Pressurized air and/or water can cause debris and/or hot water to be blown out. This could result in
personal injury.
When pressurized air and/or pressurized water is used for 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 must be reduced 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 until pressure 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.
