NOTICE:

This document provides instructions for the replacement of the Motor Mount on the Nautilus

™

T618 Treadmill.

If you need assistance, please call Nautilus Customer Service at 1-800-605-3369.

1. Unplug the power cord from the machine and wait 5 minutes. Place the

power cord in a secure location.

2. Using a #2 Phillips screwdriver remove the 4 indicated screws and two

additional screws from the Motor Cover. Lift and remove the Motor Cover.

3. Be sure to observe the distance from the Speed Sensor to the Drive

Pulley. This distance affects the performance of the Speed Sensor, and

can easily be shifted accidentally during replacement procedures.

4. Using a #2 Phillips screwdriver, disconnect the Motor Ground Wire from

the Frame.

5. Using a 6mm hex wrench, loosen the indicated screws on the Motor

Mount.

6. Using a 13mm Open Ended Wrench, rotate the Belt Tensioner Screw

enough to loosen the Drive Belt.

Note:

To assist with reassembly, be sure to record the number of threads

exposed before loosening.

7. Using a 6mm hex wrench, remove the indicated screws from the Motor

Mount. Remove the Drive Belt and rotate the Motor Assembly exposing

the Motor Mount.

To reduce the risk of electrical shock or unsupervised usage of the equipment, always unplug the power cord from the

wall outlet and wait 5 minutes before cleaning, maintaining or repairing this machine. Place the power cord in a secure

location.
