10. Start on the unit
Do not start the unit until it has been completely assem-
bled.
m Danger of injury!
Only start the petrol multi garden tool if an attach-
ment is connected! Remove the appropriate trans-
portation 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!
• Check the safe condition of the device:
• Check the device for leaks.
• Check the device for visual defects.
• Check that all parts of the device have been securely
fitted.
• Check that all safety devices are in proper condition.
Start Fig. 60, 26 - 30
Once the machine has been set up properly, start the en-
gine 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 throt-
tle lever, the higher the motor speed. When releas-
ing 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.

8. In an emergency, the safety button (m) can be
pressed from the harness. The machine then detach-
es immediately from the carrying strap and falls to
the ground. Fig. 60
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.

Note: Do not start the motor in tall grass.
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 opera-
tion 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 ro-
tate 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 cut-
ting 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 dif-
ficult 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 un-
even 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 horizon-
tally 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 cas-
sette. 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 ob-
stacle 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 maxi-
mum 2 cm), and high grass.
• While using metal cutting tools, there is generally a risk
of recoil, when the tool hits a solid obstacle (stones,
trees, branches, etc.). Thereby, the tool is hurled back-
wards against the rotating direction.
