5. Process materials and operating fuels must be stowed away in receptacles or containers marked ac­cording to the respective manufacturers specifications.

Maintenance

1. Only use original spare parts. Modifications to this machine, including the adjustment of the maximum
engine speed set by the manufacturer, are subject to the express approval of Wacker. In case of non­observance all liabilities shall be refused.

2. All drive units have to be switched off before carrying out maintenance jobs. Deviations from this are only
allowed if the maintenance or jobs require a running engine.

3. When working on vibratory plates equipped with electric starter, disconnect battery before carrying out
maintenance or repair jobs on the electric parts of the machine.

4. Remove pressure from hydraulic lines before working on them. Caution: take care when removing hy­draulic lines, for the oil may be very hot (up. over 80oC). Precautions are to be taken to prevent oil from

splashing into the operator’s eyes.

5. As soon as maintenance and repair jobs have been completed all safety devices have to be reinstalled
properly.

6. Do not hose down the machine with water after each use to avoid possible malfunctions. Do not use high
pressure washers nor chemical products.

Transport

1. During transport, loading and unloading ofvibration platesby meansof lifting devices, appropriate sling­ing means or hooks have to beused onthe lifting pointsprovided forthis purpose onthe vibratoryplate.

2. The load-carrying capacity of the loading ramps has to be sufficient and the ramps have to be secure
such that they cannot turn over. Make surethat noone be endangeredby machines turningover by slip­ping or by moving machine parts.

3. When being transported on vehicles, precautions have to be taken that vibration plates do not slip or turn
over.

Maintenance checks

According to the conditions and frequency of use, vibratory plates have to be checked for safe operation at
least once a year by skilled technicians, such as those found at Wacker-service depots and have to be repaired
if necessary.

Please also observe the corresponding rules and regulations valid in your country.

DESCRIPTION

Field of application

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.

DESCRIPTION

Description of function

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(Fig. 1),at standstill(Fig. 2)and inreverse motion(Fig. 3)is possible.
This process is hydraulically controlled with the operating control handle (6) on the centre pole head (7).

Forwards Standstill Reverse

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).

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).

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.

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.

DESCRIPTION

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.

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.
