OPERATION
3-14.5 Pump Pressure Control With Pressure Governor (Not Pumping)
The THROTTLE (RPM) CONTROL mode allows the operator to increase engine speed when not pumping, to
increase alternator output, warm the engine, or other non-pumping operations.
NOTE: For additional information concerning the operation of specific pressure governors, refer to the
following:
• PV-P-TM350, Pierce Pressure Governor Operator’s Guide on CD-ROM and Group 2825-P-
001, Pierce Pressure Governor System (in Service Manual)
• Group 2825-P-003, Pierce Hydraulic Water Pump Pressure Controller (in Service Manual)
• Group 2825-V-001, Class 1 Pressure Governor (in Service Manual)
• Group 2825-V-002, Detroit Diesel Electronic Fire Commander (in Service Manual)
1. Select throttle (RPM) control mode.
2. Adjust desired engine speed (RPM).
Press the red button to cancel the current mode and return the engine speed to idle.
The red button also serves as the emergency stop. Practice using the emergency stop.
3-14.6 Controlling Engine Speed with Multiple Controls
Some apparatus have both a hand throttle and a pressure governor. The throttle selector switch determines which
control is ON.
If hand throttle is selected, you will control engine speed manually.
If pressure governor is selected, the pressure governor controls engine speed.
ALWAYS return the control you are not using to the IDLE position.
Transferring engine speed control between Hand Throttle and Pressure Governor can cause a jump in
engine speed.
Engine speed changes can cause discharge water pressure spikes.
Spikes in discharge pressure can cause hoses to kick with great force, causing injury.
