Warnings
3A4637A Operation, Repair, Parts 3
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation
point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these sym-
bols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard sym-
bols and warnings not covered in this section may appear throughout the body of this manual where applicable.
SKIN INJECTION HAZARD
High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that
injection occurs, get immediate surgical treatment.
• Do not aim the gun at, or spray any person or animal.
• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with any
part of the body.
• Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.
• Use Graco nozzle tips.
• Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while spraying,
follow the Pressure Relief Procedure for turning off the unit and relieving the pressure before removing
the nozzle tip to clean.
• Equipment maintains pressure after power is shut off. Do not leave the equipment energized or under pres-
sure while unattended. Follow the Pressure Relief Procedure when the equipment is unattended or not
in use, and before servicing, cleaning, or removing parts.
• Check hoses and parts for signs of damage. Replace any damaged hoses or parts.
• This system is capable of producing 3300 psi. Use Graco replacement parts or accessories that are rated
a minimum of 3300 psi.
• Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.
• Verify that all connections are secure before operating the unit.
• Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the controls.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or solvent
flowing through the equipment can cause static sparking. 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 sparking).
• Ground all equipment in the work area. See Grounding instructions.
• Never spray or flush solvent at high pressure.
• 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.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they are
anti-static or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment until you
identify and correct the problem.
• Keep a working fire extinguisher in the work area.

Warnings
43A4637A Operation, Repair, Parts
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.

Moving parts can pinch, cut, or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow
the Pressure Relief Procedure and disconnect all power sources.
ENTANGLEMENT HAZARD
Rotating parts can cause serious injury.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Do not wear loose clothing, jewelry or long hair while operating equipment.

Grounding Procedure (For Flammable Materials Only)
83A4637A Operation, Repair, Parts
Grounding Procedure
(For Flammable Materials Only)
1. Position striper so that the tires are not on pave-
ment.
2. Striper is shipped with a grounding clamp. Ground-
ing clap must attach to grounded object. (e.g. metal
sign post).
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
1. Perform Grounding Procedure if using flammable
materials.
2. Set pump switch OFF. Turn engine OFF by pressing
the engine kill switch at the controls, or by moving
the lever on the engine.
3. Turn pressure to lowest setting. Trigger gun to
relieve pressure.
4. Engage the trigger lock. Turn prime valve down.
5. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved:
a. VERY SLOWLY loosen tip guard retaining nut
or hose end coupling to relieve pressure
gradually.
b. Loosen nut or coupling completely.
c. Clear hose or tip obstruction.
This equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashed fluid and moving parts, follow the Pressure
Relief Procedure whenever sprayer is stopped and
before sprayer is cleaned or checked, and before
equipment is serviced.

SPARK PLUG: Use only Briggs & Stratton 491055S or
Champion RC12YC spark plug. Gap plug to 0.030 in.
(0.762mm). Use spark plug wrench when installing and
removing plug.
Front Wheel Alignment:
Align front wheel as follows:
1. Loosen cap screw (114).
2. Position front wheel left or right, as necessary, to
straighten alignment.
3. Tighten cap screw. Push striper and let striper roll
with hands off of striper.
NOTE: If striper veers right or left, repeat steps 1 and 2
until striper rolls straight.

Self-Propelled Drive
The self-propelled drive assists the user in moving the
striper through turf and/or up a grade. The drive can be used
with or without the engine running. Maximum performance
is achieved with the engine running at full RPM.
Power ON/OFF
The drive power switch includes the engine kill function.
1. Ensure the Drive Control switch is in the “N”
position.
2. Press the bottom portion of the Engine Kill/Drive
Power switch to power the drive system.
3. Move the Engine Kill/Drive Power switch to the
middle position to shut off the drive system. Fully
depress the top portion of the Engine Kill/Drive
Power switch to shut off the gas engine.The drive
system is off when the green light on the switch is off.
NOTICE
Running the drive with the engine off, or at a lower than
maximum RPM, may cause damage to the battery from
over-discharging.
NOTICE
Leaving the drive system on when not using, or when
storing the machine, may cause damage to the battery
from over discharging.

Drive Control
The drive control switch on the left handlebar has three
positions to control the engagement of the drive system.
• “N” places the drive in neutral and allows the unit to
be moved manually.
• “D” must be held down to engage the drive and
move the striper forward.
• Cruise keeps the drive engaged, until disen-
gaged by momentarily depressing “D”.
Speed Adjustment
The speed control will vary the speed from 0 to maximum
over the full range of the speed knob. Turning the speed
knob fully counterclockwise will result in no motion, and
turning the speed knob fully clockwise will result in
maximum speed.
Changes in the terrain may require adjusting the speed;
i.e. moving from turf to pavement.
Speed Control
1. With the engine already running, and the drive
system OFF, turn the speed knob fully
counterclockwise to the “0” speed position.
2. Press Cruise on the driver control switch to
engage the self-propelled drive.
