    • Operating range 170-195
    • High alarm at 205
    • Red alarm with buzzer
  5. Voltmeter
    • Indicates charging or not charging
    • Normal range 13.8-14.2
    • Always high idle when not pumping
  6. Front and Rear Air Brake
    • Operating range 90-120 psi
    • Low alarm at 60 psi

  9. Jake Brake
    8, 4, and off (high, low , off)
  10. Hi/Low Voltage indicator
    • Green=Normal
    • Low=Low volt (ECM will go high idle if not pumping)
    • High=High volt (turn off electrical and go OS)
  11. Retieving Trouble Codes
    • DDEC for CEL or SEL codes: code, pause, code
    • ATEC for Check Transmission codes (don't turn off or go R) then restart to possibly clear.

    • 3" Discharge Line
  17. Booster tank capacity
    500 GPM
  18. Intake Relief Valves (Dump Valves)
    • 3 intakes each with valves
    • Valve set at 90 psi
    • Helps maintain 50 psi net pressure differential for relief valve
  19. Donaldson service indicator
    • Air filter indicator
    • Red is clogged
    • Start engine and press to clear (green) or call mechanic
  20. High Idle Switch interlocks (3)
    • Parking Brake
    • Transmission in Neutral
    • Pump not in gear
  21. Transmission High Temp fix
    • Warning at 250 F
    • Stop
    • Neutral
    • RPM 1200-1500, 1-3 min
    • If temp drops continue, if not shut down
  22. Battery Charger
    • Slow blink is fully charged battery
    • Flicker when close
    • Bright and alternating when charging
  23. Cab Tilt
    • Closed system (no fluid checks)
    • Pneumatic assist
    • Manual (behind driver's seat is handle)
    • Cab seal toggle to OFF
    • Pump lever toward front to "raise" position
    • "Lower" to rear of cab and leave in this position as lock
    • Cab seal to ON and leave in this position (wired to battery)
  24. Ladder Rack
    • Closed system (no fluid checks)
    • Battery on to opperate
    • Interlocked with two upper compartment doors
    • Ladder rack alarm sounds if e-brake released
  25. Dipsticks
    • Oil Forward (1 gallon Low to High)
    • Check with mechanics for oil weight
    • Transmission Rear
  26. Ways to fill the air system (4)
    • 1. Engine through compressor
    • 2. External air- valve between reserve canister and petcock
    • 3. External air - cab tilt aux inlet
    • 4. External air at pump panel inlet
  27. Vernier throttle interlocks
    • Parking Brake on
    • Transmission in N
    • Must have been fully "OFF" (clockwise) before put in pump gear.
  28. 5 intakes
    • 1. Front suction (butterfly valve)
    • 2. Two PIVs (piston valve)
    • 3. Two passenger side aux intakes (ball valves)
  29. Relief Valve optimal net pump pressure
    50 PSI

    ex: Pump Flowing at 140 PSI with 90 PSI hydrant
