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 symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-spe-
cific hazard symbols and warnings not covered in this section may appear throughout the body of this manual
where applicable.
WARNING
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, 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 dispensing device at anyone or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking,
or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.
PRESSURIZED EQUIPMENT HAZARD
Over-pressurization can result in equipment rupture.
• A pressure relief valve is required at each pump outlet.
• Follow the Pressure Relief Procedure in this manual before servicing.

Warnings
6 3A6319E
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) from distributor or
retailer.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and
create safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PLASTIC PARTS CLEANING SOLVENT HAZARD
Many cleaning solvents can degrade plastic parts and cause them to fail, which could cause serious
injury or property damage.
• Use only compatible solvents to clean plastic structural or pressure-containing parts.
• See Technical Specifications in all equipment manuals for materials of construction. Consult the
solvent manufacturer for information and recommendations about compatibility.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.

Installation
Unpack
The pump module was carefully packaged for shipment
by Graco. When the package arrives, perform the fol-
lowing procedure to unpack the units:
1. Inspect the shipping box carefully for shipping
damage. Contact the carrier promptly if damage is
discovered.
2. Unseal the box and inspect the contents carefully.
There should not be any damaged parts.
3. Compare the packing slip against all items included
in the box. Any shortages or other inspection
problems should be reported immediately.
Choose an Installation Location
• Select a location that adequately supports the
weight of the G3 pump and lubricant, as well as all
plumbing and electrical connections.
• Refer to the mounting hole layouts provided in
Mounting Bracket Dimensions, page 21. No other
installation configuration should be used.
• Use designated mounting holes and provided con-
figurations only.
• Use the five (5) fasteners (included) to secure the
G3 pump to the mounting surface. Three (3) fasten-
ers are used for the bottom bracket and two (2) fas-
teners are used for the top bracket.
• Adjust top mounting bracket, if necessary, to align
the bracket with the mounting surface (FIG. 5).
• Insert (user supplied) spacers if there is still a gap
after adjusting the bracket.
System Wiring
Fuses
Fuse Kits are available from Graco. The table identifies
the correct fuse to use for the input voltage and the cor-
responding Graco Kit number.
Recommendations for Pump Usage in
Harsh Environments
• If using a DIN style power or alarm harness with a
right angle mating connector, make sure the con-
nector does not exit the unit in the UP direction.
• Use a corrosion preventative electrical grease on all
contacts.
NOTICE
To prevent equipment damage, observe precautions
for handling electrostatic sensitive devices. Touch
ground before handling pump.
AUTOMATIC SYSTEM ACTIVATION HAZARD
If the system is equipped with an automatic timer
(user supplied) that activates the pump lubrication
system when power is connected, or when exiting
the programming function, unexpected activation of
the system could result in serious injury, including
skin injection and amputation.
Before installation or removal of the lubrication pump
from the system, disconnect and isolate all power
supplies and relieve all pressure.
FIG. 5
NOTICE
Fuses (user supplied) are required on all DC mod-
els. To avoid equipment damage:
• Never operate G3 pump DC models without a
fuse installed.
• A fuse of the correct current rating must be
installed in line with the power entry to the
equipment.
Input Voltage Fuse Value Graco Kit No.
