Fluid or air pressure could pierce skin and cause injury or
death. Stay away.
NOTICE: Escaping pressurized fluid can cause injury or pierce skin and poison.
• 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.
• Fluid leaks can be hard to detect. 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.
