HIGH-PRESSURE FLUIDS
FIG. 1: AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin
causing serious injury.
The vehicle must be stopped and cooled before
checking fluids. Use caution when removing radiator
caps, plugs, grease fittings or pressure taps.
Never open pressure lines when they are under
pressure. Release all pressure before doing
maintenance or repairs on any pressure system.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten all
connections before applying pressure.
FIG. 2: Search for leaks with a piece of wood or
cardboard. Protect hands and body from high pressure
fluids. Do not use your hands!
Never open hydraulic lines or fuel lines when they are
under pressure. Hydraulic fluid or diesel fuel under
pressure can cut the skin, cause bad burns, eye injury
or skin irritation.
If an accident does occur, get medical help immediately

Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
Doctors unfamiliar with this type of injury should
reference a knowledgeable medical source.
