Adjust Pointer
Fig. 6
1. Adjust length of crossbar frame (2) so pointer is
approximately in line with RoadLazer striping gun
when wheel arm and pointer arm are parallel to
each other. Tighten crossbar frame
thumbscrews (20).
2. Adjust pointer height so two or three links of
pointer chain drag on ground.

NOTE: Minimum turn radius is a function of distance between pointer and striping gun. If you use the
video system, you can accurately use the pointer on a smaller radius by mounting the extension arm to
the undercarriage of the truck; thus, getting the pointer closer to the striping gun. You will also have to
move the camera back.

3. Use the following table to determine proper pointer
arm length (d in Fig. 6). Use the Mounting
Distance value from the table that is nearest your
truck dimension.
NOTE: If d ends up being less than 26 in.
(660 mm), remove pointer extension arm (6), and
cut off 1 to 6 in. (25 to 150 mm) with hack saw so
you can slide it farther into pointer arm (5). Pointer
arm and extension arm are shown clearly in
Fig. 10 on page 9.
