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
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
(Figure
• Use cardboard or paper to find
hydraulic leaks.
• Safely relieve all pressure in the
hydraulic system before performing
any work on the hydraulic system.
• 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.
