General Hazard Information
Do not smoke when you service an air conditioner.
Also, do not smoke if refrigerant gas may be
present. Inhaling the fumes that are released from a
flame that contacts air conditioner refrigerant can
cause bodily harm or death. Inhaling gas from air
conditioner refrigerant through a lighted cigarette
can cause bodily harm or death.
Never put maintenance fluids into glass containers.
Drain all liquids
into a su
itable container.
Obey all local regulations for the disposal of
liquids.
Use all cleaning solutions with care. Report all
necessa
ry repairs.
Do not allow unauthorized personnel on the
equipment.
Unle
ss you are instructed otherwise, perform
mainten
ance with the equipment in the servicing
position. Refer to Operation and Maintenance
Manual, for the procedure for placing the equipment
in the servicing position.
When you perform maintenance above ground level,
u
se
appropriate devices such as ladders or man lift
machines. If equipped, use the machine anchorage
points and use approved fall arrest harnesses and
lanyards.
Pressurized Air and Water
Pressurized air and/or water can cause debris and/
or hot water to be blown out. The debris and/or hot
water could result in personal injury.
When pressurized air and/or pressurized water is
u
sed fo
r cleaning, wear protective clothing,
protective shoes, and eye protection. Eye protection
includes goggles or a protective face shield.
The maximum air pressure for cleaning purposes
mu
st be r
educed to 205 kPa (30 psi) when the
nozzle is deadheaded and the nozzle is used with
an effective chip deflector and personal protective
equipment. The maximum water pressure for
cleaning purposes must be below 275 kPa (40 psi).
Trapped Pressure
Pressure can be trapped in a hydraulic system.
Releasing trapped pressure can cause sudden
machine movement or attachment movement. Use
caution if you disconnect hydraulic lines or fittings.
High-pressure oil that is released can cause a hose
to whip. High-pressure oil that is released can cause
oil to spray. Fluid penetration can cause serious
injury and possible death.
Fluid Penetration
Pressure can be trapped in the hydraulic circuit long
after the engine has been stopped. The pressure
can cause hydraulic fluid or items such as pipe
plugs to escape rapidly if the pressure is not
relieved correctly.
Do not remove any hydraulic components or parts
un
til pr
essure has been relieved or personal injury
may occur. Do not disassemble any hydraulic
components or parts until pressure has been
relieved or personal injury may occur. Refer to the
Service Manual for any procedures that are required
to relieve the hydraulic pressure.

Always use a board or cardboard when you check
for a leak. Leaking fluid that is under pressure can
penetrate body tissue. Fluid penetration can cause
serious injury and possible death. A pin hole leak
can cause severe injury. If fluid is injected into your
skin, you must get treatment immediately. Seek
treatment from a doctor that is familiar with this type
of injury.
Containing Fluid Spillage
Care must be taken in order to ensure that fluids are
contained during performance of inspection,
maintenance, testing, adjusting, and repair of the
equipment. Prepare to collect the fluid with suitable
containers before opening any compartment or
disassembling any component that contains fluids.
Refer to Special Publication, NENG2500, “
Caterpillar
Dealer Service To
ol Catalog” for the following items:
• Tools that are suitable for collecting fluids and
equipment
that is suitable for collecting fluids
• Tools that are suitable for containing fluids and
equipment
that is suitable for containing fluids
Obey all local regulations for the disposal of liquids.
