3 StartStart EngineEngine // MotorMotor

•• To start engine, switch ignition from “OFF” to “ON”.

•• The dashboard gauges should rise then zero out and then reset.

•• Push / engage both starter buttons at the same time until the engine starts, then release.

4 RoadRoad TransmissionTransmission -- NeutralNeutral

•• Ensure the Road Transmission is in neutral “N” over “N”.

•• Note – The upper letter is what the driver has selected and the lower letter is what gear the transmission is actually in.

5 EngagingEngaging thethe PumpPump TransmissionTransmission

•• Unlock (by squeezing) and slide the pump power shift lever from the “upper – ROAD” position down to the “middle” position.

•• To avoid any grinding, pause in the “middle” position for 4 to 5 seconds.

•• There should be a slight air release sound during the shifting, but it should stop upon completion.

6 EngagingEngaging thethe PumpPump TransmissionTransmission

• After pausing, continue to shift the pump power shift lever downward and into “PUMP”.

• There should be a slight air release sound during the shifting, but it should stop upon completion.

• Next, check the “Pump Engaged Light” to make sure it is “ON”.

• When this is completed, the Pump Transmission has shifted from “ROAD” to “PUMP” and the rear differential has been disengaged and the main fire pump engaged. 7 EngageEngage RoadRoad TransmissionTransmission

•• To engage the Road Transmission and start the main fire pump spinning select “D” (Drive) on the selector pad. •• The Road Transmission indicator should display “4” over “4”. •• If “4” over “4” is not displayed, then return to neutral “N” and attempt again.

• Emergency Override Procedures will be covered in another program. 8 SpeedometerSpeedometer IndicatorIndicator

•• Once the Pump Transmission and the Road Transmission have been properly aligned, the speedometer should display a speed around 20 MPH at idle and the vehicle should not move.

•• At this time the High Fan should also engage (you should hear it).

13 PressurePressure GaugeGauge

• Main Pump Pressure Gauge should read around 50 psi at idle (if pumping from the tank or if there is water in the pump).

• Note – If pumping at draft with an empty pump, the pressure gauge will read 0 psi.

• Note – If pumping from a hydrant, and already connected with keystone valve already open, this pressure will be higher than the vacuum gauge / compound gauge.

14 FlowingFlowing WaterWater

•• After the main fire pump is engaged, hose lines connected, and discharge gates opened: •• Throttle up to desired pressure (turn Throttle to the left).

•• Set Relief Valve

16 ShuttingShutting DownDown

•• When operation is completed:

•• Throttle down (turn to right) to desired pressure or until Throttle clicks twice for idle.

•• Close discharge gates

•• Return Relief Valve to highest setting.

•• TGR = Throttle, Gates, Relief

19 DisengageDisengage PumpPump TransmissionTransmission

Unlock (by squeezing) and slide the pump power shift lever from the “lower - PUMP” position up to the “middle” position.

To avoid any grinding, pause in the “middle” position for 4 to 5 seconds.

Then continue to shift the pump power shift lever upward and into “ROAD”.

There should be a slight air release sound during the shifting, but it should stop upon completion.

Note – “Pump Engaged Light” is out. 20 TurningTurning OffOff EngineEngine // MotorMotor

•• Switch the ignition switch from the “ON” position to the “OFF” position.

•• Note – It may be necessary to allow the engine / motor to idle for 3 minutes prior to turning it off (if the Engine Temperature gauge reads near or above 200 °F).
