Intake System Cleaning
Caution: Take extreme care when performing this process. Failure to follow the
precautions and instructions may result in engine failure. Always wear proper
eye and skin protection when operating and maintaining this equipment.
1. Verify that ESX tank level is at least at the 1/4 full mark and that there are 8 oz of RTI FUEL
SYSTEM CLEANER to every 1/4 tank.
2. Connect red (positive) clamp on power cable to red (positive) terminal on vehicle battery.
Connect the black (negative) clamp to a ground on vehicle frame as far from the battery as
possible. All LED’s on keypad should illuminate for one second and buzzer should pulse. If
not, check connections and make sure REVERSE POLARITY LED is not illuminated. If
REVERSE POLARITY LED is illuminated reverse the battery connections.
3. Warm up vehicle to operating temperature.
4. Shut off vehicle and disconnect air cleaner or air inlet hose.
5. Turn the Pressure Control regulator on the control panel fully counterclockwise.
6. Connect ESX intake cleaner gun to the Red Hose on the ESX.
7. Hold down the Start button on the ESX control panel while simultaneously turning the
Pressure Control regulator closed or clockwise until the ESX System Pressure gauge reads
120 psi (the operator can adjust the regulator to achieve a more desirable spray pattern).
Release the Start button.
8. Take a shop rag and place it over the spray nozzle of the intake cleaner gun and hold the
push button trigger down for 3-5 seconds to purge all air out of the system. This allows the
intake cleaner gun to operate correctly.
9. Start the vehicle.
10. Spray air intake, choke plate, air horn, etc. with a generous amount of cleaner mixture. If
the engine starts to stutter or stall, discontinue spraying for 3-5 seconds or until the engine
idle resumes. Continue cleaning as long as necessary.
11. Once cleaning is complete, turn the engine off and reinstall air cleaner or air inlet hose.
12. Press the Stop button on the ESX control panel. After automatic purge, hold down the
manual Fill/Purge button and then depress the push button trigger on the intake cleaning
gun. This will drain all fluid from the intake cleaning gun.
13. Disconnect intake cleaning gun and return to appropriate setup procedure.
