TENSIONING THE BELT PROCEDURE

Frequency: Every 1 months

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.

Perfect Tension of Running Belt:

0.9~1.1 lbs

Page 12

Drive Belt:

If you have tensioned the running belt and are still experiencing a slipping, adjust the tension screw of spring. Then try the treadmill again to check for slipping.

Page 13

DECK RE-WAXING PROCEDURE

Purpose : To ensure the maximum life of your treadmill, follow these steps

Purpose :

regular intervals.

The timing of running belt and deck maintenance :

The timing of running belt and deck maintenance

1. Each 6 months to lubricate by wax powder.

2. One year to flip the running deck.

3. Two years or over 6,000 hrs of usage to replace new running belt and deck.

4. In the regular maintain, If the motor over current that has to lubricate by wax powder

★ Take a motor current reading while a 70-90 kg user is walking on the machine at

5KM. If it is over limited current , wax the deck.

The limit current for each motor as below :

The limit current for each motor as below

Limited CurrentNormal CurrentMotor type

11A<9A220V DC

20A<15A110V DC

220V AC

5.5A<5A

110V AC

Recheck the motor current as above –

If the motor current is still over limited current, Please flip the deck or replace the

belt.

Page 14

WAXING PROCEDURE:

1. Warm deck and belt by walking on treadmill for 3 or more minutes at a minimum speed of 3 mph (4.8 kph).

2. Turn off and unplug the treadmill.

3. Sprinkle approximately 1/2 scales of wax under the running belt. (It is useful to lightly blow the wax to the center of the belt.)

4. Turn the unit on and walk the wax in for 3-4 minutes at 1 mph. Walk all over the belt to ensure smooth wax distribution.

5. Once wax is walked into the belt and deck repeat procedure for checking the motor current to ensure that the belt and deck are not to worn for wax to improve the friction.

Be careful to monitor wax buildup on the rollers – too much wax can cause issues and technicians need to monitor the rollers if they continually wax units.

1. One big bottle with 1kg wax powder

2. A small bottle for maintenance.

CLEAN THE GROOVES PROCEDURE

Frequency: Every 3 months

Caution:

If dirty grooves in the drive belt and motor, there will be noises while running.

Procedure:

1.Remove the drive belt and check the grooves in belt for dirt or dust and clean it.

2.Check the grooves in motor pulley for dirt or dust and clean it

Page 35

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. MCB 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”……. Page11~12).

Page 37

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 clean if necessary. Clean also the motor pulley and the roller pulley grooves and check if the noise has disappeared.

4. The motor bearing is damaged.

Replace the motor.

Remark: Heart rate figure show up on the screen about in 5~10 sec.

2. If the heart rate figure still doesn't show up on the screen, Please inspect according to the step as below.

Step 1: Using multi-meter to confirm the wire has conduct.

Page 40

Step 2: Please check the connection.

Check whether the heart rate cable is touching hand pulse 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 show up, Please replace the heart rate board.
