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 wind blows.
4.14. Cutting through trunks.
Press the bumper spike (9) against the material and make a cut.
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 (4) a little down, support the bumper spike (9) and finish
the cut by lifting the main handle (4) a little.
4.15. 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 ground, 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.
4.16. 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.
4.17. Trimming and 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.
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.
5. 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.
5.1. 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.
