Precautions With The Battery

• When repairing the
electrical system, or
when arc welding,
remove the negative (-)
terminal of the battery to
stop the flow of current.
Handling High-Pressure
Hoses
• DO NOT bend or hit high-pressure hoses. DO
NOT use bent or cracked piping, tubes, or hoses.
They may burst during use.
• Repair any loose or broken hoses. Fuel and/or oil
leaks may result in a fire.

Precautions With High-Pressure Oil

• Hydraulic circuits may be pressurized. Ensure
that all pressure is released before loosening
hydraulic fittings or hoses.
• DO NOT service a system before completely
releasing the internal pressure.
• Small, high-pressure pinhole leaks are extremely
dangerous. The jet of high-pressure oil can
pierce the skin and eyes. Wear safety glasses
and thick gloves. Use a piece of cardboard or a
sheet of wood to check for oil leakage.
Maintenance Near High Temperatures And High
Pressures
• Immediately after stopping, the
engine coolant and operating
oils are at high temperature and
may be pressurized. In these
conditions, opening the system
or replacing the filters, may
result in burns or other injury. Wait for the
temperature to cool and the pressure to subside
before servicing.

Rotating Fan And Belts

• Keep a safe distance from
rotating parts, such as the
radiator fan and fan belts.
• Serious bodily injury may
result from direct
indirect contact
rotating parts and flying objects.
or
with

Waste Materials

• DO NOT dump oil or
other harmful fluids into a
sewer system, rivers, etc.
• Obey appropriate laws
and regulations when
disposing of harmful
objects, such as oil, fuel,
coolant, solvent, filters, batteries, and others.
• Drain fluids from your
appropriate containers. DO NOT drain fluids
directly onto the ground.
• This machine may be equipped with optional
High Intensity Discharge lighting lamps which
contain mercury. These lamps must be reused,
recycled or properly disposed of in accordance
with applicable local, state and federal laws.
Use of Tie-Off Anchor During Maintenance and
Repair
While working at heights
during assembly, mainte-
nance or repair of the
haul truck, workers
should wear an appropri-
ate fall protection har-
ness and attach it to a
tie-off anchor or tie-off
point.
Komatsu anchor (58B-98-75190) is available for use
with fall protection harnesses. Carefully read and
understand the harness maker's instructions before
using any fall protection harness.
The load carrying capacity of anchor (58B-97-75190)
is 2 270 kg (5,000 lbs).
NOTE: The anchor must not be used for lifting.
