. TROUBLESHOOTING
Make sure your hands and all interlocking parts of the spindle and motor are clean before
connecting the motor to the spindle. This is critical in preventing contaminants from entering
the motor or spindle.
Align the threads on the front end of the motor and the rear end of the spindle, then rotate the spindle clockwise. If
the drive shaft of the motor does not engage the drive dog on the spindle, it will not be possible for the spindle to
rotate. DO NOT FORCE THIS CONNECTION. Turn the spindle back a few threads, rotate the collet cap or spindle
shaft slightly by hand until the drive shaft and the drive dog are fully engages. This may take several attempts.
Use the 36mm wrench that have been provided for the final tightening of the spindle to the motor.
