Tension Adjustment
Tools Needed:
• Hex Key
1 - Using a hex key, turn the left and right adjusting
bolts clockwise 1/2 turn (see Figure 1 and 1A).
NOTE: Use care to make each adjustment equal to
ensure proper belt alignment.
2 - Test the belt by running on the belt at
approximately 4 MPH. Then hold the handrail
lightly and resist the belt movement with your feet.
If walking belt slips, repeat Step 1.
Tracking Adjustment
Tools Needed:
• Hex Key
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 one 1/4 turn clockwise.
b: If the belt moves to the left, turn the left tension
bolt 1/4 turn clockwise.
NOTE: Run the belt for a minimum of 20 seconds
after making the first adjustment and
before making the second adjustment to
the belt tracking.
3 - After making an initial adjustment, run the treadmill
for five 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
