Komatsu — Starting Precautions

SAFETY Battery Precautions If any mistake is made in the method of connecting the booster cables, it may cause the battery to explode, so always do as follows. When working on the electrical system, disconnect the negative (- ) battery cable first then the positive (+) battery cable last. On completion of work, reconnect the positive (+) cable first then the negative (-) cable last. Starting Engine with Booster Cables When starting with a booster cable, carry out the starting operation with two workers (one worker sitting in the operator's seat and the other working with the battery). When starting from another machine, do not allow the two machines to touch.

When connecting the booster cables, turn the starting switch OFF position for both the normal machine and problem machine. There is a hazard that the machine will move when the power is connected. Be sure to connect the positive (+) cable first when installing the booster cables. Disconnect the negative (-) cable (ground side) first when removing them. When removing the booster cables, be careful not to let the booster cable clips touch each other or to let the clips touch the machine. Always wear safety glasses and rubber gloves when starting the engine with booster cables.

When connecting a normal machine to a problem machine with booster cables, always use a normal machine with the same battery voltage as the problem machine. Always cover battery terminals. The battery compartment should never be used for storage of items. Starting Precautions Never try to start the machine by tampering or shorting the starter terminals. Accidental movements of the machine could cause injury or even death. PC350LL-7E0 1-41
