CAUTION

Warnings

The following warnings include general safety information for this equipment. More specific warnings are included in the text where applicable.

WARNING

FIRE AND EXPLOSION HAZARD - FE CED/IND General

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 equipment and conductive objects in work area. See Grounding instructions.

• Use only grounded 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.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

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. 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.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• For professional use only.

• 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 use hoses to pull equipment.

• Comply with all applicable safety regulations.

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 MSDS’s 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.

Gun Selection

HVLP Guns

An HVLP gun is a high transfer efficiency gun which limits the air pressure at the aircap to 10 psi maximum. In some areas, an HVLP gun is required for compliance with environmental standards.

Air Caps

The chart below lists the air caps available for pressure feed, gravity, and siphon feed guns.

Typical Pattern

Spray Gun

Air Cap

Width*

in. (mm) Gun Feed

Compliant Guns

A compliant gun is a high transfer efficiency gun which has been tested to have a transfer efficiency greater than or equal to HVLP guns. The Graco compliant guns have no restrictions on aircap pressures, but the gun inlet pressure must remain under 29 psi (21 MPa 2.1 bar) to remain in compliance.

Airspray Guns

Excellent atomization and high production rates typically with some reduction in transfer efficiency.

Nozzle, Needle, and Tip Selection

The chart below lists the available nozzle sizes and required fluid needle and nozzles for the Delta Spray XT guns. The HVLP, Compliant, and Airspray guns all use the same nozzle design and fluid needles. When spraying high flow rates and high viscosity materials use the larger nozzle sizes and when spraying light materials or low flow rates, use the smaller nozzle sizes.

Setup

Flushing the gun

Flush the spray gun before putting any paint through the gun.

WAR NING

Read warnings, page 3. Follow Top and bottom feed guns installation, page 8.

1. To flush the gun, use a solvent that is compatible with paint to be sprayed. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to flush solvent through gun.

3. Install an air filter (G). See F

4. Use a 5/16 inch (7.9 mm) I.D. air hose to minimize excessive pressure drop in the hose.

5. Connect the air hose (D) to the 1/4 npsm gun air inlet (C).

FIG. 3

6. Connect the other end of the air hose (D) to a regulated air supply line.

3. To establish the correct fluid flow, turn the fluid adjustment knob (21) counterclockwise until no restriction of the trigger movement is felt, then turn out another half turn. When the knob is turned far enough, the trigger should be able to touch the gun handle when the gun is triggered.

4. Pressure feed only: Adjust fluid pressure to achieve desired fluid flow rate

5. To reduce fluid flow, turn the fluid adjustment knob (21) clockwise.

• If the fluid adjustment knob is turned clockwise all the way, the gun will emit only air.

• If you cannot achieve the correct fluid flow with the fluid adjustment knob, a different sized nozzle may be necessary. For smaller fluid flow, use the next size smaller nozzle. For a larger fluid flow, use the next size larger nozzle.

PRESSURIZED EQUIPMENT HAZARD

To avoid injury, never open the fluid adjustment knob (21) beyond the one half turn indicated in step 3 in Adjusting the Spray Pattern. If the red band on the knob stem (21) is visible, the knob is not adjusted correctly and could result in serious injury. Repeat step 3 in Adjusting the Spray
