WARNING

INJECTION HAZARD

Keep the wallet-sized warning card,

provided with this gun, with the operator

at all times. The card contains important

treatment information should an injection injury

occur. Additional cards are available at no charge

from Graco Inc.

WARNING

The equipment must have a bleed-type master air

valve (pneumatic pumps only) and a fluid drain

valve. These accessories help reduce the risk of

serious injury from injection, splashing in the eyes

or on the skin, or moving parts, when adjusting or

repairing the pump or gun.

1. The bleed-type master air valve relieves air

trapped between this valve and the pneumatic

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 pres-

sure in the displacement pump, hose and gun;

triggering the gun to relieve pressure may not be

sufficient.

Ground the System

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding could cause static

sparking, which could cause a fire or

explosion. To reduce the risk of property

damage or serious injury, ground the

pump and all other equipment used or

located in the spray area. Also read FIRE OR

EXPLOSION HAZARD on page 4.

Check your local electrical code for detailed grounding

instructions for your area and type of equipment. Also

follow the grounding instructions provided in your

pump or sprayer manual. The gun obtains grounding

through connection to a properly grounded fluid hose

and pump or sprayer.

How to Use the Gun Trigger Safety

1. To lock the gun trigger safety, turn the safety to a

right angle with the gun body. See Fig. 1.

2. To unlock the gun trigger safety, push the safety

out and turn it parallel with the gun body. See

Fig. 1.

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually

relieved to prevent the system from

starting or spraying accidentally. Fluid

under high pressure can be injected through the

skin and cause serious injury. To reduce the risk of

an injury from injection, splashing fluid, or moving

parts, follow the Pressure Relief Procedure

whenever you:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray tip.

1. Lock the gun trigger safety.

2. Shut off the power to the pump. Open the bleed-

type master air valve (pneumatic pumps only).

3. Unlock the gun trigger safety.

4. Hold a metal part of the gun firmly to a grounded

metal pail. Trigger the gun to relieve pressure.

5. Lock the gun trigger safety.

6. Open the fluid drain valve, having a container

ready to catch the drainage. Leave the drain valve

open until you are ready to spray again.

7. If you suspect that the spray tip or hose is com-

pletely clogged or that pressure has not been fully

relieved, very slowly loosen the tip guard retaining

nut or hose end coupling and relieve pressure

gradually. Clean the tip or hose obstruction.

How to Operate the Gun

WARNING

RECOIL HAZARD

Due to the very high pressure, a strong

recoil action will occur when you trigger

the gun. If you are unprepared, your

hand could be forced back toward your body or you

could lose your balance and fall, resulting in seri-

ous injury.

WARNING

INJECTION HAZARD

To reduce the risk of serious injury,

including injection:

DDo not exceed the maximum working pressure

of the gun or the lowest rated component in the

system.

DFollow the Pressure Relief Procedure on page

7 whenever you are instructed to relieve the

pressure.

Fig. 2

03967

NOTE: Strain the fluid you are spraying if it contains

particles which could clog the spray tip.

1. Connect a grounded fluid hose (A) to the gun inlet.

See Fig. 2.

2. With no tip installed, start the pump. Flush the

pump according to the instructions supplied with it.

Use the lowest pressure possible. Be sure you

have a firm footing and hold the gun securely.

Prime the system with the material.

3. Relieve the pressure.

4. Install the SwitchTip (8) and tip guard (30). Follow

the instructions in the manual, supplied. See

Fig. 2.

5. Start the pump. Trigger the gun onto test paper.

Adjust the fluid pressure until the spray is

completely atomized. Use the lowest pressure

necessary to get the desired results. Higher pres-

sure may not improve the spray pattern and will

cause premature tip and pump wear.

6. If adjusting the pressure does not give a good

spray pattern, relieve pressure and then try

another tip size.

7. Use a full-open, full-close trigger action. Hold the

gun about 14 in. (350 mm) from and at right angles

to the work surface. Don’t swing the gun in an arc.

Practice to find the best length and speed of

stroke.

How to Adjust the Spray Pattern

1. To adjust the spray pattern direction, relieve pres-

sure. Loosen the tip guard retaining nut (B). Turn

the tip guard/tip groove horizontally (C) for a

horizontal pattern and vertically (A) for a vertical

pattern. Tighten the nut. See Fig. 3.

2. The spray tip orifice and spray angle determines

the coverage and size of pattern. When more

coverage is needed, use a larger spray tip rather

than increasing fluid pressure.

CAUTION

Openings in the tip guard reduce paint buildup on the

guard while spraying. Damage to the sharp edges of

the openings causes paint to collect at that area.

Never hang the gun by the tip guard.

splashing in the eyes or on the skin:

DDo not place a hand, body or rag in front of the

spray tip when cleaning or checking a clogged

tip. Point the gun toward the ground or into a

waste container when checking to see if the

spray tip is cleared.

DDo not try to “blow back” paint; this is not an air

spray gun.

DDo not wipe fluid buildup off the gun or spray tip

until pressure is relieved. Follow the Pressure

Relief Procedure on page 7 whenever you

are instructed to relieve the pressure.

Cleaning during the day

1. Relieve the pressure.

2. Clean the front of the tip frequently during the day

to help reduce fluid buildup. Also clean the tip and

tip guard at the end of each work day. Use a

solvent-soaked brush to clean the spray tip.

If the spray tip clogs while spraying

1. Stop spraying immediately.

2. Lock the gun trigger safety. Rotate the RAC IV tip

handle back 180_. See Fig. 4.

3. Unlock the gun trigger safety. Trigger the gun into

a pail or onto the ground to remove the clog.

4. Lock the gun trigger safety. Rotate the tip handle

to the spraying position. See Fig. 4.

5. If the tip is still clogged, engage the gun trigger

safety, shut off the sprayer and disconnect the

power source, and open the fluid drain valve to

relieve pressure. Clean the spray tip as shown in

manual 307991, supplied with the RAC IV.

CAUTION

Do not soak the entire gun in solvent. Prolonged
