Wheel Locks
Installing Wheel Lock Clamps
1. The wheel lock assemblies with the wheel lock bars are mounted onto the chair using the wheel lock
clamps (C & D). There are two types of wheel lock clamps that are shown below. Install hardware with
the wheel lock bar and chair frame in position using a 5mm Allen wrench and a 6mm Allen wrench.
Once installed, ensure wheel lock engages at least 1/8" into tire and locks properly prevent the chair
from moving when engaged.
NOTE: Always tighten wheel lock hardware as shown in the image below. This prevents
overclamping on one set of hardware which can lead to binding of the fasteners and increased
diffculty in removal.
