WALKING BELT TENSION ADJUSTMENT
As the treadmill’s walking belt stretches through use it will
become necessary to adjust tension on the belt. This often
occurs within the fi rst few months of use. Adjust the belt
tension whenever the belt slips or moves unsteadily during
operation.
The belt tension is adjusted by moving the rear roller of
the treadmill back to reduce slack. This is accomplished
by turning the adjustment bolts located on the back of the
treadmill.
1. Using the provided hex key, turn the left and right adjust-
ing bolts clockwise ½ turn. The adjusting bolts are ac-
cessed through the holes provided in the end caps. Use
care to make each adjustment equal to ensure proper
belt alignment.
2. Test the belt by running on the belt at about 4 MPH (6.4
KPH). Hold the handrail lightly and resist the belt move-
ment with your feet. If walking belt slips, repeat Step 1.
WALKING BELT TRACKING ADJUSTMENT
Perform this procedure whenever the belt moves to one
side or the other. Stay off the belt when adjusting the
tracking.
1. Start the treadmill at minimum speed and incline.
2. Increase speed to 5 MPH (8 KPH) and make the
following adjustment:
a. If the belt moves to the right, turn the right tension
bolt ¼ turn clockwise.
b. If the belt moves to the left, turn the left tension bolt
¼ turn clockwise.
NOTE: Run the belt for a minimum of 20 seconds
after making the fi rst adjustment and before
making a second adjustment to the belt tracking.
3. After making an initial adjustment, run the treadmill for
fi ve minutes and observe how the belt tracks. If the
belt continues to move away from the center, adjust the
appropriate side as in Step 2 until properly centered.
BELT REPLACEMENT
If the walking belt becomes worn from heavy usage, it
may need to be replaced. Call an Authorized Nautilus®
Fitness Retailer to obtain service.
