WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed
within a few hours by a doctor familiar with
this form of injury; otherwise, gangrene may
result.
• 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; never use your hands.
