Warnings
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.
WARNING
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.

WARNING
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 from distributor or retailer.
•
Do not leave the work area while equipment is energized or under pressure. Turn
off all equipment and follow the Pressure Relief Procedure when equipment is
not in use.
•
Check equipment daily. Repair or replace worn or damaged parts immediately
with genuine manufacturer’s replacement parts only.
Warnings
•
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 EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the
eyes or on skin and cause serious injury.
•
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, tubes, and couplings daily. Replace worn or damaged parts immediately.
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.
•
Many other fluids may contain chemicals that can react with aluminum. Contact
your material supplier for compatibility.

Warnings
WARNING
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on
skin, inhaled, or swallowed.
•
Read MSDSs to know the specific hazards of the fluids you are using.
•
Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when
in the operating area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This 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.

Gun Selection
HVLP Guns
An HVLP gun is a high transfer efficiency gun
that limits the air pressure at the air cap to
10 psi (0.07 MPa, 0.7 bar) maximum. In some
areas, an HVLP gun is required for compliance
with environmental standards. See the Air Cap
chart, page 11, for maximum inlet pressure.
Proper Needle/Nozzle Selection
The spray gun's needle/nozzle kits range in
size to provide different fluid flow rates. As a
general guideline, use the fluid nozzle that will
give the required flow with the needle fully triggered at a fluid pressure of 5–20 psi
(0.035–0.14 MPa, 0.35–1.4 bar).
•
For low flow rates or light viscosity fluid,
select the smaller nozzle sizes.
•
For high flow rates or high viscosity fluid,
select the larger nozzle sizes.
•
For abrasive fluids, the gun models with
tungsten carbide needle tip and nozzle are
recommended.

LVMP Guns
An LVMP gun is a high transfer efficiency gun
that has been tested to have a transfer efficiency greater than or equal to HVLP guns. In
addition, the LVMP air cap consumes much
less air than the HVLP air cap. Graco LVMP
guns have no restrictions on air cap pressures.
Conventional Guns
A conventional gun has excellent atomization
and high production rates typically with some
reduction in transfer efficiency.
HiTEch Guns
A HiTEch gun is a high transfer efficiency gun
with excellent atomization. Graco HiTEch guns
have no restrictions on air cap pressures.

Installation
Installation
This spray gun can spray most coatings or finishes currently being used for small component plastic, wood and metal finishing
applications, while easily operating from paint
delivery systems, such as pressure pots or
remote pumps for production line operation.
The air regulator must have a minimum air flow
capacity of 30 scfm at 100 psi (0.7 MPa,
7.0 bar) air pressure.
Ventilate Spray Booth
To prevent hazardous concentrations of toxic
and/or flammable vapors, spray only in a properly ventilated spray booth. Do not operate the
spray gun unless ventilation fans are
operating.
Configure Gun and Manifold
Guns with Manifold
See FIG. 1. The gun is shipped with a fluid plug
(25). To use the gun in a circulating system, do
not install the plug. In a non-circulating system,
install the plug as shown to minimize flush
time.
1. Connect the fluid supply line to one fluid
port fitting and the fluid return line to the
other. The manifold fluid ports are
reversible.
2. Install the gun on the manifold, using the
two screws. Torque the screws evenly to
50 in-lb (5.6 N•m).
1
Do not install when used in circulating systems.
•
Check and follow all national, state, and
local codes regarding air exhaust velocity
requirements.
•
Check and follow all local safety and fire
codes.
