SAFETY LOCK 4

ANTI-THEFT DEVICE

A CONTROLLER THAT PERMITS
UNATTENDED ENGINE OPERATION
BUT PREVENTS UNAUTHORIZED USE
OF VEHICLE

PERMITS ENGINE TO RUN WITH THE
IGNITION KEY REMOVED

ENGINE STOPS AND CANNOT BE
RESTARTED IF ATTEMPT IS MADE TO
DRIVE AWAY

MODEL #091-160

This simple, low cost controller bypasses the ignition switch when activated by the closure of a momen­tary switch. The operator may then remove the ignition key without shutting the engine down. Move­ment of the vehicle is prohibited by interlocking the SAFETY LOCK 4 with the brake light switch, a
neutral safety switch on the gearshift or a parking brake operated switch. Operating any one of these
will cause the relays in the SAFETY LOCK 4 to drop out and interrupt the ignition circuit to stop the
engine. The authorized operator need only insert the key and turn on the ignition to operate the vehicle.
With the key in the lock and turned on, the ignition circuit is completed as normal and the opening of the
SAFETY LOCK 4 relays has no effect on engine operation.

The SAFETY LOCK 4 contains 4 relays to permit energizing 3 auxiliary circuits in addition to

the ignition switch bypass.
