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 symbol refers
to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings
may be found 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 lights on or off when flammable fumes are
present.

• Ground all equipment in the 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 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 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 Pressure Relief Procedure in this manual, 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.

Setup

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 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.

• Always wear impervious gloves when spraying or cleaning equipment.

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

Setup

Reference numbers and letters in paren­theses in the text refer to numbers and
letters in the illustrations.

1. Install an air pressure regulator on gun air
supply line to control air pressure.

2. Install a shutoff valve downstream of the air
regulator to shut off gun air.

3. Connect a clean, dry, filtered air supply to
air inlet fitting (13). Connect other end to
shutoff valve.

4. Install fluid filter into fluid inlet.

5. Screw on gravity cup.

6. Remove gravity cup cover and fill cup with
solvent to flush if this is first time using
equipment. (See Flushing, page 5.)

7. After flushing, fill cup with fluid and attach
cover.

Operation

Operation

Pressure Relief Procedure

1. Turn off gun air supply.

2. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger gun to relieve
pressure.

Adjust Spray Pattern

Do not exceed maximum working air pressure
shown on front cover. Read warnings.

1. Rotate air cap (1) to change spray pattern
direction.

2. For maximum fluid flow and to prevent
premature fluid nozzle wear, turn fluid
adjustment knob (8-2) counterclockwise
until no trigger restriction is felt. Then turn
knob out 1/2 turn more.

3. If further fluid flow restriction is needed,
use different size needle/nozzle/air cap
combination.

a. If pattern is too wide, turn pattern

adjustment knob (5) clockwise to
narrow pattern.

b. To create a round pattern, turn pattern

adjustment knob (5) fully clockwise.

c. If pattern is too narrow, turn knob (5)

counterclockwise.

d. Check atomization. Increase gun air

supply pressure in 5 psi (34 kPa,

0.3 bar) increments until you have
the desired atomization.

Applying Paint

For the best results:

• Keep gun perpendicular to surface and
consistent distance of about 6-8 inches
(150-200 mm). Do not angle the gun as you
spray.

• Use smooth, even strokes, with about 50%
overlap.

• Mini-HVLP and HVLP Guns: Use a slightly
slower hand movement and make fewer
passes than you would with a conventional
air spray gun. Take care to avoid runs or
sags.

If necessary, fluid adjustment knob (8-2)
can be turned clockwise to reduce volume
of fluid output. However, continuously
spraying with fluid adjustment knob closed
causes accelerated abrasive wear on fluid
needle and trigger/air valve shaft interface.

If fluid adjustment knob (8-2) is turned in
all the way, the gun emits only air.

4. Test spray pattern and atomization
while holding gun about 6 to 8 inches
(150 to 200 mm) from test piece.

Maintenance

Maintenance

Flushing

Flush before changing colors, before fluid can
dry in the equipment, at the end of the day,
before storing, and before repairing equip­ment. Use solvent that is compatible with gun
wetted parts and fluid that will be sprayed.

1. Follow Pressure Relief Procedure,

page 4.

2. Dispose of any paint in the cup.

3. Fill the cup with a small amount of solvent.

4. Spray into a grounded metal waste con­tainer until clean solvent dispenses.

4. Flush gun before changing colors and
when you are done spraying.

5. Remove cup and filter and clean them.

6. Remove air cap (1) and nozzle (2) as
instructed on page 7 and soak them in
compatible solvent.

CAUTION

Trigger gun and use gun tool (27) whenever
you tighten or remove nozzle (2) to avoid
damaging needle seat and nozzle.

7. Use a rag moistened in solvent to wipe
down outside of gun.

8. Before reinstalling air cap and nozzle, 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.

5. Follow Pressure Relief Procedure,

page 4.

Daily Cleaning

CAUTION

• Do not submerge gun in solvent. Solvent
dissolves lubricant, dries out packings, and
may clog air passages. You can immerse
front end of gun in solvent just until cup
connection is covered.

• Do not use metal tools to clean air cap
holes as this may scratch them and distort
the spray pattern.

• Use a compatible solvent.

1. Follow Pressure Relief Procedure,

page 4.

2. Clean fluid and air line filters.

9. Lubricate gun.

3. Check for fluid leakage from gun and fluid
hoses. Tighten fittings or replace equip­ment as needed.
