Safety Section
Fire Prevention and Explosion Prevention
Caterpillar recommends the following in order to
minimize the risk of fire or an explosion related to
the battery.
Do not operate a machine if battery cables or related
parts show signs of wear or damage. Contact your
Caterpillar dealer for service.
Follow safe procedures for engine starting with jump
start cables. Improper jumper cable connections can
cause an explosion that may result in injury. Refer to
Operation and Maintenance Manual, “Engine Starting
with Jump Start Cables” for specific instructions.
Do not charge a frozen battery. This may cause an
explosion.
Gases from a battery can explode. Keep any open
flames or sparks away from the top of a battery. Do
not smoke in battery charging areas.
Never check the battery charge by placing a metal
object across the terminal posts. Use a voltmeter or
a hydrometer.
Daily inspect battery cables that are in visible areas.
Identify cables, clips, straps, and other restraints for
damage. Replace these items if necessary. Look for
signs of the following, which can occur over time due
to use and environmental factors:
• Fraying
• Abrasion
• Cracking
• Discoloration
• Cuts on the insulation of the cable
• Fouling
• Corroded terminals, damaged terminals, and loose
terminals
Replace damaged battery cable(s) and replace
any related parts. Eliminate any fouling, which may
have caused insulation failure or related component
damage or wear. Ensure that all components are
reinstalled correctly.
An exposed wire on the battery cable may cause
a short to ground if the exposed area comes into
contact with a grounded surface. A battery cable
short produces heat from the battery current, which
may be a fire hazard.
An exposed wire on the ground cable between the
battery and the disconnect switch may cause the
disconnect switch to be bypassed if the exposed area
comes into contact with a grounded surface. This
may result in an unsafe condition for servicing the
machine. Repair components or replace components
before servicing the machine.
Fire on a machine can result in personal injury
or death. Exposed battery cables that come into
contact with a grounded connection can result in
fires. Replace cables and related parts that show
signs of wear or damage. Contact your Caterpillar
dealer.
Wiring
Check electrical wires daily. If any of the following
conditions exist, replace parts before you operate
the machine.
• Fraying
• Signs of abrasion or wear
• Cracking
• Discoloration
• Cuts on insulation
• Other damage
Make sure that all clamps, guards, clips, and straps
are reinstalled correctly. This will help to prevent
vibration, rubbing against other parts, and excessive
heat during machine operation.
Attaching electrical wiring to hoses and tubes that
contain flammable fluids or combustible fluids should
be avoided.
Consult your Caterpillar dealer for repair or for
replacement parts.
Keep wiring and electrical connections free of debris.
Lines, Tubes and Hoses
Do not bend high pressure lines. Do not strike high
pressure lines. Do not install any lines that are bent or
damaged. Use the appropriate backup wrenches in
order to tighten all connections to the recommended
torque.
