If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened.
In most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common
adjustment. Make sure that the unit is turned off and not running. To eliminate this slipping, tension
both the rear roller bolts with the appropriate sized Allen wrench, turning both the left and right bolt 1/4
TURN as shown below. Try the treadmill again to check for slipping. Repeat if necessary, but NEVER
TURN the roller bolts more than 1/4 turn at a time.
1 | If the running belt moves rapidly to one side when performing the next step, press the Stop button
immediately.
• Turn on the treadmill. With the treadmill speed between 3-4mph, stand behind the treadmill and
watch the movement of the running belt. DO NOT STAND ON THE TREADMILL AND DO NOT
TOUCH THE TREADMILL WHILE PERFORMING THIS PROCEDURE. As you watch the running belt,
make sure that the belt runs without moving from one side to the other and that the belt is centered
between the side rails.

If the running belt is not tracking properly, follow the procedures below:
• If the running belt tracks to the left, turn the left roller bolt clockwise 1/4 of a turn, keeping the belt
tension in mind. Over-tightening the running belt may cause damage to the running belt and roller
bearings.
• If the running belt tracks to the right, turn the right roller bolt clockwise 1/4 of a turn, keeping the belt
tension in mind. Over-tightening the running belt may cause damage to the running belt and roller
bearings.
