly along the guide bar. If you hear any
suspicious sounds or vibration, turn the chainsaw o ff immediately by releasing the power switch.
The chainsaw is turned o ff by releasing the power switch.
It is forbidden to turn the chainsaw o ff by applying the kickback brake.
Unplug the chainsaw from the mains and proceed with maintenance once the chain has stopped.
Working with the chainsaw
Persons who intend to work with a chainsaw for the fi rst time should seek advice on work and safety from a quali fi ed chainsaw op-
erator before starting work. The fi rst works with the chainsaw should consist of cutting the prepared logs placed on the saw-horse.
During work, observe the basic occupational safety principles. Consider also the possibility of kickback in the operator’s direction.
The chainsaw may kickback in the operator’s direction when the cutting chain encounters resistance.
To reduce this risk:
Pay attention to the placement of the guide bar top when cutting. It is forbidden to cut with the upper quarter of the guide bar top (IX).
Cut only with the chain which moves along the bottom part of the guide bar. When cutting wood, the lower bumper tooth can be
used as a hook for the chainsaw’s axis of rotation (X).
Only apply the started chainsaw to the wood to be cut. Do not start the chainsaw after having applied it to the wood being pro-
cessed.
When working, do not lift the chainsaw to arm height or higher (XI).
Do not stand in the cutting plane. This will reduce the risk of injury in case of kickback (XII).
During work, always hold the power saw with both hands.
Make sure that the chain is always sharp and appropriately tensioned.
TIPS FOR WORKING WITH THE CHAINSAW
Take a comfortable position and ensure full freedom of movement when cutting.
When cutting branches and boughs, do not cut them at the trunk, but at a distance of about 15 cm from the trunk. Make two cuts
to a depth of 1/3 of the branch diameter, approximately 8 cm apart – One cut from below, one from above. Then cut the branch
just at the trunk to a depth equal to 1/3 of the branch diameter. Finish the process by cutting the branch at the trunk from above.
Do not cut the branches by cutting from the bottom (XIII).
When cutting a tree, prepare the felling site in advance as described above. Additionally, prepare a safe substrate for tree felling.
When a tree falls, stand at a safe distance to the plane of the tree fall, on the side. When choosing the path of wood fall, take
into account factors such as terrain topography, tree centre of gravity, tree crown pattern, and wind direction. To properly prepare
the tree for felling, make a cut in the trunk to a depth of 1/3 of the trunk diameter on the side to which the tree is to fall, and then
cut another at an angle of 45 degrees to the fi rst so as to cut a “wedge” in the trunk. On the other side of the trunk, start cutting
perpendicular to the trunk axis, slightly higher (approx. 4 cm) than the cut “wedge” base. Do not cut the trunk. Leave a section
of approximately 1/10 of the trunk diameter. Then insert the wedge for splitting the tree into the cut on the opposite side to the
planned side of the tree fall (XIV).
If the tree already falls during cutting, pull the chainsaw out of the trunk and move away along the prepared escape route to a
safe distance.
