2.  Test the belt by running on the belt at about 4 
MPH. Hold the handrail lightly and resist the belt 
movement 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 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.
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.

IMPORTANT Do not over tighten walking 
belt! The belt need only be tight enough to prevent 
it from slipping during use. Excessive belt tension 
will decrease belt life and can damage the treadmill 
rollers and drive system.
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.

IMPORTANT Treadmill is extremely 
heavy and awkward and requires two people to

switch on the treadmill, then remove the treadmill 
power cord from the power source before moving 
the treadmill.

AND THE TREADMILL CIRCUIT BREAKER IS ON, THE

IS TURNED OFF.

to the new site using the wheels on the front of 
the treadmill.
When storing for prolonged periods, cover the 
treadmill with a dust cover. Do not store in damp 
areas. Do not store the treadmill on its end as it could 
fall on someone.
Using After Storage Period
Before using the treadmill again after moving or 
storage, check the power cord and all attachments to 
be sure they are undamaged and securely connected, 
then test the system for proper operation.
