Pressurized fluid or air could pierce skin and cause severe injury. Refer to
operator’s manual for proper use.
To help avoid injury:
• Escaping pressurized fluid can cause injury or pierce skin.
• Before disconnecting a hydraulic line, turn engine off and operate all controls to relieve
pressure. Lower, block, or support any raised component with a hoist. Cover connection
with heavy cloth and loosen connector nut slightly to relieve residual pressure. Catch all
fluid in a container.
• Before using system, check that all connections are tight and all lines are undamaged.
• Use a piece of cardboard or wood, rather than hands, to search for leaks.
• Wear protective clothing, including gloves and eye protection.
• If you are injured, seek immediate medical attention from a doctor familiar with this type of
injury.
