4. Open the fuel valve (15).
5. Set the throttle (2) to "half throttle" (= middle po-
sition between "fast" and "slow").
6. Set the ON/ON switch (23) to OFF.
7. Pull strongly on the starter rope (8) and let it wind
back in slowly.
8. Once the engine is running, slowly close the
choke lever (16). And thus put it in the operating
position.
9. Set the throttle (2) to the working position.
10. Plate vibrator starts to work.
11.2 Operation
When using the machine, use the guide bar with handle
(1) to steer it.
Run the engine at full throttle, using the throttle (2). In
doing so, the plate moves forward by itself at normal
speed. When working on inclines, push the plate vibra-
tor forward slightly.
When working on sloping surfaces, reduce the speed
by holding the plate vibrator back.
m ATTENTION!
Do not use the plate compactor on concrete or ex-
tremely hard, dry, compacted surfaces. The plate vi-
brator then tends to jump and does not vibrate. This
can damage both the plate vibrator 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 vibrator. Adding moisture can improve com-
paction and reduce air filter maintenance.
Compaction with rubber pad
When using the plate vibrator on paving stones, fit the
rubber pad (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
vibrator. Remove the rubber pad when compacting
loose, granular soils and for blacktop repair work.
38 | GB
When bedding in with the black rubber pad, discolour-
ation of the material surface may occur.
Compaction without rubber pad
If the plate vibrator is operated without a rubber pad,
screw the screws (21a) into the fastening strip (21) and
the base plate (20) 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 20° shall not be
exceeded. If this increase is exceeded, the engine
lubrication system may fail (spray lubrication and
therefore failure of important engine components).
11.3 Stopping the engine
Emergency stop
To stop the engine in an emergency situation, move the
engine switch (23) to the OFF position.
Switching off under normal conditions:
1. Return the throttle (2) to the idle position to stop the
plate compactor from moving.
2. Let the engine cool down for a minute or two before
stopping it.
3. Move the ON/OFF switch (23) to the"OFF" position.
m ATTENTION!
Do not move the choke lever (16) to the "closed" po-
sition to stop the engine. This can lead to a misfire or
engine damage.
11.4 Idle speed
Reducing the engine speed when idling extends the
engine's operating time, saves petrol and reduces the
noise level of the plate vibrator.
1. Move the throttle (2) to the "idle"", position to re-
duce the load on the engine when not compacting.
