WARNING: For reasons of safety, always follow these safety precautions. SAFETY If any mistake is made in the method of connecting the booster cables, it may cause a fire, so always do as follows. ! Carry out the starting operation with two workers (with one worker sitting in the operator's seat) ! Always wear safety glasses when handling tools or booster cables near the batteries. ! 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. ! Be sure to connect the positive ( [ ) cable first when installing the booster cables.

Disconnect the ground or negative ( - ) cable first when removing them. ! If any tool touches between the positive ( [ ) terminal and the chassis, it will cause sparks. This is dangerous, so be sure to work carefully. ! The final ground connection is the connection of the ground to the engine block of the problem machine. However, this will cause sparks, so be sure to connect it as far away as possible from the battery. Starting with booster cables ц See "16.3 IF BATTERY IS DISCHARGED" on page 2-71. !
