2Operation
2.1 Safety Precautions for the Operation
Before every shift, the operator must check the operativeness of all controls and safety elements as well as the
proper installation of all protective devices. The compactor is only allowed to be operated with all protective devices
in place. The control's functionality is not allowed to be impaired or annulled.
Before starting the compactor, the operator must take his personal noise protection measures. The engine is only
allowed to be started after is has been assured that the compactor cannot automatically start moving.
If defective safety devices or other failures which might affect the safe operation of the compactor are ascertained,
the supervisor must be informed without delay. In case of malfunctions endangering the unit's operational safety,
the machine must be turned off immediately.
During the machine's operation, the operator has to constantly supervise the operational safety of the compactor.
When running the machine , the operator is not allowed to leave the operating controls of the compactor. In
addition, he must always have a sufficient visibility on the compactor's zone of operation. The operator must be
assisted by a marshaller if the visibility on the zone of operation is restricted because of the operating conditions.
Soil compactors must be used and operated in a way ensuring their stability. The machine's stability is especially
endangered on slopes and brinks. Thus, keep clear of slopes and brinks.
When working on slopes, the operator must alway walk on the uphill side. Compaction work on slopes exceeding
the maximum gradeability of the compactor is prohibited. When working/travelling on slopes, always use extreme
precaution and drive/work directly in uphill or downhill direction.
Moist and loose bases considerably reduce the grip of the compactor on slopes. Increased danger of
accident!
Passing unevennesses or kerbs is only allowed at reduced speed. In addition, the soil compactor must be operated
in a way excluding any risk of injury caused by the handle swinging towards the operator.
