SAFETY SAFETY MAINTENANCE INFORMATION Attachments 0. Appoint a leader before starting removal or installation oper- ations for attachments. Place attachments that have been removed from the machine in a stable condition so that they do not fall. And take steps to prevent unauthorized persons from entering the storage area. Work Under the Machine 0. If it is necessary to go under the work equipment or the machine to carry out service and maintenance, support the work equipment and machine securely with blocks and stands strong enough to support the weight of the work equipment and machine.
It is extremely dangerous to work under the machine if the track shoes are off the ground and the machine is sup- ported only by the work equipment. If the control levers are touched by mistake, or there is a hazard to the hydraulics, the work equipment or the machine may suddenly descend. This is extremely dangerous. Never work under the machine if the machine is not properly supported by blocks or stands. Noise 0. If the noise from the machine is too loud, it may cause temporary or permanent hearing problems. When carrying out maintenance of the engine and you are exposed to noise for long periods of time, wear ear cov- ers or ear plugs while working. When Using Hammer 0.
When using a hammer, pins may fly out or metal particles may be scattered. This may lead to serious injury. Always do as follows. 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 bro- ken pieces might be sent flying and injure people in the sur- rounding 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 0.
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 0. When repairing the electrical system or when carrying out electrical welding, disconnect the negative (-) terminal of the battery to prevent the flow of current. 2-35
