Check Hydraulic Lines and Hoses
Check hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings or
deterioration. Makeall necessary repairs before operat-
ing the machine.
CAUTION
Keep body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not hands, to
search for leaks. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate
the skin and cause serious injury. If fluid is in-
jected into the skin, it must be surgically re-
moved within a few hours by a doctor familiar
withthistypeofinjury.Gangrenemayresultfrom
such an injury.
Flush Hydraulic System
IMPORTANT: Flush the hydraulic system any time
there is a severe component failure or the system is
contaminated. Contaminated oil may appear milky
or black or may contain metal particles.
