Warning
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 the gun at anyone or at any part of the body.
• Do not put your hand or fingers over the gun fluid nozzle.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not “blow back” fluid; this is not an air spray system.
• Follow Pressure Relief Procedure, page 7, when you stop spraying and before cleaning, checking,
or servicing equipment.
• Use lowest possible pressure when flushing, priming, or troubleshooting.
• Never spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. High pres-
sure hose cannot be recoupled; replace the entire hose.
Fire and Explosion Hazard
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 and plastic drop cloths (potential static
arc).
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Keep the work area free of debris, including solvent, rags, and gasoline.
• Ground equipment and conductive objects. See Grounding, page 11.
• Hold gun firmly to side of grounded pail when triggering into pail.
• Use only grounded hoses.
• If there is static sparking or you feel an electric shock, stop operation immediately. Do not use
equipment until you identify and correct the problem.
• If connecting PC for data download, PC must be in non-hazardous location and a safety barrier must
be installed. See Xtreme Mix software documentation.
• Keep a fire extinguisher in the work area.
Electric Shock Hazard
Improper grounding, wiring, or usage of the system can cause electric shock.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and regu-
lations.
• Connect only to grounded power source.
• Turn off and disconnect power at the main switch before disconnecting any cables and before servic-
ing equipment.

Xtreme Mix OEM Models
6309521H
Moving parts hazard
Moving parts can pinch or amputate fingers and other body parts. Pressurized equipment can start acci-
dentally and cause serious injury.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Before checking or servicing equipment, follow Pressure Relief Procedure, page 7. Disconnect
power or air supply.
• Do not move or lift pressurized equipment.
Equipment Misuse Hazard
Misuse can cause serious injury or death.
• For professional use only.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• Read manuals, warnings, tags, and labels before operating equipment. Follow instructions.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment. Use only Graco parts and accessories.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-
ponent. 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.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or overbend hoses or use hoses to pull equipment.
• To lift equipment, follow instruction, page 15.
• Comply with all applicable approval requirements and safety regulations.
Burn Hazard
This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To
avoid severe burns:
• Do not touch hot fluid or equipment.
• Allow equipment to cool completely before touching it.
• Wear gloves if fluid temperature exceeds 110° F (43° C).
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 Material Safety Data Sheet (MSDS) 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 proper 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; and
hearing loss. This equipment includes but is not limited to:
• Protective eyewear
• Gloves, clothing, and respirator as recommended by the fluid and solvent manufacturer
• Hearing protection
Recoil Hazard
The gun can recoil when triggered at a very high pressure. If unprepared, this could force your hand back
or cause you to fall and injure yourself. Be sure you have firm footing and hold the gun securely.

WARNING
Read warnings, page 5, and follow instructions below.
Do not use air supply hose smaller than 3/4” (19
mm) ID. Smaller hose could restrict air flow and
cause alternator, solenoids, or Mac valves to mal-
function. Check air supply gauge at pump
changeover; air pressure should not drop.
36” (914 mm) hoses provided. Installer may pro-
vide different lengths.
The alternator requires 12-15 scfm of air to func-
tion correctly.
• Do not use 3/8” (9.5 mm) ID air supply tubing
longer than 24” (610 mm) from air filter to
control box air inlet.
• Do not restrict control box exhaust air.
Increased back pressure can cause a drop in
alternator power output, resulting in delayed valve
action and processor shutdown and reboot.

Balancing Back Pressure
Flow rates and/or viscosity differences between compo-
nent materials can create different pressure drops from
the proportioner to the manifold, causing unequal back
pressure. This will effect mix ratio accuracy.
To calculate pressure loss:
Pressure Loss = 0.000273 x Q x V L
D4
Q= Flow(GPM)
V = Viscosity in centipoise
L = Length of pipe in feet
D4= Pipe diameter to the 4th power
Example: If you need to pump 1 gpm of high solids paint
(40 seconds in a Zahn #2 cup = 100 cp) 100 ft. in a sys-
tem using 1/4” pipe:
Pressure Loss = 0.000273 x 1 gpm x 100 cp x 100 ft.
(.364 ID) .018 D4factor
Pressure Loss = 152 psi
Reduce pressure loss by using:
• Large diameter pipe or tubing
• Constant tubing or pipe size
• Long runs without bends
• Long radius elbows
You can balance differences in component back pres-
sure by adjusting hose diameter and length.
D4= .018 for 1/4” pipe
.06 for 3/8” pipe
.15 for 1/2” pipe
Using the previous example (.000273 x 1 x 100 x 100 =
2.73):
Pressure drop: 1/4” pipe = 152 psi
3/8” pipe = 46 psi
1/2” pipe = 18 psi
Balance pressure drops in the 2 lines as
instructed below to assure an accurate mix ratio.
This procedure is for the remote fluid manifold
only.

Proper Lifting
309521H 15
Proper Lifting
Either remove the cart handle or secure it to the cart
before lifting the unit. Connect a bridle swing, hooking
an end to each of the Xtreme Mix air motor rings. Hook
the center ring on a hoist. See FIG. 9. Carefully lift the
Xtreme Mix unit; make sure it balances evenly.
Operation and Repair
For operating instructions, including data collection, see
Xtreme Mix Operation manual.
For troubleshooting, alarm information, and repair
instructions, see Xtreme Mix Repair manual.
WARNING
Follow instructions below to avoid dropping or swing-
ing unit or being struck by the cart handle, which can
cause serious injury or damage to equipment.
