CAUTION
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 thread on the front end of the motor and the rear of the Spindle, and turn the Spindle clockwise. If the
drive shaft of the motor does not engage properly to the drive dog on the Spindle, it may only turn aprroximately
two threads before stopping. DO NOT FORCE THEM TOGETHER. Loosen the Spindle from the motor, rotate the
Spindle shaft by hand then re-try. The drive shaft and the drive dog must be fully engaged. When fully engaged,
secure the motor and Spindle using the provided 27mm wrench (Fig. 2).
