3-4. Servicing Hydraulic System. To service the hydraulic system for use, proceed as outlined in the
following steps.
a.
Position the test stand convenient to 220/440 V, 3 phase, 60 HZ power outlet.
b.
If the hydraulic fluid reservoir (2, fig. 1-4) has been filled with a preservative fluid for shipment,
drain the reservoir by removing the reservoir drain cap in the bottom of the reservoir. Make certain
drain cap is installed after reservoir has been completely drained.
c.
Drain the preservative fluid (if necessary) from the hydraulic system at each filter drain for the low
pressure filters. When completely drained, replace drain caps.
d.
If necessary, drain the preservative fluid from the high pressure pump, (4, fig. 1-2) by removing the
drain plug located in the corner of the pump case. When completely drained, replace plug. Refill
pump case with MIL-H-5606 or MIL-H-82382.
e.
Connect power cord plug to 220/440 V, 3 phase, 60 HZ outlet. Place power on switch located on
the electrical control panel in ON position. This will energize the reservoir level gage located on
the
control panel.
f.
Fill the test stand reservoir at the filler neck with hydraulic fluid, Specification MIL-H-5606 or MIL-H-
82382 until the reservoir level gage indicates 3/4 to 7/8 full.
