For the application of architectural paints and coatings -
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 hazard symbols refer to procedure-specific risks. Refer back to these
Warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
WARNINGS
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 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.
• Do not spray without tip guard and trigger guard
installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when
you stop spraying and before cleaning, checking, or servicing equipment.
FIRE AND EXPLOSION HAZARD
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.
• 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.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop
operation immediately. Do not use equipment until
you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
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.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s
warnings. For complete information about your material, request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or
damaged parts immediately with genuine manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call
your distributor for information.
• Route hoses and cables away from traffic areas,
sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull
equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride,
other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such
use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when
operating, servicing, or in the operating area of the
equipment to help protect you from serious injury. This
equipment includes but is not limited to:
• Protective eyewear and hearing protection
Gloves, clothing and respirator as recommended by the

will have to cut the black air
hose to length desired.
ti13317a
2. Attach fluid hose.
Follow this Pressure Relief Procedure whenever
instructed to relieve pressure, stop spraying, check or
service equipment, or install or clean spray tip.
1. Turn OFF power and turn sprayer pressure control to
lowest pressure setting.
3. See Setup instructions in
sprayer operation manual
(313316).
ti13318a
2. Hold gun against side of grounded metal flushing
pail. Trigger gun into pail to relieve pressure.
If you suspect spray tip or hose is clogged or that
pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen tip guard retaining
nut or hose end coupling to relieve pressure gradually,
then loosen completely. Clear hose or tip obstruction.

Operation
Note: The following instructions are for guns used with
Graco FinishPro Sprayers. See the sprayer instruction
manual 313316. If you are using a different sprayer, see
your equipment instruction manual.
1. Unlock trigger lock.
2. Be sure the arrow shaped tip (B) faces forward

3. Hold gun perpendicular and approximately 12 in.
(304 mm) from surface. Move gun first, then pull gun
trigger (D) to spray a test pattern.
4. Do not spray in an arc. This causes an uneven fluid
coat. Spray in a path parallel to the surface, with a
50% overlap, to obtain an even fluid coat.
