WARNINGS

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.

• When flammable liquid is sprayed or used for flushing or cleaning, keep sprayer at least 20 feet (6 m)
away from explosive vapors.

• 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 work area. See Grounding instructions.

• 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 fire extinguisher in the work area.

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 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.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• For professional use only.

• 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 kink or over bend hoses or use hoses to pull equipment.

• 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.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

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 when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

Fluid Flow

1 To obtain maximum fluid flow, turn fluid adjustment

knob (21) counterclockwise until trigger (10) moves
freely. Fig. 2.

2 For remote pressure pot, hold gun parallel to floor

and adjust fluid pressure at 8-10 inch (203 to 254
mm) fluid stream. Fig. 3.

For 2-quart remote pressure pot: Set at 4 to 6 psi
(0.28 to 0.42 bar).

3 If further gun fluid adjustment is needed, turn fluid

adjustment knob (21) clockwise to reduce volume of
fluid output. Fig. 4.

CAUTION

Restricting the trigger and fluid needle travel by con­tinuously spraying with fluid adjustment knob closed
(turned clockwise), will cause accelerated abrasive
wear on fluid needle and wear on trigger.

For 2-1/2 gallon remote pressure pot: Set at 8 to 10
psi (0.56 to 0.70 bar).

Note: Heavier fluids or longer fluid hoses require
greater pressures.

WAR NING

Over-pressurizing the accessory remote pres­sure pot can cause serious injury. To reduce the
risk, never exceed 50 psi (0.35 MPa, 3.5 bar)
Maximum Inlet Fluid Pressure.

gun about 6 to 8 inches (150 to 200 mm) from test
piece.

5 Air Control Valve (B) on end of gun, controls both

atomizing air and pressure in spray gun cup. Adjust
air control valve as needed. Fig. 5.

NOTES:

• Control over-spray mist by using only as much air as
necessary to spray fluid. Lighter fluids require less
air.

• If atomization is still unacceptable, fluids may be
thinned further or a different fluid set may be
required. Refer to page 8 to determine fluid set or
page 9 to prepare fluid.

Selecting the Pattern Shape

The Pattern Selection Knob (A) determines the shape of
the spray pattern. To create a round spray pattern set
the pattern selection knob (A) to RND. To create a fan
pattern, set the pattern selection knob (A) to FAN. Fig. 7.

Adjusting the Pattern

Change the pattern by adjusting the fluid knob (21) and
pattern selection knob (A).

Note: Reducing fluid flow rate or turning air knob to
RND will reduce pattern width. Using air cap 244227
will create a highly productive, wider pattern. Fig. 8.

The air control (B) controls the TOTAL air to the pattern
and gun. Fig. 6.

As the fluid flow rate is reduced, the pattern becomes
smaller.

Using too much air will cause overspray.

Selecting Fluid Sets

The Turbine Spray Gun includes a #3 fluid set, Part No.

244124. Grooves at the end of fluid needle indicate the
size of fluid set.

Fluid sets include a nozzle (14a) o-ring (4) and needle
assembly (14b). Fig 9.

Note: To order other replacement parts for gun, see
parts drawing and list for gun model on page 22.

WAR NING

Do not exceed gun’s 50 psi (0.35 MPa, 3.5 bar)
Maximum Fluid Inlet Fluid Pressure and 10 psi
(0.07 MPa, 0.7 bar) Maximum Inlet Air Pressure.
Higher pressures can cause parts to rupture and
result in serious injury or property damage.

Turbine spray gun fluid sets range in size to provide dif­ferent fluid flow rates. Selection charts on page 8 show
recommended combinations based on fluid viscosities,
flow rates, and usage.

As a general guideline, use fluid nozzle that will give
required flow with needle fully triggered at lowest fluid
pressure.

For low flow rates or light viscosity fluid, select smaller
nozzle sizes.

For high flow rates or high viscosity fluid, select larger
nozzle sizes.

Graco offers six different fluid sets:

Installing Fluid Set

CAUTION

Trigger gun whenever you tighten or remove nozzle.
This keeps needle seat away from nozzle seating sur­face and prevents the seat from being scratched.

Complete spray guns are available with a #3 fluid set. To
install other fluid sets, perform the following steps. Fig.

11.

1 Use your hand to loosen and remove the air cap

retaining ring (13) and air cap housing (15).

2 While triggering gun, use your hand to loosen and

remove nozzle (14a) from gun.

3 Use your hand to loosen and remove fluid knob

assembly (21) and compression spring (23) from
back of gun and remove old needle.

4 Insert needle assembly (14b) into the back of gun.

Replace nozzle (14a) air cap housing (15) and air
cap retaining ring and tighten by hand.

Note: O-ring (4) should always be on the nozzle.
