7. CONNECTION TO THE MOTOR

CAUTION
• Make sure that your hands and all interlocking
parts of the spindle and machine are clean before
connecting the spindle. This is critical to prevent
foreign matter from entering the spindle.
• Mount the spindle on the motor as straight as
possible to prevent the mating parts from seizing.
• Mount the spindle on the motor by using one
wrench on the flats of the spindle and another
wrench on the flats of the motor. Never attempt
to tighten the motor by holding the body of the
spindle or motor.
Align the threads on the front end of the motor and the rear end
of the spindle, and turn the spindle clockwise. If the drive shaft
of the motor does not engage the drive dog on the spindle, do
not attempt to forcibly tighten the spindle. Turn the spindle back
a few threads, turn the drive shaft of the motor to engage it with
the drive dog, and then tighten the spindle with the provided 24
mm wrench and the 27 mm wrench supplied with the motor.
