c. START Switch. This switch is used to start the engine after the glow plugs have been preheated. Hold the
switch down to start the engine, and release it as soon as the engine has started. The switch will return to its center
position when released.
d. ENGINE RPM Switch. This switch is used to adjust engine speed. Hold the switch up to increase engine speed
and down to decrease engine speed. Release the switch when the desired engine speed has been reached.
e. SPRAY NOZZLES Switches and Indicator Lights. These switches control water flow to the left and right spray
nozzles. Push the switch up to turn water flow on, and down to turn water flow off. The green indicator lights will
illuminate at both control panels when the valve to a spray nozzle is open.
NOTE
If a spray nozzle has been turned on, it must be turned off from the same control panel. It can be turned
off from the opposite control panel only by turning off the power switch. However, this will turn off the
power to all functions, including the engine.
f. WATER LEVEL LOW Indicator Light. When the water tank is nearly empty, the amber low-water indicator light
will turn on. The engine should be shut down immediately when this light comes on.
CAUTION
Continued pumping with the amber LOW WATER LEVEL indicator light on will empty the tank and may
damage the water pump shaft seals.
g. Ammeter (Rear Control Panel Only). The ammeter indicates the condition of the engine charging system when
the power switch is in the on position.
h. Tachometer (Remote Control Panel Only). The tachometer indicates the speed of the water distributor engine in
revolutions per minute (rpm).
