  • Page 26 MAINTENANCE INSTRUCTIONS AND PARTS BOOK CERTIFIER 912 Congratulations on your purchase of the 912 Certification System. As you become familiar with the system be sure you learn to protect it to ensure a long life and eliminate repair costs. Make sure you have a planned maintenance schedule.
  • Page 27 Make sure that your input power always contains a ground pin. Note: a good AC earth ground is necessary for the 912 to have accurate 121 time data. Make sure that the AC electrical outlet is properly grounded and that the neutral ground reference point is not greater than 100 feet from the AC outlet.
  • Page 28 MAINTENANCE INSTRUCTIONS AND PARTS BOOK CERTIFIER 912 Make sure your input air is moisture free and no lubricants are added. This could cause the manifold’s internal components to not function properly. Air quality should be inspected regularly. Take the bottom cap off the regulator and make sure the filter is clean and dry (Filters may vary).
  • Page 29 If you suspect the sensor to be faulty, do not disassemble the product. Disassembly could loosen or break internal wires and cause permanent damage. The sensor’s status can be checked with the hub diagnostic tab on the GUI screen, or by calling Lite-Check for troubleshooting instructions.
  • Page 30 MAINTENANCE INSTRUCTIONS AND PARTS BOOK CERTIFIER 912 When testing is in progress, all cables should be placed in a safe path away from high traffic areas. This prevents the cable being run over and/or cut, causing wires to short and severely damaging electronic equipment inside the tester. Inspect the cables on a regular basis.
  • Page 31 CERTIFIER 912 MAINTENANCE INSTRUCTIONS AND PARTS BOOK The 4 contact pins in each hub sensor receptacle should be straight and equally spaced. Damaged pins making contact will cause costly damage to the hub’s circuitry. If the pins are broken, replace immediately.
  • Page 32 MAINTENANCE INSTRUCTIONS AND PARTS BOOK CERTIFIER 912 Air differential kits gathering data during tests are highly sensitive. The straight swivel in the manifold has a .0018 inche hole drilled through it. Any debris trapped in the manifold will affect the test results causing failures.
