1. Wipe down shaft and motor's
rotor hub bore. Light oil
residue is acceptable, but
remove grease and other
contaminates.
2. Slide motor onto the shaft.
Install four (4) mounting bolts
(customer supplied). Tighten
bolts in an alternating pattern
to fully secure motor to
machine frame.

1. Remove the Black Phillips
Screw from the hole labeled
"A" to access the compres-
sion coupling.
1. Insert a hex bit attached to a
torque wrench into the hole
labeled "A" and tighten the
compression coupling:
C04x: Use a 5 mm hex bit
and torque to 12.4 N-m [110
lb-in].
C05x & C06x: Use a 6 mm
hex bit and torque to 30 N-m
[264 lb-in].
Failure to properly torque
the compression coupling
can allow the shaft to slip in
the hub. This relative mo-
tion can generate enough
heat to permanently weld
the hub and shaft together!
