THIS ALERT SYMBOL SIGNALS IMPORTANT MESSAGES INVOLVING YOUR SAFETY. A

Most accidents, whether they occur in industry, on the farm, at home or on the road, are caused by the failure of some individuals to follow simple and fundamental safety rules and precautions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognising the real cause and doing something aboiut it before the accident occurs. Regardless of the care used in the design and construc- tion of any type of equipment, there are many conditions that cannot be completely safeguarded against without interfering in the reasonable accessibility and efficient operation. A carefull operator is the best insurance against an accident. The complete observance of one simple rule would prevent many serious accidents. The rule is simple: never attempt to clean, lubricate or maintain a machine while it is in motion. AVOID ACCIDENTS WARNING Prior to engaging in any maintenance, adjustment or repair operation on machines having hydrauli- cally, mechanically, and/or cable controlled equipment (such as shovels, loaders, dozers, excavators etc.) be certain the equipment is lowered to 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 devices used for controlling the equipment.
