Routine Maintenance Schedules
Performing routine maintenance will help prevent unnecessary wear to the treadmill and/or injury to the
user. The maintenance schedules are meant only to serve as a guide. Depending on where and how the
treadmill is being used, more frequent routine maintenance may be required.
SECTION 1: MAINTENANCE
6
Daily
• Inspect the power cord and walking belt for wear.
• Check the position of the walking belt. Verify it is not rubbing against the frame. The belt should be
evenly spaced on the deck within 0.25 inches of each side rail. Adjust the belt if necessary.
• Check the optional side handrails to ensure they are fastened securely.
• Remove potential hazards from the treadmill area.
Cleaning
Keeping the Nautilus® Commercial series T9 treadmill clean on a regular basis will help to improve
operation and increase the lifespan of the components.
Daily
• Keep the treadmill and controller free of dust and debris. Use a damp sponge to wipe the exteriors
and walking belt; do not soak surfaces. Dry all surfaces thoroughly.
Weekly
• Elevate the treadmill to maximum incline and vacuum the floor under it to prevent excess dust and
dirt from interfering with operation.
• If the magnetic key is being used, check it for rust. If you detect rust, replace the magnet. Rust on
the magnetic key will cause power-up problems.
Treadmill Interior
DANGEROUS VOLTAGES ARE PRESENT UNDER THE TREADMILL HOOD. EXERCISE
CAUTION WHEN PERFORMING SERVICE TO THE ELECTRICAL COMPONENTS UNDER
THE HOOD.
SECTION 1: MAINTENANCE
DRY MOP THE DECK UNDER THE BELT ONLY. DO NOT ADD ANY LUBRICANTS—ADDING
LUBRICANTS CAN RUIN THE PROPRIETARY FRICTION-CONTROL SURFACE.
DO NOT USE DETERGENTS OR CLEANING AGENTS ON ANY PART OF THE DECK.
DO NOT LET LIQUID ENTER THE TREADMILL OR CONTROLLER. IF IT DOES, THE
EQUIPMENT MUST BE INSPECTED AND TESTED FOR SAFETY BY A NAUTILUS®-
APPROVED TECHNICIAN BEFORE IT CAN BE USED AGAIN.

SECTION 1: MAINTENANCE
DO NOT OVERTIGHTEN THE WALKING BELT. DO NOT TORQUE ADJUSTMENT SCREWS
BEYOND 80 IN-LBS (9 N-M) MAXIMUM. OVERTIGHTENING THE BELT WILL REDUCE
BELT LIFE AND DAMAGE THE ROLLER BEARINGS.
Depending upon the treadmill environment, dust and or lint can accumulate under the hood. Clean the
interior of the treadmill following the procedure below:
1. Turn the treadmill circuit breaker off, and unplug the treadmill power cord.
2. Remove the two (2) screws on the treadmill hood.
3. Lift off the hood.
4. Clean inside the unit.
5. Reinstall the hood and the two (2) screws.
6. Plug in the treadmill power cord, and switch on the treadmill circuit breaker.
Adjusting Belt Tension
Adjust the belt tension whenever the belt slips or
moves unsteadily during operation by following the
steps below:
1. Start by loosening the two (2) adjustment bolts
(see Figure 1).
2. With the walking belt loose, place two marks
35 inches (89 cm) apart on each side of the belt
near the edge. The belt must be loose enough for you to move it from side-to-side on the front or
rear roller (see Figure 2).
3. Turn the adjusting bolts clockwise by equal amounts until the marks are between 35-3/16 inches
and 35-5/16 inches apart. Proper tension for the walking belt is between .5%–.6%. This should
be about six full turns of each adjustment bolt from the point where the belt begins to stretch.
Important: Do not exceed 35-5/16 inches.

4. Test the belt by running on the belt at about four (4) mph. Hold the handrail lightly and resist the
belt movement with your feet.
5. If you feel the belt slip on the front roller, increase the tension of each adjustment bolt by 1/2 turn
and re-test. If you feel the belt slip again, check the tensioner adjustment.
Adjusting Belt Tracking
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 grade.
2. Increase speed to six (6) mph, and make the following adjustment:
2.1. If the belt moves to the right, turn the right adjustment bolt 1/4-turn clockwise.
2.2. If the belt moves to the left, turn the left adjustment bolt 1/4-turn clockwise.
3. After making an initial adjustment, run the treadmill for five (5) minutes and observe how the
belt tracks. If the belt continues to move away from the center, adjust the appropriate side until
properly centered.
Replacing the Walk Belt
Perform this procedure whenever the walk belt is still too loose after adjusting the tension or when the
belt is worn or frayed.
SECTION 1: MAINTENANCE
DO NOT USE ALL YOUR WEIGHT TO RESIST THE BELT MOVEMENT. TOO MUCH
RESISTANCE APPLIED TOO LONG (MORE THAN TWO SECONDS) MAY SHUT DOWN
THE SYSTEM. (VARIOUS ERROR MESSAGES WILL APPEAR IF THIS OCCURS. CYCLE
POWER TO RESUME NORMAL OPERATION.)
DO NOT CUT THE BELT—DOING SO WILL CAUSE THE REAR ROLLER TO FALL AND SNAP
THE ALIGNMENT PINS ON THE END CAP.
