When working with the machine, exercise constant caution,
keep your balance, place your feet firmly on the ground,
especially on slopes. Always mow across the slope, never up or
down. When working, walk, never run.
Do not mow wet grass.
When working, hang the mower from the harness provided and
hold the handles with both hands.
A safe distance must be maintained between the operator and
the cutting element during start-up and throughout operation.
Moving parts must not be touched before they have come to a
complete stop and the engine has been switched off.
Wear protective gloves during servicing operations. Take care
not to cut yourself on the line shortening blade or the cutting blades.
In the event of an accident at work, use first aid measures
appropriate to the injury and obtain medical advice.
Always carry out a visual inspection of the machine before use
and after any fall or other impact to identify any damage. If any
abnormalities are found, do not operate the appliance and return it to
an authorised service centre.
Switch off the appliance if it starts to vibrate excessively,
become too noisy and run unevenly.
Do not use the unit with a damaged cover or housing.
If a leak or fuel leak is detected, do not start the engine, as there
is a risk of fire.
Do not run the appliance in confined spaces. The engine emits
exhaust fumes containing carbon dioxide. Inhalation of exhaust
fumes can lead to unconsciousness and death.
Do not touch hot engine parts with unprotected body parts
during and shortly after operation. The appliance heats up
considerably during operation.
Take frequent breaks from the machine for short rests and
changes in working position. Due to the effects of vibration, adhere
to the specified operating times.
Never lay the hot unit on dry grass.
Do not smoke near the petrol brushcutter, there is a risk of fire.
Precautions when working with cutting discs
When using a metal cutting disc, the disc may come into contact with a
hard object (stone, wood) and a side-to-side kickback of the scythe may
occur. The recoil can be so violent and unexpected that the unit may be
thrown in any direction and the operator may lose control of the unit. To
avoid this, it is important to:
- Hold the device firmly with both hands.
- Take care that no obstacles are lying on the ground.
- Do not use the cutting disc near fences, metal posts.
- Use well-sharpened cutting discs.
The cutting disc may cause injury to the operator as it continues to rotate
for a while after completion of work. All work may be carried out when the
disc has come to a complete stop.
Do not use the machine if the disc is found to be cracked, bent or dulled.
If such defects are found, replace the disc with a new one.

5. Purpose of the device
The machine is designed for mowing grass or similar soft vegetation as
well as cutting shrubs or young trees with stem diameters of up to 2 cm
using a suitable cutting disc.
6. Restriction on use
The appliance may only be used in accordance with the ‘Permitted
operating conditions’ below.
It is not permissible to use the appliance with the cutting tool guard
removed or damaged. Do not use the appliance during bad weather
conditions such as rain, especially if there is a risk of lightning.
Any unauthorised changes to the mechanical and electrical structure,
modifications of any kind and maintenance operations not described in
the operating manual will be considered unlawful and will void the
warranty and the declaration of conformity.
Any use which is not intended or which does not comply with the operating
instructions will result in immediate loss of warranty rights.
Permitted operating conditions
The unit is designed for outdoor use
Due to the vibration involved, uninterrupted operation must not last longer
than 30 min..

Information on vibrations and noise
The combined value of the vibration ah and the measurement uncertainty
were determined in accordance with the standard EN ISO 11806-1 and
are given in the table.
Noise emissions were determined in accordance with the standard EN
ISO 11806-1, and values are given in the table above.
Noise can cause hearing damage, always wear
hearing protection when working!
The declared total vibration/noise value has been measured according to
a standard test method and can be used to compare one device with
another. The stated vibration/noise level can also be used for a
preliminary vibration/noise exposure assessment.
Vibration/noise levels during actual use of the equipment may differ from
the declared values, depending on the use of the work tools, in particular
the type of workpiece and the need to determine operator protection
measures. To accurately estimate exposure in actual use conditions, all
parts of the work cycle must be taken into account, including periods
when the machine is switched off or when it is switched on but not used
for work.
8. Preparing for use
Carry out all maintenance with rotating parts
stationary, the engine switched off and the spark
plug wire disconnected.
Assembling the motor
Assemble the motor and boom by screwing them together with the screws
provided (Fig. A, 5).
Assembly of the right handlebar
Mount the right handlebar to the handlebar as shown in figure A (Fig. A,
9). Ensure that the holes in the handlebar and handlebar are aligned. Put
the locking screw through the holes and assemble with the nut on the
opposite side of the handlebar (Fig. D, 4).
Mounting and adjusting the handlebar
Mount the handlebar in the handlebar holder so that the handle with the
throttle trigger is on the right side. Tighten the mounting screws (Fig. A,
10; 11).
It is possible to adjust the handlebar relative to the axis of the boom and
relative to the axis of the steering wheel. To adjust the handlebar setting,
loosen the mounting screws, move the handlebar to the desired
comfortable position. Tighten the mounting screws. After the motor and
