Installation Instructions

1. Put the machine flat on the ground., then fold up the column and stabilize it;(Be careful not to pinch your hands at the fold at the lower end!)
2. Use the knob to lock the column (lock while slightly shaking the column, to better lock) as shown in the figure; When the knob locks the column, if you feel that the column has a slight shake, you can use the 5# Allen wrench to lock it again.
3. The armrest tube is folded down as shown in Figure 1; the electronic watch is folded up as shown in Figure 2;

Using two levels of manual incline:
Fold the left and right incline metal counterclockwise, and then adjust the middle adjustment foot pad until it touches the ground (if there is a gap between the rear end adjustment foot pad and the ground, adjust it to contact the ground first).

How to adjust the machine table to be flush with the ground:
When there is a gap between the machine table and the ground (or when it is adjusted in two stages), it is necessary to adjust the adjustment foot pad at the rear end of the machine table so that the front and rear Both are in contact with the ground, and then adjust the middle adjustment foot until it is in contact with the ground.

Note:
Adjusting the gap between the foot pad and the ground will cause the machine and console to shake!)

Please note that after confirming that all installations have been completed according to the above requirements, it is necessary to lock them uniformly and check that there are no omissions before connecting to the power supply.

Machine folding:
When you are not using it, first loosen the knob at the lower end of the column (counterclockwise direction) as shown in Figure A; Then fold the Electric watch to position B as shown in the figure; Turn out the knob anticlockwise until the armrest tube can move anticlockwise, and then fold the Electric watch onto the running platform.

Machine expanding:
When it is necessary to expand the running table, first move the column to the fixing hole in the counterclockwise direction as shown in Figure C, and then use the knob to lock the column (lock the column slightly while shaking it for better locking). If the knob locks the column slightly, you can use the 5# Allen wrench to lock it again; Then fold the handrail tube down to the position as shown in Figure D, lock it with the plum knob (clockwise), and fold the electronic watch up to the position as shown in Figure D (clockwise).

Translation of Error Codes

Fault code

| Failure Description|

Fault handling

---|---|---

E1

| Communication Abnormal: when the power is on, the connection between the lower controller and the console is abnormal.| Possible Cause: the communication between the lower controller and console is blocked, check each joint between the controller and console, and ensure that each core is fully plugged in. Check the the connection line, and replace it if it’s damaged.
E2| No signal from the motor.| Possible Cause:

Check the motor cable to see whether it is connected well or not, if not, connect the motor wire again.

Check the motor cable to see whether it is damaged or has a burnt smell, if yes, replace the motor.

Check the speed sensor to see whether it is correctly installed or

damaged

---|---|---

E5

| Over current protection:

In working, the lower controller detects the current to be over 6A for more than 3 seconds.

| Possible Cause:

Overloading leads to excessive current, and the system stops out of self- protection, or some part is stuck, causing the motor to stop. Adjust the treadmill and restart it. Check if there is a liquid or burnt smell while the motor is running, if yes, replace the motor; check if the controller has a burned smell, if yes, replace the controller; check the power supply voltage, if it does not match the specifications, change into correct voltage and test the machine again.

E6| Explosion-proof impact protection: the abnormal voltage or motor causes the faulty circuit that drives the motor.| Possible Cause:

Check if the power supply voltage is 50% lower than normal voltage, use the correct voltage and test the machine again; check if the controller has a burnt smell and replace the controller; Check if the motor cable is connected and connect the motor wire again.

E7| No safety key| Put the safety key in the right place.

Routine maintenance

• Warning: Before cleaning or maintaining products, please be sure the power plug of the treadmill is pulled out.

• Cleaning: Comprehensive cleaning will extend the use life of the electric treadmill.
  Remove dust periodically to keep the parts clean. Be sure to clean the running belt with both sides of the exposed portion, which will reduce the accumulation of impurities. Make sure to wear clean athletic shoes to avoid carrying dirty matters into the running board and belt. Treadmill belts shall be cleaned with a damp cloth with soap. And please pay attention to avoid wetting the electrical components and running belt.

• Warning: Make sure the power plug is disconnected before moving the motor cover away, and clean the motor at least once a year.

Running Belt Alignment
Put the treadmill flat on the ground. Make the treadmill run at a speed of 3-4 miles/hour.

• If the running belt is closer to the left: rotate the left adjusting bolt with 1/2 turn clockwise, then rotate the right adjusting bolt with 1/2 turn counter-clockwise. (Picture A)
• If the running belt is closer to the right: rotate the right adjusting bolt with 1/2 turn clockwise, then rotate the left adjusting bolt with 1/2 turn counter-clockwise. (Picture B)

Running Belt Tension Adjusting
When you use the treadmill for a long time, the running belt or the multi- wedge belt becomes loose because of the abrasion. To facilitate safe use, an appropriate adjustment is needed.

Judgment:
The feeling of running with the occasional pause phenomenon indicates that the treadmill belt or multi-wedge belt is a little loose and further affirmation needs to be made.

• Step 1: Remove the motor cover, make the treadmill run at a speed of 0.5 miles/h, and then stand on the running belt, hold the handlebar, and tread the treadmill belt slightly.
  • The instantaneous step can not stop the belt, the tightness is appropriate.
  • If your instantaneous step stops the running belt, but the multi-wedge belt and front roller are still running, it indicates that the running belt is loose and appropriate adjustments must be made to facilitate the safe use.
  • If you observe that the instantaneous step makes the treadmill belt and multi-wedge belt stop, but the motor is still running, it indicates that the multi-wedge belt is loose and appropriate adjustments must be made to facilitate the safe use.
• Step 2: Use a wrench to adjust the screws on the motor base according to the condition. Meanwhile, gently flip the multi-wedge belt between the motor shaft and the front roller, if it is too loose, you can flip the multi-wedge belt by 100%; if it is too tight, the degree to flip the belt is very limited. It is appropriate to flip the multi-wedge belt by 80% after adjustment. Please adjust the tightness of the multi-wedge belt to the state that it could be flipped by 80%.
• Step 3: Finally lock the motor base, and install the motor cover.

Lubrication of Running Belt

• The friction between the running belt and the running board has a significant impact on the service life and performance of the electric treadmill.
• Lightweight users (using<3 hours per week) once every 10 months; Heavyweight users (using>7 hours per week) once every 5 months.

Method of adding lubricating oil:

• Step 1: Open up the treadmill belt.
• Step 2: Open the silicone oil bottle, and squeeze the silicone oil on the side of the running board, as shown in the following picture:

Treadmills belong to sports equipment and therefore require appropriate maintenance. Maintenance Recommendations are as follows:

1. Due to wear and damage, regular inspections are required; After maintenance or professional repair for the worn or damaged accessories (such as motors, electronic controls, power cords, etc.), its safety level must be consistent with that of the factory.
2. Immediately replace those defective components or idle the equipment for repair(such as power cords).
3. Pay special attention to the components that are most prone to wear and tear. (such as a running belt)
