PAGE 2 of 6 

U.S. Design Patent No. D937,344 S 

  Intended for use by adults only. 

  During and immediately after use, avoid touching any part of the compressor with bare hands as it is very hot 

during such periods. 

  Avoid sounding the air horn when in close range to your ear(s) or the ear(s) of others. 

  Avoid use of product near flames, explosive materials, aerosol products or oxygen devices. 

  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 excessive 
shaking. Do not attach the horn to any plastic or other flexible material. 

  Using the bracket as a guide estimate and mark the positions for the holes and then perforate to size using a 

drill. 

 

Use the provided mounting hardware to fasten the horn.

 

 

AIR LINE INSTALLATION 

  Using the provided 3/8" OD air line, 

cut the size needed. 

  Push hose into the push to connect 

TEE fitting located in the top of the 
horn. 

  Connect the other end of the air line 

to the fitting on your air supply. 

  If you need to disconnect the air line 

from the solenoid pull away the air 
line while pushing the plastic part of 
the pneumatic fitting.
