• GENERAL
  Human error is a contributing factor in most equipment related injuries. Haste, carelessness and lack of training are the
  primary causes of injuries. Most operating injuries occur because of excessive speed, loss of control, failure to observe
  warning signs, slipping or falling while entering or dismounting, a lack of berms on roadways or piles, lack of a ROPS
  or seat belt, or not watching in the direction of travel. Most maintenance injuries occur during welding or when using
  hammers or wrenches. The most common faults are improper work position, a slipped tool, missed aim, a broken tool,
  flying chips and/or no welding hood. Think before you act. A careful operator or maintenance person is the best
  insurance against an accident.
• Always wear proper safety equipment. Avoid wearing jewelry and loose fitting clothing; they could catch on moving parts which could result in serious injury or death. Hard hat, sturdy rough soled work shoes or safety shoes, ear protectors,
  reflective clothing, safety glasses and heavy gloves may be required. Consult your employer for specific safety
  equipment requirements.
• Each job site and application may have personal safety requirements. Carefully evaluate your particular application and machine for equipment such as warning lights, side view and rear view mirrors, back up alarms, fire extinguisher, rotating beacons and additional lights. If in doubt, contact your distributor.
• The machine should be equipped with a fully charged fire extinguisher. All personnel should be instructed in proper
  usage. Recharge immediately after use.
• The machine should not be serviced with anyone in the operator’s compartment unless said person is qualified to
  operate the machine and is assisting in the servicing. No unauthorized personnel should be allowed to operate, maintain or service this machine. Do not rush. Hurrying can lead to accidents. Do not jump on or off the machine. Keep two hands and one foot or two feet and one hand in contact with steps and grab handles and rails at all times. Place objects on machine from ground level before mounting machine.
  Electrical system is 12 volt negative ground. When using jumper cables, precautions must be taken to minimize
  chances of injury or damage to electrical parts.
  1. Attach one end of jumper cable to positive terminal of booster battery and other end to positive terminal of machine
  battery.
  2. Attach one end of second cable to negative terminal of booster battery and other end to machine’s frame away from
  the battery.
  3. To remove cables, reverse above sequence exactly to avoid sparks near the battery. A frozen battery can explode
  when the booster cables are attached.
  NEVER check battery charge by placing a metal object across the battery posts. The sparks could cause an explosion.
  Use a voltmeter for checking battery state of charge.
  BEFORE STARTING THE ENGINE
  Always place the transmission/steering lever in neutral and apply the neutral safety lock and lock the parking brake
  before starting. The operator must be alert, physically fit and free from the influences of alcohol, drugs or medications
  that might affect his eyesight, hearing, reactions or judgement. Observe and know the use of alternate exits from the
