Warnings
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
equipment.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.
• Connect only to grounded power source.
SKIN 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 surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or
swallowed.
• Read MSDS’s 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.
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause death or serious injury.
• Do not exceed maximum working pressure or temperature rating of lowest rated system component.
See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturers warnings.

Grounding and Electrical Requirements
Grounding and Electrical Requirements
1. Pump: connect a ground wire and clamp to a true
earth ground as shown in pump manual.
2. Applicator: ground through motor cable assembly.
The following are minimum requirements for a basic dispensing system. Your system may include other equipment or objects that must be grounded. Check your local
electrical code for detailed grounding instructions for
your area and type of equipment.
To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of spray gun
firmly to side of a grounded metal pail. Then trigger
spray gun.

3. Fluid and air hoses: only use electrically conduc-
tive material and air hoses.
4. Dispense gun: ground through connection of hose
or cable.
5. Air compressor: follow manufacturer’s recommen-
dations.
6. Object being sprayed: refer to local code.
7. Fluid supply container: refer to local code.

Installation
Installation
Inspect flow gun for shipping damage. If damage is
found notify the carrier immediately.
If material hose will be suspended by a hanger or
tool balancer, route hose through the suspension
device before
1. Connect flow gun to any standard Graco hose
assembly.
2. Connect the opposite end of the heated hose
assembly to any fluid supply system. See Model
table, page 2 for maximum fluid working pressure
for your gun model.
3. Tighten fluid connections.
4. Before operating gun, squeeze and release trigger a
few cycles. Observe action of cartridge assembly.
securing each end of material hose.
Pressure Relief Procedure
To help prevent injuries, follow this procedure
when you shut off the flow gun and before checking or adjusting any part of gun.
If you suspect the tip/nozzle or hose is completely
clogged or that pressure has not been fully relieved after
following the above steps, VERY SLOWLY loosen the
retaining nut or hose end coupling to relieve pressure
gradually. Then loosen it completely. Clear tip/nozzle or
hose.
Trigger Lock
Always engage trigger lock when you stop dispensing to
prevent gun from being triggered accidentally by hand or
if dropped or bumped.
To engage trigger lock, release trigger and rotate lock
downward. See Fig. 1.
Do not try to force trigger valve open with trigger
lock engaged. This could result in component failure.
