Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion 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.
WARNINGWARNINGWARNING
WARNING
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 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.
• Do not spray without tip guard.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
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
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

Warnings
4313294D
WARNINGWARNINGWARNING
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.
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 manu-
facturer’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.
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.

Grounding
Check your local electrical code and proportioner man-
ual 313221 for detailed grounding instructions.
NOTICE
• To prevent cross-contamination of the gun’s wet-
ted parts, do not interchange A component
(white fluid) and B component (red fluid) parts.

Piston Safety Lock (Trigger Lock)
313294D 7
Piston Safety Lock
(Trigger Lock)
Engage piston safety lock whenever you stop spray-
ing, to avoid accidental triggering.
To engage piston safety lock: push knob in and turn
clockwise. If engaged, gun will not actuate.
To disengage piston safety lock: push knob in and
turn counterclockwise until it pops out. There will be a
gap between knob and gun body.
Loss of Air Pressure
In event of loss of air pressure while gun is triggered,
gun will continue to spray. To shut off gun, do one of the
following:
• Push hard or hit end of safety lock, to engage piston
safety lock.
• Close fluid valves A and B.

Pressure Relief Procedure
1. Engage piston safety lock, page 7.
2. Close fluid valves A and B. Leave air valve con-
nected to whip hose open.
3. Disengage piston safety lock, page 7.
4. Ensure RAC tip (65) is in spray position.
5. Trigger gun onto cardboard or into waste container
to relieve pressure.
If you suspect spray tip or hose is clogged or that pres-
sure has not been fully relieved after following the steps
above, VERY SLOWLY loosen tip guard retaining nut or
hose end coupling to relieve pressure gradually, then
loosen completely. Clear hose or tip obstruction.
6. Engage piston safety lock, page 7.
Relieve pressure before cleaning or repairing gun.
NOTICE
Air supply is required for gun actuation. Do not dis-
connect gun air supply until fluid pressure is relieved.

Fluid in the hose and proportioner is still under pres-
sure. Follow the Pressure Relief Procedure in the pro-
portioner manual.
To relieve pressure in the hose after the gun is
removed, place the fluid manifold over containers, fac-
ing away from you. Very carefully open the fluid

If it is necessary to flush the mix module, use following
procedure.
1. Follow Pressure Relief Procedure, page 10.
2. Flush with a compatible solvent.
3. Flush into a grounded metal pail, holding a metal
part of fluid manifold firmly to side of pail. Use the
lowest possible fluid pressure when flushing.
Clean Outside of Gun
Wipe off outside of gun with compatible solvent.
Clean Air Cap
Soak air cap in compatible solvent. If necessary, clean
gently with stiff brush.
Clean Spray Tip
Clean spray tip with a solvent soaked brush. Clean front
of tip frequently to reduce fluid build up. Clean tip and tip
guard at the end of each work day.
Clean Muffler
A partially plugged muffler (51) will slow gun actuation.
Remove and clean muffler with compatible solvent.
Clean Fluid Manifold
Clean fluid manifold sealing faces with compatible sol-
vent and a brush whenever removed from gun. Be sure
to clean the two fluid ports (AB) in the top mating sur-
face. Do not damage the flat sealing surfaces. Cover
with Fusion Lubricant (29) if left exposed, to seal out
moisture.
Clean Mixer
