AVOID ACCIDENTS
- Most accidents, whether they occur in industry, on the farm, at home or on the highway, are caused by the failure of some individuals to follow simple and fundamental safety rules or precautions.
- For this reason MOST ACCIDENTS CAN BE PREVENTED by recognising the real cause and doing something about it before the accident occurs. Regardless of the care used in the design and construction of any type of equipment there are conditions that cannot be completely safeguarded against without interfering with reasonable accessibility and efficient operation.
- Carefully read indications, cautions and safety warning quoted in the “SAFETY RULES” section. A careful operator is the best insurance against an accident. The complete observance of one simple rule would prevent many thousand serious injuries each year. That rule is: Never attempt to clean, oil or adjust a machine while it is in motion.
ATTENTION
- On machines having hydraulically, mechanically and/or cable controlled equipment (such as showels, loaders, dozers, scrapers etc.) be certain the equipment is lowered to the ground before servicing, adjusting and/or repairing.
- 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.
PRECAUTIONARY STATEMENTS PERSONAL SAFETY
Throughout this manual and on machine decals, you will find precautionary statements (“CAUTION”, “WARNING”, and “DANGER”) followed by specific instructions. These precautions are intended for the personal safety of you and those working with you.
Please take the time to read them.
CAUTION:
The word “CAUTION” is used where a safe behavioral practice according to operating and maintenance instructions and common safety practices will protect the operator and others from accident involvement.
WARNING:
The word “WARNING” denotes a potential or hidden hazard which has a potential for serious injury. It is used to warn operators and others to exercise every appropriate means to avoid a surprise involvement with machinery.
DANGER:
The word “DANGER” denotes a forbidden practice in connection with a serious hazard.
Failure to follow the “CAUTION”, “WARNING”, and “DANGER” instructions may result in serious bodily injury or death.
MACHINE SAFETY
Additional precautionary statements (“ATTENTION” and “IMPORTANT”) are followed by specific instructions. These statements are intended for machine safety.
ATTENTION:
The word “ATTENTION” is used to warn the operator of potential machine damage if a certain procedure is not followed.
IMPORTANT:
The word “IMPORTANT” is used to inform the reader of something he needs to know to prevent minor machine damage if a certain procedure is not followed.
