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 lights on or off when flammable fumes are present.
•Ground equipment and conductive objects in work area.
•If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and
correct the problem.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Tech-
nical 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.
•Check equipment daily. Repair or replace worn or damaged parts immediately.
•Do not alter or modify equipment.
•Use equipment only for its intended purpose. Call your Graco distributor for information.
•Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
•Do not use hoses to pull equipment.
•Keep children and animals away from work area.
•Comply with all applicable safety regulations.
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 MSDS’s to know the specific hazards of the fluids you are using.

to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equip-
ment includes but is not limited to:
•Protective eyewear
•Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
•Hearing protection
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.

Setup
•Set shop air pressure regulator (not supplied) according to
paint manufacturer’s recommendation. Do not exceed 50
psi (345 kPa, 3.4 bar).
•Make sure no air restrictions, such as low-volume cheater-
valves, obstruct the air flow. If an air adjusting valve is
desired, use a SHARPE Air Adjusting Valve 24AAV (part
no. 2210), 36AAV-HOV (part no. 3310) or HOV (part no.
U04410).
•Install a shutoff valve (not supplied) downstream of the air
regulator to shut off gun air.
•Install an inline air filter (not supplied) to clean and dry the
air supply to the gun.
1. Turn off air supply.
2. Connect a clean, dry, filtered air supply to gun air inlet (2).
3. If this is first time using the equipment, flush the spray gun.
Operation
Pressure Relief Procedure
1. Turn off gun air supply.
2. Trigger the gun to relieve pressure.
Flushing
Flush before using the equipment, before changing colors, and
when you are done spraying. Use solvent that is compatible with
gun wetted parts and fluid that will be sprayed. Flush at lowest
possible pressure.
1. Follow Pressure Relief Procedure.
2. Dispose of any paint in cup.
3. Fill cup with small amount of solvent.
4. Spray into grounded metal waste container until equipment
is clean.
5. Follow Pressure Relief Procedure.
Spraying
1. Fill cup (101) with material. Do not fill past cup “shoulder”
(A). See FIG. 1.
2. Screw cup (101) onto lid securely.
3. Slowly adjust gun air pressure while fully triggering the gun
until you have the desired atomization.
4. Adjust the pattern size and shape with the spray width
adjustment knob (10). See FIG. 2. Turn knob clockwise to
reduce pattern size and counterclockwise to increase it.
5. Fluid control knob (7) is factory set for maximum needle trig-
ger travel and material flow. To decrease needle/trigger
travel and decrease fluid flow, turn knob clockwise.

WARNING
Read warnings, page 2.
Refer to Compliant Cleaning Methods, page 4, to com-
ply with air quality laws if applicable.
CAUTION
Excessive atomizing air pressure can increase over-spray,
reduce transfer efficiency, result in a poor quality finish
from dry spray.
See Troubleshooting guide if you experience an irregular
pattern.

Cleaning and Maintenance
Volatile Organic Compounds (VOC)
Regulation
In certain states, spraying solvents that release VOC’s into the
atmosphere when cleaning a spray gun is prohibited. To comply
with these air quality laws you must use a cleaning method that
prevents the escape of VOC vapors into the atmosphere. See
Compliant Cleaning Methods below.
Compliant Cleaning Methods
•Place spray gun in a gun washer that completely encloses
the gun and components during cleaning, rinsing, and
draining.
•Spray solvent through the spray gun into a closed gun
cleaning station.
Cleaning Gun and Cup
1. Follow Flushing procedure, page 3.
2. Use a rag moistened in solvent to wipe cup lid (109), fluid
tube (103), inside of cup (101), and outside of gun.
3. Blow dry gun inside and out. Lubricate gun as described in
Spray Gun Maintenance.
Cleaning Nozzle and Air Cap
To clean the air cap and nozzle, remove and soak
them in a compatible cleaning solution. Clean them
and front of gun with a soft-bristle brush dipped
into compatible solvent. Do not use a wire brush or
metal tools. To clean out air cap holes, use a soft
implement, such as a toothpick.
Spray Gun Maintenance
•Frequently lubricate the gun moving parts with a drop of
non-silicone oil (part no. 8255).
•Do not disassemble the spray gun if you are having a spray
pattern problem. Check Troubleshooting, page 5, for infor-
mation on how to correct the problem.
•Check for fluid leakage. Tighten fittings or replace equip-
ment as needed.

WARNING
Follow Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing equipment. Read
warnings, page 2.
CAUTION
•Do not submerge gun in solvent. Solvent dissolves lubri-
cant, dries out packings, and may clog air passages.
•Do not use metal tools to clean air cap holes as this may
scratch them and distort the spray pattern.
•Use a compatible solvent.
•Gun and cup can be cleaned in a gun washer.
Clean air line filters as directed by the manufacturer.
Refer to Compliant Cleaning Methods to comply with air
quality laws if applicable.
CAUTION
•Trigger gun whenever you tighten or remove nozzle to
avoid damaging needle seat and nozzle.
•Do not use metal tools to clean air cap holes as this may
scratch them and distort the spray pattern.

Troubleshooting
WARNING
Follow Pressure Relief Procedure, page 3, before troubleshooting or servicing. Read warnings, page 2.
Problem Cause Solution
Normal pattern No action necessary
Dirty or damaged air cap or fluid nozzle. Rotate air cap 180°.
If pattern follows air cap, problem is in air cap. Clean and
inspect. If pattern is not corrected, replace air cap.
If pattern does not follow the air cap, the problem is with the
fluid nozzle. Clean and inspect the nozzle. If the pattern is
not corrected, replace nozzle.
Pressure too high for viscosity of material
being sprayed.
a. Reduce air pressure.
b. Increase material viscosity
c. Correct pattern by narrowing fan size with spray width
adjustment knob.
Dirty or distorted air horn holes. Rotate air cap 180°.
If pattern follows air cap, problem is in air cap. Clean and
inspect. If pattern is not corrected, replace air cap.
Will not spray. a. Cup is not tight a. Tighten cup lid.
b. Cup empty. b. Fill cup.
c. Air cap not seated. c. Turn spray width adjustment knob fully counterclockwise.
Tighten air cap.
a. Air pressure too low. a. Increase air pressure.
b. Gun held too close to surface. b. Hold gun about 6-8 inches (150-200 mm) from surface.
