The leveling jacks must be in the stowed position (horizontal position) when
towing or shipping the ROWPU by truck or rail.
LEVELING JACKS. (Army) The leveling jacks are secured by a swivel assembly to a movable support
bracket located under the deck of the trailer at each corner. The swivel assembly contains a springloaded pin
(Model No. 600-1) which can lock the assembly in either the vertical or the horizontal position. In the vertical
position, the jacks are used to level the trailer by raising or lowering the trailer corners as necessary. In the
horizontal position the jacks are stowed. The front jacks, when locked in the vertical position, can also be used to
assist in uncoupling the trailer from the towing vehicle. Turning the crank counterclockwise raises the jackpad;
turning the crank clockwise lowers the jackpad.
SPARE WHEEL AND TIRE CARRIER ASSEMBLY. (Army) The spare wheel and tire carrier has a
manually operated, cable-driven winch mounted on the frame structure at the rear end and underside of the
trailer. The two wheel lug nuts installed on the carrier are the same as those on the towing vehicle, thereby
enabling the use of the towing vehicles lug wrench for removal or replacement of the spare wheel tire assembly.
WATER METER. This meter is used to indicate the total number of gallons, in tenths of a gallon, of
product water the unit has produced. The number of gallons is read directly from the numerals in the small
window and the tenths of gallons from the position of the needle on the dial face. (See figure 23.)
CONTROL PANEL. The control panel consists of various gages, valves, lights, switches, and hose
connections as shown in fig. 2-4, sheet 1. Their functions are described in Table 21 (Keys 1 through 23 and 53).
CONTROL BOX. The control box consists of the pump control switches and indicator lamps as shown
in fig. 2-4, sheet 2. Their functions are described in Table 21 (Keys 24 through 43).
CIRCUIT BREAKER PANEL. The circuit breaker panel is located in the junction box and consists of
circuit breakers for the pumps, utility outlets and backwash timer as shown in fig. 2-4, sheet 3. Their functions are
described in Table 2-1 (Keys 44 through 52).
