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

0

 angle from the side 

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.

CUT TING 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.

CUT TING 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 / CUT TING 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 
part should be repaired or replaced immediately. 

OPERATION AND MAINTENANCE

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 
horizontal surface.

•

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

•

You can proceed with maintenance actions only described within 
this instruction manual. Any other action can be carried out only by 
authorized service. 

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 

chain (

14

).

•

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

) 

located on the guide bar tip (

fig. O

).

•

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.
