5 / MAINTENANCE
To decrease the tension on the running belt, turn both bolts
counter-clockwise the same number of turns. Set the bolt
tension so that your last
1
¼4 turn removes the apparent belt
slippage and/or hesitation.
Centering the Running Belt
When you run, you may push off harder with one foot than the
other. This deflection can cause the belt to move off-center. The
severity of the deflection depends on the amount of force that
one foot exerts in relation to the other. This deflection is normal
and the running belt will often return to the center of the deck if
the weight distribution becomes more balanced or if the running
belt has a chance to reseat itself with no one on it. If the belt
remains consistently off-center, however, you will need to center
the belt manually.
Note: Before centering the belt, make sure it has the proper
tension. Refer to the previous section, “Adjusting the Belt
Tension,” for more information. Also, the machine should be run
at the speeds indicated without anyone on the belt.
To move the belt back to center:
1. Start the treadmill and press SPEED + until the speed is
approximately 4 mph (6.4 kph), as indicated on the display.
2. Locate the two large, steel 1/4-inch hex head bolts at the rear
of the treadmill (see Figure 5-1).
3. Observe whether the belt is running more towards the right or
left side of the deck.
If the belt appears to be moving to the left:
Using a 3/4-inch wrench (or an adjustable wrench), turn the
left bolt clockwise 1/4 turn (to your right). Wait for one minute
for the results of this adjustment to take effect. This action
moves the belt to the right and back to center.
If the belt appears to be moving to the right:
Using a 3/4-inch wrench (or an adjustable wrench), turn the
left bolt counterclockwise 1/4 turn (to your left). Wait for one
minute for this action to take effect. This action moves the
belt to the left and back
to center.
4. If the belt is still not centered, repeat step 3 until it is.
5. After the belt is centered, increase the speed of the belt to 10
mph (16.1 kph) by pressing SPEED + and verify that the belt
is running smoothly. Repeat step 3 as necessary.
If the above procedure is unsuccessful in resolving belt wander,
you may need to increase the belt tension. See the previous
section, “Adjusting the Belt Tension,” for more information.
CAUTION: BE CAREFUL NOT TO
OVERTIGHTEN THE RUNNING BELT
TENSION. OVERTIGHTENING CAN
CREATE EXCESSIVE PRESSURE ON THE
FRONT AND REAR ROLLER BEARINGS,
CAUSING PREMATURE ROLLER
BEARING WEAR AND/OR FAILURE.
