When replacing the filters, clean the spring and bypass valves. Inspect the “O” ring for
damage and replace if necessary.
Before discarding the old filter element, examine the type of material trapped in it. This may
indicate which, if any, hydraulic system components are deteriorating.
SEMI ANNUALLY:
SUCTION FILTER
Remove and clean the hydraulic reservoir intake suction filter. This permanent screen type
filter is located inside the reservoir on the intake to the pump manifold. Access to the filter
is accomplished by removing the cover with filler neck and filter holding device from the top
of the reservoir.
Remove the “O” ring from the adapter and check it for damage or deterioration. If the ring
is at all damaged, replace it.
Clean the filter by immersing it a non-caustic cleaning solvent. Rub the scree surface with a
soft brush to dislodge accumulated foreign matter. Reinstall filter, filter hold-down device,
and cover.
