Switching off the machine
Switch off the engine in the following situations:
Before breaks.
If you are not using the machine.
Store the machine in such a way that it cannot tilt, fall or slip.
Storage location
After operation, allow the machine to cool and then store it in a sealed-off, clean
and dry location protected against frost and inaccessible to children.
Not using starter sprays
Highly flammable starter sprays pose a fire hazard.
Do not use any starter sprays.
Starter sprays are highly flammable and can cause backfiring and engine dam-
age.
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 chap-
ter Technical Data.
2.6 Safety during the operation of vibratory plates

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.

DPU 2 Safety
Operator's manual 13
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 up-
ward 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 surround-
ing 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 build-
ings.
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.
