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).
• Keep work area free of debris, including solvent, rags, and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground equipment and conductive objectives. See Grounding in your sprayer manual.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not exceed maximum working pressure or temperature rating of the lowest rated system compo-
nent. 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.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• For professional use only.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• 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 swal-
lowed.
• 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.
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:

Set-Up
4 309926C
Set-Up
Pressure Relief Procedure
1. Shut off air supply to the tank by closing air valve.
2. Pull ring on safety valve until pressure bleeds down.
Material Preparation
Follow manufacturer’s directions for mixing and
preparing material.
Strain material using a fine mesh screen to prevent
foreign matter from entering and clogging passageways.
Tank Assembly
1. Install tank handle and lock nut by turning handle
clockwise 4-5 turns. Position handle so it is parallel
to safety valve branch tee.
2. Secure in place by tightening lock nut using a 9/16”
open end wrench.
3. Install regulator U10004 by tightening swivel
adapter nut U23040 onto nipple U09993. Position
unit so gauge is facing the same direction as safety
valve ring. Use 11/16” open end wrench to tighten
swivel adapter nut.
WARNING
Pressure tanks remain pressurized until pressure is
manually relieved. To reduce the risk of serious injury
from pressurized fluid or accidental spray from gun,
always follow this procedure to relieve pressure in the
tank:
• Before you check or service any part of the spray
system.
• Before you loosen or remove the pressure tank
cover or fill port.
• Whenever you stop spraying.
Tank handle must be attached before installing
regulator.

Installation
309926C 5
Installation
1. Follow Pressure Relief Procedure, page 4.
2. Slowly loosen thumb screws, tip lid clamps back and
remove lid assembly.
3. Pour material into tank. Use part no. U07050
Disposable Tank Liners for easy clean-up.
4. Replace lid assembly and tighten clamps and thumb
screws securely.
5. Pass air supply line through Air Control Unit to filter
dirt from air and extract water and oil. Connect air
supply hose to air inlet fitting on tank regulator.
6. Attach atomization air hose to the air outlet fitting
which is directly opposite air inlet fitting on tank
pressure regulator.
7. Connect material hose to fluid outlet fitting on top of
tank lid.
WARNING
• A safety valve protects tank from over pressuriza-
tion. During each use, pull ring on safety valve to
check if it operates freely and relieves air pressure.
If the valve is stuck, does not operate freely, or does
not relieve air pressure, it must be replaced.
• Do not discard or make any alterations or substitu-
tions to safety valve.
• Do not make any changes to the pressure tank.
Tampering in the form of drilling, welding, etc., will
weaken the tank.
The following information is for a typical
installation.

Operation
6 309926C
Operation
1. Turn on air supply.
2. Turn T-handle adjusting screw clockwise on the tank
pressure regulator, while pulling the gun trigger fully
back to start material flow.
3. Continue turning T-handle clockwise until desired
material flow is achieved. To decrease pressure turn
T-handle counter-clockwise to a lower setting. Then
relieve pressure in tank by pulling the ring on the
safety valve.
4. Atomization air for the spray gun can be adjusted
using the air adjusting valve on the spray gun or at
the air regulator assembly (Model 234415 only) on
the pressure tank.
5. Operate spray gun according to instructions
accompanying gun.
Maintenance
Cleaning the Tank
1. Turn off main air supply to tank.
2. Follow Pressure Relief Procedure, page 4.
3. Turn T-handle adjusting screw on regulator,
counter-clockwise until no spring tension is felt.
4. Slowly loosen thumb screws, tip clamps back and
tip tank lid to one side.
5. Loosen spray gun air cap ring about three turns.
6. Turn on air supply.
7. Hold a cloth over air cap on gun and pull trigger.
This forces material back through the hose, into the
tank.
8. Empty and clean tank and parts using a suitable
solvent.
9. Pour solvent into tank.
10. Replace lid and tighten thumb screws and clamps.
11. Turn T-handle on tank regulator clockwise while
pulling gun trigger fully back and spray until clean
solvent appears.
12. Repeat steps 1-3.
Decorative powder coating may be affected by
solvent contact. Avoid prolonged exposure of
solvents to powder coated areas. Tank has been
zinc plated underneath the decorative coating for
rust protection.
