ST-45HRM CE CONCRETE PUMP— INITIAL START-UP PROCEDURE

ENGINE SPEED

10.Turn the Operation Pump/Engine switch to the “ENGINE” position (Figure 28).

Figure 28. Operation Pump Engine

Switch

13.Make sure the Operation Pump/Engine switch is in the “ENGINE“ position (Figure 28), and that only the engine is running.

14.Turn the fan switch (Figure 30) to the “ON“ position and listen for fan to start.

NOTE

The pump should not be cycling at this

 

time. Only the ENGINE should be

 

running.

11.While monitoring the tachometer (Figure 25), use the Engine Throttle Control to set the engine speed to 2550 RPM (maximum speed) using steps 8A-8C

12.The Accumulator Pressure Gauge (Figure 29) should read approximately 12.1 mPa (1,750 psi).

COOLING FAN

This section is intended to make sure the fan is working properly. Under normal conditions the fan should be turned on when the hydraulic oil temperature begins to approach 23.9° C (75° F).

15.Turn the fan switch to the “OFF“ position and listen for fan to stop. If machine exceeds 170°F or to cool the machine down, turn the operation switch (Figure 28) back to the “ENGINE“ position. Run engine at high RPM with cooling fan on for 10 to 15 minutes.

PRESSURE TEST

16.The Pressure Test switch (Figure 31) is a self-diagnostic test switch, that when activated will test the pressure of the system. This switch will be discussed in the maintenance and troubleshooting section of this manual.

HOPPER REMIXER CONTROL

A.Located to the left of the Hydraulic Temperature gauge is the Hopper Remixer Control lever (Figure 32).

B.Turn the Operation Pump/Engine switch to the “ENGINE“ position (only the engine should be running).

CAUTION

If the hydraulic oil temperature exceeds 76.7° C (170° F), shut down the pump. DO NOT continue to operate the pump. Failure to shut down the pump will result in severe damage to the pump.
