Tool replacement
Start the brushcutter only in accordance with the instructions.
Do not use any other methods for starting the engine!–– Only start the engine, after the entire assembly is done. Operation of the– device is only permitted after all the appropriate accessories are attached!
Before starting make sure that the cutting tool has no contact with hard– objects such as branches, stones etc. as the cutting tool will revolve when
starting.
The engine is to be switched off immediately in case of any engine problems.– Should the cutting tool hit stones or other hard objects, immediately switch off– the engine and inspect the cutting tool.
Inspect the cutting tool at short regular intervals for damage (detection of– hairline cracks by means of tapping-noise test).
If the equipment gets heavy impact or fall, check the condition before– continuing work. Check the fuel system for fuel leakage and the controls
and safety devices for malfunction. If there is any damage or doubt, ask our
authorized service center for the inspection and repair.
Operate the equipment only with the shoulder harness attached which is– to be suitably adjusted before putting the brushcutter into operation. It is
essential to adjust the shoulder harness according to the user size to prevent
fatigue occurring during use. Never hold the cutter with one hand during use.
During operation always hold the brushcutter with both hands.– Always ensure a safe footing.
Operate the equipment in such a manner as to avoid inhalation of the exhaust– gases. Never run the engine in enclosed rooms (risk of gas poisoning).
Carbon monoxide is an odorless gas.
Switch off the engine when resting and when leaving the equipment– unattended, and place it in a safe location to prevent danger to others or
damage to the machine.
Never put the hot brushcutter onto dry grass or onto any combustible– materials.
Always install the approved cutting tool guard onto the equipment before– starting the engine.
Otherwise contact with the cutting tool may cause serious injury.
All protective installations and guards supplied with the machine must be– used during operation.
– Shut off the engine during transport.– When transporting the equipment, always attach the cover to the metal blade.– Ensure safe position of the equipment during car transportation to avoid fuel– leakage.
When transporting, ensure that the fuel tank is completely empty.– When unloading the equipment from the truck, never drop the Engine to the– ground or this may severely damage the fuel tank.
Except in case of emergency, never drop or cast the equipment to the ground– or this may severely damage the equipment.
Remember to lift the entire equipment from the ground when moving the– equipment. Dragging the fuel tank is highly dangerous and will cause damage

Method of operation
Only use in good light and visibility. During the winter season beware of– slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe
footing.
Never cut above waist height.– Never stand on a ladder.– Never climb up into trees to perform cutting operation.– Never work on unstable surfaces.– Remove sand, stones, nails etc. found within the working range.– Foreign particles may damage the cutting tool and can cause dangerous
kick-backs.
Before commencing cutting, the cutting tool must have reached full working– speed.
When using metal blades, swing the tool evenly in half-circle from right to left,– like using a scythe.
If grass or branches get caught between the cutting tool and guard, always
stop the engine before cleaning. Otherwise unintentional blade rotation may
cause serious injury.
Take a rest to prevent loss of control caused by fatigue. We recommend to– take a 10 to 20-minute rest every hour.

grass.
Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs,
underwood, thicket, and the like.
blades. Otherwise serious injury may result.
When using metal blades, avoid “kickback” and always prepare for an– accidental kickback. See the section “Kickback” and “Kickback prevention.”
Kickback (blade thrust)
Kickback (blade thrust) is a sudden reaction to a caught or bound metal– blade. Once it occurs, the equipment is thrown sideway or toward the
operator at great force and it may cause serious injury.
Kickback occurs particularly when applying the blade segment between 12– and 2 o’clock to solids, bushes and trees with 3 cm or larger diameter.
To avoid kickback:– Apply the segment between 8 and 11 o’clock;
Never apply the segment between 12 and 2 o’clock;
Never apply the segment between 11 and 12 o’clock and between 2 and
5 o’clock, unless the operator is well trained and experienced and does it at
his/her own risk;
Never use metal blades close to solids, such as fences, walls, tree trunks
and stones;
Never use metal blades vertically, for such operations as edging and
trimming hedges.
