1. SAFETY INFORMATION
• Read all safety information before operating the equipment. Save these instructions
To reduce the risks of fire or explosion, electrical shock and the injury to persons, read and understand
all instructions included in this manual. Be familiar with the controls and proper usage of the equipment.
Indicates a hazardous situation 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 introduction to keep the air within the spray area free from
accumulation of flammable vapors.
• Avoid all ignition sources such as static electric sparks, open flames, pilot lights, electrical
appliances, and hot objects. Connecting or disconnecting power cords or working light switches
can make sparks.
• Do not smoke in spray area.
• Fire extinguisher must be present and in good working order.
• Use only outdoors in a well-ventilated area. Flammable vapors are often heavier than air. The
turbine contains arcing parts that emit sparks and can ignite vapors.
• Follow the material and solvent manufacturer’s warnings and instructions.
• 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 coating supplier).
• Plastic can cause static sparks. Never hang plastic to enclose the spray area. Do not use plastic
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 compatible with aluminum.
• Contact your coating supplier about the compatibility of material with aluminum.
HAZARD: HAZARDOUS VAPORS
Paints, solvents, insecticides, and other materials can be harmful if inhaled or come in contact with
the body. Vapors can cause severe nausea, fainting, or poisoning.
PREVENTION:
• Use a respirator or mask if vapors can be inhaled. Read all instructions supplied with the mask to
be sure it will provide the necessary protection.
• Wear protective eyewear.
• Wear protective clothing as required by coating manufacturer.
HAZARD: GENERAL
Can cause severe injury or property damage.
PREVENTION:
• Read all instructions and safety precautions before operating equipment.
• Follow all appropriate local, state, and national codes governing ventilation, fire prevention, and
operation.
• Use only manufacturer authorized parts. User assumes all risks and liabilities when using parts
that do not meet the minimum specifications and safety devices of the turbine
manufacturer.
6. TROUBLESHOOTING
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.
5. MAINTENANCE
You should inspect the air filter in the Air Compressor Assembly to see if it is excessively dirty. If it is
dirty, follow the steps below to replace it.
1. Unplug the spray gun. Remove the filter cover with a tool (such as a flat screw driver)
2. Remove the dirty filters and replace with new ones.
3. Secure the cover back onto the turbine.
Never operate your unit without the air filters. Dirt could be sucked in and interfere with the function
of the unit.
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 lubri-
cants 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.
Do not flex wrist while spraying.
4. CLEANUP
Cleaning the Spray Gun
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.
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, depen-
ding 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
Spraying The spray pattern shape is adjusted by turning the ears of the air cap to either the vertical,
horizontal, or diagonal positions. The positions of the air cap and the corresponding spray pattern
shapes are illustrated below. Test each pattern and use whichever pattern is suitable for your appli-
cation.
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.
• Do not spray outdoors on windy days.
• Wear protective 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).
• Read all safety information before operating the equipment. Save these instructions
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 refrige-
rators. 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.
2. COMPONENTS
3. SETUP
1. Turn both knobs on both sides of the Air Compressor Assembly to the “Unlock” position, and
Insert the spray gun into the Air Compressor Assembly into place,
2. Turn both knobs on both sides of the Air Compressor Assembly to the “Lock” position to lock the
two pieces into place.
Aligning the Suction Tube If you are going to be spraying in a downward direction, the angled end of
the suction tube should be pointing toward the front of the gun.
If you are going to be spraying in an upward direction, the angled end of the suction tube should be
pointing toward the rear of the gun.
By pointing the suction tube in the proper direction, you will not have to refill the container as often..
Material Preparation Before spraying, the material being used may need to be thinned with the
proper solvent as specified by the material manufacturer. Never exceed the thinning advice given by
the coating manufacturer. Do not use materials with a flashpoint below 70°F (21°C). Follow the
instructions below.
1. Stir the spraying material thoroughly before measuring viscosity.
2. Dip the viscosity test cup completely into the spraying material.
3. Hold the test cup up and measure the time in seconds until the liquid empties out. This time is
referred to below as Runout Time.
