PRECAUTIONS WHEN STARTING ENGINE
The machine may suddenly move off and this may lead to serious personal injury or death. Always observe the
following.
• Start the engine only while sitting down in the operator's seat.
• When starting the engine, sound the horn as a warning.
• If another person is allowed on the machine, that person may sit only in the assistant's seat.
• Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.
• Check that the backup alarm (alarm buzzer when machine travels in reverse) works properly.
IN COLD AREAS
• Perform the warming-up operation thoroughly. If the machine is not thoroughly warmed up before the con-
trol levers are operated, the reaction of the machine will be slow, and this may lead to unexpected acci-
dents. Particularly in a cold weather, be sure the warm-up operation is completed.
• If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power
source. There is a hazard that this will ignite the battery and cause the battery to explode.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check
that there is no leakage of electrolyte before starting.
START ENGINE WITH JUMPER CABLES
If any mistake is made in the method of connecting the jumper cables, it may cause the battery to explode, so
always observe the following.
• Always wear protective eyeglasses and rubber gloves
when starting the engine by using the jumper cables.
• When connecting a normal machine to a failed machine
with the jumper cables, always use the normal machine
with the same battery voltage as the failed machine.
• When starting the engine with the jumper cables, perform
the starting operation with 2 workers (one worker sitting in
the operator's seat and the other working with the battery).
• When starting from another machine, be careful that the
normal machine does not contact with the failed machine.
• When connecting the jumper cables, turn the starting
switch to OFF position for both the failed machine and the normal machine. If the failed machine has a bat-
tery disconnect switch, turn it to OFF position, and turn it ON again after connecting the cables.
It is dangerous that the machine may move when the power is connected.
• Be sure to connect the positive (+) cable first when installing the jumper cables. Disconnect the negative (-)
cable (ground side) first when removing them.
• When disconnecting the jumper cables, take care not to bring the clips in contact with each other or with the
machine.
PRECAUTIONS FOR OPERATION
CHECKS BEFORE OPERATION
If the checks before starting are not performed properly, the machine will be unable to display its full perform-
ance. It is dangerous and may cause serious personal injury or death.
When performing the checks, move the machine to a wide area with no obstructions, and pay careful attention
to the surroundings. Prohibit anyone other than the operator from coming close to the machine during checks.
