Precautions When Starting Engine; Precautions In Cold Areas; Starting With Booster Cables - Komatsu HD325-7R Operation & Maintenance Manual

SAFETY

PRECAUTIONS WHEN STARTING ENGINE

Start and operate the machine only while seated.
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.

PRECAUTIONS IN COLD AREAS

Carry out the warming-up operation thoroughly. If the machine is not thoroughly warmed up before the control
levers are operated, the reaction of the machine will be slow, and this may lead to unexpected accidents.
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.

STARTING 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.
Always wear safety goggles and rubber gloves when starting
the engine with booster cable.
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.
When starting with a booster cable, carry out the starting
operation with two workers (one worker sitting in the operator'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 to
the OFF position 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 installing the
booster cables. Disconnect the 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.
For details of the starting procedure when using booster cables,
see "STARTING ENGINE WITH BOOSTER CABLE (PAGE
3-135)" in the OPERATION section.
