1 Main Fire Pump Engagement Shifting Into Pump 2006 / 2007 KME 1

2 Battery Switch Ensure battery switch is turned on to BOTH. 2

3 Ensure Maxi (Parking) Brake Set Maxi (Parking) Brake must be set or the Pump Transmission will not engage and the Road Transmission will not lock into 4 th gear. To set Maxi (Parking) Brake pull out knob. 3

4 Start Engine / Motor 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

5 Road Transmission - Neutral 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

6 Engaging the Pump Transmission 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

7 Engaging the Pump Transmission 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

8 Engage Road Transmission 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

9 Speedometer Indicator 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). 9

10 Dashboard Light Indicator OK TO PUMP light should illuminate on the dashboard behind the steering wheel. 10

11 Manual Pump Override Handle Upon exiting the cab, notice the Manual Pump Override handle is extended out on the Engineer s Panel (below the 2½ 2 auxiliary suction port). 11

12 Engineer s s Panel Lights Below the Throttle knob on the Engineer s s Panel the MAIN PUMP ENGAGED light should illuminate. Note Do NOT throttle up if light is not on. Note If light is illuminated and Throttle does not operate, ensure Throttle is locked out by turning it to the right until it clicks twice to reset the throttle, then attempt again. 12

13 Engineer s s Panel Lights At the top of the Engineer s s Panel, the PUMP LIGHT should illuminate. This is the light in the middle of the panel lights. 13

14 Pressure Gauge 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

15 Flowing Water 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 15

16 Check All Gauges Vacuum / Compound Gauge Pressure Gauge Tachometer Fuel Oil Pressure Engine Temperature Transmission Temperature Manifold Discharge Pressure Gauges Large Diameter Discharge Pressure Gauges (ALL) Relief Valve Setting 16

17 Shutting Down 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 17

18 Disengaging Pump Return to the cab. Disengage Road Transmission return to neutral N by pressing N on the Road Transmission selector pad. Ensure the indicator displays N over N. 18

19 Speedometer and Dash Light Speedometer should zero out. OK TO PUMP dashboard light should go out. High fan should stop (noise level diminish). 19

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

20 Disengage Pump Transmission 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

21 Turning Off Engine / Motor 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). 21

22 Battery Switch Ensure battery switch is turned to OFF. 22

23 Pump Engaged Indicators Pump Engaged Light on Pump Transmission Lever Panel illuminates Road Transmission locks into 4 over 4 Dashboard OK TO PUMP light illuminates Speedometer reads around 20 MPH with no vehicle movement High fan engages (noise increases) Manual Override Lever on Engineer s s Panel extends out OK TO PUMP light on Engineer s s Panel illuminates Pump Light at top of Engineer s s Panel illuminates Pressure Gauge displays around 50 psi at idle (if water in pump) 23
