Only start the petrol multi garden tool if an
attachment is connected! Remove the appropriate
transportation protection and inspect the unit in
good working condition. Never use a damaged,
poorly adjusted or serviced or not completely and
securely assembled device.
Check before use!

Once the machine has been set up properly, start the
engine as follow:
1. Turn the engine switch to the ON position. Fig. 27
2. Put the choke lever on the
3. Press the fuel pump more than 5 times. Fig. 26
4. Pull the recoil starter handle (9) 3-5 times to start the
engine. Fig. 28
Never place feet on the shaft or kneel on it.
5. Once the motor is running, briefly wait, then put the
choke lever into position.
6. To start the cutting tools, operate the release lever (8)
with the palm of your hand, and the throttle lever (11)
with your fingers. The further you push the throttle lever,
the higher the motor speed. When releasing the throttle
lever, the motor becomes idle and the cutting tools
stop. Fig.30. The cutting tools should not continue
turning and should not move when the motor is idle.
7. If there are problems, immediately turn the motor switch
(7) to "0" so the motor stops. Caution: The cutting tools
may continue turning for a few seconds. Fig.30
8. In an emergency, the safety button (m) can be pressed
from the harness. The machine then detaches imme-
diately from the carrying strap and falls to the ground.

9. If the motor is warm, you can leave the choke lever in
the "warm start and work" position.
Note: If the engine does not start up even after several
attempts, read the section „Engine troubleshooting".
Note: Always pull the starter cord out in a straight line. If
it is pulled out at an angle, then friction will occur on the
eyelet. As a result of this friction, the cable will become
frayed and will wear away faster. Always hold the starter
handle when the cable retracts.
Never allow the cable to snap back when it has been pulled
out.

m Attention: When the engine has been switched off,
the cutting unit continues running for several seconds
therefore do not touch the cutting unit until it has come
to a standstill!

9. Working instructions

Working with brush cutter / grass trimmer
• When you work with the petrol brush cutter for the first
time, familiarize yourself with the operation and control
of the petrol cutting blade without running engine.
• The design of the petrol brush cutter allows for
operation only at the right side of the user's body.
• Keep the petrol brush cutter firmly with both hands on
the handles.
• Always make sure that the cutting tool continues to
rotate briefly after the throttle has been released.
• Always so that the cutting tool no longer turns in a
proper engine idle not press down the throttle.
• Always work with high speed so you have the best
cutting results.
• Poke when working on a stone or a tree, turn off the
engine and remove the spark plug then examine the
petrol brush cutter for damage.
• Caution: Always be extra careful when working in
difficult terrain and slopes. Cut tall grass gradually so
as not to overload the unit.
• Always wear safety glasses and hearing protection
and a safety helmet.
Mowing with grass trimmer
• Use the plastic line cassette for a clean cut also at
uneven edges, fencing posts, and trees.
• Carefully advance the trimming line to an obstacle, and
use the tip of the line to cut around the obstacle. When
the trimming line comes into contact with stones, trees,
and walls, the line wears out or breaks off ahead of time.
• Swing the petrol cutting blade like a normal scythe
horizontally from right to left and back again. You define
the cutting height depending on how high you are holding
the tool.
• Never replace the nylon line with a metal wire.
RISK OF INJURIES
Automatic thread trimming (Fig. 44)
The petrol cutting blade is delivered with a filled line
cassette. This line will wear out during work. To feed new
line, forcefully press the head of the line cassette onto the
ground while the engine is running at working speed.
The line is automatically fed due to centrifugal force.
The knife at the line guard will shorten the trimming line to
the correct length. Run the trim line approach cautiously
to an obstacle and cut with the tip of the line around the
obstacle.
Mowing with brush cutter and hedge trimmer
Use the cutting blade to comb through brushwood,
rank growth, young tree populations (trunk diameter of
maximum 2 cm), and high grass.
