Caution Symbol

CAUTION

This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions.

D Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco

distributor.

D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.

D Check the equipment daily. Repair or replace worn or damaged parts immediately.

D Do not exceed the maximum working pressure of the lowest rated system component. This equip-

ment has a 1000 psi (6.9 MPa, 69 bar) maximum fluid working pressure.

D Route the hoses away from the traffic areas, sharp edges, moving parts, and hot surfaces. Do not

expose Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).

D Do not use the hoses to pull the equipment.

D Use only Graco approved hoses. Do not remove hose spring guards, which help protect the hose

from rupture caused by kinks or bends near the couplings.

D Use fluids or solvents that are compatible with the equipment wetted parts. See the Technical

Data section of all the equipment manuals. Read the fluid and solvent manufacturer’s warnings.

D Comply with all applicable local, state and national fire, electrical and other safety regulations.

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and

state and national guidelines.

solvent manufacturer.

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and result in fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. See Grounding on page 4.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvent or the fluid being

sprayed.

D Extinguish all the open flames or pilot lights in the spray area.

D Electrically disconnect all the equipment in the spray area.

D Keep the spray area free of debris, including solvent, rags, and gasoline.

D Do not turn on or off any light switch in the spray area while operating or if fumes are present.

D Do not smoke in the spray area.

D Do not operate a gasoline engine in the spray area.

D If there is any static sparking while using the equipment, stop spraying immediately. Identify and

correct the problem.

SKIN INJECTION HAZARD

Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause a serious injury.

D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgi-

cal treatment.

D Do not point the spray gun at anyone or at any part of the body.

D Do not put hand or fingers over the spray tip.

D Do not stop or deflect fluid leaks with your hand, body, glove, or rag.

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the spray gun when spraying.

D Be sure the gun trigger safety operates before spraying.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 4 whenever you: are instructed to relieve pres-

sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.

D Tighten all the fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

Setup

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from

starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure, D stop spraying, D check or service any of the system equipment, D or install or clean the spray nozzle.

1. Lock the gun trigger safety.

2. Shut off the power supply to the pump and close any bleed-type master air valves in the air supply.

3. Unlock the gun trigger safety.

4. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun into the pail to relieve pressure.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Proper electrical grounding is essential to reduce the risk of fire or explosion which can result in serious injury and property damage. Also read FIRE OR EXPLOSION HAZARD on page 3.

1. Pump or Sprayer: as instructed in your separate pump or sprayer manual.

2. Air compressor or hydraulic power supply: according to local code.

3. Fluid hoses: use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.

4. Spray gun: obtain grounding through connection to a properly grounded fluid hose and sprayer or pump.

5. Lock the gun trigger safety.

6. Open the pump fluid drain valve (required in the system), having a container ready to catch the drainage.

7. Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the

tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Now clear the tip or hose.

5. Fluid supply container: according to local code.

6. Object being sprayed: according to local code.

7. All solvent pails used when flushing, according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.

8. To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a metal pail, then trigger the gun.

Installation

WARNING

SKIN INJECTION HAZARD

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, follow the Pressure Relief

Procedure on page 4.

NOTE: Numbers and letters in parentheses in the text

correspond to the reference numbers and letters in the text and drawings.

WARNING

SKIN INJECTION HAZARD

Be sure your system has a bleed-type master air valve (pneumatic pumps

only) and a fluid drain valve. These two accessories help reduce the risk of serious injury, including fluid injection, splashing in the eyes, or on the skin, or injury from moving parts, if you are adjusting or repairing the pump or gun.

1. The bleed-type master air valve relieves air

trapped between this valve and the pump after the air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly.

2. The fluid drain valve assists in relieving fluid

pressure in the displacement pump, hose, and gun; triggering the gun to relieve pressure may not be sufficient.

1. Connect a grounded fluid hose to the gun inlet.

2. With no tip installed, start the pump/sprayer. Flush it according to the instructions supplied with it. Prime the system with the fluid you are using.

3. Relieve the pressure.

4. WIth the gun safety latch engaged, unscrew the tip guard (9) and install the tip (A) and gasket (B) in the nut of the tip guard. Screw the assembly firmly onto the gun. TIghten with a wrench. See Fig. 1.

NOTE: Failure to install the tip gasket (B) will result in leaking.

5. Strain the fluid you are spraying if it contains particles which could clog the spray tip.
