NOTE! Do Not remove retaining screws (9). Adjustment is carried out by using a 9/16 inch (14 mm) open end wrench and a 1/4 (6 mm) socket key).

1.Turn Allen head retaining screws (9) counterclockwise to loosen one at a time to allow adjustment of threaded spacers (7). 2.Using an 9/16 (14 mm) open end wrench, the brass nut on threaded spacers (7) can now be threaded in or out of magnet. This changes the relative position of armature and end plate, thus changing the air gap.

Turn the brass nut to the left (clockwise) to increase air gap. Turn the brass nut to the right (counter-clockwise) to decrease the air gap.

NOTE! Be sure to tighten Allen head retaining screw (9) before checking air gap. The gap should be checked on each side of the brass nut to assure consistency in the setting.

3.The air gap should be set to 0.008 inch to 0.014 inch (0.20 mm to 0.36 mm) and be within 0.003 inch (0.08 mm) throughout entire circumference.
