How To Adjust The Running Belt Tracking

Tools Required: Allen key set. (All fasteners are metric. Make sure that you have metric tools.)

1. After the treadmill has been installed and leveled, the belt must be checked for confirm proper tracking. First, plug the power cord into an appropriate outlet and turn the treadmill ON.
2. Press the QUICK START button then increase speed to 18.0kph motor speed using the UP arrow.
3. Tighten the running belt by turning the running belt tension bolts before adjusting the belt alignment.
If the running belt has moved to the RIGHT, turn the RIGHT tension bolt 1/4 turn CLOCKWISE and the left tension bolt (A) 1/4 turn counterclockwise to start the running belt tracking back to the center of the rear roller.
If the running belt has moved to the LEFT, turn the LEFT tension bolt (A) 1/4 turn
CLOCKWISE and the right tension bolt 1/4 turn counterclockwise to start the running belt tracking back to the center of the rear roller.
4. Repeat this adjustment until the running belt appears centered. The belt should be equal distance (B) on both sides of the rear roller.
5. Allow the unit to operate for several minutes to see that the belt remains centered.
NOTE: During the adjustment above, DO NOT exceed one full turn of the adjusting screws in either direction.

How To How To Adjust The Running Belt Tension

Tools Required: Allen key set. (All fasteners are metric. Make sure that you have metric tools.)

1. Locate the two BELT TENSIONING BOLTS on each side of the REAR ROLLER MOUNTING BRACKETS. The TENSIONING BOLTS are accessible from the holes provided in the REAR ROLLER GUARDS.
2. Enter the manual program and adjust the belt alignment by operating at 8.0kph for five minutes. DO NOT run on the belt.
3. Enter the speed up to 18kph and check if the belt centers the treadmill.
4. Using the speed DOWN button  to slow down to 1kph. With the RUNNING BELT speed at 2 kph (3.2 kph), begin walking on the treadmill. Tightly grasp the HANDLEBARS and attempt to stall the RUNNING BELT. If it slips, repeat step 4. If it does not slip, the tension is correct.
5. Stop the treadmill and alternately turn the RUNNING BELT TENSION BOLTS (A) 1/4 turn clockwise to tension (See Tracking (Centering) an Existing or New Running Belt on previous page). Repeat step 3 and step 4 until slipping is eliminated. DO NOT EXCEED ONE FULL TURN.

Incline motor calibration

When incline motor needs calibration:

1. When controller is changed.
2. When incline motor is changed.
3. When both controller and incline motor are changed.
4. When controller CPU is changed.
CALIBRATION
1. To calibrate, make sure the treadmill is not running (running belt not moving).
2. Turn power on. Wait for a few seconds.
3. Press the STOP and SPEED- buttons at the same time, then both STOP and SPEED+, and then SPEED-. Now the treadmill is in calibration mode.
Press the START button. The treadmill will run calibration the incline motor.
4. Run through a few functions to make sure everything is in good condition.

ERROR CODE CAUSES AND SOLUTION

Err3
Safety tether key error
a. Safety tether key not inserted.
b. Human factor – e.g.
Something may be put inside the console.
c. Safety key micro switch defect.
d. Safety key micro switch terminal inside console looses.
Err5
Incline motor error.
a. Time delay problem.
b. Incline motor sensor cable has problem.
c. VR of the incline motor sensor is defective.
d. Incline motor is damaged.
e. The incline motor is over-loaded or over-heated.
1. Do calibration.
2. Check all wire connections.
3. Replace incline motor.
4. Replace controller.
d. Replace incline motor.
e. Eliminate human factors.

Err6
Internal memory error.
Console is not able to write and read the internal memory.
Turn off and on again to clear Error 6.

Err10, Err11
Communication error
The motor controller and console lose connection. It will happen if the signal cable is loose.
Insert the signal cable again.
If it will happen, replace the signal cable.

Err20
Over current error.
Abnormally high current flows to the motor controller.
Cool the motor and motor controller for around 30 minutes and check the deck and belt lubrication.

Err21
Over heat error.
The motor controller is over heated.
Cool the treadmill more than 1 hour and try again. Check the deck and belt lubrication.

Err22
High input voltage.
The AC input voltage is too high to operate the treadmill normally.
Check the AC input voltage.

Err23
Low input voltage.
The AC input voltage is too low to operate the treadmill normally.
Check the AC input voltage.
