GG. 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 downward. 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 stated. 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.
