SAFETY SAFETY MACHINE OPERATION As there is a hazard that sparks will be generated, always do as follows. Do not let tools or other metal objects make any contact between the battery terminals. Do not leave tools or other metal objects lying around near the battery. Always disconnect the negative (-) terminal (ground side) first when removing the battery; when installing the battery, connect the positive (+) terminal first, and connect the ground last. Tighten the battery terminals securely. Flammable hydrogen gas is generated when the battery is charged, so remove the battery from the chassis, take it to a well-ventilated place, and remove the battery caps before charging it.
Tighten the battery caps securely. Install the battery securely to the determined place. Starting Engine with Booster Cables 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 starting with a booster cable, carry out the starting operation with two workers (one worker sitting in the opera- tor'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 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 install- ing the booster cables. Disconnect the ground or 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 goggles and rubber gloves when start- ing 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. For details of the starting procedure when using booster cables, see Starting Engine With Booster Cables (PAGE 3-104) in the OPERATION section.
