Pressure Air And Water; Trapped Pressure; Fluid Penetration; Containing Fluid Spillage - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Pressure 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 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. Trapped pressure can cause sudden equipment 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.
When you check for a leak, use a board or cardboard. 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 obtain 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.
Obey all local regulations for the disposal of liquids.
