Note: Cleanliness is a key factor in a successful
repair of any hydraulic system. Thoroughly
clean all exposed surfaces prior to any type
of maintenance. Cleaning all parts by using
a solvent wash and air drying is usually
adequate. As with any precision equipment,
all parts must be kept free of foreign material
and chemicals. Protect all exposed sealing
areas and open cavities from damage and
foreign material.
When using a Bi-Directional Flow Test Kit,
determiningdirectionalowisnotnecessary.
Theowmetermaybeconnectedineither
direction into the forward and reverse high
pressure system lines.

securely. This test is performed on the
machine’s high pressure system. Failure to
comply could result in serious injury.
