same bolt. Once the running belt has been adjusted closer to the center of the
treadmill use about 1/4 of a turn until the belt has been stabilized.
B. After the belt has been centered, check the belt tension again. Make sure the running
belt tension is tight enough so that the belt does not slip or hesitate when stepped on.
Walk on the treadmill at 3.5-4 mph (5.6-6.4 kph) and every 4th to 5th step throw your
weight into your step to feel if the belt is slipping. If the belt does slip, use a wrench to
equally tighten both rear roller adjustment bolts 1/2 of a turn (clockwise). Adjust the belt
until no further slipping is felt. If the running belt continues to slip the drive belt could
be loose.
NOTE: The springs may eventually compress slightly. If they compress the silver washers
may no longer be flush with the protruding tab on the end caps when the belt is
properly tensioned. The washers will be positioned deeper into the end cap and
not be as visible.
Checking the Belt and Deck Surfaces — The running belt and deck should be checked
periodically for any excessive wear. In an effort to make sure that the running belt operates
properly, visually inspect the belt on a weekly basis to make sure that there are no tears or
fraying in the belt material.
To inspect the edges of the belt, it is necessary to remove the motor cover and plastic side
rails. Follow these steps:
Tools Required
• Phillips head screwdriver
• 3/16" Allen wrench
• Dry towel
1. Turn the power off.
A. Turn the main power switch on the front panel to the off (O) position.
B. Unplug the treadmill from the power outlet.
2. Remove the motor cover and side rails.
A. Remove the two Phillips head screws that fasten the motor cover to the frame. Lift the
cover and set it aside. This will allow you to remove the side rails. See Figure 2.
B. Using a 3/16” Allen wrench, remove the two button head screws on the sides of each
side rail. See Figure 2.
C. Grasp the top edge of each side rail and pull up and away from the deck. This will
enable you to see the deck and edges of the belt. It is not necessary to remove the
side rails completely off the frame.
3. Check the belt and deck condition.
A. Look at the edges of the belt while you roll it by hand. If the belt has any rips or looks
