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  specified.

 

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  muffler.

 

Shut off the engine during transport.

 

When transporting the equipment, always attach the cover to the cutting 

 

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.

Refueling

Shut  off  the  engine  during  refueling,  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 refueling. 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 refueling).
Never refuel in closed rooms. Fuel vapors accumulate at ground lever (risk of 

 

explosions).
Only transport and store fuel in approved containers. Make sure the fuel 

 

stored is not accessible to children.
