Prior to cutting with the chain saw, you must properly prepare the workplace so to minimize the potential risk of danger situations,
which accompany the work with a chain saw. You should make sure, that in the workplace there will be present only authorized
persons.
In the case of trees cutting, you should designate the danger zones and escape routes. A zone within radius of 180 around the
O
anticipated plane of tree fall and a zone with a radius of 90 in the opposite direction to the anticipated plane of tree fall are treated
0
as hazardous zones. The other zones create escape routes (V). You should remember, that the falling tree can fall over also on
next trees. Therefore, the next workplace may not be closer than 2.5 times the height of cut tree (VI).
From the workplace, you should have good visibility, therefore, use caution when you are cutting trees in the difficult terrain
conditions such as. in the mountains.
You should not start works during precipitation and in the case of high humidity, for example mist.
You should wear protective clothing and personal protective equipment.
Before you start the cutting you should carry out a test of wood cutting in safe conditions, for example, with wood placed on a
sawing jack.
You should avoid cutting the wires, young trees and wooden beams.
Do not stand on the cut wood.
Connecting the power to chain saw
Plug the power cord into an extension cord, and the extension cord to power outlet.
Start the chain saw
Make sure, that the rebound brake is in the rear position.
Remove the cover from the guide and chain.
Grasp the front handle with your left hand, and grab the rear handle with your right hand.
Make sure, that the guide and the chain do not contact with any object and surface.
Press the lock button of switch, which is located on the handle.
Press the switch and hold it in this position. You can release the lock button.
Before you proceed to cutting, you should wait until the engine has reached full speed, and make sure that chain smoothly moves
over the guide. If you hear a suspicious sounds or feel vibrations, you should immediately switch off the chain saw
by releasing the switch.
Switching off the chain saw is carried out by releasing the pressure on the switch.
It is forbidden to turn off the chain saw by starting the rebound brake.
When you stop the chain saw you must disconnect it from mains and perform maintenance.
Work with the chain saw
Persons, who are going to work for the first time with the chain saw should seek advice before starting work on the work and safety
from a qualified operator chain saw. The first works with chain saw should rely on cutting prepared logs placed in a sawing jack.
When working you should observe basic occupational safety rules.. You should also take into account the possibility of the chain
saw rebound towards the operator. The chain saw can bounce in the direction of the operator in the case, when the cutting chain
hits a resistance.
To minimize this risk you should:
Pay attention to the location of the peak of guide when cutting. It is forbidden to cut with the top quarter of the guide (VII).
You should cut only with the chain, which moves across the bottom part of the guide. When you are cutting wood, you can use
the lower bumper tooth as a hook of the axis of chain saw rotation (VIII).
For the cut wood you should apply only the chain saw, which is already running. Do not start the chain saw after the it is applied
to the processed wood.
During work do not raise the chain saw at the height shoulders or above (IX).
Do not stand in the cutting plane. This will reduce the risk of injury when the chain saw rebounds (X)
Always, during working, you should hold the chain saw with both hands.
Make sure, the chain is always sharpened and properly tight.
RECOMMENDATIONS FOR WORKING WITH THE SAW
When cutting you should the comfortable position and ensure full freedom of movement.
When cutting branches and boughs you should not cut them close to the trunk, but at a distance of about 15 cm from the trunk.
You should make two incisions on the depth equal to 1/3 the branch diameter about 8 cm apart. One incision from the bottom, the
second from the top. Then cut a branch right next to the trunk to a depth equal to 1/3 the diameter of the branch. Finish cutting by
cutting the branch next to the trunk from the top. It is forbidden to cut branches by cutting them upwards (XI).
When you cut wood you should prepare place for cutting in the manner described above. In addition, you should prepare a safe
background when you cut trees. During the fall of tree you must stand at a safe distance aside to the plane of the tree fall. When
selecting the way of the tree fall you should consider such factors such as terrain shape, center of tree gravity, the distribution of
the crown of the tree and the wind direction. To properly prepare the tree for its cutting, you should perform an incision in the trunk
to a depth of 1/3 of the trunk diameter, on the side, in which you expect the tree to fall, and then cut another incision at 45 degrees
