IX. DEALER SERVICE & ADJUSTMENT
BB. ATTENDANT WHEEL LOCK INSTALLATION
1.
Remove wheels from chair.
2.
Attach Mount bracket/cable assembly to axle strut tube using 1/4" x 1-3/4" bolt (item 1) with nut and washers.
3.
If push-to-lock wheel locks are already installed, remove the push-to-lock assemblies by removing the M6 bolts (item 2) and adjustment nuts (item 3),
leaving the slide plates mounted on the chair, and go to step 5. If there are no wheel locks mounted already, proceed with step 4.
4.
Attach Wheel Lock Slide Plates to Roller Assembly on each side of the chair using 1/4" hex bolts (item 4) and Mounting Block (item 5). If axle of rear
wheel is above the base frame tube, orient the slide plates upward. If the axle of the rear wheel is below the base frame tube, orient the plates down-
ward. Plate may be flipped forward or reversed as needed for different wheel sizes.
5.
Attach the left and right Remote Lock Assemblies (item 6) to the slide plates using the Attendant Wheel Lock Spacer Blocks (item 7), M6 x 60 screws
(item 2), lock washers (item 8), and Wheel Lock Adjustment Nuts (item 3). The adjustment nuts marked “R” and “L” are to be mounted to the right and
left side of the chair respectively. The smaller protruding oval shape on the nuts should slide inside of the slot in the slide plate. Do not tighten bolts.
Slide the Remote Lock Assemblies as far forward as they will go.
6.
Re-install wheels and slide the Remote Lock Assemblies rearward until the friction block of the remote lock is approximately 1/4" (6mm) away from the
tire when unlocked. If the lock cannot be adjusted to this position, you will need to adjust the position of the slide plate until it can be adjusted as stat-
ed. Once remote locks are properly positioned, tighten bolts.
7.
Attach cables to Remote Lock Assemblies by sliding the stud at the end of the cable into the slot in the Remote Lock Assembly. Pull back on the cable
sheath and slide the end of the cable sheath into the pocket on the Attendant Wheel Lock Spacer Block (item 3) as shown. Be sure that the cables are
routed away from all moving parts. Attach the cables into place on the chair with zip-ties provided.
8.
Adjust the cable adjustment screws (item 9) as necessary to ensure that the wheel locks can get to their fully extended position when the pedal is
engaged. Position of the Remote Lock Assembly may need to be fine tuned to optimize the force needed to engage the pedal, depending on tire type. If
excessive force is needed to engage the pedal, cable life may be reduced. Once proper adjustment is attained, lock cable adjustment screw in position by
tightening jam nuts against mounting block.

both sides
