Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire
and explosion:
• Use equipment only in well ventilated area.
• Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable and can
ignite or explode if spilled on hot surface.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths
(potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are
present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.

Introduction and General Information
Introduction and General Information
Introduction
This manual and those supplied provide pre-setup
requirements, parts lists, setup, operation, and maintenance 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 control 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 Programmable Skipline Controller.
Bead Spray Guns
The Bead Spray Guns are pneumatically triggered to
spray reflective materials when commanded by the
Programmable Skipline Controller.

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
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.
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
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.
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.
