2. Safety instruction
for the use of vibratory plates with combustion engines
2.1 General instructions
2.1.1 Vibratory plates may only be operated by persons who
∗ are at least 18 years of age
∗ are physically and mentally fit for this job
∗ have been instructed in guiding vibratory plates and proved their ability
for the job to the employer
∗ may be expected to carry out the job they are charged with carefully.
The persons must be assigned the job of guiding vibratory plates by
the employer.
2.1.2 Vibratory plates may only be used for compaction jobs. Both the
manufacturer’s operating instructions and these safety instructions
have to be observed.
2.1.3 The persons charged with the operation of vibratory plates have to be
made familiar with the necessary safety measures relating to the
machine. In case of extraordinary uses the employer shall give the
necessary additional instructions.
2.1.4 This machine generates noise that exceeds the country-specific
permissible noise levels (individual rating level). It may therefore be
necessary to wear ear protection
2.2 Operation
2.2.1 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.
2.2.2 The function of operation levers or elements is not to be influenced or
rendered ineffective.
2.2.3 During operation the operator may not leave the control elements.
2.2.4 The operator has to stop the engine of the vibratory plate before going
on breaks. The machine has to be placed such that it cannot turn over.
Safety instruction
SV00069GB.fm 9
2.2.5 Stop engine before filling fuel tank. When refilling fuel tank, do not
allow fuel to come into contact with the hot part of the engine or spill
onto the ground.
2.2.6 Do not smoke or handle open fire near this machine.
2.2.7 The tank lid must fit tightly. Shut fuel cock if available when stopping
the engine. For long distance transports of machines operated by fuel
or fuel- mixtures, the fuel tank has to be drained completely.
Leaky fuel tanks may cause explosions and must therefore be
replaced immediatelly.
2.2.8 Do not operate this machine in areas where explosions may occur.
2.2.9 Make sure that sufficient fresh air is available when operating vibratory
plates equipped with combustion engines in enclosed areas, tunnels,
galleries and deep trenches.
2.2.10 During operation keep your hands, feet and clothes away from the
moving parts of the vibraton plate. Wear safety shoes, and eye
protection glasses in case of trench operation where falling sand
stones maybe ejected.
2.2.11 When working near the edges of breaks, pits, slopes, trenches and
platforms, vibratory plates are to be operated such that there is no
danger of their turning over or dropping in.
2.2.12 Make sure the soil or subsoil to be compacted has a high enough load
carrying capacity.
2.2.13 Use appropriate protective clothing while working or while carrying out
maintenance work.
2.2.14 When traveling backwards the operator has to guide the vibration plate
laterally by its guide handle so that he will not be squeezed between
the handle and a possible obstacle. Special care is required when work
ing on uneven ground or when compacting coarse material. Make sure
of a firm stand when operating the machine under such conditons.
2.2.15 Vibratory plates are to be guided such that hand injuries caused by
solid objects are avoided.
2.2.16 Vibratory plates have to be guided such that their stability is
guaranteed.
2.2.17 Machines with integrated transport trolley may not be parked or stored
on the trolley. This device has only been designed to transport the
machine.

2.3 Safety checks
2.3.1 Vibratory plates may only be operated with all safety devices installed.
2.3.2 Before starting operation, the operator has to check that all control and
safety devices function properly.
2.3.3 If defects in the safety equipment or other defects are detected which
impair the safe operation of the internal vibrator, the supervisor is to be
notified without delay.
2.3.4 The machine must to be switched off immediately in case of defects
jeopardizing the operational safety of the equipment.
2.3.5 Process materials and operating fuels must be stowed away in
receptacles or containers marked according to the respective
manufacturers specifications.
2.4 Maintenance
2.4.1 Only use original spare parts. Modifications to this machine including
the adjustment of the maximum speed set by the manufacturer are
subject to the express approval of WACKER. In case of
nonobservance all liabilities shall be refused.
2.4.2 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.
2.4.3 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.
2.4.4 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 80° C). Precautions are to be taken to prevent oil
from splashing into the operator’s eyes.
2.4.5 All safety devices must be reinstalled properly immediately after
maintenance and repair jobs have been completed.
2.4.6 Do not hose down the machine with water after each use to avoid
possible malfunctions. Do not use high pressure washers nor chemical
products.
Safety instruction
SV00069GB.fm 11
2.5 Transport
2.5.1 During transport, loading and unloading of vibration plates by means
of lifting devices, appropriate slinging means or hooks have to be used
on the lifting points provided for this purpose on the vibratory plate.
2.5.2 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
sure that no one be endangered by machines turning over by slipping
or by moving machine parts.
2.5.3 When being transported on vehicles, precautions have to be taken that
vibration plates do not slip or turn over.
2.6 Maintenance checks
2.6.1 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.
