snapping.
Ensure the chain brake operates correctly and the chain is sharp. It is very important for keeping potential recoil at
a safe level.
In case the brake does not operate efficiently, adjust it or repair in authorized service site.
In case the engine operates at high speed with the chain brake switched on, the saw clutch will overheat. When the
chain brake engages during operation of the engine, release the switch off immediately and stop the chain saw.
4.9. Chain tension adjustment.
Cutting chain tends to lengthen during operation due to higher temperature. Longer chain loosens and may slip off
the guide bar.
Ensure the chain (8) remains in the guiding groove of the guide bar (7).
Check the chain tension again (it should be possible to lift the chain by approximately 3 - 4 mm in the middle of the
guide bar).
Do not over-tension the chain. Adjustment of overly heated chain may lead to excessive tension when cooling down.
4.10. Operating the chain saw.
Before starting any planned task, familiarize yourself with section describing safe rules for chain saw operation. It is
recommended to gain experience by cutting waste wood pieces. It will also allow to find out the chain saw possibilities.
Always observe safety regulations.
Use the chain saw only for cutting wood. Cutting other materials is forbidden.
Intensity of vibrations and recoil change depending on the type of wood being cut.
Do not use the chain saw as a lever to lift, move or split objects. When the chain is pinched in wood, switch off the
engine and drive wooden or plastic wedge into the processed piece to release the chain saw. Start the tool again and
commence cutting carefully.
Do not fix the saw to a stationary work station.
Attaching other devices, which are not allowed by the chain saw manufacturer, to the chain saw drive is forbidden.
It is not necessary to apply big force to the chain saw when using the tool. Apply light pressure only while the chain
saw operates.
When the chain saw is pinched in kerf during cutting, do not remove it forcefully. It may cause loss of control over the
chain saw, operator injury and/or damage to the chain saw.
Release the chain brake before starting to work.
Wait until engine reaches its full speed before starting to cut).
Keep maximum speed for the whole time.
Allow the chain to cut wood. Press down the saw lightly.
Stop pressing the saw at the end of the cut to avoid losing control over the tool.
4.11. Protection against recoil.
Recoil is movement of the guide bar of the chain saw up and/or back, which happens when the part of the chain on
the guide bar tip encounters an obstacle.
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.
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, inappropriate operation, maintenance, improper guide bar or chain replacement may
contribute to increase of risk of body injury in case of 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 in accordingly to information
contained in this manual.
4.12. 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.
