ST-45 PUMP — CONTROL BOX COMPONENTS

Figure 8. Pump Control Box Components

1.

Engine Tachometer – Monitors the engine RPM’s and

 

hours of operation for the engine.

2.

Emergency Stop Button – Press emergency stop button

 

to stop pump in an emergency.Turn knob counter clockwise

 

to disengage the stop button.

3.

Hourmeter – Display's the number of hours the pump has

 

been in use.

4.

Ignition Switch – Insert the ignition key here to start the

 

engine. Turn the key clockwise to the “ON“ position, then

 

continue turning clockwise to the “START“ position and

 

release. To stop the engine turn the key fully counter-

 

clockwise to the “STOP“ position.

5.

Battery Indicator Lamp– Indicates a low battery charge.

 

Replace or charge battery. NEVER operate the ST-45 when

 

this lamp is on.

6.

Oil Pressure Indicator Lamp– When lit, indicates correct

 

operational pressure for running the ST-45.NEVERoperate

 

the ST-45 if this lamp is off.

7.

Air Filter Indicator Lamp – Indicates the engine air filter

 

is functioning properly. NEVER operate the ST-45 if this

 

lamp is off.

8.

Direction Control Switch– This 2 position switch controls

 

the direction of flow for any mix in the pump. The center

 

position sets the pumping direction to forward and the right

 

most position sets the pumping direction to reverse.

9.

Pump Operation Switch– This 2 position switch controls

 

the operation of the pumping components and engine. The

 

center position allows the operation of the pump and

 

engine and the right most position allows only the engine

 

to operate.

10. PressureTest Switch– Activates a self-diagnostic routine which tests the pressure of the pumping system, which can be read on the Pumping Pressure Gauge.

11. Pumping Control Switch – This 3-position switch controls the pumping of the pump.The left most position is for use with the remote control unit, the center position is for normal pumping operation, and the right most position (OFF) prevents pumping.

12. Cooling Fan Switch – If hydraulic oil temperature exeeds 75° F, set the pump operation switch to engine and turn the cooling fan switch to the right most position to activate cooling fan.

13.Remote Cable Connector – Insert the remote control input cable into this connector.
