Troubleshooting

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

SYMPTOM: The power does not turn on

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 17). Use only a surge suppressor that meets all of the specifi cations described on page 17.
IMPORTANT: If the treadmill is connected to an AFCI-equipped outlet and your circuit breaker trips repeatedly when the treadmill is used, see the front cover of this manual to purchase an arc fi lter.
b. After the power cord has been plugged in, make sure that the key is inserted into the console.
c. Check the power switch located on the treadmill frame near the power cord. If the switch protrudes as shown, the switch has tripped. To reset the power switch, wait for fi ve minutes and then press the switch back in.

SYMPTOM: The power turns off during use

a. Check the power switch (see the drawing above). If the switch has tripped, wait for fi ve 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 fi ve minutes, and then plug it back in.
c. Remove the key from the console, and then reinsert it.
d. If the treadmill still will not run, please see the front cover of this manual.

SYMPTOM: The incline of the treadmill does not change correctly

a. Calibrate the incline system (see step 4 on page 26).

SYMPTOM: The treadmill will not connect to the wireless network

a. Make sure that the wireless settings on the console are correct (see page 27).
b. Make sure that the settings for your wireless network are correct.
c. If you still have questions, see the front cover of this manual.

SYMPTOM: The walking belt slows when walked on

a. Use only a surge suppressor that meets all of the specifi cations described on page 17.
b. If the walking belt is overtightened, treadmill performance may decrease and the walking belt may become damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller screws (A) counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
c. Your treadmill features a walking belt coated with high-performance lubricant.
IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform unless instructed to do so by an authorized service representative. Such substances may deteriorate the walking belt and cause excessive wear. If you suspect that the walking belt needs more lubricant, see the front cover of this manual.
d. If the walking belt still slows when walked on, see the front cover of this manual.

SYMPTOM: The walking belt is off-center or slips when walked on

a. If the walking belt is off-center, fi rst remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left idler roller screw clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller screw counterclockwise 1/2 of a turn. Be careful not to overtighten the walking belt. Then, plug in the power cord, insert the key, and walk on the treadmill for a few minutes. Repeat until the walking belt is centered.
b. If the walking belt slips when walked on, fi rst remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller screws clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

SYMPTOM: The displays of the console do not function properly

a. If the console does not boot up properly, or if the console freezes and does not respond, reset the console to the factory default settings. IMPORTANT: Doing this will erase all the custom settings you have made to the console. Resetting the console requires two people. First, press the power switch into the off position. Next, locate the small reset opening (B) on the back edge of the console. Using a bent paper clip (C), press and hold the reset button inside the opening, and have a second person press the power switch into the on position. Continue holding the reset button until the console turns on. When the reset operation is complete, the console will turn off and then turn back on. If it does not, use the power switch to turn the treadmill off and then on again. Once the console turns on, check for ﬁ rmware updates (see HOW TO USE THE MAINTENANCE SECTION on page 26).
Note: It may take a few minutes for the console to be ready for use.
