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.
How to apply lubricant
Lift one side of running belt. Pour some lubricant under the centre of the
running belt on the top surface of the running deck. Run on the treadmill at a
slow speed for 3 to 5 minutes to evenly distribute lubricant.
Note: Do not over lubricate running deck. Any excess lubricant that comes
out should be wiped off.
