Procedure:
1) Turn off the power to the treadmill and remove the power cord from the wall outlet.
) Remove the motor cover.
3) Unplug the motor wires from the motor control board.
4) Loosen the attachment nuts (A) holding the motor bracket to the frame. (Figures 5 & 6)
5) Tighten bolt (B) to increase tension on drive belt. (Figures 5 & 6)
6) Tighten or loosen bolt (C) to straighten motor bracket and ensure that the pulleys on the motor and front
roller are properly aligned. (Figures 5 & 6)
7) Tighten the two motor bracket attachment nuts (A) when finished. (Figures 5 & 6)
8) Verify the proper tension on the drive belt. Using a timing belt tension gauge, the proper tension should be
between 65 to 75 lbs. If a timing belt tension gauge is not available, the drive belt should have approximately 3/8 of
inch deflection. If the drive belt tension is not set properly, loosen the motor attachment bolts and adjust.
MAINTENANCE
Before continuing, it is a good idea to weigh down the treadmill deck to pre-
vent the treadmill from springing up. Removing the weight of the motor will
significantly reduce the weight in the front end of the treadmill.
