Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
