Warnings

The following warnings are for the setup, use, grounding, 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

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 power or light switches on or off when flammable fumes are present.

• Ground all equipment in the work area. See Grounding instructions.

•Use only grounded hoses.

•Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they are antistatic or conductive.

•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until you identify and correct the problem.

•Keep a working fire extinguisher in the work area.

SKIN INJECTION HAZARD

High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that injection occurs, get immediate surgical treatment.

• Do not aim the gun at, or spray any person or animal.

• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with any part of the body.

•Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.

•Use Graco nozzle tips.

•Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while spraying, follow the Pressure Relief Procedure for turning off the unit and relieving the pressure before removing the nozzle tip to clean.

•Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn off the unit and follow the Pressure Relief Procedure for turning off the unit.

•Check hoses and parts for signs of damage. Replace any damaged hoses or parts.

•This system is capable of producing 7250 psi (50.0 MPa, 500 bar). Use Graco replacement parts or accessories that are rated a minimum of 7250 psi (50.0 MPa, 500 bar).

•Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.

•Verify that all connections are secure before operating the unit.

•Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the controls.

Warnings

WARNING

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.

•Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure and disconnect all power sources.

SUCTION HAZARD

Powerful suction could cause serious injury.

•Never place hands near the pump fluid inlet when pump is operating or pressurized.

CARBON MONOXIDE HAZARD

Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon monoxide can cause death.

•Do not operate in an enclosed area.

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.

•Read MSDSs 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.

BATTERY SAFETY

The battery may leak, explode, cause burns, or cause an explosion if mishandled.

•Only use the battery type specified for use with the equipment. See Technical Data.

Lift Instructions

To avoid injury, always use designated Lift Locations when lifting the unit. When lifting the unit, only use ANSI approved slings and equipment rated for a minimum of 500 lb (227 kg). Always use ANSI approved equipment for securing the unit to transporting equipment.

1.When lifting sprayer, balance weight evenly across two straps/chains as shown.

3.Be sure straps/chains used for lifting are rated to support weight of sprayer: 500 lbs (227 kg).

4.Do not lift unit with only one strap secured across pump. This could put stress on frame and damage pump.
