Copes Quick Change
Aerobell Motor Removal
1. Prior to removing the Quick Change Motor
Assembly, flush the paint feed line and bell
with solvent. If flushing is not possible and
paint is in the atomizer feed tube, place a rag
over the bell end of the atomizer and proceed
to step 2.
2. Using 75852-00, retaining nut tool, loosen
75844-00, quick change motor assembly
retaining nut. Loosen retaining nut CCW to
complete thread disengagement.
3. While properly supporting the quick change
motor assembly, remove from the manifold.
Do not allow any paint to drip from the
manifold into the air ports on the back of the
air turbine.
4. Reinstall 76756-00, shaping air ring, into
shroud. Note that when screwing 76756-00 in
place, it will become tight after approximately
2-1/2 turns. At this point, use a strap wrench
if required, to tighten further. The 76756-00
will break free and become loose again and
can then be tightened down fully by hand
until it bottoms against the shroud.
5. Screw 76757-00, shaping air ring cap,
onto the 76756-00, shaping air ring, in CW
direction. Hand tighten until the ring and
cap mating tapered surfaces contact and
hand torque 1/8 turn.
