4. Observe the Readout/Controller display reading. The reading should be between 028.00 and 058.00 mils. · If the measurement is within tolerance, continue on to the next step. · If the reading is less than 028.00 mils, rotate the pivot adjuster until the Readout/Controller displays a reading of 030.00 mils. If the reading cannot be increased to 030.00 mils, the carriage rod needs adjustment. · If the reading is greater than 058.00 mils, rotate the pivot adjuster until the Readout/ Controller displays a reading of 056.00 mils. If the reading cannot be decreased to 056.00 mils, the carriage rod needs adjustment.
