Wipe the deck and underside of the belt with a soft cloth; depending on your model of treadmill you should lubricate the walking deck at least every 6 months. Some unit use silicone spray or gel. Others use wax. Check your owner’s manual for what
the manufacturer recommends.
 
After you clean the belt and deck and lubricated the deck as needed center the belt on the walking platform and tighten the screws at the end of the treadmill.
 
Turn each bolt the same amount to keep the belt centered. Tighten the belt until it does not move freely on the rollers. Then with CAUTION straddle the belt and start the treadmill at low speed.
 
Wait for the belt to start moving then step on the belt. If it stops it is not tight enough. Step off the belt and tighten each side 1 turn then step on the belt again. Repeat as necessary.
 
Once you can walk on the belt at low speed without it stopping or slipping increase the speed to 3 miles per hour. This should be a fast walk.

If your unit has side rails hold the rails and try to stop the belt with pressure.
 
 IF ok then increase the speed to 5 MPH. Run on the treadmill, if you feel any slipping tighten the bolts another 1/2 turn each. Repeat if necessary.
 
If the belt is not centered, stand behind the treadmill and run the belt at full speed, if the belt is tracking to the left. Tighten the left bolt or screw 1/2 of a turn, and loosen the right bolt or screw 1/4 turn until the belt is centered.
