Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
•
Make sure 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 pin
hole 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.
•
Seek immediate medical attention if fluid
is injected into skin.
