The HVLP Edge gun is not intended to be used on an external compressor

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 hazard symbols refer to procedure-specificrisks. Refer back to these Warnings. Additional,product-specificwarnings may be found throughout the body of this manual where applicable.

WARNINGS

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.

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 working fire extinguisher in the work area.

When flammable liquid is sprayed or used for flushing or cleaning, keep sprayer at least 20 feet (6 meters) away from explosive vapors.

Do not clean with materials having flash points lower than 70° F (21° C). Use water-basedmaterials or mineralspirits-typematerial only. For complete information about your fluid, request the MSDS from the fluid distributor or retailer.

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 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. For complete information about your material, request MSDS forms from distributor or retailer.

Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

Do not alter or modify equipment.

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.

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.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or 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 eyewear and Hearing protection

Gloves, clothing and respirator as recommended by the fluid and solvent manufacturer
