SECTION I. DESCRIPTION AND USE OF OPERATOR'S CONTROLS AND
INDICATORS
2.1. OPERATING CONTROLS AND INDICATORS.
2.1.1. Control Panel. (Figure 2-1).
1
FUEL GAUGE. Indicates diesel fuel quantity.
2
OIL PRESSURE GAUGE. Indicates engine oil pressure.
3
TEMPERATURE GAUGE. Indicates engine coolant temperature.
4
HYDRAULIC SELECTOR VALVE. A two position valve which in the BYPASS position returns the output
of both pumps to the reservoir and in the CIRCUIT NO 3 PRESSURE position blocks the return permitting
the full output of the two pumps to be delivered to the quick disconnect PRESSURE PORT 16 GPM
CIRCUIT NO 3.
5
HYDRAULIC SELECTOR VALVE. When this valve handle is pointed to the CIRCUIT NO 1, 8 GPM
position the output of one of the two pumps is directed to the quick disconnect fitting PRESSURE PORT 8
GPM CIRCUIT NO. 1. In the other position 16 GPM CIRCUIT NO 3, the output of this pump is directed to
the quick disconnect PRESSURE PORT 16 GPM CIRCUIT NO. 3 and to the two position hydraulic
selector valve (4).
6
PRESSURE GAUGE, CIRCUIT NO. 1. Indicates Circuit No 1 hydraulic pressure.
7
PRESSURE GAUGE, CIRCUIT NO. 2. Indicates Circuit No 2 hydraulic pressure.
8
HYDRAULIC SELECTOR VALVE. This two position hydraulic selector valve is identical in function to
valve (5) except that it controls the second hydraulic pump in the system. When this two position valve
handle is pointed to the CIRCUIT NO. 2, 8 GPM position the output of one of the two pumps is directed to
the quick disconnect fitting PRESSURE PORT 8 GPM CIRCUIT NO 2. In the other position CIRCUIT NO
3, 16 GPM, the output of this pump is directed to the quick disconnect PRESSURE PORT 16 GPM
CIRCUIT NO. 3 and to the two position hydraulic selector valve (4).
9
ROTARY STARTING SWI TCH Turn clockwise to START to start the engine without the use of
preheating. Turning counterclockwise to HEAT and holding It in that position, switches on the engine
preheaters. Turning further counterclockwise to HEAT/START position starts the engine while maintaining
the preheaters switched on. All the switch positions are momentary, when released the switch is returned
by spring force to the off position.
10
OIL PRESSURE OVERRIDE SWITCH.
Push to override the engine oil pressure safety switch when
starting.
11
STOP SWITCH. Pushbutton, momentary. Depress this pushbutton to stop the engine.
12
THROTTLE HANDLE. Pull out to increase engine RPM. Can be locked in any position by rotating
clockwise.
13
PANEL LIGHT SWITCH. Activates the panel light.
14
Contains 10 amp fuse that protects the 24 volt electric system.
15
HOURMETER. Indicates the elapsed time that the hydraulic power supply has been running.
16
AMMETER Indicates battery charge or discharge and amperage output.
