alot of times you have to remove the wax spray nozel and clean as the wax hardens over it

If you have adjusted the tension on your belt to the max, it is more than likely time to replace your running belt. The running belt naturally stretches over time. I would suggest replacing the belt and flipping your deck. If the deck has already been flipped once, then you would need to replace the deck as well.

It may not be sticking, but instead slipping on the front roller. You can resolve this by simply tightening the running belt. This adjustment will be done by using the rear roller.

Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for how to tension a treadmill running belt.
  1. Adjust for no slippage of the treadmill walking belt on the front roller (Often referred to as the "Stomp Test")
    1. This procedure works well for a previously installed belt that is now slipping.
    2. Underside of belt should be free of any glazing/wax buildup.
    3. Rollers must also be free of wax buildup.
    4. Be sure belt tracking/centering is correct before proceeding.
    5. The most popular speed for this adjustment is 2mph to 3mph.
    6. Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
  2. This procedure requires two belt gauges or calipers
    1. This procedure works well when installing a new belt.
    2. This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
    3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
  3. Gauges or Calipers unavailable
    1. Release the tension on the belt.
    2. Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
    3. Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
    4. Test for proper tracking and tension, adjust if necessary.

It sounds like you have a reed switch malfunction. The reed switch is located next to the front drive roller at the drive pully under the motor hood. It is the little black wire with the pick up on the end. It need to be about an 1/8th of an inch away from the magnet that is mounted in the pully. If it looks lined up and is not twisted, check the other end. It is plugged into the controller on the other side. If all looks fine, you just might nee to get another one.

Hope this helps

You have to remove the spray nozzle and heat it with a torch to clear the hardened wax. The nozzle twists off.
