  Be sure to pump nothing other than atmospheric air. 

  It is important to determine the maximum air pressure for any tool or attachment before using it. 

  Air sprayer or nozzle should always be pointed away from any part of the body. 

  The compressor has Thermal Overload Protection, if this protection activates, cut off the source of power and let 

the unit cool down for about 30 minutes. This will reset the system and allow you to safely resume use of the air 
compressor. 

  Make sure your battery ground is detached before you begin. 

  Set the horn up for use only in areas with adequate ventilation. 

  Employ equipment for eye protection during drilling operations. 

  Ensure that your air system has no pressure before you begin. 

 

 

 

 

PLANNING YOUR INSTALLATION 

 

Before beginning the installation, determine each component’s spot. 

  Confirm you have the proper length of airline and wire. 

  Power wire to compressor should be kept short. 

  To power up the air compressor, make sure you use a 12-gauge wire or thicker. 

HORN 

MOUNTING 

  Identify a suitable area for mounting, preferably an unobstructed sheet-metal surface like the frame or body of 

the vehicle so as to provide a firm platform which will help protect the horn from damage due to shaking. 
Never attach the horn to any plastic or other flexible material. 

  Mark the spots for the holes with the bracket and then drill. 

 

The mounting hardware should be used to fasten the horn.

 

 

AIR LINE INSTALLATION

 

  On one side of the included 1/4" OD air line, attach the compression nut and force the air line upon the male 

inlet fitting which is found on the electric solenoid valve. 
 

 

 

  Pass the brass nut through the inlet fitting and fasten. 

 

Take the air line’s other side and place the compression nut of the air tank fitting on it. Force the air line onto 
the male fitting of the tank and then fasten the compression nut. 

WARNING

: Avoid over tightening.
