4. Description
4.1 Applications
The vibratory plate has been designed for the compaction of almost
every type of soil, both in trenches as well as surface compaction. In
addition, it is possible to vibrate paving stones an concrete blocks by
using extension plates up to 86 cm (accessories).
Extremely cohesive as well as frozen soils are not suitable for
compaction. An authorised specialist must give permission for the
ground in question to be compacted.
4.2 Max. admissible inclination

Description
T01005GB.fm 13
4.3 Description of function
4.3.1 The vibration required for compaction is produced by the exciter (13)
which is firmly joined to the lower mass (5). This exciter (13) is
designed as a central vibrator with aligned vibrations. Such a principle
permits the direction of vibration to be changed by turning the eccentric
weights (15). In this way an infinitely variable transition between
vibration in forward motion , at standstill and in reverse motion is
possible. This process is hydraulically controlled with the operating
control handle (6) on the centre pole head (7).
4.3.2 The drive engine (1) anchored to the upper mass (4) drives the exciter
(13). The torque is transmitted by means of a friction connection
through the centrifugal clutch (11) and the exciter V-belt (12).
4.3.3 The centrifugal clutch (11) interrupts flow of power to the exciter (13)
at low engine speed and thus permits perfect idling of the drive engine
(1).
ReverseForwards Standstill

Description
T01005GB.fm 14
4.3.4 The automatic V-belt pulley (10) combined with the centrifugal clutch
(11) ensures optimum tension of the exciter V-belt (12) during
operation and relief of the tension of the exciter V-belt (12) when the
machine is being relocated or transported.
4.3.5 Moreover, the automatic V-belt pulley (10) automatically adapts to the
V-belt flanks in line with the wear and thus makes the entire drive from
the engine (1) to the exciter (13) maintenance-free (see chapter
Exciter V-belt).
4.3.6 The speed of the drive engine (1) can be infinitely varied by remote
control on the throttle control lever (8). The upper (4) and lower (5)
masses are connected to each other by 4 vibration-damping rubber
metal shock mounts (14). This damping system prevents the very high
frequencies from being transmitted to the upper mass (4). As a result
the functionability of the drive engine (1) is retained in spite of the high
compaction performance. The drive engine (1) works on the diesel
principle; it is started electrically by a pinion starter (3), draws in the
combustion air through an air filter, dry (9) and is air-colled.
4.3.7 To facilitate the starting procedure (at very low temperatures, with
hand start) the drive engine (1) has an automatic decompression
mechanism (2). It ensures that compression is very low during the
cranking operation but steadily increases after a few revolutions when
it then switches over to full compression.

5. Transport to work site /Recommendations on compaction
Warning
Improper use can result in injury or serious material damage.
∗Read and follow all the safety instructions at the beginning of this
operator's manual, see chapter Safety information.
5.1 Transport to work site
Danger
Danger of fire and explosions by fuel!
Any fuel that escapes can ignite and cause severe burns.
∗Lift and move the machine in the upright position.
Requirements:
∗When transporting the vibrating plate compactor, use only suitable
hoisting gear with a minimum load-bearing capacity, see Technical
data.
∗Always turn off the motor during transportation!
Note
We recommend that the fuel tank be emptied and the carburetor run
dry prior to transporting it. Fuel could run out, e.g. if the machine is
tilted.
∗Vertically set guide handle head and lock into place.
Warning
Danger due to the machine falling!
If the machine falls, it can cause severe injury such as crushing.
∗Only use suitable and tested hoisting gear and lifting tackle
(safety load hooks) of sufficient lifting capacity.
∗Attach the machine firmly to the hoisting gear.

Transport to work site /Recommendations on compaction
T01002GB.fm 16
∗Only attach suitable tackle at the central lifting point (16) provided. The
central lifting point is located exactly above the centre of gravity of the
machine. The central lifting point can be displaced rearwards (18),
given an application in which the height of the machine is of
importance (torque wrench setting = 85 Nm).
∗During transport on the loading area of a vehicle, tie down the vibration
plate using the lugs (17).

T01002GB.fm 17
5.2 Recommendations on compaction
5.2.1 Ground conditions
The max. compaction depth depends on several factors relating to the
ground condition, such as moisture, grain distribution etc,
it is therefore not possible to specify exact values.
Recommendation: In each case determine the max. compaction
depth with compaction tests and soil samples.
5.2.2 Compaction on slopes
The following points are to be observed when compacting on sloped
surfaces (slopes, embankments):
∗Only approach gradients from the bottom (a gradient which can be
easily overcome upwards, can also be compacted downwards without
any risk).
∗The operator must never stand in the direction of descent.
∗The max. gradient of 25omust not be exceeded.
A tilt in excess of this angle could lead to a stopping of the engine due
to the automatic low oil shut-off system. A restarting of the engine can
only take place after the valve lever at the oil filter housing has been
actuated once.
Right ! Wrong!

6. Operation
Warning
Improper use can result in injury or serious material damage.
∗Read and follow all the safety instructions at the beginning of this
operator's manual, see chapter Safety information.
6.1 Starting
6.1.1 Starting requirements:
Engine oil:
Check the oil level with the dipstick (19). Add oil (see Technical data)
through the filler neck (21) as needed.
The machine must be level and the engine stopped before proceeding
with the oil level check.
Fuel:
When pouring diesel fuel into the fuel nozzle (20), maintain absolute
cleanliness. Impurities in the fuel can cause breakdowns in the
injection system and premature clogging of the fuel filter.
Only refuel the machine when it’s engine is stopped.
Never refuel the machine close to open flames or ignitable sparks and
do not smoke.
Only use pure, clean fuel and clean filling vessels.
Do not spill any fuel.
