IMPORTANT:
To assure the highest level of planning and reliability goes into this installation,
please read this guide in its entirety before attempting any modifications to the vehicle.
1.1 Pre-Installation Preparation
Although your ARB Air Compressor Bracket comes complete with all the step by step
instructions you will need to install it, ARB recommends that you have your ARB Air
Compressor installed by a trained professional. Many ARB distributors around the world
have been fully instructed in Air Compressor installations by ARB, and have gained a wealth
of experience and skill from years of performing similar installations.
Make sure your Air Compressor Bracket kit is the correct model for your application and that
it contains all of the parts listed in section 1.3 below. Also, be sure you have appropriately
equipped yourself with all the necessary tools, parts, materials and knowledge to complete
this installation and minimize vehicle down time (see section 1.4 Tool-Kit Recommendations).
Please refer to your ARB Compressor and Air Locker Operating & Service Manuals for
information on operating, servicing, driving technique, or trouble shooting your ARB Air
Locker(s) if installed.
HINT: Place a mark inside each of the symbols as you complete each step.
It is very important NOT to miss any of the steps!
