5. For air option model Atd-7431 Series A, pour a teaspoon of good quality, air tool lubricant into the air supply inlet
of the lift control valve. Connect to air supply and operate for 3 seconds to evenly distribute lubricant.
Note: This unit is equipped with the popular 1/4” NPT air coupler. When installing a different air coupler of your
