Service manual

Replacing the Transformer
1. Turn off the treadmill circuit breaker and remove the power
cord from the power outlet.
2. Remove hood as previously described.
To prevent high voltage electrical shock: Before working on or around any
electrical or mechanical component under the hood, wait at least two
minutes from the time you unplug the power cord and be sure the red LEDs
on the VSD board are off.
3. Unplug the transformer wires from the VSD board. Note the
wire colors and connection points. Cut the plastic cable ties
that secure the transformer wiring.
4. Remove the Phillips-head screws that hold the transformer to
the headframe.
5. Discard the old transformer. Replace with new one in reverse
order.
A Wire routing depends upon the transformer you are installing
(see figures above).
6. Replace the hood assembly as previously described.
Field Functional Test
To verify that the treadmill is operating properly, perform Field
