3. Disconnect the wire connector on the drive board on the AC Drive 

Module.

4. Follow the procedure to remove the grade motor chain (see 

“Replacing the Grade Motor Chain” on page 4-13).

5. Remove the four 7/16 in. hex head bolts that attach the grade motor to 

the headframe, then remove the motor.

6. Install a new grade motor, following steps 3-4 in reverse. Use a 

straight edge to align the motor sprocket with the pinion shaft chain 

sprocket.

7. Restore power to the treadmill and test the new grade motor.

Warning!

High voltage is present when the treadmill is plugged into 

a power source. Secure loose hair, clothing, and jewelry 

before working near rotating machinery.

Verify that:

a. the treadmill operates over the full range of 0-15% grade.

b. there is no binding when it moves up or down.

c. the chain is aligned correctly. A popping sound in the chain 

indicates that it is misaligned.

8. If no other service is required, replace the treadmill hood as described 

in step 10, page 4-5.
