Warnings
Warnings
The following are general warnings related to the setup, use, grounding, maintenance and repair of this equipment. Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appearing in the body of the manual refer to these general warnings. When these symbols appear throughout the manual, refer back to these pages for a description of the specific hazard.
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 areas.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).
• When flammable liquid is used in or near sprayer or for flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.
• 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 objects in work area. See Grounding instructions.
• Use only conductive 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.
• Keep a fire extinguisher in the work area.
MOVING PARTS HAZARD
Moving parts can pinch 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 in this manual. Disconnect power or air supply.
SK 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 surgi- cal attention.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

Warnings
WARNING
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Use only grounded electrical outlets.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on sprayer and extension cords.
• Do not expose to rain. Store indoors.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. Read Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. Read
Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine Graco replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• 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.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
• Keep children and animals away from work area.
• Do not operate the unity when fatigued or under the influence of drugs or alcohol.
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:
• Protective eye wear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
• Gloves
• Hearing protection

Pressure Relief Procedure
SKIN INJECTION HAZARD
System pressure must be manually relieved to prevent system from starting or spraying accidentally. Fluid under high pressure can be injected through skin and cause serious injury.
To reduce risk of injury from injection, splashing fluid, or moving parts, follow Pressure Relief
Procedure whenever you:
• are instructed to relieve pressure
• stop spraying
• check or service any system equipment
• install or clean spray tip
1. Turn pressure control knob to zero.
2. Turn ON/OFF switch to OFF.
3. Unplug power supply cord.
4. Hold metal part of gun firmly to grounded metal pail. Trigger gun to relieve pressure.
5. Lock gun safety latch.
6. Open prime valve. Leave prime valve open until ready to spray again.
If suspected that spray tip or hose is completely clogged, or that pressure has not been fully relieved after following steps
above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Then clear tip or hose obstruction.
CAUTION
To reduce risk of pressure control malfunction:
• Use needle-nose pliers to disconnect wire.
Never pull on wire, pull on connector.
• Mate wire connectors properly. Center flat blade of insulated male connector in female connector.
• Route wires carefully to avoid interference with other connections of pressure control.
Do not pinch wires between cover and control box.
1. Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts are not normally provided with replacement assemblies.
ELECTRIC SHOCK HAZARD
MOVING PARTS HAZARD
HOT SURFACE HAZARD
To reduce risk of serious injury, including electric shock, do not touch moving or electrical parts with fingers or tools while testing repair.
Shut off and unplug sprayer when inspection is complete. Install all covers, guards, gaskets, screws, washers and shroud before operating sprayer.
2. Test repair after problem is corrected.
3. If sprayer does not operate properly, review repair procedure to verify procedure was done correctly. If necessary, see
Troubleshooting, page 10, for other
possible solutions.

WARNING
Improper installation or alteration of grounding plug results in risk of electric shock, fire or explosion that could cause serious injury or death.
1. Ultra Max II 695, 795 and 1095 100-200
Vac models require a 50/60 Hz, 15A circuit with a grounding receptacle. Ultra Max II
1595/Mark V 120 Vac models require a
50/60 Hz 20A circuit with a grounding receptacle; 220-240 Vac models require a
50/60 Hz, 10A circuit with a grounding receptacle.
3. 120 Vac: A 12 AWG, 3 wires with grounding prong, 300 ft (90 m) extension cord may be used. 220-240 Vac: You may use a 3-wire,
1.0 mm (12 AWG) (minimum) extension cord up to 90 m long. Long lengths reduce sprayer performance.

Troubleshooting
Electrical
Symptom: Sprayer does not run or stops running.
• Plug sprayer into correct voltage, grounded outlet
• Set power switch OFF for 30 seconds and then ON again. This ensures sprayer is in normal run mode.
• Turn pressure control knob clockwise 1/2 turn
• View digital display
WARNING
To avoid electrical shock or moving parts hazards when covers are removed for troubleshooting, wait 30 seconds after unplugging power cord for stored electricity to dissipate. Keep clear of electrical and moving parts during troubleshooting procedures.
If no digital display is available, use control board status light to troubleshoot problems: Turn
ON/OFF switch OFF, remove
TIA control cover and then turn power back ON. Observe status light.
Blinking LED total count equals digital error code i.e., two blinks equals E=02.
