Maintenance FAQ

Frequently Asked Questions about fire apparatus. 


1. Do not open throttle light- this light is located near the pump operator’s position. This light will be illuminated when the truck is in neutral with the park brake set and or when the truck is ready to pump. This light is NOT an Ok to pump light; it simply indicates that if the throttle is advanced the truck will not drive away. This indicator is useful on vehicles not equipped with a high idle feature where the operator wishes to raise engine rpm to boost alternator output while not pumping. 

2. Towing procedure- before towing the vehicle it is recommended that the water tank be emptied and that only the towing devices shall be used (tow hooks, tow eye’s) – nothing else will be warranted  

3. Tank refill procedure- it is vendor recommendation that when filling the booster tank, the operator does not go over 100 psi fill pressure- tank may burst and/or fill line is not rated for high pressure 

4. Washing products to use / not to use- see delivery manuals for instructions 

5. Periodically check fasteners- it is our recommendation that all fasteners are checked for tightness upon delivery and periodically to prevent unnecessary damage or loss of bolt-on accessory such as (wheel covers, trim pieces, lens covers) 

6. Blocking mode / scene mode- while all warning lights are functioning, the vehicle will switch from scene mode to blocking mode by applying the parking brake. During this switch all white warning lights will be disabled.  

7. Master emergency switch- the master emergency switch that will turn on all warning lights may need to be turned on in order to use auxiliary electrical items if this switch is specified to do so by the customer. EXAMPLES: directional light bar, unity lights  

8. Turn signals / marker lights- on some vehicles there will be an amber light installed forward of the rear wheels, this light is a turn signal not a marker light. The marker lights are usually located in the pump panel area 

9. Work light switches- the work light switches will turn on all work lights and step lights at that location. All these lights including the ground lights will be turned off automatically once the parking brake is released – other lights may be included at customer request 

10. Door ajar light (related items tied into) - the door ajar flasher in the cab may have more than just the cab and body doors tied into it. Some other items that may be tied into this light may be ladder compartment door, ladder rack, fold-a-tank rack, and extendable deck gun. 

11. Headlight flasher operation- headlight flashers will operate when the headlights are not being used and the master emergency switch is on. When the headlights are on low beams the high beam light will flash. When the high beams are on the headlight flashers will not work 

12. Cab tilt locks- when the cab is lowered on a custom chassis you must make sure that the cab is getting locked down in the cradle. The cab is not locked down once the cab stops moving. You must hold the lowering button for about 5-7 seconds for the latches to lock the cab down 

13. Transmission mode button programmed/ not programmed- the transmission keypad used on some of the chassis will utilize the mode button on the keypad. Depending on how the specifications read the mode button may or may not be used. The mode button is used to shift the transmission into the highest gear allowed. If the mode button is disabled the transmission will automatically shift to the highest gear once the transmission is put into drive 

14. Heater shut-off valve- it is recommended that on custom chassis if air conditioning is furnished, in the summer time that the heater valve is shut off. This valve is usually located under the cab in front of the front wheel on the passenger side. This will prevent the circulation of coolant into the heater/air conditioner. Once cold weather has arrived the valve will need to be opened in order to have heat in the chassis 

15. 4th gear lock up- when shifting the vehicle into pump gear, the transmission gear display will go into 4th gear; this is called 4th gear lock up. This will tell the operator that the pump has been successfully shifted into pump gear. This display should not show any other gear other than 4th. If the display shows any other gear the shift was not successful. 

16. Electrical schematic in manuals- all electrical schematic’s are located in the CFI manual for the customer to reference  

17. Warranty forms for activation- before any warranty claim will be considered, the warranty claim activation form that is furnished in your CFI manuals will need to be signed and returned to CFI to be on file 

Spartan ERV Manuals- it is recommended that the customer read through the CFI manuals thoroughly upon delivery of any apparatus
