7. PRECAUTIONS DURING OPERATION
WARNING: Failure to follow these safety precautions may lead
to a serious accident.

STARTING WITH BOOSTER CABLES
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).
‡ 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.
‡ 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 as possible from the
battery.
Starting procedure when using booster cables ➞ See “16.3 IF BATTERY IS DISCHARGED”.
‡ 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.
CHARGING BATTERY
If the battery is handled incorrectly when it is being charged, there is danger that the battery may
explode, so follow the instructions in HANDLING BATTERY and in the instruction manual for the
charger, and always observe the following precautions.
‡ Carry out the charging in a well-ventilated place, and remove the battery caps. This disperses the
hydrogen gas and prevents explosion.
‡ Set the voltage on the charger to match the voltage on the battery to be charged. If the voltage
setting is wrong, it will cause the charger to overheat and catch fire, and this may lead to an
explosion.
‡ Connect the positive + charging clip of the charger to the positive + terminal of the battery, then
connect the negative - charging clip to the negative - terminal of the battery. Be sure to tighten
both terminals securely.
‡ If the battery charge is less than 1/10 of the rated charge, and high speed charging is carried out,
set to a value below the rated capacity of the battery.
If there is an excessive flow of charging current, it may cause leakage or evaporation of the
electrolyte, which may catch fire and explode.
