Belt Adjustments
Tread-belt tension adjustment - Belt tension is not critical for most users. It is very important
though for joggers and runners in order to provide a smooth, steady running surface. Adjust-
ment must be made from the rear roller with the 6mm Allen wrench provided in the parts
package. The adjustment bolts are located at the end of the step rails as shown in the dia-
gram below.
Tighten the rear roller only enough to prevent
slippage at the front roller. Turn the tread-belt
tension adjusting bolts 1/4 turn each and inspect
for proper tension by walking on the belt and
making sure it is not slipping or hesitating with
each step. When an adjustment is made to the belt
tension, you must be sure to turn the bolts on
both sides evenly or the belt could start tracking to
one side instead of running in the middle of the deck.
DO NOT OVERTIGHTEN – Over tightening will cause belt damage and premature bearing
failure. If you tighten the belt a lot and it still slips, the problem could actually be the drive belt
- located under the motor cover - that connects the motor to the front roller. If that belt is loose it
feels similar to the walking belt being loose. Tightening the motor belt should be done by a
trained service person.
Treadbelt Tracking Adjustment
The treadmill is designed in that way, that the tread-belt remains reasonably centered while in
use. It is normal for some belts to drift near one side while in use, depending on a user’s gait
and if they favor one leg. But if during use the belt continues to move toward one side,
adjustments are necessary.
SETTING TREAD-BELT TRACKING
An 6mm Allen wrench is provided for this adjustment. Make tracking adjustments on the left
side bolt. Set belt speed at 3 kph. Be aware that a small adjustment can make a dramatic
difference which may not be apparent right away.
If the belt is too close to the left side, then turn
the bolt only a 1/4 turn to the right (clockwise)
and wait a few minutes for the belt to adjust
itself. Continue to make 1/4 turns until the belt
stabilizes in the center of the running deck.
If the belt is too close to the right side, turn the
bolt counter-clockwise. The belt may require
periodic tracking adjustment depending on use
and walking/running characteristics. Some users may affect tracking differently. Expect to
make adjustments as required to center the tread-belt. Adjustments will become less of a
maintenance concern as the belt is used. Proper belt tracking is an owner responsibility
common with all treadmills.
