Mount the Motor
Follow these steps to install a motor on the machine.
1. Insert the shaft key (provided) into the keyway of the machine shaft.
Position the point on the shaft key in the direction of the motor, and then
fully seat the key in the slot.
2. Verify the cardboard cover and protective paper sleeving are removed.
3. Slide the motor onto the shaft, and position the motor on the pilot extension
of the machine.
4. Rotate the motor on the machine shaft to align the mounting holes with
those on the machine.
5. Insert a fastener in each of the four (4) mounting holes in the motor
faceplate, and hand-tighten each fastener to secure the motor to the machine
frame.
6. Using an alternating pattern, tighten each fastener within the recommended
torque range.
IMPORTANT
When the shaft key is properly installed, it provides a rigid mechanical
connection with the potential to assist in the alignment of the motor.
