ADJUSTMENTS
The running belt and its headroller, drive belt, tailroller, and running deck are designed to be self-centering, slip-free, and smooth-
operating without the need for frequent adjustments. Running belt sideward movement, slipping, or grinding after extended use,
or thumping during initial use, may be corrected by the following procedures:
Change Sideward Movement to TRACKING: If the running belt is not centered on the tailroller and is either too far left or
right, adjust tracking using the following steps:
1. Turn the treadmill on. Increase treadmill speed to 3.0 mph (5.0 kph).
2. Adjust tracking by adjusting the tailroller Allen screws (located at the back
sides of the tailroller) with a 1/4" Allen wrench in 1/4-turn increments.
If the running belt is tracking to the left, adjust the running belt to track
to the right. Tighten the left tailroller Allen screw by turning clockwise, or
loosen the right tailroller bolt by turning counter-clockwise.
If the running belt is tracking to the right, adjust the running belt to track
to the left. Tighten the right tailroller Allen screw by turning clockwise or
loosen the left tailroller bolt by turning counter-clockwise.
3. After the running belt appears to be tracking properly, increase the tread-
mill speed to 10.0 mph (16.0 kph) and verify that the belt stays centered.
Slipping-Running Belt: Remove the motor shroud and operate the treadmill slowly at 1 to 2 mph (2 to 3 kph). While observing
the headroller, walk on the belt and try to slow it down by gently applying pressure with your feet while holding the handrails. If
only the running belt, and not the headroller, slows down, tighten the running belt by turning both the right and left tailroller
adjustment bolts clockwise 1/4-turn. Repeat this adjustment until the running belt no longer slips, ensuring that you turn both
tailroller bolts an equal number of turns. Re-install the motor shroud. If the headroller and the running belt both slow down, tight-
en the drive belt as described under “Slipping-Drive Belt”, below.
Slipping-Driver Belt: Adjust the treadmill incline to 5% to provide clearance
underneath. Set the ON/OFF switch to the OFF position and unplug the treadmill.
Remove the motor shroud. With a 1/2" socket wrench, loosen the four motor bolts.
Use the socket wrench to adjust the tension bolt in the middle of the motor brack-
et 1/4-turn clockwise, stretching the drive belt. Tighten the motor bolts and re-
install the motor shroud. Plug the treadmill in, turn it on, and test for slipping as
described under “Slipping-Running Belt”, above. Repeat this step as necessary.
Thumping: Turn the treadmill off. Turn the right and left tailroller adjustment
bolts counter-clockwise with the 1/4" Allen wrench until the running belt is loose.
Note the number of times each bolt is turned. Remove excess accumulated running
deck wax from the tailroller with a credit card, a putty knife, or other flexible plas-
tic implement. Tighten the running belt by turning the adjustment bolts clockwise
the same number of turns as they were loosened. Turn the treadmill on and check
for sideward movement and/or slipping of the running belt. Tighten the tailroller
adjustment bolts further, if necessary, in 1/4-turn increments.
REWAX BELT
Periodic running belt rewaxing virtually eliminates belt down time, and maximizes the life of the belt. Whenever the present dis-
tance is 2000 miles (or 3000 km) more than the LAST DECK (last deck service), the start-up display will scroll REWAX BELT.
This is a reminder to have your maintenance or service provider perform the 5-minute belt rewaxing procedure at your conven-
ience. (Immediate service is not required). Wax is included in the treadmill.
TOOLS & MATERIALS
Bottle of Wax Powder (1)
Clean Towel (1)
Paint Stick or Ruler (1)
Diluted All-purpose Cleaner (409), or Bristle Brush
PROCEDURE
Apply wax powder while belt & deck are still warm (5 minutes minimum use) for optimum benefit.
1. CAUTION: TURN TREADMILL POWER OFF AND UNPLUG THE POWER CORD BEFORE REWAXING THE BELT.
2. CLEAN DECK & BELT:
A. Using the paint stick or ruler, slide a towel under the middle of the belt from one side of the frame to the other.
