Hydraulic System Safety
•
Seek immediate medical attention if fluid is injected

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.
