PALLET CONTROLS AND INDICATORS (Contd)
RESERVOIR SITE GLASS -- The oil level in reservoir is read by viewing
white indicator through site glass. When oil level in reservoir cannot be seen
on white indicator with all hydraulic cylinders retracted, oil must be added.
CONTROL VALVE BUTTONS -- Control valves have one or two buttons.
If it is necessary to manually operate a control valve to carry out a launch or
retrieval function, or to relieve residual hydraulic pressure, depress and hold
the appropriate control valve button(s) as necessary. Refer to WP 0002 00 for a
functional description of each control valve. Control valves KY1, KY22, and
KY23 can be held in depressed position by engaging control valve lock on each
valve. Control valve KY1 must be locked in depressed position before
manually operating all other control valves.
RESERVOIR FILTER PRESSURE GAUGE -- This pressure gauge is
mounted on external oil filter housing at side of pallet hydraulic reservoir. The
filter is good until pressure indicator moves into red zone, with LPU
operating, as indicated on pressure gauge dial.
