●
At the contact with the wooden object, the chain brake should engage (brake lever (
to the ON position).
Ensure the chain brake operates correctly before starting any task. 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 throttle lever
immediately and keep engine speed at low level.
CHAIN TENSION ADJUSTMENT
Cutting chain tends to lengthen during operation due to higher temperature. Longer chain loosens and
may slip off the guide bar.
●
Loosen the guide bar fixing nuts (
●
Ensure the chain ( 21) remains in the guiding groove of the guide bar (20).
●
Use a screwdriver to turn the chain tension adjustment screw (
appropriately (it should slightly hold the guide bar in horizontal position).
●
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) (fig. I).
●
Tighten firmly the guide bar fixing nuts (
Do not over-tension the chain. Adjustment of overly heated chain may lead to excessive tension
when cooling down.
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 (fig. J). 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 engine operates with the throttle fully opened.
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.
●
Press the throttle lever lock (
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 loosing control over the tool.
●
When the cutting has been finished release the throttle lever (
●
Switch off the engine before putting the chain saw away.
Keeping high speed of the engine when not cutting wood causes unnecessary losses and wear of
parts.
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.
