The following checklistwill ensure that the ATX-3 PLUS BOOST will run at peak efficiency and present an image to your customers that yourshop performs high tech transmission 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 transmission fluid and dirt off thecabinet.3. Do not allow the unit to sit outside in direct sunlight or inclement weather. Excessive exposure to sunlight ormoisture will cause serious damage and will void the warranty.4. The ATX-3 PLUS BOOST is not intended for mobile use where the unit is transported to customer sites.Excessive vibration will shorten component life, affect accuracy of performance and void the warranty. If theATX-3 PLUS BOOST needs to be transported by vehicle, remove all fluid, in both the new and used tanks, priorto transport.5. Be gentle when moving the ATX-3 PLUS BOOST around the shop. Tip the unit and ease the front casters overany obstacles such as door jams, air hoses and floor irregularities.6. Periodically check all internal (by lifting out the tool tray) and external hoses for leaks or excessive wear. Anyweak hoses should be replaced immediately to avoid possible injury.7. Check the four filter screens (Item 4 and 5 on Page 18) often to avoid any blockage that may occur. Clean outdebris or replace the filter screen if necessary.TROUBLESHOOTINGIf in Dipstick Mode and the READY light is on and the ATX-3 PLUS BOOST is unresponsive to a button beingpressed to initiate a process, do the following:1. Press COOLER MODE.2. Press DRAIN PAN.3. Press STOP after pressure on gauge reaches 0 PSI or after 3-4 seconds.The READY light should go off. If not, repeat above steps a second time.If the new fluid tank is full and Add New Fluid light is flashing while selecting an exchange service, lower the volumeof new transmission fluid to 25 liters, using EMPTY NEW FLUID feature.Calibration - A Good PracticeThe ATX-3 PLUS BOOST is the most accurate of all transmission fluid exchangeequipment due to the advanced load cell technology designed into the unit.Most operating problems are usually fixed by performing a simple calibrationprocedure.A good practice is to periodically calibrate the ATX-3 PLUS BOOST to ensureoptimum performance.The following pages describe the reasons for calibration and the actualcalibration procedure.
