PREVENT ACCIDENTS
The majority of accidents and injuries which occur in industry, on the farm, 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 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 complete ob-
servance 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.
SWARNING
Before carrying out any maintenance operation, adjustment and or repair on machines equipped
with attachments, controlled hydraulically or mechanically, make sure that the attachment is low-
ered 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.
