Working On Loose Ground; Parking The Machine; Towing; Working Near Batteries - Komatsu 730E Shop Manual

Working On Loose Ground

• Avoid operating the
overhangs, and deep ditches. If these areas
collapse, the machine could fall or tip over and
result in serious injury or death. Remember that
ground surfaces in these areas may be
weakened after heavy rain or blasting.
• Freshly laid soil and the soil near ditches is loose.
It can collapse under the weight or vibration of
the machine. Avoid these areas whenever
possible.

Parking The Machine

• Choose a horizontal road surface to park the
machine. If the machine has to be parked on a
slope, install wheel chocks to prevent the
machine from moving.
• When parking on public roads, provide fences
and signs, such as flags or lights, on the machine
to warn pedestrians and other vehicles. Ensure
that the machine, flags, or lights DO NOT
obstruct the traffic.
• Before leaving the machine, lower the dump
body fully, activate the parking brake, stop the
engine, and lock everything. Take the key with
you.

TOWING

• Improper towing methods may lead to serious
personal injury and/or damage.
• Use a towing device with ample strength for the
weight of this machine.
• DO NOT tow a machine on a slope.
• AFTER connecting a machine to be towed, DO
NOT allow anyone to go between the tow
machine and the disabled machine.
• Set the coupling of the machine being towed in a
straight line with the towing portion of the tow
machine. Secure it in position.
• DO NOT stand next to the towing device while
the truck is moving.
For more towing information, refer to Section 30,

General Safety & Operation

WORKING NEAR BATTERIES

Battery Hazard Prevention

• Battery electrolyte contains sulfuric acid and can
quickly burn the skin and eat holes in clothing. If
the electrolyte comes in contact with the skin,
immediately flush the area with water.
• Battery acid can cause blindness if splashed into
the eyes. If acid gets into the eyes, flush them
immediately with large quantities of water. See a
doctor immediately.
• If acid is accidentally ingested, drink a large
quantity of water, milk, beaten eggs, or vegetable
oil. Call a doctor or poison prevention center
immediately.
• Wear safety glasses or goggles when working
with batteries.
• Batteries generate hydrogen gas. Hydrogen gas
is very explosive and is easily ignited with a small
spark or flame.
• Before working with the batteries, shut the engine
off and turn the key switch to the OFF position.
• Avoid short-circuiting
through accidental contact with metallic objects,
such as tools, across the terminals.
• When removing or installing a battery, identify the
positive (+) terminal and negative (-) terminals.
DO NOT short-circuit the terminals by touching
positive to negative.
• Tighten the battery caps securely.
• Tighten the battery terminals securely. Loose
terminals can generate sparks and lead to an
explosion.
