3.  Place the calibrated inclinometer against the front surface of the radar unit so that it is in the same orientation as it was on the frame rail.
4.  Verify that it displays 0° (+/- 1.5°)
5.  If no adjustment is necessary, proceed to next page.

BRACKET REMOVAL

The camera must be removed prior to this procedure. The preferred method for removing a bracket idealy requires two technicians. Using a heat-gun, one of the technicians gradually applies heat to the outside of the windshield at the location of the adhesive, while the other gently applies a prying force to the bracket while being careful not to damage the windshield. As soon as the ideal temperature is reached, the bracket will release. Allow the windshield to completely cool down before cleaning the glass and installing a replacement bracket. When replacing brackets, use only replacements with the same part number or a direct superceding replacement number supplied by Bendix or the OEM.Ifyou have questions, Contact the Bendix Tech Team at 1-800-AIR-BRAKE (1-800-247-2725), option 2. NOTE: Some OEMs may offer the windshield with the bracket pre-installed. Contact the dealer for more information.
