BELT ADJUSTMENT
The running belt is pre-adjusted to the running deck at the factory, but after prolonged use it can stretch and require readjustment. To adjust the belt, turn on the main power switch of the treadmill and let the belt run at a speed of 4-5 MPH. Use the Allen Wrench provided to turn the rear roller adjustment bolts in order to centre the belt. If the running belt is shifting to the left, turn the left adjustment bolt 1/4 turn clockwise, and the running belt should start to correct itself.

If the running belt is shifting to the right, then turn the right adjustment bolt 1/4 turn clockwise, and the belt should start to correct itself.
Keep turning the adjustment bolts until the running belt is properly centered.

If the running belt is slipping during use, turn off and unplug the treadmill. Using the Allen Wrench provided, turn both left and right rear roller adjustment bolts 1/4 turn clockwise, then turn the main power switch back on and run the treadmill at a speed of 4-5 MPH. Run on to the running belt to determine if the belt is still slipping. Repeat this procedure until the belt no longer slips.

CARE AND MAINTENANCE
⚠ WARNING: To prevent electrical shock, please turn off and unplug the treadmill before cleaning or performing routine maintenance.
WARNING: Always check the wear and tear components like spring knob and running belt to prevent injury.
LUBRICATION
Lubricating your treadmill running belt will ensure superior performance and extend its life expectancy. When you receive your treadmill please apply some lubricant into each oil cap. After the first 25 hours of use (or 2-3 months) apply some lubricant and repeat for every following 50 hours of use (or 5-8 months). Run on the treadmill at a slow speed for 3 to 5 minutes to evenly distribute lubricant.
How to check running belt for proper lubrication?
Remove the cap on the lubrication system, squeeze few drops of lubricant inside. If the surface is slick to the touch, then no further lubrication is required. If the surface is dry to the touch, apply some lubricant.
Avoid over oiling the running deck.

CLEANING
After each exercise, ensure that the unit is wiped down and any sweat is removed from the unit. The treadmill can be cleaned with a soft cloth and mild detergent. Do not use abrasives or solvents. Be careful not to get excessive moisture on the display panel as this might damage the unit and create an electrical hazard. Please keep the treadmill, especially the computer console, out of direct sunlight to prevent damage to the screen.
STORAGE
Store the treadmill in a clean and dry indoor environment.
Never leave or use the unit outdoors. Ensure the master power switch is off and the power cord is un-plugged from wall outlet.
TROUBLESHOOTING GUIDE
| Error code | Potential Reasons | Solution |
| No display | The controller is not powered on or is damaged | 1. First, check whether the over-load protector has tripped off, if yes, press it.2. Check the power supply switch, over-load protector and the controller's powercord and transformer to ensure well connection.3. The transformer is damaged; replace the transformer. |
| Safe | Safe lock falls down | 1. Place back the safe lock.2. Replace safe lock switch or magnetic sensor in the electronic meter; if the problem still fails to be solved, replace the electronic meter. |
| Error 1 | Communication failure from the driver to the electronic meter | 1. Check whether the connecting joint between the electronic meter and the core wire of the controller is loose; whether wires are damaged; whether the core wires are in correct connecting order.2. The transformer may be damaged. Check and replace a good one. |
| Error 3 | No sensory signal | 1. Check whether the photoelectric sensor directs to the hole on CD.2. Check whether wires of photoelectric sensor are damaged and whether terminals of the photoelectric sensor & speed terminals on the controller are firmly connected. |
| Error 4 | Power supply abnormality | Check whether the power supply voltage is less than 50% of the normal value; please ensure correct voltage and test again. |
| Error 5 | Self - inspection | 1. Check whether motor signal wires are well inserted; re-insert the signal wire joint to ensure that it is reliable;2. Replace the controller;3. Check whether the power cords from the electronic meter to the controller are well collected; dismantle the pillar to check connecting joints on each section of the wiring from the electronic meter to the controller; ensure that each wire core is well connected; or the reason may be the communication power cord defect (damaged or broke down); in such case, re-connect or replace wires. |
| Error 6 Motor problem | 1. Check whether motor wires are well connected; re-connect motor wires, or, if the problem still fails to be solved, replace the motor.2. It may be the system's self-protection against excessive current when the load exceeds the rated value; restart the machine.3. Some part of the treadmill is jammed so that the motor can not rotate, thus triggering the self-protection of the system against excessive current under excessive load; adjust the treadmill and restart it, or add lubricant.4. Check whether there is over-current sound or burning odor when the motor is running; replace the motor.5. Check whether the controller emits the odor of burning; if yes, replace the controller. | |

WARM UP AND COOL DOWN ROUTINE
The WARM-UP is an important part of any workout. The purpose of warming up is to prepare your body for exercise and to minimize injuries. Warm up for two to five minutes before aerobic exercising. It should begin every session to prepare your body for more strenuous exercise by heating up and stretching your muscles, increasing your circulation and pulse rate, and delivering more oxygen to your muscles.
COOL DOWN at the end of your workout, repeat these exercises to reduce soreness in tired muscles. The purpose of cooling down is to return the body to its resting state at the end of each exercise session. A proper cool-down slowly lowers your heart rate and allows blood to return to the heart.
HEAD ROLLS
Rotate your head to the right for one count, you should feel a stretching sensation up the left side of your neck. Then rotate your head back for one count, stretching your chin to the ceiling and letting your mouth open. Rotate your head to the left for one count, then drop your head to your chest for one count.
