Checking the Hydraulic Lines and
Hoses
Inspect the hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings, weather
deterioration and chemical deterioration. Make all necessary
repairs before operating.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Ensure that all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Get immediate medical help if fluid is injected
into skin.
