WARNING
Hydraulic oil escaping under pressure can
penetrate skin and cause injury.
• If hydraulic oil 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 oil.
• 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 that all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
