J. ADJUSTING THE “SQUEEZE”

The term “squeeze” refers to the position of the pivoting seat frame relative to four factory preset positions on the rear frame uprights. The squeeze is adjusted by raising or lowering the seat frame to one of the four positions (ref- erenced as 1-4 from top to bottom). Changing the amount of seat squeeze not only adjusts the comfort level of the user, but also raises or lowers the center of gravity-thereby affecting the chair’s relative performance. Consult your therapist and dealer to determine the squeeze and seating position that’s best for you.

1.Remove the Rear Wheels

2.Remove the Rear Quick-Release Clamps (Figs. A and B)

a.Lift up on the release lever, thus loosening the clamp.

b.Unscrew the locknut from the opposite end of the clamp and remove it from the threaded por- tion of the clamp.

c.Pull the remaining portion of the clamp out and away from the locating hole in the rear anodized frame component.

3.Adjust the Rear of the Seat Frame

After removing the clamps, move the rear of the seat frame up or down to one of four preset positions as desired. Note that since the backrest assembly moves with the pivoting seat frame, it may require readjust- ment after this procedure. See the section on Adjusting the Backrest (pg. 34).

*The clamp shown in the drawings above should remain on the inside of the chair.

4. Reinstall the Rear Quick-Release Clamps
a. Working from the inside of the chair, insert the
threaded portion of the clamp through the
anodized frame component and the appropriate
adjustment hole in the rear upright
of the frame.
b. Push the clamp through until it rests against
the anodized frame component. Be sure that the
clamp’s square portion engages the square open-
ing in the spacer & washer. Improper alignment	Figure C
may cause the clamp to extend from the frame
somewhat, causing improper clamping.

CAUTION– An unexpected loosening of the clamp may result.

c. With one hand on the lever, install the locknut onto the threaded end of the clamp with your other hand. Work the lever up and down as you tighten the locknut, until you feel sufficient ten- sion to clamp it firmly into place. The black safe- ty lock button will engage and click into place. If the lever will not close, or will do so only with excessive pressure, loosen the locknut slightly until the clamp can be locked into place with relative ease. Listen for the click to be sure that the safety lock is secure.

d. Test the clamp by pulling up on the release lever without engaging the black safety lock button. The clamp lever should not release. Repeat

this procedure for the other clamp.

CAUTION– Never operate this wheelchair with the clamp assemblies partially or improperly secured.
