MAINTENANCE
The ESX will provide many years of reliable service if properly maintained. The following checklist
will ensure that the ESX will run at peak efficiency and present an image to your customers that
your shop performs high tech fuel system cleaning services.
1. Use tool tray for storage of tools and adapters only.
2. Keep the exterior surface clean. Use a mild all purpose cleaner to wipe fuel and dirt off the
cabinet.
3. Do not allow the unit to sit outside in direct sunlight or inclement weather. Excessive exposure
to sunlight or moisture will cause serious damage and will void the warranty.
4. Periodically check all internal (by lifting out the tool tray) and external hoses for leaks or
excessive wear. Any weak hoses should be replaced immediately to avoid possible injury.
5. Check air pressure in rear tires periodically (should be 30 psi), add air if needed.
ESX fuel filter removal and replacement:
The ESX Fuel Filter should be replaced every 30 cleaning cycles. Follow the steps listed below
for a safe and proper filter change.
1. Turn the ESX Pressure Regulator clockwise until it is completely closed.

Connect black (negative) clamp to a ground on vehicle frame as far from battery as possible.
3. Connect any fitting adapter to the ESX Red Hose and place opened end into an appropriate
container.
4. Press and hold the Start button on the ESX keypad until the fuel from the ESX fuel tank has
been emptied into the storage container.

6. Dispose of or store fuel within local and federally approved methods.
