Warnings
The following warnings are for the setup, use, maintenance, and repair of this equipment. The exclamation 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-specific
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.
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.

Warnings
3A6714B 5
PRESSURIZED EQUIPMENT HAZARD
Over-pressurization can result in equipment rupture and serious injury.
• A pressure relief valve is required at each pump outlet.
• Follow the Pressure Relief Procedure in this manual when servicing equipment.
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.

Choose an Installation Location
• Select a location that will support the weight of the
pump and lubricant, as well as all plumbing and
electrical connections.
• Refer to the two mounting hole layouts provided in
the Mounting Pattern section of this manual, page
31.
• Use designated mounting holes and provided con-
figurations only.
• Use the two fasteners (included) to secure the pump
to the mounting surface.
Some installations may require an additional pump
bracket.

Fuses
Fuse kits are available from Graco. The following table
identifies the correct fuse to use for the input voltage
and the corresponding Graco Kit number.
Recommendations for Pump Usage in
Harsh Environments
• Use pump with CPC style power cable.
• Use a corrosion preventative electrical grease on all
contacts.
AUTOMATIC SYSTEM ACTIVATION HAZARD
Unexpected activation of the system could result in
serious injury, including skin injection and amputa-
tion.
This device has an automatic timer that activates the
pump lubrication system when power is connected or
when exiting the programming function. Before you
install the lubrication pump or remove it from the sys-
tem, disconnect and isolate all power supplies and
relieve all pressure.

NOTICE
The stirring paddle should rotate clockwise (as viewed
from the top) (FIG. 4) when power is applied. Allowing
the stirring paddle to rotate counterclockwise dam-
ages the pump’s internal components.
If the stirring paddle is rotating counterclockwise, stop
the pump immediately. Check that the wiring is correct
and make any necessary changes.
If the motor does not run after power is supplied,
check the pump wiring.
