Warnings
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:
•
•
•
•
Protective eyewear
Clothing and respirator as recommended by the fluid and solvent manufacturer
Gloves
Hearing protection
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
•
•
•
•
•
Turn off and disconnect power cord before servicing equipment.
Use only grounded electrical outlets.
Use only 3-wire extension cords.
Ensure ground prongs are intact on sprayer and extension cords.
Do not expose to rain. Store indoors.
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.
Do not stop or deflect leaks with your hand, body, glove, or rag.

Warnings
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
•
•
Use equipment only in well ventilated area.
Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
•
•

Do not exceed the maximum working pressure or temperature rating of the 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 manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.
Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu-
facturer’s replacement parts only.
•
•
•
•
•
•
Do not alter or modify equipment.
Use equipment only for its intended purpose. Call your distributor for information.

Keep children and animals away from work area.
Comply with all applicable safety regulations.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
•
•

Installation
•
Gun: the gun is grounded by connecting it to the
properly grounded fluid hose and by a ground wire
in the cable. Check ground continuity between the
gun body and the heat control ground lug.
Ground the System
•
•
Fluid supply container: ground according to the
local code.
Flammable liquids in the dispense area: must be
kept in approved, grounded containers. Do not store
more than the quantity needed for one shift.
The following grounding instructions are minimum
requirements for a basic dispensing system. Your sys-
tem 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. Your system must be connected to a true
earth ground.
•
All solvent pails used when flushing: ground
according to local code. Use only metal pails, which
are conductive. Do not place the pail on a non-con-
ductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
•
Fluid hoses: use only grounded fluid hoses with a
maximum of 25 feet (7.5 m) combined hose length
to ensure grounding continuity. Check electrical
resistance of your fluid hoses at least once a week.
If your hose does not have a tag on it that specifies
the maximum electrical resistance, contact the hose
supplier or manufacturer for the maximum resis-
tance limits. If the hose resistance exceeds the rec-
ommended limits, replace it immediately.
To maintain grounding continuity when flushing or reliev-
ing pressure: hold a metal part of the gun firmly to the
side of a grounded metal pail, then trigger the gun. To
reduce the risk of static sparking, ground the pump,
object being dispensed to, and all other spraying/dis-
pensing equipment used or located in the spraying/dis-
pensing area. Check your local electrical code for
detailed grounding instructions for your area and type of
equipment.

Pressure Relief Procedure
Pressure Relief
Procedure
Trigger Lock
Always engage trigger lock when you stop spraying 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. 6.
1. Fully release gun trigger and engage gun trigger
lock. See FIG. 6.
Do not try to force trigger valve open with trigger
lock engaged. This could result in component fail-
ure.
2. Shut off fluid supply pump.
3. Hold a metal part of gun firmly to side of a grounded
metal waste container. Disengage gun trigger lock.
See FIG. 7. Trigger gun to relieve fluid pressure.

Engaged
TI8049
4. Fully release gun trigger and engage gun trigger
lock. See FIG. 6.
FIG. 6: Trigger Lock Engaged
To disengage trigger lock, rotate it upward. See FIG. 7.
5. Open pump drain valve to help relieve fluid pressure
in pump, hose, and gun. Triggering gun to relieve
pressure may not be sufficient. Have a container
ready to catch drainage.
Trigger Lock
Disengaged
6. Leave drain valve open until you are ready to dis-
pense again.
7. If you think the gun nozzle or fluid hose is completely
clogged or that pressure has not been fully relieved
after following the previous steps, very slowly loosen
hose end coupling and relieve pressure gradually,
then loosen coupling completely. Clear nozzle or
hose obstruction

3. Activate heat controls.
Heatup
4. After pump, hose, and gun are up to temperature,
release gun trigger retainer (Z) to close valve.
Engage gun trigger lock to prevent accidental dis-
pense of high pressure heated fluid.
Heated fluid expands, causing a pressure rise in a
closed system.
•
•
Relieve pressure (page 7) before heating up
equipment.
Engage trigger retainer to hold gun open, to pre-
vent excessive pressure buildup.
Z
1. Turn ON electrical controls and main air to unit.
2. Lock dispense valve trigger open by pulling and
securing trigger using trigger retainer (Z).

Operation
Dispensing
Shutdown
1. Start pump. Fluid flow rate is controlled at pump.
Adjust pump pressure to obtain desired flow rate.
Use lowest pressure necessary to dispense fluid.
The pressure adjustment depends on hose length,
fluid viscosity, and nozzle size.
1. Turn off all heat at controller.
2. Shut off fluid supply pump.
3. Trigger gun to relieve pressure while system is still
hot.
2. Disengage gun trigger lock.
4. With gun over a waste container, hold trigger open
by securing with trigger retainer (Z).

Install New Heater Cartridge(s),
RTD Sensor, or Switch
After adjusting or servicing gun, ensure that fluid will
not trigger on when trigger lock is engaged. If fluid
does flow, gun is not assembled correctly or trigger
lock is damaged. Reassemble gun or return it to
your nearest Graco distributor. Do not use gun until
the problem is corrected.

2. Pull terminal block (36) out of handle and discon-
nect lead wires of failed components.
3. Gently slide new heater(s) or sensor into appropri-
ate hole.
1. If fluid continues to flow after trigger is released:
4. Feed new wires through conduit to terminal block
(36) and connect after cutting to length and strip-
ping.

flats of needle to turn needle (4a) clockwise one turn
as viewed from handle end of gun.
Inspection Frequency
Dispense Valve
5. Release trigger; a slight free play of the trigger han-
dle should occur.
Inspect dispense valve at every use for leakage or other
visible damage.
6. Repeat Step 4 until free play occurs.
Heater
7. Tighten hex nut (4g) to lock the adjustment.

TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
