VISCO-BACK

Attaching Quick Release Compass Hardware

Parts Included:

1 - Complete Visco-Back Assembly
1 - 5 mm Hex Key
1 - 2.5 mm Hex Key

Loosen the two clamp bolts (A) on both sides using the supplied 5 mm Hex Key. Tighten the clamps onto
the left and right wheelchair canes.

Slightly loosen bolts (B) above and below the triangles on both sides using the 5 mm Hex Key. Slide the
triangles in or out until the wheelchair canes are relaxed.

The triangles adjust in and out to accommodate varying sized wheelchairs. The Visco-Back can fit onto a
wheelchair 1" narrower to 1" wider of the purchased size.

Tip: Make sure the clamps are the same height relative to one another on the canes.
Tip: Make sure the clamps are square to the wheelchair.

Note: The quick release levers may be tight when first actuated, but will loosen after 1-3 times.

Tighten set screw (E) on both sides using the supplied 2.5 mm Hex Key to lock angle rotation. These set
screws intersect with the top bolts and prevents angle rotation.

Triangle Height Adjustment: Make sure the left and right triangles are at the same height relative to one
another on the backrest shell. When triangles appear to be in line, finger-tighten bolts (B) on both sides,
open quick release levers (C), and remove/reinstall the backrest.

Tighten set screw (F) on both sides using the 2.5 mm Hex Key to prevent vertical movement and angular
rotation of the clamps.

The installation of the backrest is complete. Adjustments for depth, angle, height, and spinal curvature

can now be made. The user can be seated during this process.

If the backrest was able to be removed and reinstalled smoothly, no additional height adjustments are
needed. If further adjustments are needed, repeat step 3. Fully tighten bolts (B) when adjustments are
complete using 5 mm Hex Key.

Angle and Depth Adjustment: Loosen the two bolts (D) on both sides using the 5 mm Hex Key. The
backrest can be slid forward/backwards. The backrest can be rotated angularly. Tighten all four bolts
when the backrest depth and angle are adjusted.

IMPORTANT: When installation and adjustments are complete, all bolts should be tightened to a mini-
mum of 85 in-lbs.
