To reduce the risks of fire or explosion, electrical shock and the injury to persons, read and understand all inst
included in this manual. Be
familiar with the controls and proper usage of the equipment.
Indicates a hazardous situa on which, if not avoided,
could result in death or serious injury.
HAZARD: EXPLOSION OR FIRE
Solvent and paint fumes can explode or ignite.
Severe injury or property damage can occur.
PREVENTION:
• Provide extensive exhaust and fresh air introduc
n to keep the air
within the spray area free from
n of
flammable vapors.
• Avoid all igni on sources such as sta c electric
sparks, open flames, pilot lights, electrical
appliances, and hot objects. Con
or
power cords or working light
switches can make sparks.
• Do not smoke in spray area.
• Fire
sher must be present and in good working order.
• Use only outdoors in a well-ve
ed area. Flammable vapors are
heavier than air. The turbine contains arcing parts that emit sparks and can
ignite vapors.
• Follow the material and solvent manufacturer’s warnings and
• Do not use materials with a flashpoint below 70°F
(21°C). Flashpoint is the temperature that a fluid can produce enough
vapors to ignite (see coa
g supplier).
• Plas c can cause sta c sparks. Never hang plas c to enclose the spray
area. Do not use
drop cloths when spraying flammable materials.
HAZARD: EXPLOSION HAZARD DUE TO
INCOMPATIBLE MATERIALS.
Will cause property damage or severe injury.
PREVENTION:
• Do not use materials containing bleach or
chlorine.
• Do not use halogenated hydrocarbon solvents such as bleach,
mildewcide, methylene chloride and 1,1,1--trichloroethane. They are not
compa
e with aluminum.
• Contact your coa
g supplier about the compa
lity of
material with aluminum.
HAZARD: HAZARDOUS VAPORS
Paints, solvents, insec cides, and other
materials can be harmful if inhaled or come in
contact with the body. Vapors can cause
severe nausea, fa
g, or poisoning.
PREVENTION:
• Use a respirator or mask if vapors can be
inhaled. Read all instruc ons supplied with
the mask to be sure it will provide the
necessary prote
.
• Wear
eyewear.
• Wear
clothing as required by coa
g manufacturer.
HAZARD: GENERAL
Can cause severe injury or property damage.
PREVENTION:
• Read all instruc ons and safety
before
equipment.
• Follow all appropriate local, state, and
codes
governing ven a
, fire preven on, and
• Use only manufacturer authorized parts. User assumes all
risks and liabili es when using parts that do not meet the
minimum specifica
s and safety devices of the turbine
manufacturer.
• Do not spray outdoors on windy days.
• Wear
clothing to keep paint off skin and hair.
• Never aim spray gun at any part of the body.
Household use only. Intended for outdoor use ONLY with
materials having flashpoint above 70oF (21oC).

Important Electrical Information
1. The tool plug must fit into the socket. The plug may not be modified in any form. Do not use adaptor plugs together with protective‐earthed tools.
Unmodified plugs and suitable sockets reduce the risk of an electric shock.
2. Avoid physical contact with earthed surfaces such as pipes, heating elements, stoves and refrigerators. The risk through electric shock increases if
your body is earthed.
3. Keep the equipment away from rain and moisture. The risk of an electric shock increases if water penetrates electrical equipment.
4. Do not misuse the mains lead by carrying the tool by the lead, hanging it from the lead or by pulling on the lead to remove the plug. Keep the lead
away from heat, oil, sharp edges or moving tool parts. Damaged or twisted leads increase the risk of an electric shock.
5. If you work outdoors, use only extension leads that are approved for outdoor use. The use of an extension lead that is suitable for outdoors reduces
the risk of an electric shock.

Material to be sprayed should always be strained to remove any
impurities in the paint which may enter and clog the system. Impurities in
the paint will give poor performance and a poor finish.
MATERIAL FLASH POINT MUST BE 70°F (21°C) OR
HIGHER.
Fill Container
1. Unscrew the cup from the spray gun.
2. After the material has been properly thinned and strained,
fill the container to the top of the neck.
3. Carefully screw the cup back onto the spray gun.
4
NEVER trigger the gun while adjusting the ears on
the air cap. NEVER point the spray gun at any part
of the body.
Material Flow Adjustment
Set the material volume by turning the regulator behind the trigger of the
spray gun.
Proper Spraying Technique
If spraying with an HVLP spray system is new or
unfamiliar to you, it is advisable to practice on a piece of
scrap wood or cardboard before beginning on your
intended workpiece.
Surface Preparation
All objects to be sprayed should be thoroughly cleaned before
spraying material on them. Areas not to be sprayed may, in
certain cases, need to be masked or covered.
Spray Area Preparation ‐ outdoor use only
The spray area must be clean and free of dust in order to avoid blowing
dust onto your freshly sprayed surface.
How to Spray Properly
• Position the spray gun perpendicular to and one (1) or more inches from
the spray surface, depending upon the spray
pattern size desired.
• Spray parallel to the surface with smooth passes at a
consistent speed as illustrated below. Doing this will help
avoid irregularities in the finish (i. e. runs and sags).
• Always apply a thin coat of material on the first pass and
allow to dry before applying a second, slightly heavier coat.
• The closer your sprayer is to the object being sprayed the
lower the overspray.
Even coat throughout
Keep stroke smooth and at an even speed
• When spraying, always trigger the spray gun after spray
pass has begun and release trigger before stopping the
pass. Always keep the gun pointed squarely at the spray
surface and overlap passes slightly to obtain the most
consistent and professional finish possible.
Light coat Heavy coat Light coat
Do not flex wrist while spraying.

Special cleanup instructions for use with
flammable solvents (must have a flashpoint above
70ºF (21ºC):
• Always flush spray gun outside.
• Area must be free of flammable vapors.
• Cleaning area must be well‐ventilated.
• DO NOT SUBMERGE Air Compressor!
1. Unplug the spray gun, and
trigger the spray gun so that
the material inside the spray
gun flows back into the
container.
2. Unscrew the container.
Empty any remaining material
back into the material
container.
3. Pour a small amount of the
appropriate cleaning solution
into the cup (warm, soapy
water for latex materials;
mineral spirits for oil‐based
materials). Clean cup and
properly dispose of
cleaning solution.
4. Refill the cup with NEW
cleaning solution.
5. Attach the cup to the gun and
plug in the sprayer.
6. Spray the solution through the
gun for two seconds in a safe
area. Spray again for two
seconds. Unplug the spray
gun, and trigger the spray gun
so that the material inside the
spray gun flows back into the
container.
7. Wipe the exterior of the cup
and gun until clean.
8. Unscrew the nut and
remove the air cap
and nozzle.
9. Clean the container,
suction tube, air cap
and nozzle with a
cleaning brush and
the appropriate
cleaning solution.
Never clean nozzle or air holes in the spray gun with
sharp metal objects. Do not use solvents or lubricants
containing silicone.
10. Turn both knobs on both sides
of the Air Compressor Assembly
to the “Unlock” position, pull and
separate the spray gun from the
Air Compressor Assembly.
11. (a) Clean the rear of the spray
gun with the appropriate cleaning
solution.
(b) Turn the suction tube
anti‐clockwise and pull the suction
tube downward to disassemble it
from the spray gun. Then clean the
suction tube with the appropriate
cleaning solution.
Attention! The Seal Ring (4) between Suction Tube 1(3) and Suction Tube
2 (5) must be put back into place after cleaning. Otherwise, some paint in
the container will be sucked into the air duct and interfere with the
function of the unit.
