Chain Brake; Operating The Chain Saw - GRAPHITE 58G945 Betriebsanleitung

Avoid touching the muffler. Hot muffler may cause severe burns.

CHAIN BRAKE

The saw features automatic brake, which stops the chain in case of recoil during chain saw operation. The brake engages
automatically when force of inertia is applied to a weight located inside the brake casing. The chain brake can also be
switched on manually, when the brake lever (6) is moved towards the guide bar (20). Switching the chain brake stops the
chain movement in 0.12 sec.
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 ( 6) 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 (
snapping.
Ensure the chain brake operates correctly and the chain is sharp. It is very important for keeping potential recoil
at a safe level.
CHECKING BRAKE ENGAGEMENT
During this check the saw engine should be switched off.
● Lift the saw while holding the front handle (
● Let the front handle ( 5) go and allow the guide bar to tilt under its own weight and touch the wooden object (fig. H).
● At the contact with the wooden object, the chain brake should engage (brake lever (
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 (
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
