• Ensure the processed material is firmly fixed.
• Use clamps to fix the material.
• Hold the chain saw with both hands when starting up and
during operation.
• During recoil the chain saw cannot be controlled and the chain
is loosened (fig. L).
• Incorrectly sharpened chain increases risk of recoil.
• Do not cut above level of your shoulders.
Avoid cutting with guide bar tip, it may cause sudden recoil
– to the back and up. Always use complete safety equipment
and appropriate working clothes when operating the chain
saw.
Disassembly
of
protections,
maintenance, improper guide bar or chain replacement may
contribute to increase of risk of body injury in case of a recoil.
Never modify the saw in any way. By using modified chain saw,
the user looses all warranty rights. Warranty voids also when
the chain saw is used inaccordingly to information contained
in this manual.
CUTTING PIECES OF WOOD
When cutting wood follow guidelines for safety of work and do
as follows:
• Ensure the wood piece cannot be moved.
• Use clamps to fix short pieces of material before cutting.
• Cut wood or wood-like materials only.
• Before cutting ensure the chain saw will not come into contact
with stones or nails, as it could cause pulling the saw out and
damage to the chain.
• Avoid situations when working saw might touch wired fence
or ground.
• When cutting branches support the saw as much as possible
and do not cut with the tip of the guide bar.
• Watch out for obstacles such as protruding stumps, roots,
hollows and holes in the ground, as they may be cause of an
accident.
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
from the line opposite to expected line of the tree fall. There
must be no obstacles on these paths (fig. M).
• Make a notch at the side of the fall, one third of the trunk
diameter deep (fig. N).
• Make a felling cut at the side opposite to the previously made
felling notch, and a little higher than lower surface of the
notch.
• 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.
When felling trees observe all safety rules and do as follows:
• When the chain is pinched, switch off the chain saw and
release the chain with a wedge. Wedge should be made of
wood or plastic. Never use steel or cast iron wedge.
• Falling tree may pull other trees.
• Danger zone radius is 2.5 height of the falling tree (fig. M).
• If the operator is inexperienced or amateur it is
recommended to have a training rather than gaining the
experience without supervision.
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

CUTTING THROUGH TRUNKS
• Press the bumper spike (19) against the material and make a
cut (fig. O).
• If the cutting cannot be finished even after the chain saw
range is fully utilized, do as follows:
• Move the guide bar back from the cut material to a certain
distance (with cutting chain still operating) and move the
main handle (12) a little down, support the bumper spike (19)
and finish the cut by lifting the main handle (12) a little.
CUTTING A TRUNK LYING ON THE GROUND
• 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 recoil.
• Always finish cutting at the side opposite to compressive
stress to avoid pinching the chain in kerf.
• Before starting to work check the stress direction in the trunk
that is to be cut, to avoid pinching chain of the saw.
• To eliminate stress, the first cut should be made at the tension
side.
• When cutting a trunk that is lying on the gound, first make a
cut deep 1/3 of the trunk diameter, then turn the trunk over
and finish cutting at the opposite side.
• When cutting a trunk that is lying on the ground, do not allow
to sink the cutting chain into the ground under the trunk.
Negligence may cause immediate damage to the chain.
• When cutting trunk that is lying on the slope, the operator
should always be at the slope side above the trunk.
CUTTING A TRUNK LIFTED ABOVE THE GROUND
In case the log 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 tension and finish cutting
on the opposite side (fig. P and R).
TRIMMING / CUTTING BUSHES AND TREE BRANCHES
• Start cutting branches of a felled tree at its base and continue
towards top of the tree. Do small branches with a single cut.
• First, check which way the branch bends. Then make a cut from
the inside of the bend and finish cutting on the opposite side.
Be careful, the branch being cut 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 (fig. S).
• 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.
OPERATION AND MAINTENANCE
Ensure the engine is switched off and is cold before cleaning,
checking or repairing the chain saw. Disconnect wire from the
ignition plug to prevent accidental start up of the engine.
STORAGE
• Empty the fuel system before deciding to store the tool for
more than one month.
• Drain fuel from the fuel tank, start the engine and allow it to
use all remaining fuel and stop working.
• Use new fuel each season. Never use any cleaning agents on
fuel tank, it may damage the engine.
• Pay special attention to keep the ventilation holes of the
engine casing pervious.
