TENSIONING THE BELT PROCEDURE
Caution:
Over-tightening of the roller will severely shorten the life of the belt and may cause further damage to other components.
Running Belt:If when you plant your foot on the belt, you can feel a slipping sensation then the belt has stretched and is slipping across the rollers. This is a normal and common adjustment on a new treadmill. To eliminate this slipping, tension both the rear rollers Allen bolts 1/4 TURN as shown above. Try the treadmill again to check for slipping. Repeat if necessary, but NEVER TURN the roller bolts more than 1/4 turn at a time.
Frequency: Every 3 months
6
Drive Belt:
If you have tensioned the running belt and are still experiencing a slipping, adjust the tension screw. Then try the treadmill again to check for slipping.
7
DECK RE-WAXING PROCEDURE
Frequency: Every 3 month
Parts name: Silicon oil setParts number: SZTM74SOSPrice (USD): 0.6Use time : 1
Procedure:
1. Loosen the tension bolts at both ends.2. Pull the belt with your left hand and apply the silicon in the deck with
your right hand. (The volume of silicon applied is about 40ml)3. Tighten the tension bolts.4. Start the treadmill. Step on the treadmill belt to walk the silicon in.
Adjust the belt tension if necessary.5. With the clamp-on meter, measure the current draw of the motor.
(Clamp on either the red or the black wire.) The current should be less than 15Amps for 110V model. (less than 7.5Amps for 220V model.)
Caution:If deck is not to periodical add the waxing, between the deck and running belt will produce great friction make the deck and running belt to burn up and cut down the motor life .
8
CLEAN THE GROOVES PROCEDURE
Frequency: Every 3 months
Procedure:
1.Remove the drive belt and check the grooves in belt for dirt or dust and clean it.
3.Check the grooves in roller pulley for dirt or dust and clean it.
If dirty grooves in the drive belt, motor and roller pulley, there will be noises while running.
Caution:
2.Check the grooves in motor pulley for dirt or dust and clean it
9
Replace Right / Left side rail module procedure
If side rail LED will be not light, please replace Right / Left foot rail set, because replace side rail module is very difficult.
Caution:
Step.1 Take off the right / left end cap
Step.2 Remove the damage side rail
Step.3 Assembly the side rail and end cap
Step.4 Connect side rail wire to right rail wire (UP).
Step.5 Press “START” key, to run the machine confirm the side rail LED is good.

TROUBLESHOOTINGS
30
No display on console
Possible causes:
1. Breaker is damaged.
2. ON/OFF switch is damaged.
3. Incline power board is damaged
4. 20-pin console cable is damaged
5. PCB is damaged
Fix:1. Inspect the circuit breaker to see if it has tripped off.
(If it is tripped off….like diagram B, reset the breaker. And check which part is short-circuited. Then replace the short-circuited part.)
A B
2. The switch is turned to the "ON" position.( If the switch light isn't lit, replace the switch.)
2-1 Verify wire connection AC1 & AC2 on the MCB.
(Please refer the” MCB WIRING” ……page 10)3. Verify the MCB whether supply the +12VDC for console.
(Please refer the” MCB WIRING” ……page 15)4. Replace 20-pin console cable .5. Replace PCB
31
Running speed is not stable
Possible causes:
1. AC power voltage is too low.
2. Tension of drive belt or running belt is too loose.
3. Inverter is damaged.
4. Motor is damaged.
Fix:1. Check the power voltage by using voltage-meter to see if it is within
120V 15% or 230V 15%.
�If the power voltage isn't within the range, look for a qualified electrician for help.
2. Open the motor cover, if the belt has stretched and is slipping across the rollers when running.
�Adjust the belt tension (Please refer the” TENSIONING THE BELT PROCEDURE”……. Page5-6).
2. Replace new Inverter.
3. Replace new Motor.
32
Treadmill starts to run by itself
Possible causes:
1. The console cable is broken.
2. PCB is out of order.
3. Inverter is out of order.
Fix:1. Replace the console cable with a new one.
2. Replace the PCB.
3. Replace the Inverter .
All or some of the keys on console do not work
Possible causes:
1. Keypad connecting plug is not fit-in properly.
2. Keypad is damaged.
3. PCB is damaged.
Fix:1. Disconnect the keypad and replace the keypad, and check again.

33
Noises generated under motor cover
Possible causes:
1. The running belt tension is adjusted too tight.
2. The bearing of front roller is not installed correctly.
3. Dirty grooves of drive belt.
4. The motor is damaged.
Fix:1. Adjust the belt tension so that the belt does not start slipping and then
check if the noise has disappeared.
�Let the treadmill run, without using it, for at least 5 days because sometimes the bearing will settle and become quiet then check if the noise has disappeared.
2. Replace the front roller with a new one to see if the noise disappear.
3. Remove drive-belt and check the grooves in belt for dirt or dust and cleanif necessary. Clean also the motor pulley and the roller pulley grooves and check if the noise has disappeared.
4. The motor bearing is damaged.

Remark: Heart rate figure show up on the screen about in 15~20 sec.
2. If the heart rate figure still dosen't show up on the screen, Please inspect according to the step as below.
Step 1: Please make use of tools to confirm line have conduct.
41
Step 2: Please check the connection.
Check whether the heart rate cable is touching hand pulst metal (both of left hand and right hand).
Besides the other side of the heart rate cable should be connected with HR board.
Step 3: If you can't find any problem with above step, and the heart rate figure still can't showup, Please replace the heart rate board.
