7. PRECAUTIONS DURING OPERATION
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
• 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 cherger 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 off the charger to the positive + terminal of the battery, then connect
the negative - charging clip tot 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.
