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.

is fully extended to end of main beam (C), and
front pointer system crossbar frame (2) is
extended, as shown in Fig 6.
2. Drive truck forward along an existing straight
line (B), and get pointer and striping gun visually
lined up along the line, as shown in Fig 6.
Focus Camera
1. Loosen two set screws (A) that are on both sides
of lens. See Fig. 7.
2. Place an object that is easy to focus approximately
25 ft (7.6 m) in front of camera.

System Setup
Reference numbers in parentheses in the text refer to
numbers in Parts section of this manual.
Align Camera
1. See Fig. 9. Loosen clamps (56) securing video
camera bracket, and slide camera extension arm
out until camera is centered directly over reference
line. Tighten clamps.
2. See Fig. 8. Loosen nut (214) and clamp (B), and
set camera height and tilt-angle to include pointer
chain (24) and natural horizon in video monitor
screen. Tighten nut and clamp.
Check Pointer Alignment
1. Check video monitor screen for proper pointer
alignment. When pointer and camera are properly
aligned, pointer is vertical and visually splits head
of pointer arm pivot bolt (13), as shown in Correct
Pointer Alignment photo in Fig. 9.
NOTE: If pointer is off line, see Fig. 10: Remove
clevis pin (9) from one end of threaded rod (7), and
loosen nut (8) at end from which you removed
clevis pin. If pointer was toward truck, turn clevis
fastener (10) in to shorten rod. If pointer was
away from truck, turn clevis fastener out to
lengthen rod. Each turn of clevis fastener adjusts
pointer approximately 1/4 in. (6 mm).
2. When the pointer is properly aligned, mark all
extension points with a permanent marker for
future reference. Extension points are marked
with a star (L) in Fig. 6 and Fig. 8.

Painting
Using Front Mechanical Pointer System without Video
Guidance System requires that you drive with your
head out of driver’s-side window to align pointer.
Using the two systems together improves ease of
painting and accuracy of lines. Follow these guidelines
when you use Front Mechanical Pointer System and
Video Guidance System together:
DWhether painting straight or curved lines, keep
pointer image on video monitor screen on the line,
and the striping guns will follow. As shown in
Fig. 13, pointer floats left or right when truck turns.
DFor accurate straight lines, line up pointer image on
more distant reference points, which are closer to
top of pointer (and top of video monitor screen).
See Straight-Line View below.
Straight-Line View
DFor accurate curved lines and transitions, such as
when around town, line up pointer image on closer
reference points, which are closer to bottom of
pointer (and bottom of video monitor screen). See
Curved-Line View below.

1. Align truck and camera with known straight line.
2. Lower gun carriage to ground, and align striping
guns with line.
3. Drive down straight line, and stop when pointer
chain reaches start of line.
4. Get out of truck, and precisely measure distance
from start of line to striping gun.
5. Enter figure into system delay menu.
System is ready to start striping.
6. Fine tune delay figure if system is continually off
the mark.

Maintenance
Front Mechanical Pointer System Maintenance
Fig. 16
NOTE: Wheel and pivot points use same nuts,
washers, spacers, seals, bearings, and bolts. For
wheel only, bearings and seals are assembled
internally and not called out as separate parts on
page 18.
Lubricate Wheel Axle
Grease axle bolt (13) monthly. Do not over-grease or
inject grease too rapidly, because seals might get
pushed out. Axle bolt may require more frequent
greasing during periods of heavy use.
Lubricate Pivot Points
Grease pivot bolts (13) yearly. Do not over-grease or
inject grease too rapidly, because seals (29) might get
pushed out. Bolt may require more frequent greasing
during periods of heavy use.
Torque Axle Nut and Pivot Point Nuts
Retorque nuts (17) yearly. For proper torque, tighten
nut up to the point where washer (16) begins to
compress, then tighten an additional 1/4 turn.
