TO PREVENT ACCIDENTS

The majority of accidents and injuries which occur in industry, at home 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 ACCI-

DENTS 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 oper-

ation.

A careful operator and / or technician is the best insurance against accidents. The complete observance of one

simple rule would prevent many thousands of serious injuries each year.

This rule is: never attempt to clean, lubricate or adjust a machine while it is in motion.

SWARNING

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.
