chine will remain stationary.
Choke lever (16) (Fig. 9)
• Warm engine / choke open:
• Cold engine / choke closed:
Note: The closed position of the choke lever enriches
the fuel mixture for starting a cold engine.
The open position provides the correct fuel mixture
for normal operation after starting and for restarting a
warm engine.
Fuel valve (15) (Fig. 9)
• Open fuel valve:
• Fuel valve closed:
1. Check the engine oil and petrol levels. See sec-
tions 10.1 and 10.2.
2. Before compacting, always remove the drive
mechanism and store it in a place outside the
working area.
3. Set the choke lever (16) to closed (open when the
engine is warm). Note: As soon as the choke le-
ver (16) is opened, the plate compactor starts to
vibrate at half throttle.
4. Open the fuel valve (15).
5. Set the throttle (2) to "half throttle" (= middle posi-
tion between "fast" and "slow").
6. Set the gear lever (26) to the middle position, i.e.
"neutral".
7. Set the ON/OFF switch (23) to ON.
8. Pull strongly on the starter rope (8) and let it wind
back in slowly.
9. Once the engine is running, slowly close the choke
lever (16). And thus put it in the operating position.
10. Move the gear lever (26) to the position for the de-
sired direction of travel, as described in 11.2.
11. Set the throttle (2) to the working position.
12. plate compactor starts to work.
10.2 Operation
Forward and backward movement
The direction of movement is determined using the
shift lever (26). Depending on the position of the shift
lever (26), the plate compactor compacts in a forward
or backward motion.
1. Push the shift lever (26) forward to compact in the
forward direction.
2. Pull the shift lever (26) backwards to compact in
reverse.
m ATTENTION!
Do not use the plate compactor on concrete or ex-
tremely hard, dry, compacted surfaces. The plate com-
pactor then tends to jump and does not vibrate. This
can damage both the plate compactor and the engine.
The number of repetitions necessary for a desired
compaction result depends on the type and moisture of
the substrate. Maximum compaction has been reached
when you notice a very strong recoil.
A certain amount of moisture in the ground is neces-
sary. However, excessive moisture can cause small
parts to stick together and prevent good compaction.
Let the ground dry a little if it is extremely wet.
A very dry floor raises a lot of dust when working with
the plate compactor. Adding moisture can improve
compaction and reduce air filter maintenance.
Compaction with rubber pad
When using the plate compactor on paving stones,
fit the rubber pad with fastening bar (20) to prevent
chipping and abrasion of the stone surface (see 9.3).
You can prevent damage to slabs and natural stones
when vibrating by fitting a rubber pad under the plate
compactor. Remove the rubber pad when compacting
loose, granular soils and for blacktop repair work.
When bedding in with the black rubber pad, discolour-
ation of the material surface may occur.
Compaction without rubber pad
If the plate compactor is operated without a rubber pad,
screw the screws (21) into the base plate (10) to prevent
damage to the holes.
Notes when compacting
The following notes must be followed when ground is
compacted on slopes (mounds, embankments):
• Approach inclines only from the very bottom (an in-
cline that can be easily overcome upwards can also be
compacted downwards without risk).
• The operator must never stand facing the downward
direction.
• ATTENTION: A maximum incline of 25° shall not be
exceeded. If this increase is exceeded, the engine
lubrication system may fail (spray lubrication and
therefore failure of important engine components).
