SAFETY MAINTENANCE INFORMATION SAFETY When Using Hammer When using a hammer, pins may fly out or metal particles may be scattered. This may lead to serious injury. Always do as fol- lows. If hard metal parts such as pins, bucket teeth, cutting edges, or bearings are hit with a hammer, there is a hazard that pieces might be scattered and cause injury. Always wear safety goggles and gloves. When hitting pins or bucket teeth, there is a hazard that broken pieces might be sent flying and injure people in the surrounding area. Always check that there is no one in the surrounding area.
If pins are hit with strong force, there is a hazard that the pin may fly out and injure people in the surrounding area. Welding Works Welding operations must always be carried out by a qualified welder and in a place equipped with a proper equip- ment. There is a hazard of fire or electrocution when carrying out welding, so never allow any unqualified person- nel to carry out welding. Removing Battery Terminals When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of the battery to prevent the flow of current.
