Question about Exercise & Fitness
When walking or running the treadmill is jerky as if the motor loses slight power It kicks you slightly and then is Ok and then does it again
1) Lube the deck belt, this happen because the lack of maintenance, use 100% silicones or wax, check your instr. manual
2) Lube the rollers bearint with wd-40
3) Test the drive belt motor, for cracking or worn belt
4) Test the input voltage motor, if there are the motor need repair, see my personal TIPS for motor help.

SOURCE: treadmill may be slipping
Depending if this is a new issue or old, It could be a couple of issues. Check the belts for slipping. Proper tension on walking belt (check your manual) or drive belt -remove the cover and you might be able to see if the belt is slipping or it could be a load issue (electronics not sensing added load fast enough). My bet is belt tension. Also Lubricate,lubricate,lubricate

B) Walking Belt/Motor Belt too Tight:
If you have adjusted the walking belt or motor belt recently, check for this problem. When the belts start slipping, some people just crank
down the belts and on treadmills, tighter is not necessarily better. The tighter the belts, the more the drive system has to work to keep
everything moving. You should be able to lift the walking belt (with the treadmill unplugged) in the center of the treadmill about 3" without
straining. Tighter belts should be loosen but make sure you don't create a dangerous slipping situation by loosening.
The motor belt (with the treadmill unplugged) should be able to be turned by hand to almost a 90 degree angle from its normal operating
position. Loosen the belt if too tight. Make sure to test for slipping
and if it does with the proper tension, replace the motor belt.
