AIRSTREAM INTERNATIONAL TRAILER
In THE EVENT OF AN ACCIDENTAL SEPARATION of the tow vehicle and the trailer, the BREAK-
AWAY SWITCH will set and lock the trailer brakes for a sufficient length of time to stop the trailer. The
switch is activated when the wire attached to it and to the tow vehicle pulls out the small pin in the front of
the unit. THIS PIN SHOULD BE PULLED OUT, LUBRICATED WITH LIGHT HOUSEHOLD
OIL, AND REPLACED EVERY 90 DAYS.
To prevent corrosion within the breakaway switch, pull the switch's pin straight forward and spray the
inside of the switch through the hole with an electric contact cleaner (such as Spra-Kleen) and re-insert pin.
A drop of light household oil on the groove near the base of the pin will allow the pin to operate freely.
WHEN THE TRAILER IS CONNECTED TO THE TOW VEHICLE, THE BREAKAWAY SWITCH
LOOP SHOULD BE ATTACHED TO THE PERMANENT FRAME OF YOUR HITCH. When
disconnecting the trailer from the tow vehicle remove wire loop from the frame. DO NOT REMOVE PIN
FROM SWITCH BECAUSE THIS WILL APPLY THE TRAILER BRAKES.
WARNING
: Do not use breakaway switch for parking brake.
