Safety During The Operation Of Vibratory Plates - Wacker Neuson DPU 25 Series Operator's Manual

4 Safety
Vibrations
When manually operated machines are intensively used, long-term damage caused by vibrations cannot
be precluded.
Observe the relevant legal instructions and guidelines to minimize vibration stress.
Details on vibration stress associated with the machine can be found in the chapter Technical Data.

Safety during the operation of vibratory plates

Integrated driving mechanism
Machines with integrated driving mechanism must not be set down or stored on the transport device.
The driving mechanism is only intended for transport.
Belt guard
Never operate the machine without a belt guard!
Exposed belts and belt pulleys are dangerous and can cause serious injuries if they pull in any part of
your body or if parts are ejected.
Danger of falling over
Operate the machine so that it cannot tip over or fall down from bordered areas, edges and steps.
Load-carrying capacity of the ground
Keep in mind that the load-carrying capacity of the earth to be compressed or bed can be greatly reduced
by the effects of vibration, for example near slopes.
Avoiding crushing
When operating the machine, pay particular attention to avoid being squeezed between the machine and
an obstacle. Always look in the direction of travel!
Compacting on slopes
The following points must be observed if you plan to compact inclined surfaces (slopes, escarpments):
Always stand above the machine on a slope.

Start at the bottom of a slope (slopes that can be easily managed in an upward direction can be safely

traveled in a downward direction also).
Never stand in a position where the machine could possibly fall. A slipping or tipping machine can

cause serious injuries.
Not exceeding the maximum tilt position
Do not exceed the maximum tilt position (see chapter Technical Data).

Only operate the machine at maximum tilt for short periods of time.

If you exceed the maximum tilt, the engine lubrication system will fail and thus inevitably damage
important engine parts.
Check the effects of vibration
Compacting work in the vicinity of buildings can lead to structural damage. For this reason you must
always check the possible effects of vibrations on surrounding buildings in the run-up to work.
You must take the following points into special consideration when evaluating the effects of vibration:
Vibration behavior, sensitivity and resonance frequency of surrounding buildings.

Distance of the buildings from the vibrationsite (= worksite).

Condition of the soil.

You may need to carry out measurements to determine the vibration speed.
You must also comply with the relevant guidelines and regulations, particularly DIN 4150-3.
The foundation must also have sufficient load-bearing capacity to withstand the compaction energy. In
case of doubt involve a soil mechanics specialist in the evaluation.
Wacker Neuson is not liable for any structural damage.
