sAfeTy...you cAN lIve WITh IT equIPMeNT sAfeTy GuIdelINes Every year many accidents occur which could have been avoided by a few seconds of thought and a more careful approach to handling equipment. You, the operator, can avoid many accidents by observing the following precautions in this section. To avoid personal injury, study the following precautions and insist those working with you, or you yourself, follow them.
• Failure to follow proper procedures when mounting a tire on a rim can produce an explosion which may result in a serious injury or death. • Do not attempt to mount a tire unless you have proper equipment and experience to do job. • Inflating or servicing tires can be dangerous. Whenever possible, trained personnel should be called to service and/or mount tires. • Always order and install tires and wheels with appropriate type and load capacity to meet or exceed anticipated weight to be placed on the equipment. • Refer to “TIRE INFLATION CHART” in your owners manual for maximum tire pressure for a Demco Grain Cart. befoRe oPeRATIoN: • Carefully study and understand this manual and the Owner’s Manual. • Do not wear loose-fitting clothing which may catch in moving parts. • Always wear protective clothing and substantial shoes. • It is recommended that suitable protective hearing and eye protection be worn. • Operator may come in contact with certain materials which may require specific safety equipment relative to handling of such materials. (Examples: extremely dusty, molds, fungus, bulk fertilizers, etc.) • Keep wheel and lug nuts tightened to specified torque.
• When halting operation, even periodically, set tractor or towing vehicles brakes, disengage PTO, shut off engine, and remove ignition key. • Be especially observant of operating area and terrain. Watch for holes, rocks, or other hidden hazards. Always inspect area prior to operation. DO NOT operate near edge of drop-off or banks. DO NOT operate on steep slopes as overturn may result. Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops. • Pick the most level possible route when transporting across fields. Avoid edges of ditches, gullies, and steep hillsides.
Reduce speed prior to turns to avoid risk of overturning. Always keep tractor or towing vehicle in gear to provide engine braking when going downhill. Do not coast. - Do not drink and drive! • Comply with state and local laws governing highway safety and movement of farm machinery on public roads. • Use approved accessory lighting, flags and necessary warning devices to protect operators of other vehicles on highway during transport. various safety lights and devices are available from your dealer. • Use of flashing amber lights is acceptable in most localities. However, some localities prohibit their use. Local laws should be checked for all highway lighting and marking requirements.
