Installation/Operation

System Requirements

WARNING

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.

1. The pressure drain valve assists in relieving fluid

pressure in the displacement pump, hose and gun;

triggering the gun to relieve pressure may not be

sufficient.

2. Strain the fluid you are spraying if it contains

particles which could clog the spray tip.

Ground the System

WARNING

To reduce the risk of static sparking, ground the

pump and all other equipment used or located in

the spray area. 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 con-

nection to a properly grounded fluid hose and pump

or sprayer. Also read FIRE OR EXPLOSION HAZ-

ARD on page 3.

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

To reduce the risk of serious injury, including fluid

injection, splashing fluid or solvent in the eyes or

on the skin, follow this procedure when you are

instructed to relieve pressure, when you stop

spraying, shut off the pump, check or service any

system equipment, or install, clean or change spray

tips.

WARNING

1. Lock the gun trigger safety.

2. Shut off the power to the pump.

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 drain valve, having a container ready to

catch the drainage. Observe the pressure gauge.

The gauge reads 0 psi/bar when fully drained.

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,

very slowly loosen the tip guard retaining nut or hose

end coupling and relieve pressure gradually. Clean the

tip or hose obstruction.
