• Tension the belt (k) with the help of the adjusting
screw and ensure that the engine / belt pulley re-
main perpendicular.
• Tighten the drive belt (k) if the belt gives more than
10-15 mm (when pressing your thumb on it).
• Attach the belt guard (19) again with the two screws.
m ATTENTION!
When removing or installing the drive belt (k), be
careful not to get your fingers caught between the
belt and pulley.
Exciter oil change (Fig. L - N)
• The exciter housing is pre-serviced using Automat-
ic Transmission Fluid SAE 10W 30 or its equivalent.
Change fluid after 200 hours of operation.
• Only change the oil once the eccentric vibration
unit has cooled.
• Remove the V-belt cover (19) and the V-belt (k).
• Loosen the screws (M1 (4x) on the eccentric vibra-
tion unit housing.
• Lift the entire upper part of the plate vibrator with
the engine off the eccentric vibration unit housing.
• Remove the oil drain screw (M2) from the top of the
eccentric vibration unit, tip the eccentric vibration
unit housing and drain the oil into a collection pan.
Check the oil for any swarf, in order to avoid future
problems.
• Return the eccentric vibration unit housing to an
upright position.
• Re-fill the eccentric vibration unit housing with oil
recommended for eccentric vibration units.
m ATTENTION!
Do not overfill – overfilling can result in excessive
temperatures in the exciter.
Changing the motor oil (fig. R + W)
After 20 operating hours, the oil must be changed for
the first time, then every 100 operating hours.
To remove the oil proceed as follows:
1. Have an oil collection tray at the ready and then
open the oil drain screw (j).
2. Open the filling cap (measuring stick) (16), tilt the
machine and let the oil drain.
3. Fill the oil (0,6 l) in, check with the measuring stick
(16), and close.
4. Close the oil drain screw (j) again.
5. For storage: Pull starter slowly for 5 times, so that
the oil spreads (without ignition)
Recommended engine oil SAE 10W-30 or 10W-40
(depending on the operating temperature).
Dispose of waste oil according to your country's reg-
ulations. It is not allowed to drain waste oil onto the
ground or mix it with other waste material.

Draining the fuel tank (fig: S + Z)
Have a suitable container ready and open the drain
plug (t) of the float chamber (fig. Z). Now remove the
tank cap (12) and open the fuel tap (11). The system is
then completely empty. Close the tank cap (12) again.
Cleaning / replacing the air filter (fig O - Q)
• Unscrew the wing nut (o) and remove the air filter
cap (n)
• Check the air filter cap (n) for holes and cracks. Re-
place the damaged element.
• Unscrew the inner wing nut (p) and carefully pull out
the paper filter insert (s) with the foam filter insert
(r).
• Wipe off dirt on the inside of the filter housing with
a clean moist cloth. Make sure that no direct en-
ters the opening. Set the air filter cap (n) on the
filter housing for the duration of the filter cleaning
process.
• Carefully remove the foam filter insert (r) from the
paper filter insert (s). Check both parts for damage.
Replace the damaged inserts.
• Clean the foam filter insert (r) in warm water and
a mild soap solution. Thoroughly rinse it out with
clear water and let it dry completely.
• Immerse the foam insert (r) into clean engine oil
and press out the excess oil.
• Securely knock the paper filter insert (s) on a hard
surface to remove the dirt. Never brush out the dirt,
since it is pressed into the fibre.
• Set the foam insert (r) on the paper filter insert (s)
and install the air filter element with the seal again.
• Screw the first wing nut (p) on the paper filter insert.
• Mount the air filter cap (n) and fasten the second
wing nut (o).
m ATTENTION!: Never run the engine without or
with a damaged air filter insert. This would allow dirt
to enter the engine, which would damage the engine.
The manufacturer warranty is then invalidated.
Cleaning / replacing the spark plug (fig. T + U)
m ATTENTION! Only remove the spark plug when
the engine is cold!
Clean or replace spark plug as required.
• Remove the spark plug connector and clean any
dirt from the spark plug areas.
• Unscrew the spark plug (8) and check it.
• Check the Isolator. If there is any damage, e.g.
cracks or chips, replace the spark plug.
• Clean the spark plug electrodes with a wire brush.
• Check and set the electrode gap. To make sure
that the engine remains efficient, the spark plug (8)
must have the right electrode gap (0.7-0.8 mm).
• Manually screw the spark plug (8) in and tighten it
with the spark plug spanner (g) approximately 1/4
of a revolution.
