Warning
WARNING
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 medical attention.
• Do not point the gun at anyone or at any part of the body.
• Do not put your hand or fingers over the gun fluid nozzle.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not “blow back” fluid; this is not an air spray system.
• Follow
Pressure Relief Procedure , page 6, when you stop spraying and before cleaning, checking,
or servicing equipment.
• Use lowest possible pressure when flushing, priming, or troubleshooting.
• Never spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. High pressure hose cannot be recoupled; replace the entire hose.
FIRE AND EXPLOSION HAZARD
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 and plastic drop cloths (potential static arc).
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Keep the work area free of debris, including solvent, rags, and gasoline.
• Ground equipment and conductive objects. See Grounding
• Hold gun firmly to side of grounded pail when triggering into pail.
• Use only grounded hoses.
• If there is static sparking or you feel a shock, stop operation immediately.
Do not use equipment until you identify and correct the problem.
EQUIPMENT MISUSE HAZARD
Misuse can cause serious injury or death.
• For professional use only.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• Read manuals, warnings, tags, and labels before operating equipment. Follow instructions.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment. Use only Graco parts and accessories.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See
in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See
in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not use hoses to pull equipment.
• Comply with all applicable safety regulations.

System Requirements
WARNING
BURN HAZARD
This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To avoid severe burns:
• Do not touch hot fluid or equipment.
• Allow equipment to cool completely before touching it.
• Wear gloves if fluid temperature exceeds 110° F (43° C).
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 Material Safety Data Sheet (MSDS) 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.
PERSONAL PROTECTIVE EQUIPMENT
You must wear proper 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, and hearing loss. This equipment includes but is not limited to:
• Protective eyewear
• Gloves, clothing, and respirator as recommended by the fluid and solvent manufacturer
• Hearing protection
RECOIL HAZARD
The gun can recoil when triggered at very high pressure. If unprepared, this could force your hand back or cause you to fall and injure yourself. Be sure you have firm footing and hold the gun securely.
System Requirements
• Install a bleed-type master air valve on a pneumatic pump air supply line to relieve air trapped between this valve and the 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 gun to relieve pressure may not be sufficient. See
Pressure Relief Procedure , page 6.

Grounding
Grounding
WARNING
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.
Ti1102 1
• To maintain grounding continuity when flushing or relieving pressure: hold metal part of gun firmly to side of grounded metal pail, then trigger gun.
Gun Trigger Safety
WARNING
To engage trigger lock: turn it to position A. If engaged, gun will not trigger. Engage trigger lock whenever you stop spraying to avoid accidental triggering.
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.

To disengage trigger lock: turn it to position B.

5.
Engage trigger lock.
WARNING
1.
Engage trigger lock.
6.
Open fluid drain valve; have a container ready to catch drainage. Leave drain valve open until you start spraying again.
2.
Shut off pump. Close bleed-type master air valve
(pneumatic pumps only).

3.
Disengage trigger lock.
4.
Hold a metal part of the gun firmly to a grounded metal pail. Trigger gun to relieve pressure.
7.
If you suspect that pressure is not fully relieved because:
• Spray tip is clogged
SwitchTip:
Flat Tip: Very slowly loosen tip guard retaining nut and relieve pressure gradually then loosen completely. Clear tip.
• Hose is clogged
Slowly loosen hose end coupling and relieve pressure gradually. Clean hose obstruction.

Operating Gun
Operating Gun
Strain the fluid if it contains particles that could clog fluid tip.
1.
Connect a grounded fluid hose to the gun.
5.
Install GHD RAC spray tip and tip guard as instructed in the enclosed GHD RAC tip instructions. See
Adjusting Spray Pattern , page 8, for
information on positioning for a vertical or horizontal pattern.
2.
Without spray tip installed, flush pump as instructed in pump manual. Use lowest pressure possible. Be sure you have a firm footing and hold gun securely.
6.
Start pump and spray onto test paper.
a.
Adjust fluid pressure until spray is completely atomized. Use lowest pressure possible; higher pressure may not improve spray pattern and causes premature tip and pump wear.
b.
If adjusting pressure does not give a good
spray pattern, follow Pressure Relief Procedure , page 6, then try another tip size.

Adjusting Spray Pattern
Spray Pattern Size
The spray tip orifice and spray angle determine pattern coverage and size. When you need more coverage, use a larger spray tip rather than increasing fluid pressure.

For a vertical pattern, turn tip guard to position E.
For a horizontal pattern turn to position D.
