IV. WHEELCHAIR USE & CONFIGURATION
BB. Hemi Wheel Lock
Identify Master (Drive) Side and Follower Side
The master (drive) side has the wheel lock with the handle for activating the brake. In Fig. 43, the
master (drive) side is shown on the right side of the chair.
Adjusting the Locks (See Fig. 44)
1. Ensure the wheel lock mount is loose enough to move freely.
2. Set the wheel lock assemblies into the locked position with the knurled bar barely contacting
the tire.
3. With the bolts loosened, slide the assemblies toward the tires in 1/4" increments until the
chair can be lifted by the wheels with locked tires without the wheels rotating.
4. Verify the master lock assembly wheel lock can enter the over-center position when in the
locked position and the follower lock assembly wheel lock can return to the unlocked
position.
NOTE: Some configurations such as spoke wheels with pneumatic tires may show initial
interference with the follower assembly. To fix, move the threaded adjustment on the cable
rearward which allows you to shift the wheel lock forward while retaining the same locking
force.
5. Tighten the bolts that connect the master and follower lock assemblies to the wheel lock
mounts to 50 in/lbs using a 4mm Allen wrench.
6. Fully tighten the bolts connecting the wheel lock assemblies to the chair frame.
7. The threaded adjustment on the follower side should be set so the follower side linkage does
not bottom out.
