5. Remove the two aluminum traction strips, located one on each side of running deck. These
are secured by four Allen screws located on top of traction strips.
6. Remove rear treadbelt roller. The roller is secured by two treadbelt tensioning bolts. Once
bolts have been removed, lift out the roller assembly.
7. Remove the two Allen screws which secure the front treadbelt roller. The screws are located
on the side of the Gait Trainer.
CAUTION: When the bolts securing the roller are removed the roller will drop. Be aware that the
!
rollers are heavy.
ATTENTION: Si les boutons de sécurité du rouleau sont retirés, le rouleau chutera. Ne oas oubli-
!
er que les rouleaux sont lourds.
8. Remove the running deck. This is done by lifting from the side of the deck and raising the
deck two inches before sliding it out. The running deck is two-sided and can be flipped over
and reused once.
9. To remove the treadbelt seven support brackets must be removed. These are comprised of three
angle iron brackets attached by securing nuts, and four running deck support bars secured by
Allen screws. Once all support brackets are removed the treadbelt can be removed.
10. Tension treadbelt and adjust tracking after you reassemble the Gait Trainer. (See Treadbelt
Adjustment procedure.)
Treadbelt Adjustment
Although the Gait Trainer incorporates the "Exact Track System," occasional belt adjustments are
still necessary for correct tensioning and tracking.
Tension Adjustment
CAUTION: Before testing treadbelt tension as described below, turn the Gait Trainer OFF and
!
unplug the system. Moving parts on the Gait Trainer can cause serious injury. Do not attempt to
determine treadbelt tension while the belt is moving.
ATTENTION: Avant de tester la tension du tapis selon la procédure décrite ci-dessons, méttre le
!
tapis à l'arrêt et déconnecter le câble secteur. Certaines piéces du tapis peuvent entrainer des
blessures graves. Ne jamais essayer de déterminer la tension sur le tapis pendant que ce dernier est
en mouvement.
The need for tension adjustment is indicated by uneven belt speed or the belt stopping suddenly
upon foot impact. Properly tensioned, the treadbelt will allow the user to slip a hand snugly under
the center of the belt.
Treadbelt tension is adjusted by tightening or loosening the two hex-head, 9/16, bolts at the end of
the Gait Trainer frame. The bolts should be adjusted in 1/4-turn increments, exactly the same
amount, in the same direction. Turn both bolts clockwise to tighten the belt. Turn both bolts coun-
terclockwise to loosen the belt. Failure to turn both bolts equally may affect tracking. One quick test
is to apply hand heel strikes and observe if belt momentarily stops. If belt speed remains constant,
this indicates belt is tight. If belt hesitates during heel strikes, additional tightening is required. To
check over tightening, set Gait Trainer to .5 mph and, while holding rail, resist until belt stops. If
drive roller continues to rotate with the belt stopped, further adjustment is not necessary. If drive
roller stops when belt is stopped, belt is too tight. Loosen belt and recheck.
