WARNING
If converting from six-inch fork to an eight-inch fork or vice versa, there
are SEAT-TO-FLOOR height adjustments that must be made. A qualified
technician MUST perform these adjustments if this is the case.
Make sure both fork/caster assemblies are the same size BEFORE using
the wheelchair, otherwise injury may occur.

1. Remove the dust cover.
2. Remove the locknut and nylon washer that
secures the fork to the caster headtube.
