1.2 Machine Description
The CR 7 soil compactors are machines of the walk-behind type used for compaction work in road construction and
landscape applications.
Propulsion
The CR 7 soil compactor is driven by a Lombardini Diesel engine.
Important!
Please refer to paragraph 1.3 (Specifications) for the performance details of the engine and the whole
machine.
Function
The engine (1/1) drives the vibrator via a V-belt. The vibrator is screwed down to the base plate (1/6) and sets it
vibrating. The vibrating base plate performs the vibration work and travelling motion.
Accessories
A damper plate (2.4.3) and extension plates (2.4.4) are available as optional extras.
Operation
The soil compactor is started by means of an electric starter (1/5).
The soil compactor is steered by means of the handle (1/3) holding the engine speed adjusting lever (1/12) and the
drive lever (1/2) to control the direction of travel and the infinitely variable driving speed. The spring bar (1/11) allows
to fix the handle in vertical position during work breaks and transports.

2 Operation
2.1 Safety Precautions for the Operation
Safety and protection devices
Before every shift, the operator must check the operativeness of all controls and safety elements as well as the proper
installation of all protection devices. The soil compactor is only allowed to be operated with all protection devices in
place. The control's functionality is not allowed to be impaired or neutralized.
Before starting the soil compactor, the operator must take his personal noise protection measures. Before starting the
engine, check to ensure that the soil compactor cannot slip out of control.
Conduct in Case of Failures
If defective safety devices or other failures which might affect the safe operation of the soil 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.
Conduct of the Machine Operator
During the machine's operation, the operator has to constantly supervise the operational safety of the soil compactor.
When running the machine, the operator is not allowed to leave the operating controls of the soil compactor. In addition,
he must always have a sufficient visibility on the soil compactor's zone of operation.The operator must be assisted by a
second person if, because of the operating conditions, the visibility on the zone of operation is restricted.
Stability
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.
Driving and Compacting
When working on slopes, the operator must always walk on the uphill side. Compaction work on slopes exceeding the
maximum gradeability of the soil compactor is prohibited. When working/travelling on slopes, always use extreme
precaution and work directly in uphill or downhill direction.
Moist and loose bases considerably reduce the grip of the soil 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.
Exhaust Precautions
Never inhale exhaust gasses. They contain carbon monoxide, a colorless, oderless and extremely dangerous gas
which can cause unconsciousness or death. Never operate the engine inddors or in a poorly ventilated area, such
as tunnerl, cave, etc. Exercise extreme care when operating the engine near people or animals. Keep the exhaust
pipe free of foreign objects.
