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.

Installation/Operation

Pressure Relief Procedure

WARNING
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.
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.
