Operation
Harbor Freight Tools recommends that the Battery Cut-Off Switch be
installed by a professional technician.
Mounting
1. The Battery Cut-Off Switch (1) must be securely mounted using both mounting holes
before use.
2. It must be mounted in a location where:
a. it will be accessible.
b. it will have ample clearance for the key.
c. it will be away from any hot or metallic parts of the engine.
d. it will not encounter interference from nearby objects.
e. the positive cable (for negative ground vehicles), or negative cable (for rare
positive ground vehicles) can be safely routed to.
3. Only install this unit when the negative clamp is disconnected and insulated from the
battery terminal.
Warning!! If the terminal on the Battery Cut-Off Switch comes in contact with a
grounded piece of metal, serious damage (including explosion and fire) to the
vehicle/battery may occur.

Usage
1. To allow the battery to start and run your vehicle, insert the Key (2) and turn it, as
shown in Assembly Drawing below.
2. When you want to cut off the battery and keep the vehicle from starting, remove the
Key (2). This enables the Cut-Off Switch.
Note: When you enable the Cut-Off Switch by removing the Key (2), your battery will disconnect
and most clocks will stop operating and other preset functions may be erased.
Check that the battery is truly disconnected (try to start the engine) every time
BEFORE leaving the vehicle. It is the responsibility of the vehicle’s owner to
verify that this unit is disconnecting the battery properly.
