Sport Craft recommends that a small amount of the lubricant provided on your parts tray be applied approximately every 50 hours of use.
2. In order to apply the lubricant your must follow these steps:
A. Unplug the treadmill from the electrical outlet.
B. Loosen the belt tension a small amount by turning the roller adjustment screws at the end of the treadmill counter clockwise (to the left). Use the hex key that was provided with your treadmill. You may need to turn both these screws at least 2 full turns or more to provide the slack you need to perform the lubrication.
C. When you can lift the edge of the treadmill walking belt a small distance from the deck, one inch or so, you will have enough space to apply the lubricant.
D. Snip the end of the “needle” top of the silicone container with a scissors or other sharp object. Be careful not to cut off too much of the top. You need a very small opening to properly apply the lubricant. There is a cap provided to close the container after use. Push the “needle” top of the container under the belt as far as you can and apply the silicone directly to the deck. The silicone should be applied in drops or in a very thin stream. Apply the silicone the entire length of the deck on both sides of the walking belt. One application per side is all that is needed.
E. Tighten the roller adjustment bolts by turning them clockwise (to the right) the exact same number of turns that you used to loosen them. You must now make sure that the treadmill walking belt is centered.
F. Plug the treadmill in to the electrical outlet.
G. With no one on the treadmill, start it at a slow speed, less than 2.5 MPH. Watch the belt for 30 to 60 seconds. If it is running in the center of the deck, increase the speed to 5.0 MPH and observe if it stays in the center of the deck. If
Over adjusting the belt to tight can severely damage your treadmill
1. You want to make sure that your walking belt is resting on the walking deck surface and not floating above the walking deck surface.
2. Once you have your belt laying flat on your walking deck you can check the tension by putting the tip of your finger under the middle of the side of the belt and lifting up.
Belt should lift 1 to 1.5 inches
Less than 1 inch is too tight
Over 1.5 inches is to loose
3. Next make sure your adjustment bolts are even. If you keep your adjustment bolts even your walking belt will stay even.
