Warnings

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 hazard symbols refer to procedure-specific risks. Refer back to these Warnings. Additional, prod-

uct-specific warnings may be found 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.

• 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-based materials or mineral
spirits-type material 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 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. 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.

PRESSURIZED ALUMINUM PARTS HAZARD

Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious chemical reaction and
equipment rupture. Failure to follow this warning can result in death, serious injury, or property damage.

• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing
such solvents.

• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for compat­ibility.

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. This 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

Troubleshooting

• Keep turbine air filters clean to allow full air
flow.

• Do not use an air hose that is too long to
provide sufficient atomization pressure.

• If droplets are still too large, reduce fluid.

Keep object being sprayed out of direct sunlight.
When spraying in warmer temperatures, use a
slower evaporating solvent or a reducer.

room temperature as possible. When spraying
on a cold surface, most paints will become too
thick to flow properly.

• Allow turbine to warm up a few minutes
before spraying.

• Store lacquer off concrete floors, at room
temperature.

• Apply lighter coats and allow for proper dry­ing time.

• Use a slower evaporating solvent or
reducer.

• Do not spray in windy conditions.

Clean all parts with a cleaning solvent; wipe with
a solvent rag and a clean rag. Replace rags as
needed. If problem persists, use a fish eye elim­inator.

• Move gun faster or decrease fluid flow.

• Maintain proper spraying distance, page 5.

• Reduce amount of thinner or use a faster
drying thinner.

• Apply fluid in lighter coats to allow for proper
