To make switch tamper-proof, selfshear
type screws are used. Their heads
are sheared off when installed so that

easily removed.

lock in accordance with the following
instructions.
Break self-shear type screws with a
drill or other proper tool, then remove
the steering lock from the steering
lock clamp.
When installing a new steering lock,
be sure to tighten new self-shear type
screws until their heads shear off.
