Checking the Hydraulic Lines and
Hoses
WARNING
Hydraulic fluid escaping under pressure can
penetrate the 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
pinhole 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.
Check 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.
