Hydraulic System Safety
WARNING
Injection from pressurized fluid or air can cause death or serious injury. If you are
injured, seek immediate medical attention from a doctor familiar with this type of
injury.
To help avoid injury:
• Before disconnecting a hydraulic line, shut off the engine and operate all the
controls to relieve pressure.
• Lower, block, or support any raised component with a hoist.
• Cover the connection with a heavy cloth and loosen the connector nut slightly to
relieve residual pressure. Catch all fluid in a container.
• Before using the system, check that all connections are tight and all lines are
undamaged.
• Use a piece of cardboard or wood, rather than hands, to check for leaks.
• Before using the hydraulic system, check that all connections are tight and all
lines are undamaged.
• Turn the engine off and operate all controls to relieve pressure from the system
before performing work or disconnecting a hydraulic line.
