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
0 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.
