Lower Board Replacement

Tools required:

Philips head screwdriver

Procedure:

1.  Turn off the power to the treadmill and unplug the power cord from the wall outlet.

2.  With a Philips head screwdriver, remove the motor cover.

3.  Verify that LED MTR is not lit on the lower board. If this LED is lit, please wait

approximately 1 minute until the light is out. This is an indication that the stored
power has left the board.

4. Unplug all the wires and cables from the lower board

(It is a good idea to note the position of all wiring before removing.)

5. With a Philips head screwdriver, remove the lower board, and replace it with a new

one.

Reconnect all the wires to the lower board.

Please refer to lower control board

wiring diagram.

7. Install the motor cover.

Re-plug the power cord, and turn power on.
