Warning!
Do not check for high pressure leaks with your hands or fi ngers. Use a
piece of cardboard or a thin piece of wood to detect the leak.
A high pressure stream of fl uid from a pin hole can penetrate the skin and inject hydraulic fl uid
into your blood veins.
Hydraulic Leak Test
Hydraulic lines may have high pressure fl uid in the lines, even when the lines are dis-
connected.
Remember a small leak at high pressure may be invisible yet can penetrate the skin. If this
happens get medical attention immediately, serious infection or toxic reaction can develop when
hydraulic fl uid pierces the skin.
Use caution when working with hydraulic components. Ensure there are no leaks, all fi ttings are
tight and all components are in good repair.
Use a piece of wood or cardboard as a backstop when searching for leaks,
NEVER
your
hand or fi ngers.
Always relieve pressure before disconnecting or working on hydraulic system.
