Running Deck
The following procedure will help determine and properly adjust the deck bumpers.
Symptom:
Running deck squeaks when running.
1. When properly located, the side bumpers (two on each side) bear against the
delrin rods in the frame rails. The rear bumpers bear against the steel posts at
the end of the frame rails. If the bumpers are not located so they bear against
the rods as described, the running deck may shift to one side or the other
during use. This allows the rear edge of the deck to rub against the steel post.
This causes a high-pitched squeak as the user runs on the treadmill.
2. To determine if a deck has the bumpers properly located, look under the end
cap/finger guard to see if the bumpers on the end of the deck bear against the
steel posts. A problem definitely exists if the bumpers are to one sode of the
steel posts and the edge of the deck is bearing against the posts.
3. Remove the screws securing each of the four delrin rods and pull them out.
Look through the hole in the frame to see if the running deck bumper is
adjacent to the hold, such that it would bear against the delrin rod if it was
reinstalled in the hole. If all bumpers are properly located, replace the delrin
rods and examine the treadmill further for the other causes of squeaks. If one
or more bumpers is misalign, follow the procedure given below.
