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 or gangrene may result.
• Keep your body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks,
never use your hands.
