Using a 9/16” socket wrench with a 3” extension, insert the two screws that fasten the front roller B.

Using a 3/4” socket wrench, tighten each rear roller bolt evenly, making sure not to tighten either A.
bolt too many turns before moving to the other bolt. NOTE: Do not overtighten the belt. Follow the
Tension and Center the Belt procedure located in the Preventive Maintenance chapter.
Motor Brushes
NOTE: Motor brushes are wear items that will periodically need to be replaced. Both drive motor brushes
must be replaced as a pair. This will ensure even commutator contact and brush wear. Therefore,
always measure both brush lengths to determine whether you should replace the pair. Check
both brushes for cracks or chips.
NOTE: When “Err9” appears on screen it indicates excessive motor brush wear. The treadmill will run
100 miles (161 kilometers) longer and then be inoperable until brushes are replaced.
! CAUTION: If the drive motor is warm wait until it is cool to the touch before proceeding.
The inside components of the drive motor may be hot.
! WARNING: Keep the motor dry. Do not get the inside of the motor wet.
NOTE: If you are checking and/or replacing the motor brushes follow steps 9-13. If not, skip to step 14.
! WARNING: Wait until the armature LED is off before removing the motor brush covers.
9. Check the armature LED.
Observe the “armature LED” on the lower board (labeled ILT4). A.
After the armature LED goes off proceed to step 10.B.
