brake lever (7) is moved towards the guide bar (9). Switching the chain brake stops the chain
movement in 0.12 sec.
4.8. Braking check.
Ensure the brake operates correctly before each use of the saw.
Put operating saw on the ground and open the throttle fully for 1 - 2 seconds to allow the
saw engine to operate at its maximum speed.
Push the brake lever (7) forward. The chain should stop immediately.
In case the chain stops slowly or does not stop at all, replace the brake band and clutch
drum before using the chain saw again.
To release the brake, pull the brake lever (7) towards the main handle (3) so you can hear
sound typical of blockade 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.
Loosen the guide bar fixing nut (12).
Ensure the chain (8) remains in the guiding groove of the guide bar (9).
Use a screwdriver to turn the chain tension adjustment screw (8) clockwise, until the chain
is strained 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).
Tighten firmly the guide bar fixing nuts (12).
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.
