Depending on where the treadmill is placed, you may experience dry air, causing a common experience of static electricity. You can notice that by walking across a carpet and then touching a metal object. On your treadmill you may experience a shock due to the build-up of static electricity on your body and the discharge path of the treadmill.
If you experience this type of situation, you may want to increase the humidity to a comfortable level through the use of a humidifier.
Check your machine regularly for rust. If rust starts to appear on the screws it means the item is not housed in the correct environment and will need to be moved to a more suitable room. Any rust will indicate there may be moisture in the air and as a result this could impact on the integrity and performance of your machine.

TREADMILL CLEANING
Keep the running belt free of dust and debris for smooth running and preventing injuries. Dust/debris may cause damage to the electric motor and other moving parts.
Over time the motor will pull in dust/debris so it is advised every so often when maintenance is being performed to remove the motor cover and vacuum out of the motor.
After every workout use a neat, dry cloth for cleaning the treadmill and the handlebars to prevent the machine of corrosion. Wipe away any sweat that may have dripped onto the running belt. Avoid scratching the display by using a soft cloth.
Contaminants, such as hand lotions, oils or body powder, may come off on the sensor plates. These can reduce sensitivity and interfere with the pulse signal. It is recommended that the user has clean hands when making contact with the sensor plates.
Clean the handles using a cloth dampened with water.
For cleaning the console unplug the machine and clean with a dust free cloth. For further cleaning, use a soft cloth or paper towel dampened with water. Do not use abrasive or chemical cleaning agents.
When not using product for an extended period of time the product should be disconnected from the power supply.

WARNING

1. Only use water to clean and dust. Do not use any cleaning product because they may damage the treadmill.
2. Be careful not to spill or get excessive moisture between the edge of the display panel and the console, as this might create an electrical hazard or cause failure of the electronics.
3. Direct spraying could cause damage to the electronics and may void the warranty.

WARNING

1. Use only JLL ® replacement parts.
2. Unplug unit and let sit 10 minutes before cleaning or performing maintenance.
3. Keep water and liquids away from electrical parts.
4. Electrical charge can remain in unit after unplugging.
5. If you allow your machine to become rusty, this will affect your warranty.

WARNING: EQUIPMENT HAZARD
To avoid serious injury or death:

• Replace worn or damaged components immediately and do not use until repair is completed.
• Unplug unit when not in use or when performing regular maintenance.

TREADMILL BALANCE

Place the treadmill on a level floor to avoid it being off-balance. If that is not possible, adjust the treadmill by adjusting the rubber feet located underneath the frames.

Check if the treadmill is balanced:

1. Stand on the machine with your feet on the side frames.
2. Put your weight on the right side first and then switch to the left side.
3. If you feel any vibrating whilst using the treadmill, adjust the rubber feet located at the base of the frame.

TREADMILL LUBRICATION
If the level of friction between the deck and the belt is high, it will damage the motor and electronics. The running board must be lubricated by a special lubrication oil after a period of usage. A well-lubricated treadmill will be smooth when running and will last longer.
Recommendation (these are just a guideline):

• Less than 3 hours per week of use: Lubricate it every 6 months.
• 3-6 hours per week: Lubricate it every 3 months.
• More than 6 hours per week: Lubricate it every month.

5 STEPS TO LUBRICATE YOUR TREADMILL

1. Unplug the treadmill.
2. To get access to the deck lift the belt on the treadmill up with your fingers or with something flat and not sharp.
3. Look at the running board or touch it to check if it is oily or not. In case of dryness, use the lubrication oil provided and apply it on the running deck by spreading a straight line down the side of the deck. Ensure that the middle of the board is lubricated.
4. Repeat on the other side.
5. Turn on the machine and leave it running for around 2-3 minutes at 3-4 km/h.
   Walk on the treadmill to help spread the lubrication oil.

ADJUSTING THE RUNNING BELT
After a period of time, the user will feel there is a pause sensation whilst running. The running belt can become loose and stretch a bit over time causing a slipping sensation if it is not adjusted and tightened when needed.
If the belt is too tight, this may cause damage to your motor and/or roller. A belt too loose or too tight can cause wear and tear of both the belt and the board.

HOW TO CHECK IF THE RUNNING BELT IS LOOSE

You can check this every time you use the treadmill by setting the speed to 2-3 km/h then walking on the machine and try to stop the running belt with your feet while holding the handlebars and pulling your body in the opposite direction. If the belt stops, it means that it is loose and needs to be tightened.
Another way is checking if the gap between the running belt and the running board is smaller than 5-6 mm, that means that the running belt is loose. TIGHTENING THE RUNNING BELT

1. Power off the treadmill.
2. Turn the two belt adjustment screws, located at the rear, clockwise to tighten the belt slightly by quarters.
3. Get back on the treadmill and check the belt (read description above). If it is still loose, re-adjust the belt screws by another quarter until you get the required tension on the belt.
4. Run the machine on its own for 1-2 minutes to see if the belt stays in the middle.
5. Do the final test. Leave the machine running for a couple of minutes at 6-8 km/h.
6. If the running belt stays in the centre, you can use the treadmill straight away.

ADJUSTING THE BELT WHEN IT IS NOT CENTERED

Usually between the frames and the running belt there should be a gap of 5-6 mm on both sides. If that gap is different it means that the belt is eccentric. So you have to put it back to the right position by following these steps:

1. Power on and set the speed at 2-3 km/h and adjust the screw at the end of the treadmill slowly with the Allen key.
2. If the belt slants to the left, adjust the left bolt clockwise or adjust the right bolt anti-clockwise. If the belt slants to the right, adjust in the opposite manner.
3. While adjusting the belt, check if the gap of difference has disappeared, if it is still there, screw the bolt again. Repeat this procedure until the running belt is in the centre. It does not need to be aligned perfectly, but ensure it is not scraping or rubbing on anything on the sides.
4. Set the speed at 6 km/h to check if the running belt is still in the same position.
   Once you have checked that, the treadmill is ready to use.

ADJUSTING THE MOTOR BELT
After a period of time, the user will feel there is a pause sensation whilst running. That may be due to a loose motor belt, so adjusting it would be necessary. First of all, you have to check if it is loose following the steps below.

HOW TO CHECK IF THE MOTOR BELT IS LOOSE

1. Unplug the treadmill.

2. Remove the motor cover by unscrewing the bolts on each side. You will see the motor located on the left hand side of the treadmill.

3. An easy way of checking is by touching the drive belt to feel if it is slack.
   If you can wiggle the belt up and down, it means that the drive belt is loose.

4. You can check this every time you use the treadmill by setting the speed to 2-3 km/h then walking on the machine and try to stop the belt with your feet while holding the handlebars and pulling your body in the opposite direction. If the motor stops, it means that it is loose and needs to be tightened.

TIGHTENING THE MOTOR BELT

1. Ensure that the treadmill is unplugged from the power source.
2. Locate the four bolts holding the motor.
3. Loosen those four bolts, but do not remove them.
4. Locate the long tensioning bolt that goes from the front edge of the treadmill to the front edge of the motor pallet.
5. Turn the Allen key clockwise to tighten the tensioning bolt just enough to stop it from slipping.
6. Check the tension on the motor belt.
7. Power on the machine and check if the motor belt is still loose (See previous chapter).

NOTE : Do not tighten the motor belt too much as this could cause the motor shaft to snap.
