CHAPTER 3: Troubleshooting
3.3.2 TROUBLESHOOTING – NO FUNCTION FOR SAFETY KEY
SOLUTION:
a. Check if the safety key is totally inserted into the console.
-If not, remove and insert again.
b
.Check if the safety key is oxidized or its condition does not affect its function.
-If yes , try cleaning it or replace it.
c. If the safety key is functional, check the safety key sensor wires in console.
-Suggest to re-connect the wires or to change new wires.
All manuals and user guides at all-guides.com

18
CHAPTER 3: Troubleshooting
3.3.3 TROUBLESHOOTING – NO RESPONSE FOR MACHINE (CONSOLE&MOTOR)
SOLUTION:
a. Check if the console beeps when all keys are pressed. If no, replace the keypads.
b. Enter Engineering Mode, and scroll to ENG 1 (Hardware Test).Press the key “ENTER” first and then
the key ”START”.
-When press the key “SPEED + / -“, if the data on windows “TIME” & “DISTANCE” is changed, the
console is ok. If not, replace the PCB.
c. Turn off the power switch, and open the motor upper cover. Remove the red & black wires of motor
from the MCB, and use a multi-meter to measure the resistance of drive motor.
If the resistance is bigger than 10 Ω, the drive motor is defective. Replace the drive motor.
If the resistance is lower than 10 Ω, the drive motor is ok. Then,
- Check the connection of the speed sensor (encoder disk group) at the MCB.
- Remove the speed sensor from the motor and clean it, then re-test.
- If the speed sensor is clean and has a good connection but still will not operate, replace the speed
sensor.
- Replace the MCB as the last step if machine does still not run after to take above actions.

CHAPTER 3: Troubleshooting
3.3.4 TROUBLESHOOTING - INCLINE MOTOR ISSUES
SOLUTION:
a. Press the "INCLINE" keys, the console should beep and display incline change, if no, replace the
key pad.
b. Enter Engineering Mode, and scroll to ENG 1 (Hardware Test). Press the “ENTER” key
first and then the “START” key.
c. Press the “INCLINE ▲/▼” key.
If can hear clicks from two relays at the MCB, the MCB is ok. Then check the connection of the
elevation motor at the MCB first, try to unplug and re-plug. If this does not resolve the issue,
replace the elevation motor.
If there are no clicks from these two relays, MCB is defective and replace the MCB.

CHAPTER 3: Troubleshooting
3.3.5 TROUBLESHOOTING - NOISE ISSUES
SOLUTION:
1. Thumping noise twice per rotation on new machine.
Sol. This noise is from the roller or running belt.
-If this is a new unit, some noise is normal as the running belt forms around the rollers.
-Check that the belt is centered and tensioned correctly.
-Remove and clean the rollers if needed.
-Replace the rollers or running belt as needed.
2. High pitched “bell-like” sound from under the motor cover.
Sol. This sound is likely a moving component.
-Remove the motor cover and check the drive belt for alignment and make sure it is not slipping or is
frayed / cut in any way. Replace the drive belt if needed.
-Make sure the optic disk on the motor is not rubbing the speed sensor.
-Turn the motor by hand to see if motor brushes or bearings are rubbing. Replace the motor
if needed.
-Check the front and rear rollers, replace if needed.
3. Rubbing / grinding noise.
Sol.. This sound is likely caused by the optic disk.
-Check that the optic disk is tight on the motor and not rubbing the speed sensor.
4. Banging or clunking sound/5. Slapping / thunking / squeaking sound with each footstep.
Sol. The sound is likely due to the unit not being level.
-Check that all levelers are touching the ground.
-Move the treadmill to another flat surface.
-This sound is from the running deck / belt.
-Check that the running deck is tightly attached to the frame.
-Check the deck shocks for denigration or crumbling. Replace if needed.
-Check to see if the air shock is making this noise, lubricate or replace if needed.
5. Rubbing sound underneath the treadmill.
Sol. This sound is likely due to the air shock.
-Lubricate or replace the air shock as needed.
6. Squeaking / grinding noise when using elevation.
Sol. This sound is likely from the incline motor.
-Check that the incline motor connection points include Teflon washers.
-Lubricate the incline motor worm screw and connection points with grease.
-Replace the incline motor.
