Introduction and General Information
3A2091B 7
Introduction and General Information
Introduction
This manual and those supplied provide pre-setup
requirements, parts lists, setup, operation, and mainte-
nance instructions for the RoadLazer RoadPak
Tow-Behind System. This manual includes instructions
for a 2-pump system. For 1-pump systems, all parts
remain the same with the exception of plugged ports for
missing pumps and hoses.
General Information
The Tow-Behind System is attached to a vehicle and is
used to apply up to two stripes in one or two colors with
glass beading.
The Tow-Behind System consists of a Programmable
Skipline Controller, Displacement Pumps, two Paint
Spray Guns, and two Bead Spray Guns.
Programmable Skipline Controller
The Programmable Skipline Controller consists of the
control box and a 30 ft (9.1 m) cable. It is the main con-
trol for the Tow-Behind System and turns the spray guns
and accessories on and off.
Simple Guide System
The Simple Guide System provides the user with a
pointer for alignment on either the left or right side of the
vehicle.
RoadView™Camera System (optional)
The RoadView Camera System provides the user with
video of a bore sight view for alignment on either the left
or right side of the tow vehicle. The system consists of a
9 in. monitor, interfacing cables, video camera and
mounting bracket.
RPS 2900 Hydraulic Pumps
The RPS 2900 Hydraulic Pump supplies paint to the
spray guns. There are two displacement pumps. Two
displacement pumps allows the user to have a two-color
system.
Paint Spray Guns
The Paint Spray Guns are pneumatically triggered to
spray paint stripes when commanded by the Program-
mable Skipline Controller.
Bead Spray Guns
The Bead Spray Guns are pneumatically triggered to
spray reflective materials when commanded by the
Programmable Skipline Controller.

Pre-Setup Requirements
10 3A2091B
Pre-Setup Requirements
Tow Vehicle Requirements
•Tow vehicle with minimum wheel base (front to back)
of 130 in (330 cm).
•Tow vehicle with minimum rated payload capacity of
3500 lb (1588 kg). NOTE: Tongue weight (TW) of
Tow-Behind System is 1000 lb (454 kg).
•Tow vehicle with minimum rated capacity of 7500 lb
(3402 kg) gross trailer weight (GTW)
•Tow hitch with minimum rated capacity of 750 lb
(340 kg) TW, 7500 lb (3402 kg) GTW.
•Warning lights and/or sign board per federal, state,
and local regulations. Reference Part IV of the
Manual on Uniform Traffic Control Devices (MUTCD)
by the U.S. Department of Transportation, Federal
Highway Administration, or equivalent regulations for
your region.
•Securing device for paint supply containers.
•Standard trailer light connector.
•I/O cable access from the tow vehicle cab to the
RoadLazer.
Hitch Requirements
Have a DRAW-TITE®Class IV Ultra-Frame tow hitch (or
equivalent hitch with a 7500 lb (3402 kg) GTW rating and
3 in. x 3 in. (7.6 cm x 7.6 cm) square cross tube) installed
on your vehicle (reference DRAW-TITE part no. series
419XXX). NOTE: Tow hitch not supplied by Graco.
Choose a ball mount that allows the Tow-Behind System
to travel level to the ground with an average payload. A
recommended option is two DRAW-TITE adjustable 2 in.
(5 cm) ball mounts. The ball mount must have a 2 in. x 2
in. (5 cm x 5 cm) insert with at least a 1 in. diameter ball
mount hole. The ball mount hole and shank diameter
must match. The ball mount must have a rating of at least
5000 lb (2270 kg) GTW, 5000 lb (2270 kg) TW.
Receivers
Two Graco clamp-on receivers must be mounted 36 in.
(91 cm) on center on the installed DRAW-TITE Class IV
Ultra Frame Hitch. See Hitch Receiver Kit for mounting
instructions, pages 11 and 12.
Paint Drum Bracket
It is recommended that the paint drums be secured with a
paint drum bracket. Graco does not provide a paint drum
bracket with the Tow-Behind System.
Programmable Skipline
Controller
The Programmable Skipline Controller must be installed
in the cab of the tow vehicle. Select a position for ease of
operation. This controller connects to the RoadPak with
an I/O cable, so there must be cable access from the tow
vehicle cab to the RoadPak. See manual 3A1215.
Paint drums are heavy and could shift from side to side
when the tow vehicle is cornering. The paint drums
could fall from the vehicle and cause serious injury.
Secure the drums when the vehicle is moving.
