Hydraulic fluid escaping under pressure may have
sufficient force to penetrate skin and cause serious injury.
If foreign fluid is injected into the skin it must be surgically
removed within a few hours by a doctor familiar with this
form of injury or gangrene may result. Keep body and
hands away from pin holes or nozzles that eject hydraulic
10
fluid under high pressure. Use paper or cardboard, and
not hands, to search for leaks. Make sure all hydraulic
fluid connections are tight and all hydraulic hoses and
lines are in good condition before applying pressure
to the system. If leaks occur, have the unit serviced
immediately by your authorized dealer.

springs can result in serious personal injury. Springs
should be removed by an authorized technician.
