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 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 all hydraulic fluid hoses
and lines are in good condition and
all hydraulic connections and fittings
are tight before applying pressure to
hydraulic system.
