  2. Place a rule on the outer edge of the pulley. Use a depth gauge to measure up to the pressure plate. Apply battery voltage to the magnetic clutch and measure the distance (air gap) to the attracted pressure plate. Always measure at least three points on the pressure plate in order to obtain a mean value. Distance: 0.5 mm ± 0.15 mm
  3. If the air gap is not in the tolerance range, it must be adjusted using spacers -B-  .
