Warnings
3A6285D 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 symbols appear in the body of this
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols
and warnings not covered in this section may appear throughout the body of this manual where
applicable.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may
look like just a cut, but it is a serious injury that can result in amputation. Get immediate
surgical treatment.
•Do not spray without tip guard and trigger guard installed.
•Engage trigger lock when not spraying.
•Do not point gun at anyone or at any part of the body.
•Do not put your hand over the spray tip.
•Do not stop or deflect leaks with your hand, body, glove, or rag.
•Follow the Pressure Relief Procedure when you stop spraying and before cleaning,
checking, or servicing equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses and couplings daily. Replace worn or damaged parts immediately.
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.
•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
43A6285D
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Always wear appropriate gloves, eye protection, and a respirator or mask when painting.
•Do not operate or spray near children. Keep children away from equipment at all times.
•Do not overreach or stand on an unstable support. Keep effective footing and balance at
all times.
•Stay alert and watch what you are doing.
•Do not operate the unit when fatigued or under the influence of drugs or alcohol.
•Do not kink or over-bend the hose.
•Do not expose the hose to temperatures or to pressures in excess of those specified by
Graco.
•Do not use the hose as a strength member to pull or lift the equipment.
•Do not spray with a hose shorter than 25 feet.
•Do not alter or modify equipment. Alterations or modifications may void agency approvals
and create safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death,
serious injury, or property damage.
•Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents.
•Do not use chlorine bleach.
•Many other fluids may contain chemicals that can react with aluminum. Contact your
material supplier for compatibility.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury,
including eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective
equipment includes but is not limited to:
•Protective eyewear, and hearing protection.
•Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.

Setup
3A6285D 5
Setup
Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
1. Turn sprayer OFF.
2. Engage the trigger lock. Always engage
the trigger lock when sprayer is stopped
to prevent the gun from being triggered
accidentally.
3. Turn pressure control knob to lowest
setting.
4. Put drain tube into a waste pail and turn
Prime/Spray valve in PRIME position
(drain) to relieve pressure.
5. Hold the gun firmly to a pail. Point gun
into pail. Disengage the trigger lock and
trigger the gun to relieve pressure.
6. Engage the trigger lock.
7. If you suspect the spray tip or hose is
clogged or that pressure has not been
fully relieved:
a. VERY SLOWLY loosen the tip
guard retaining nut or the hose end
coupling to relieve pressure
gradually.
b. Loosen the nut or coupling
completely.
c. Clear airless hose or spray tip
obstruction. See Clear Spray Tip
Clog, page 8.
Gun Trigger Lock
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection or splashed
fluid, follow the Pressure Relief
Procedure whenever sprayer is stopped
and before sprayer is cleaned or checked,
and before equipment is serviced.
To prevent injury when the gun is not in
use, always engage the gun’s trigger lock
if unit is being shut down or left
unattended.

Setup
63A6285D
Trigger Adjustment
The trigger can be adjusted to different
lengths depending upon user preference.
1. Relieve pressure. See Pressure Relief
Procedure, page 5.
2. Loosen adjustment knob (13c). Use a
flat blade screwdriver or coin if the knob
(13c) cannot be loosened by hand.
Complete one full turn to loosen the
adjustment knob. Three full turns could
result in the adjustment knob falling out.
3. Hold end of trigger (13b) and slide to
desired position.
NOTE: Hold trigger in location shown when
adjusting.

Install Tip and Tip Guard
on Gun
To prevent spray tip leaks make certain spray
tip and tip guard are installed properly.
1. Relieve pressure. See Pressure Relief
Procedure, page 5. Engage trigger lock
(15).
2. Use spray tip (26) to align gasket and
seal (24) in the tip guard (25).
3. Insert tip (26) in guard (25).

mately 12-inches (304 mm) from sur-
face. Move gun first, then pull gun
trigger (13) to spray a test pattern.
4. Slowly increase pump pressure until
coverage is uniform and even (see
sprayer instruction manual for additional
information).
Clear Spray Tip Clog
In the event that particles or debris clog the
spray tip, this gun is designed with a
reversible spray tip that quickly and easily
clears the particles without disassembling the
