Zeroing Vacuum Gauge

NOTE: To zero SEEDSTAR ™ monitor vacuum gauge, see your SEEDSTAR ™ operator's manual.

With vacuum pump system shut off and vacuum gauge in a vertical position, disconnect vacuum monitor line to vent gauge to atmosphere. Use the zero adjusting screw (A) to set the gauge pointer exactly on zero mark. Connect monitor line, activate vacuum pump hydraulics, fill seed-disk cells with seed by driving forward with planter lowered and adjust vacuum level to recommended setting.
