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.
•
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-oil hoses
and lines are in good condition, and
all hydraulic connections and fittings
are tight before applying pressure to
the hydraulic system.
