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 and trigger guard installed.
Engage trigger lock when not spraying.
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
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.

WARNING
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 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 ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause a serious chemical reaction and equipment rupture. Failure to follow this warning may 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.
Many other fluids may contain materials that are incompatible with aluminum. Con­tact your material supplier for verification.

WARNING
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.
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.
RECOIL HAZARD
Gun may recoil when triggered. If you are not standing securely, you could fall and be seriously injured.
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

Pressure Relief Procedure
Pressure Relief Procedure
Follow this Pressure Relief Procedure whenever you are instructed to relieve pressure, stop spraying, check or service equipment, or install or clean spray tip.
1. Engage trigger lock.
2. Shut off pump.
3. Disengage trigger lock.
4. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.
5. Engage trigger lock.
6. Open fluid drain valve (see System Requirements). Leave drain valve open.
If pressure is not fully relieved:
Spray tip is clogged. For RAC tip, see Cleaning Tips/Clearing Clogs, page 6. For flat tip, slowly loosen tip guard retaining nut to relieve pressure. Remove and clear tip.
Hose is clogged. Slowly loosen hose end coupling to relieve pressure. Clean hose obstruction.
Grounding
Check your local electrical code and pump/sprayer manual for detailed grounding instructions.
Spray gun: ground through connection to a grounded fluid hose and pump/sprayer.
Fluid hose: use only grounded hoses.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent flushing pails: follow local code. Use only conductive metal pails placed on a grounded surface. Do not place pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.
To maintain grounding continuity when flushing or relieving pressure: hold metal part of gun firmly to side of a grounded metal pail, then trigger gun.
Gun Trigger Lock
System Requirements
Install a bleed-type master air valve on a pneumatic pump air supply line to relieve air trapped between this valve and pump after air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly.
Install a fluid drain valve between the pump and gun to relieve pressure in displace­ment pump, hose, and gun. Triggering to relieve pressure may not be sufficient. See
Pressure Relief Procedure.
To prevent injury when the gun is not in use, always engage the gun’s trigger lock if unit is being shut down or left unattended. A wallet-sized warning card with important injection treatment information is included with the gun. Additional cards are available at no charge. Provide a card to all operators.
The trigger lock must move freely, and easily snap into a locked position. If the trigger lock is damaged or movement is restricted, replace with new trigger kit (16) immediately.

Tip Installation
Tip Installation
RAC Tip
1. Follow Pressure Relief Procedure. Engage trigger lock.
2. Snap gasket (20b) on fluid seal (20a). Use tool (A) to insert gasket and seal into housing, seal first. Tip the tool to remove it when seal is in place.
3. Install tip cylinder (20c) as shown. Turn 90 ° counterclockwise to spray position, so the arrow faces forward. Install assembled RAC onto spray gun.
Flat Tip
1. Follow Pressure Relief Procedure. Engage trigger lock.
2. Insert tip (32) and gasket (30) into back of guard (31).
3. Install guard over end of gun.

7. Hold gun perpendicular and approximately 12 inches (304 mm) from surface. Wear gloves if fluid temperature exceeds 110°F (43°C).
8. Move gun first, then pull gun trigger to spray onto test paper.
a. Adjust fluid pressure until spray is com-
pletely atomized.
b. If adjusting pressure does not give a
good spray pattern, follow Pressure Relief Procedure, then try another tip size.
9. Trigger gun full-open or full-close.
Adjusting Spray Pattern
