– Before starting to cut, make sure the cutting tool has reached full working speed.
– 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.

Kickback (blade thrust)
– When operating the brush cutter, uncontrolled kickbacks may occur.
– Kickbacks occur frequently when attempting to cut with the 12 to 2 o’clock section of the blade.
– Never apply the 12 to 2 o’clock section of the brush cutter blade.
– Never apply this section of the brush cutter blade to solid objects, such as bushes or trees etc. that have a diameter greater than 3 cm. Doing so will cause the brush cutter to deflect with a large amount of force,  which is extremely dangerous and may cause injury.

Kickback prevention
To avoid kickbacks, remember the following:
– Using the 12 to 2 o’clock section of the blade is extremely hazardous, especially when using metal cutting tools.
– Cutting operations using the 11 to 12 o’clock section and 2 to 5 o’clock section of the blade must only be performed by trained and experienced operators, and then only at their own risk.
The optimum cutting section for easy cutting with almost no kickback is between the 8 to 11 o’clock section of the blade.

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”.

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.
– Always check the condition of the cutter, in particular the cutter protective devices and shoulder strap, before commencing work. Particular attention should also be paid to the cutting blades, which must be  correctly sharpened.
– Turn off the engine and remove the spark plug connector when replacing or sharpening cutting tools, and also when cleaning the cutter or cutting tool.

Never straighten or weld damaged cutting tools.
– Operate the brush cutter/string trimmer with as little noise and contamination as possible. In particular, check that the carburetor is set correctly.

Fuel/Refuelling

Handling fuel
Utmost care is required when handling fuel. Fuel may contain substances similar to solvents. Refuel either in a well ventilated room or outdoors. Do not inhale fuel vapors, and avoid any contact of fuel or oil with  your skin.
Mineral oil products degrease your skin. Prolonged skin contact with these products will cause your skin to become extremely dry, which may result in various kinds of skin disease. In addition, allergic reactions may  occur.
Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately.

Fuel and oil mixture
The brush cutter engine is a high-efficiency two-stroke engine. It runs on a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded regular fuel with a min. octane value of 91 RON.
To obtain optimum engine performance and to protect your health and the environment, use only unleaded fuel!
To lubricate the engine, add two-stroke engine oil (quality grade: JASO FC or ISO EGD) to the fuel. The engine has been designed to use the specified twostroke engine oil at mixture ratio of 50:1 to protect the environment.
Additionally, long service life accompanied by reliable operation and minimum emissions are guaranteed through the use of this mixture ratio. Reliable functioning of the brush cutter cannot be guaranteed unless  this mixture ratio of 50:1 (specified 2-stroke engine oil) is strictly observed.

Correct mixture ratio:
Gasoline: Specified two-stroke engine oil = 50 : 1 or
Gasoline: Other manufacturer’s two-stroke engine oil = 25 : 1 recommended
NOTE: To prepare the fuel-oil mixture, first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughly shake the mixture before pouring it into the brush cutter tank. To ensure safe operation, do not add more engine oil than the specified amount. Doing so will only result in a higher production of combustion residues which pollute the environment and clog the exhaust channel in the  cylinder as well as the muffler. In addition, the fuel consumption will rise and the performance will decrease.
Refuelling
The engine must be switched off.
– Thoroughly clean the area around the fuel filler cap (2) to prevent dirt from getting into the fuel tank (1).
– Unscrew the fuel filler cap (2) and fill the tank with fuel.
– Tightly screw on the fuel filler cap (2).
– Clean the screw fuel filler cap (2) and tank after refueling.

Storage of Fuel
Fuel cannot be stored for an unlimited period of time.
Purchase only the quantity required for a 4-week operating period. Only use approved fuel storage containers.

Correct handling

Attachment of shoulder strap
– Adjust the strap length so that the cutter blade is kept parallel with the ground.

Detachment
– In case of emergency, push the notches (1) at both sides, and detach the equipment.
Be extremely careful to maintain control of the equipment at this time. Do not allow the equipment to be deflected toward you or anyone in your vicinity.
WARNING: Failure to maintain complete control of the machine at all could result in serious injury or DEATH.
Note: In some countries, shoulder strap does not have this detachment function.
Important operating points/stopping the cutter/trimmer
Observe the applicable accident prevention regulations.

Starting
Move at least 3 m away from the area where you refueled the equipment. Place the brush cutter on a clean piece of ground taking care that the cutting tool does not come into contact with the ground or any other objects.
