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 call the toll-free telephone number on 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 frame 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 the

drawing 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 fully into the console.

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

PROBLEM: The displays of the console do not function properly

SOLUTION: a. Remove the key from the console and UNPLUG THE

POWER CORD. Remove the Screws (2) from the

Hood (1), and carefully pivot the Hood off.

Locate the Reed Switch (10) and the Magnet (18) on

the left side of the Pulley (17). Turn the Pulley until

the Magnet is aligned with the Reed Switch. Make

sure that the gap between the Magnet and the

Reed Switch is about 1/8”. If necessary, loosen the

Screw (26), move the Reed Switch slightly, and then

retighten the Screw. Re-attach the Hood, and run the

treadmill for a few minutes to check for a correct

speed reading.
