• Inspect the general condition of the plate compac-
tor. Check for loose screws, misalignment or bind-
ing of moving parts, cracked or broken parts, and
any other condition that may affect its safe opera-
tion.
• Then use a premium quality lightweight machine oil
to lubricate all moving parts.
• Clean the bottom of the compactor base as soon as
it begins to pick up soil being compacted. The unit
can not do a good job if the bottom surface is not
smooth and clean.
• Replace spark plug wire.
Checking and replacing V-belt
• To ensure optimum power transmission from the
engine to the eccentric shaft, the V-belt (k) must be
in good condition.
• If the V-belt (k) is torn, worn out or smooth, it must
be replaced.
Replacing V-belt (fig. L)
• Turn off engine.
• Engine must be cool.
• Remove the belt guard (19) to access the V-belt (k).
• Loosen the four screws on the engine and push the
motor a little bit forwards.
• Pull the old V-belt (k) off the pulleys and pull a new
belt into place correctly.
• 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.
