General Hazard Information
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. Flu
id 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 rapi
dly if the pressure is not relieved correctly.
Do not remove any hydraulic components or parts
until press
ure has been relieved or personal injury
may occur. Do not disassemble any hydraulic
components or parts until pressure has been relieved
or persona
l 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.
Contain ing Flui d 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 Tool Catalog” for the following items:
•
Tools that ar e s
uitable 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.

Caterpillar equipment and replacement parts that are
shipped from Caterpillar are asbestos free. Caterpillar
recommends the use of only genuine Caterpillar
replacement parts. Use the following guidelines
when you handle any replacement parts that contain
asbestos or when you handle asbestos debris.
Use caution. Avoid inhaling dust that might be
generated when you handle components that contain
asbestos fibers. Inhaling this dust can be hazardous
to your health. The components that may contain
asbestos fibers are brake pads, brake bands, lining
material, clutch plates, and some gaskets. The
asbestos that is used in these components is usually
bound in a resin or sealed in some way. Normal
handling is not hazardous unless airborne dust that
contains asbestos is generated.
If dust that may contain asbestos is present, there
are several guidelines that should be followed:
•
Never use compressed air for cleaning.
•
Avoid brushing materials that contain asbestos.
•
Avoid grinding materials that contain asbestos.
•
Use a wet method in order to clean up asbestos
materials.
•
A vacuum cleaner that is equipped with a high
efficiency particulate air filter (HEPA) can also be
used.
