When the machine is placed in storage for a long time, drain the fuel tank clean the parts. Move the

machine to a safe place and confirm that the engine is cooled down.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or hung rotary fitting (or other accessory). Pinching or

catching causes the rotary attachment to stop quickly, which in turn tilts the tool in the opposite direction.

Kickback is the result of improper use of the tool and / or procedures or conditions of use and can be

avoided by taking the precautions indicated as indicated below:

- Never place your principal close to the rotary accessory. The accessory may bounce off your hand.

- Do not place your body in the area where the use will move if the rebound occurs. The rebound will

propel the tool in the opposite direction to the movement.

- Sharp parts and edges tend to catch the rotating accessory and cause loss of control or kickback.

Take extreme care when using the tool on sharp edges.

Residual risks

Even if you use this product in accordance with all safety requirements, the potential risk of injury and

damage remains. The following hazards may arise:

- There are harmful health consequences resulting from the emission of vibrations if the product is used

for long periods of time or not managed adequately and properly maintained. The vibrations can produce

the so-called “white finger” disease. If any of the symptoms of "white finger" syndrome appear, see a

doctor immediately. Symptoms of the "white finger" include: numbness, loss of sensitivity, tickling,

tingling, pain, loss of strength, colour changes, or skin condition. These symptoms usually appear on the

fingers, hands or wrists. The risk increases at low temperatures. To reduce this risk, please wear gloves

and keep your hands warm. Limit the operating time.

- There is a risk of hearing loss during prolonged use, in particular if you do not wear hearing protection.

Always wear hearing protection and limit the operating time.

- Cuts if no suitable protective clothing is worn.

-Inhalation of particles and exhaust gases if a mask of protection is not worn.

-Contact with projected objects.

-Burns when touching with hot surfaces.

Intended use

This machine can be used as a trimmer with the cutting edge, and as a brushcutter with the cutting blade.

The grass trimmer must be strictly and only to cut grass or weeds that are not too dense. The brush cutter must be

used to cut hard grass, more dense weeds and small branches with a maximum diameter of 10mm.

This machine is not intended to cut bushes or others similar plants requiring the tool to get off the ground. Do not use

this tool to work other materials such as stones, clay soils, etc.
