WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
•
If hydraulic fluid is injected into the skin,
it must be surgically removed within a few
hours by a doctor familiar with this type
of injury. Gangrene may result if this is
not done.
•
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.
•
Make sure that all hydraulic-fluid hoses
and lines are in good condition and that all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
