3. Lubricate new filter gasket and fill the filter with
hydraulic fluid.
4. Ensure that the filter mounting area is clean. Screw
filter on until gasket contacts mounting plate. Then
tighten filter 1/2 turn.
5. Start engine and let run for about two minutes to purge
air from the system. Stop the engine and check for
leaks.
Checking the Hydraulic Lines
and Hoses
Inspect 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.
Make sure 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.
