TROUBLESHOOTING

Most treadmill problems can be solved by following the steps below. Find the symptom that applies, and
follow the steps listed. If further assistance is needed, please see the front cover of this manual.

PROBLEM: The power does not turn on

SOLUTION:

a. Make sure that the power cord is plugged into a surge suppressor, and that the surge suppressor

is plugged into a properly grounded outlet (see page 10). Use only a single-outlet surge suppres-
sor that meets all of the specifications described on page 10. Important: The treadmill is not com-
patible with GFCI-equipped outlets.   

b. After the power cord has been plugged in, make sure that the key is fully inserted into the console.

c. Check the reset/off circuit breaker located on the

treadmill near the power cord. If the switch protrudes
as shown, the circuit breaker has tripped. To reset
the circuit breaker, wait for five minutes and then
press the switch back in. 

PROBLEM: The power turns off during use

SOLUTION:

a. Check the reset/off circuit breaker located on the treadmill frame near the power cord (see c.

above). If the circuit breaker has tripped, wait for five minutes and then press the switch back in.

b. Make sure that the power cord is plugged in. If the power cord is plugged in, unplug it, wait for

five minutes, and then plug it back in.

c. Remove the key from the console. Reinsert the key into the console. 

d. If the treadmill still will not run, see the front cover of this manual.

Remove the hood from the treadmill. Locate the Reed

tween the Magnet and the Reed Switch is about
1/8”.

If necessary, loosen the Screw (62), move the

Reed Switch slightly, and then retighten the Screw.
Reattach the hood, and run the treadmill for a few
minutes to check for a correct speed reading.
