Start the brushcutter only in accordance with the instructions.

––Do not use any other methods for starting the engine!

––Use the brushcutter and the tools only for such applications as specified.

––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.

––Never operate the engine with faulty exhaust muffler.

––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 and leakage of fuel, possibly causing fire.

Refuelling

––Shut off the engine during refuelling, keep away from open flames and do not smoke.

––Avoid skin contact with mineral oil products. Do not inhale fuel vapor. Always wear protective gloves during refuelling. Change and clean protective clothing at regular intervals.

––Take care not to spill either fuel or oil in order to prevent soil contamination (environmental protection). Clean the brushcutter immediately after fuel has been spilt.

––Avoid any fuel contact with your clothing. Change your clothing instantly if fuel has been spilt on it (to prevent clothing catching fire).

––Inspect the fuel cap at regular intervals making sure that it can be securely fastened and does not leak.

––Carefully tighten the fuel tank cap. Change location to start the engine (at least 3 meters away from the place of refuelling).

––Never refuel in closed rooms. Fuel vapors accumulate at ground lever (risk of explosions).

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.
Cutting Tools
–– Use an applicable cutting tool for the job in hand.
Nylon cutting heads (string trimmer heads) are suitable for trimming lawn grass.
Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs,
underwood, thicket, and the like.
Never use other blades including metal multi-piece pivoting chains and flail
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.	12	2	Caution:
Once it occurs, the equipment is thrown sideway or toward the operator at great
			Kickback
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;			Diagrammatic
•• Never apply the segment between 11 and 12 o’clock and between 2 and
			figure
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.

Vibration

––People with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system. Vibration may cause the following symptoms to occur in the fingers, hands or wrists: “Falling asleep”

(numbness), tingling, pain, stabbing sensation, alteration of skin color or of the	Diagrammatic
skin. If any of these symptoms occur, see a physician!	figure
–– To reduce the risk of “white finger disease”, keep your hands warm during
operation and well maintain the equipment and accessories.

Maintenance instructions

––Have your equipment serviced by our authorized service center, always using only genuine replacement parts. Incorrect repair and poor maintenance can shorten the life of the equipment and increase the risk of accidents.

––The condition of the cutter, in particular of the cutting tool of the protective devices and also of the shoulder harness must be checked before commencing work. Particular attention is to be paid to the metal blades which must be correctly sharpened.

––Turn off the engine and remove spark plug connector when replacing or sharpening cutting tools, and also when cleaning the cutter or cutting tool.
