If the running belt is slipping during use, turn off and unplug the treadmill.
Using the 6 mm Allen Wrench provided, turn both left and right rear roller
adjustment bolts 1/4 turn clockwise, then turn the main power switch back
on and run the treadmill at a speed of 8-10 KPH. Run on to the running belt
to determine if the belt is still slipping. Repeat this procedure until the belt
no longer slips.
