An in-home treadmill can be a considerable financial investment, but it will save you from having to go to the gym to do your cardio workout. Your treadmill will require some attention, such as regular maintenance to keep your machine running smoothly. When you do have problems, such as erratic speeds, a little troubleshooting can point you in the right direction to get your treadmill up and running again.
Step 1
Check the power outlet. Treadmill manufacturers have different power requirements for their machines. If your unit is not powered correctly, or is plugged into a surge protector, this could cause erratic speeds. Consult your owner's manual or contact your manufacturer to make sure your outlet meets specifications.
Step 2
Test for a high tension belt. With the treadmill turned off, stand on the walking deck and push the belt in the direction it usually moves. If it is difficult to move, you may have increased tension between the belt and the deck.
Step 3
Feel the backside of the belt. If it is dry, you may need to lubricate the belt, although not all treadmill models require lubrication. Consult your owner's manual for lubrication instructions.
Step 4
Check the tightness of the belt. If the belt is slow relative to the selected speed, the belt may be overtightened. Lift the middle of the belt on one side of the treadmill. It should raise 3 to 4 inches off the walking deck. If not, the belt needs loosened. This usually involves using an Allen wrench to adjust the rear roller adjustment bolts on the end caps of the treadmill. Again, consult your owner's manual for specific instructions.
Step 5
Calibrate the speed settings. Some treadmills can be electronically reset if the incline or speed settings become faulty. Contact your manufacturer for calibration instructions.
