Tighten the rear roller bolts only enough to prevent slippage at the
front roller. Turn both tread-belt tension adjustment bolts with a
10mm allen wrench in increments of 1/4 to 1/2 turn each and inspect
for proper tension by walking on the belt at a low speed, making sure
the belt does not slip. Keep tensioning the bolts until the belt stops
slipping.
• If you feel the belt is tight enough, but it still slips, the problem may be
a loose Motor drive belt under the front motor cover.
Do not overtighten
Over tightening will cause belt damage and premature bearing
failure.
Treadbelt tracking adjustment
The performance of your treadmill is dependent on the frame running
on a reasonably level surface. If the frame is not level, the front and
back roller cannot run parallel, and constant belt adjustment may be
necessary.
The treadmill is designed to keep the tread-belt reasonably centered
while in use. It is normal for some belts to drift near one side while
the belt is running with no one on it. After a few minutes of use, the
tread-belt should have a tendency to center itself. If, during use, the
belt continues to move toward one side, adjustments are necessary.
To set treadbelt tracking
Use a 10mm Allen wrench to adjust the rear roller. Make tracking
adjustments from the left side only. Set belt speed at approximately 2
to 3 mph.
