FELLING A TREE

Deﬁne the tree fall line. Consider wind, lean of the tree, location of

heavy branches, complexity of work after tree fall and other factors.

• When tidying area around the tree remember to ensure proper

ground grip and escape path to use when the tree falls.

• Predict and tidy up two escape paths at 45

opposite to expected line of the tree fall. There must be no obstacles

on these paths (fig. I).

• Make preliminary notch deep for 1/3 of the trunk diameter at the

side opposite to predicted tree fall line.

• Make a felling cut at the side opposite to the previously made felling

notch, and a little higher than lower surface of the notch (fig. J).

• Insert wedges on time to avoid pinching of the saw chain.

• Fell the tree by driving a wedge rather than cutting through the

whole trunk.

• Falling tree may pull other trees.

• Danger zone radius is 2.5 height of the falling tree (fig. I).

Do not fell trees when:

• Conditions in danger zone cannot be determined due to fog,

rain, snow or darkness.

• Line of tree felling cannot be determined due to wind or wind

blows.

CUTTING A TRUNK LYING ON THE GROUND

• Press the bumper spike (12) against the trunk and make a cut

(fig. K).

• If the cut cannot be completed, although the chain saw has been

moved in its whole range, move the guide bar back to certain

distance from the trunk being cut (with cutting chain operating),

move the saw down, position bumper spike (12) and ﬁnish cutting

by lifting the rear handle (10).

• Always keep good feet and ground grip. Do not stand on the

trunk.

• Watch out for possibility of the trunk rotation.

• Observe manual guidelines related to work safety to avoid the

chain saw kick back.

• Always finish cutting at the side of tensile stress to avoid

pinching the chain in kerf of the trunk being cut.

• Do not sink the cutting chain into the ground under the trunk

when cutting. Negligence may cause immediate damage to the

chain.

• When cutting trunk lying on the slope, the operator should

always be at the slope side above the trunk being cut.

CUTTING A TRUNK LIFTED ABOVE THE GROUND

In case the trunk is supported or placed on stable sawing horse,

depending on the place of operation, make the cut 1/3 of the trunk

diameter deep on the side under compressive stress and ﬁnish cutting

on the opposite side (fig. L and M).

TRIMMING / CUTTING BUSHES AND TREE BRANCHES

Start cutting branches of a felled tree at its base and continue towards

top of the tree (cut small branches with one movement).

First, check which way the branch bends. Next, make preliminary cut

from the inside of the bend and ﬁnish at the opposite side (watch out,

the cut branch may spring back).

When trimming tree branches, always cut downward to enable free fall

of cut branch. However, sometimes undercutting the branch from the

bottom may be helpful.

Be very careful when cutting a branch that may be under stress. Such

branch may spring aside and hit the operator.

Do not cut branches when climbing up the tree. Do not stand on

ladder, platforms, logs or positions that may cause loss of balance

and control over the chain saw. Do not cut above level of your

shoulders. Always hold the chain saw with both hands.

SAFE WORK WITH CHAIN SAW

Never use the chain saw during rain and in moisture. Whenever

the extension cord is damaged, remove its plug from mains socket

immediately. Never use damaged power cord.

All parts should be assembled properly and fulfil requirements

that ensure safe chain saw operation. Any damaged protective

angle from the side

part should be repaired or replaced immediately.

Unplug the power cord from the mains socket before commencing

any activities related to installation, adjustment, repair or

maintenance.

STORAGE

• Always keep the chain saw clean.

• Do not use water or any other liquid for cleaning.

• Clean plastic parts of the casing with brush or soft cloth.

• Clean ventilation holes in motor casing regularly.

• Check condition of carbon brushes of electrical motor periodically.

• When not used, the chain saw should be clean and stored on

• Store the saw in dry place, beyond reach of children.

• You can proceed with maintenance actions only described within

MAINTENANCE OF THE GUIDE BAR AND CHAIN

Check condition of the guide bar and chain every 5 hours of the saw

operation.

• Loosen and unscrew the protection nut (5).

• Remove the guide bar cover (6), disassemble the guide bar (13) and

• Clean oil holes and groove (d) in the guide bar (13) (fig. N).

• Lubricate tip chain wheel of the guide bar (15) through the hole (e)

• Check condition of the chain (14).

CHAIN SHARPENING

Pay attention to cutting tools. The chain should be clean and sharp,

that will ensure eﬃcient and safe operation. Operating the saw with

blunt chain causes quick wear of the chain, guide bar and driving

chain wheel, and breaking the chain in the worst case. That is why it is

important to sharpen the chain on time.

Chain sharpening is a complex operation. Sharpening the chain by

yourself will require skills and use of special tools. It is recommended

to entrust sharpening the chain to qualiﬁed persons.

All faults should be repaired by service workshop authorized by the

manufacturer.
