Running Belt and Deck Troubleshooting

This procedure is to be used to determine the condition of the running belt and running deck
combination.
A clamp-on ammeter will be used to measure the treadmill's
The AC input current is a direct indication of the load being placed on the treadmill. Treadmill
loading consists of several factors, the user's weight, treadmill speed and condition of the run-
ning belt and running deck.
The AC input current measurements should be performed at 7-8 mph. and 0% incline.
Because the loading varies with the user's weight, you should perform the AC input current
measurement test on a new running belt and deck combination. That will provide you with a
benchmark reading to account for your individual weight.
Because the AC input current reading will pulse between a high value (during foot plant) and a
low reading (between foot plants) we suggest the use of an analog clamp-on ammeter. An
analog ammeter makes it very easy to see the AC current pulses. The refresh rate on digital
ammeters may make it difficult to see the rapid current peaks unless the digital ammeter is
equipped with a peak hold feature.
Procedure
1. Remove the treadmill's motor cover and place the AC clamp-on ammeter on the brown
wire from the AC. input module (or AC. power cord) to the circuit breaker (ON/OFF
switch). See the illustration below.
2. Set the treadmill's speed at 7-8 mph and the incline at 0%. Walk on the treadmill and
observe the average AC. current reading. Typical average AC. current reading on a
