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.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or solvent
flowing through the equipment can cause static sparking. 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 sparking).
• Ground all equipment in the work area.
• Never spray or flush solvent at high pressure.
• 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.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they are
anti-static or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment until you
identify and correct the problem.
• Keep a working fire extinguisher in the work area.
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 spray without tip guard installed.
• 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.
• 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 and couplings daily. Replace worn or damaged parts immediately.

Warnings
312879E 3
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 Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Specifications
in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about
your material, request Safety Data Sheets (SDSs) 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.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• 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
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.
• Do not use chlorine bleach.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for
compatibility.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including eye
injury, hearing loss, inhalation of toxic fumes, and burns. Protective 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.

Pressure Relief Procedure
4312879E
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn on/off switch OFF and turn pressure control
knob fully counterclockwise to OFF.
2. Point applicator into hopper. Turn applicator ON.
3. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved:
a. If installed, turn prime valve down to prime
position.
b. VERY SLOWLY loosen the retaining ring (10),
hose end coupling (43), or pressure relief valve
on the sprayer to relieve pressure gradually.
c. Loosen the nut or coupling completely.
d. Clear the obstruction in the hose or tip.
NOTE: If pressure relief valve was used to relieve
pressure, be sure to disassemble and clean thoroughly.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

Flush the Equipment (Solvent-Based Materials)
312879E 5
Flush the Equipment
(Solvent-Based Materials)
• Flush before changing materials, before fluid can
dry or cure in the equipment, at the end of the day,
before storing, and before repairing equipment.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
• Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.
• Do not leave the applicator or any parts in water or
cleaning solvents.
1. Follow Pressure Relief Procedure, page 4.
2. Remove the spray tip and guard by loosening
retaining ring (10).
3. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun until clean solvent
dispenses.
4. Store in a dry location.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.

Setup
6312879E
Setup
Make sure sprayer is turned OFF and unplugged from power
source. Refer to your sprayer instruction manual for priming
and spray instructions.
Airless Spray Setup
Connect Applicator to Sprayer
1. Attach supply hose to sprayer fluid outlet.
2. Attach other end of supply hose to applicator swivel
(17).
3. Refer to sprayer instruction manual for priming
instructions.
Install Applicator Tip and Guard
1. If equipment has recently been operated, perform
Pressure Relief Procedure, page 4.
2. Using a pencil or similar object, insert seal (20) into
back of guard (18).
3. Install guard (18) onto end of applicator (9).
4. Insert tip (19) in guard (18). Tighten retaining nut.
Air Spray Setup
Connect Applicator to Sprayer

Operation
312879E 7
Operation
Airless Spray
1. Be sure the arrow shaped tip (19) faces forward
(spray).
2. Hold applicator perpendicular and approximately
40 in. (1 m) from surface. Move applicator first, then
open applicator to spray a test pattern.
3. Slowly increase pump pressure until coverage is
uniform and even (see sprayer instruction manual
for additional information).
Aligning Spray
1. Perform Pressure Relief Procedure, page 4.
2. Loosen guard retaining nut.
3. Align guard (18) horizontally to spray a horizontal
pattern.
4. Align guard (18) vertically to spray a vertical pattern.
Clear Tip Clog
To avoid tip clogs:
• When the applicator is not in use for extended
periods of time, keep the tip “wet” and perform
Pressure Relief Procedure, page 4.
• Keep tip clean and free of material.
1. Rotate SwitchTip to unclog position. Aim applicator
at floor and turn applicator ON. When clog clears,
turn applicator OFF.
UNCLOG
2. Rotate SwitchTip back to spray position. Turn
applicator ON. Spray test pattern.
SPRAY
Air Spray

additional information).
2. Spray test pattern
3. Turn air knob on and adjust, and/or select another
air nozzle, for desired pattern.
NOTE: Air continues to flow when handle is in off
position to keep material out of air passages.
Cleanup
Flush applicator after each work shift and store in a dry
location. Do not leave the applicator or any parts in
water or cleaning solvents.
