If the armature for either the clutch or the
brake is too far away from its mating friction
surface, it is possible to move this back into
adjustment using a flat head screwdriver.
This is a three-step process.
1. Simply slide the screwdriver through the
window and press the armature toward its
mating friction surface.
2. Rotate the output of the unit. The rotor
and window should stay in place when you
do this. Only the armatures will move.
Rotating the rotor will move the window.
3. Repeat steps 1 & 2 to ensure that the air-
gap between the armature and its mating
friction surface is about 1/32" and that the
armature is kept square. (If the armature is
cocked, it may engage on one rim, giving
the appearance of engagement but failing
to provide full torque.)
If a scraping sound is noted when the output
shaft is spun, it means an armature is drag-
ging. Insert a screwdriver through the vent
holes and slot in the fan and pry the dragging
armature (clutch or brake as observed) away
from the mating surface evenly all the way
around. Re-check the engagement as
described in step B of the Start-Up instruc-
tions.
