Troubleshooting and error codes

Problem	Cause and Solution
The power does not turn on	Ensure the power cord is correctly plugged into a surge suppressor and grounded outlet. Use a UL 1449 TVSS surge suppressor (120V AC, 15 amps). Verify the key is fully inserted into the console. Check the circuit breaker on the treadmill; reset if tripped (wait 5 mins). Confirm the on/off switch is in the 'on' position.
The power turns off during use	Check and reset the circuit breaker if tripped (wait 5 mins). Ensure the power cord is securely plugged in. Reinsert the key fully into the console. Check that the on/off switch is in the 'on' position. If issue persists, call helpline.
Console displays do not function properly	Check the Reed Switch and Magnet alignment near the pulley under the hood. Gap should be ~1/8". Adjust Reed Switch position if needed.
Walking belt slows when walked on	Use a UL-listed surge protector (15 amps, 14-gauge cord, <5 feet). Loosen walking belt if overtightened by turning rear roller bolts counter-clockwise (1/4 turn each). Belt should lift 3-4 inches off platform. Keep belt centered. If issue persists, call helpline.
Walking belt is off-center	Belt shifted left: Turn left rear roller bolt clockwise, right bolt counter-clockwise (1/4 turn each). Belt shifted right: Turn left rear roller bolt counter-clockwise, right bolt clockwise (1/4 turn each). Keep belt centered and do not overtighten.
Walking belt slips when walked on	Tighten walking belt by turning both rear roller bolts clockwise (1/4 turn each). Belt should lift 3-4 inches off platform. Keep belt centered.
