3. Tighten or loosen the adjusting nut as needed to
achieve the 0.4 mm (0.015 in.) air gap. Perform this
operation at all 3 inspection windows.
(A) Electric clutch
(Q) Adjustment nut
This adjustment should be done every 500 hours of
operation or annually, whichever comes first. In
case the machine is heavily used, air gap settings
should be checked more often.
If the air gap is too narrow, the clutch armature may
drag when disengaged, resulting in premature
failure.
