performing
electrical
welding,

Handling High Pressure Hoses

DO NOT bend high-pressure hoses or hit with
hard objects. DO NOT use any bent or cracked
piping, tubes or hoses. They may burst during
use.
Always repair any loose or broken hoses. Fuel or
oil leaks may result in a fire.

Precautions With High Pressure Oil

Work equipment circuits are always under
pressure.
DO
NOT
add
oil,
maintenance or inspections before completely
releasing the internal pressure.
Small, high pressure pin-hole leaks are extremely
dangerous. The jet of high-pressure oil can
pierce the skin and eyes. Always wear safety
glasses and thick gloves. Use a piece of
cardboard or a sheet of wood to check for oil
leakage.
If you are hit by a jet of high-pressure oil, consult
a doctor immediately for medical attention.
