Put labels on disconnected hydraulic lines and
hoses for proper installation after repairs are completed.
5.
Note the position of hydraulic fittings (especially el-
bow fittings) on hydraulic components before removal.
Mark parts if necessary to make sure they will be aligned
properly when reinstalling hydraulic hoses and tubes.
Check Hydraulic Lines and Hoses
Check hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration and/or chemical deterioration.
Make all necessary repairs before operating sweeper.
WARNING
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
with this type of injury. Gangrene may result from
such an injury.
