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, product-specific warnings 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 Ground-
ing 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-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 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 chlo-
ride, 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

Troubleshooting
• Keep turbine air filters clean to allow full air

• 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.

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 2.
• Reduce amount of thinner or use a faster
drying thinner.
• Apply fluid in lighter coats to allow for proper
evaporation.
• Use the recommended thinners.
• Follow the solutions for Orange Peel Finish,
