WALKING BELT CENTERING AND TENSION ADJUSTMENT
The walking belt may occasionally need to be centered and tightened.
When the walking belt is slipping, it is sometimes difficult to
determine if the walking belt itself needs tightening or the
drive belt tension needs adjustment. If the sides of the walking
belt can only be raised approximately 2-3 inches off the board,
the walking belt is generally tightened sufficiently. However,
the following procedures can be utilized to determine exactly
which belt should be tightened if the walking belt is slipping:
1. Remove the six screws holding the motor cover and gently
lift the motor cover from the treadmill.
2. Set the speed of the treadmill at approximately 1.5 mph.
Bracing yourself with your hands on the handrail and one
foot on the plastic side rail, plant the other foot firmly on
the walking belt and try to stall the belt. If you can stop the
walking belt and the front roller does not continue turning
but the motor pulley continues to turn, then the drive belt
needs tightening and the adjustment instructions found at
the bottom of this page should be followed. If you can stop
the walking belt and the front roller continues to turn, the
walking belt needs to be tightened and the instructions
that follow should be used.
TO ADJUST WALKING BELT TENSION:
• Run treadmill at approximately 3.5 mph.
• Using
3
⁄
16
˝ Hex wrench, turn both the right and left
adjustment bolts ONE full turn clockwise
• If slipping continues during use, repeat above steps.
NOTE:
It is recommended that the hex wrench clip be
attached to a convenient spot on the treadmill, and the
hex wrench kept in the clip.
DO NOT OVERTIGHTEN
the walking belt. This may cause
reduced motor performance and excessive roller wear.
NOTE:
When properly tightened, the sides of belt can be
raised approximately 2-3 inches off the board.
TO CENTER WALKING BELT:
• Place treadmill on a level surface.
• Run treadmill at approximately 3.5 mph.
• If the belt has drifted to the right, turn the right adjusting
bolt
1

counterclockwise.
• If the belt has drifted to the left, turn the left adjusting bolt
1

⁄

TO TIGHTEN DRIVE BELT:
1. Unplug treadmill.
2. Remove six (6) Phillips screws from motor cover. Remove
motor cover and set aside with screws.
3. Using a
1
⁄
2
˝ wrench or
1
⁄
2
˝ deep socket, tighten nut on
J-Bolt assembly. Nut may need to be tightened 2-3 turns.
4. With motor cover still off treadmill, plug treadmill in and
test drive belt for slippage.
5. If tension is adequate, reinstall motor cover. If further
adjustments are needed, repeat step #3.
