PREVENT ACCIDENTS
The majority of accidents and injuries which occur in the workshop, at the worksite or on the road, are caused
by the failure of some individual to follow simple and fundamental safety rules or precautions. For this reason
most accidents can be prevented by recognizing the real cause and taking the necessary precautions, before
the accident occurs.
Regardless of the care used in design and construction of any type of equipment, there may be conditions
that cannot be completely safeguarded against, without interfering with reasonable accessibility and efficient
operation.
A careful operator and / or technician is the best insurance against accidents.
The careful observance of this single safety rule would be sufficient to prevent serious injuries:
Never attempt to clean, lubricate or adjust a machine while it is in motion.

SWARNING S
Before carrying out any maintenance operation, adjustment and or repair on machines equipped with attach-
ments, controlled hydraulically or mechanically, make sure that the attachment is lowered and safely set on
the ground. If it is necessary to have the equipment partially or fully raised to gain access to certain items, be
sure the equipment is suitably supported by means other than the hydraulic lift cylinders, cable and /or
mechanical device used for controlling the equipment.
