Hold the edge of the rotor of the fan motor by using a pair of groove joint pliers. CAUTION: • Make sure that any pieces do not enter the gap between the rotor and the stator of the fan motor. Because the rotor is easy to be shaven by pliers and metal pieces may be produced. • Do not touch the pliers to the coil of the fan motor because the coil may be cut or injured. • Do not disfigure the bracket by touching with the pliers. 9. Remove the fan blade assembly from the shaft of the fan motor by pulling and rotating the fan blade with your hand. 10.Now, the fan blade will be free. CAUTION: • Do not re-use the removed fan blade because the hole (for shaft) may be larger than normal.

Install the fan motor to the fan duct with the two (2) screws. 2. Install the fan blade to the fan motor shaft according to the following procedure. 3. Hold the center of the bracket which supports the shaft of the fan motor on the flat table. 4. Apply the screw lock tight into the hole (for shaft) of the fan blade. 5. Install the fan blade to the shaft of fan motor by pushing the fan blade with a small, light weight, ball peen hammer or rubber mallet. CAUTION: • Do not hit the fan blade strongly when installed because the bracket may be transformed. • Make sure that the fan blade rotates smooth after installed. • Make sure that the axis of the shaft is not slanted. 6.
