Pneumatic Requirements

  • For household jobs, it is possible to use 1.5 CV compressors with a 5.2 gallons’ deposit. For more demanding jobs, like bodywork, industry, etc., we recommend using 3 CV compressors with a 26.4 gallons’ deposit as minimum.
  • Use high-pressure hoses with the adequate length to do the job comfortably.
  • Dust and water condensation inside the compressor tank can cause a deficient finish in the surface to be painted. To prevent that possibility, install a regulating filter between the compressor and the gun.

Substances and Materials

  • The unit is designed to apply covering materials like paint, varnish, enamel, etc. These should have an ignition point not lower than 70 °F. Check the product can label or container.
  • Do not spray substances you are not familiar with and if their potential danger is unknown to you.
  • Do not spray flammable substances.
  • Use care with dangers originated by the sprayed substances. Read the text and information in the cans and containers or the manufacturer specifications.

Before operating the unit

  • The unit shall not be used in enclosed areas or explosive environments.
  • If working outdoors consider wind direction. Wind carries the covering to great distances, causes damages and makes the job difficult.
  • If working indoors, verify there is adequate ventilation.
  • The work area shall be free of any ignition source. Do not smoke while spraying or near the work area.
  • Wear a face mask and safety goggles when spraying. Prevents damaging lungs and eyes.
  • Wearing gloves and an overall is recommended to protect hands and clothes from the product when applying.

While operating the device

  • Never point the sprayer towards your body, passersby or animals.
  • Make sure that the equipment does not absorb any steam solvent.
  • In the event you need to pause during the application process, do not set the sprayer sideways. Hold it by the hook of somewhere for it be vertical.

After operating the unit

  • When finishing the job clean the gun perfectly to eliminate any product residue. Accumulations can damage the gun and cancel the Warranty.

Parts

Product Overview

Preparation

  • To make a good job, it is important to prepare the surface to be sprayed. Thin the paint or product to gain the right viscosity before applying.
  • Always double check the surface is free of dust, dirt or grease.
  • Make sure to cover with adhesive tape, some newspaper and/or plastic those areas that do not require spraying.
  • Paint or product to be sprayed shall be mixed perfectly before filling the jar to prevent they settle and to make them lump-free.
  • Before buying the product read the manufacturer recommendations

Thinning the material

  • Most paints are sold ready to be used with a brush. They need to be thinned before applying with a spray gun. Follow the manufacturer’s instructions to thin it.
  • Adding a thinner is recommended. Add 5% to 10% until reaching the right viscosity to apply the material.
  • Use the din 4 viscosity flow cup (not included) to determine right viscosity of the paint. Viscosity is determined by counting the seconds it takes for the material to be discharged into the measuring glass. The following table shows the recommended times for different products.
    Product| Second to discharge
    ---|---
    Water based Paint| 20 – 25
    Primer| 24 – 28
    Varnish| 20 – 25
    Oil Based Paint| 18 – 22
    Enamel Paint| 18 – 22
    Aluminum Paint| 22 – 25
    Automotive Sealant| 25 – 35
    Wood Sealant| 28 – 35
    Wood Preserver| Thinning is not Required
    Wood Stain

Viscosity Flow
If after thinning the product the dispersion capacity is too low, add thinner. Add slowly from 5 % to 10 % until the dispersion capacity meets your needs.

  • If the paint is too thick, the painted surface will be too rough (orange peel). If the paint is too liquid, there is risk of dripping.

Filling the Jar

  • Unscrew the paint gun jar.

  • Align the suction pipe suitable for the job:
    To spray horizontal objects set the suction pipe forward ( A ).
    Filling the Jar
    To spray surfaces above your head, set the suction pipe backwards ( B ).Filling the Jar

  • Set the jar onto a piece of newspaper. Pour the prepared covering material and tighten the jar firmly into the paint gun.

Start Up

Volume Selector

  • Turn the adjusting screw ( A ) in a counterclockwise direction to increase the volume of the material to be sprayed.
    Volume Selector

  • Turn the adjusting screw in a clockwise direction to diminish the volume of the material to be sprayed.

Start up

  • Start the compressor.
  • Press the trigger ( B ) to open the air flow and start suctioning the product from the jar. Point the paint gun towards a piece of cardboard until the spray flows.
  • Release the trigger to stop the spray.

Spraying Techniques

  • To get the best result keep the gun always level and parallel to the surface ( C ). Keep the nozzle 10” – 14”
    Spraying Techniques
    away from the surface and spray evenly from side to side and up and down. Do not spray in an angle otherwise the paint may run through the surface. Do soft and uniform passes.
    When spraying large surfaces use a crossed pattern ( D ).
    pattern

  • Move the gun with a steady and uniform speed. Fast movements produce thinner layers. Slow movements produce thicker layers.

  • Apply one layer at a time. In the event of needing a second layer read the drying recommendations from the product manufacturer before applying an extra layer. Remember that to get a better finish applying two thin layers is better than only one thick layer.

  • When spraying small areas turn the adjusting screw to lessen the volume of the material. This prevents using too much paint and over-spraying

  • To assure a uniform application, do not pause while spraying an object when possible.

  • Do not tilt the paint gun in an angle higher than 45°.

Maintenance

Cleansing and Care

  • It is very important to clean the spray gun thoroughly after each use.
    An inadequate cleansing can result in malfunctioning and will cancel the Warranty.

  • Turn the jar to remove it from the gun. Do not remove completely. Press the trigger to remove remaining product from inside the spray gun system ( A ).
    Cleansing and Care

  • Pour the remaining material into an adequate container.

  • Disconnect the paint gun hose.

  • Clean the jar, the gasket seal and the suction pipe thoroughly with a rag soaked with the solvent that is right for the product.

  • Disassemble the regulator, the sprayer, the nozzle and the needle. Clean them with a brush and solvent.

  • Clean the paint gun body with a piece of rag moistened with solvent.
    Do not immerse the gun in solvent. The gasket may get damaged.

  • When the parts are clean assemble back the spray gun.

  • Pour a small amount of solvent into the jar.

  • Connect the hose to the spray gun.

  • Start the compressor and spray into a container until getting clean solvent out through the nozzle.

Needle Seal

  • Use special care adjusting the needle seal. This is very important to obtain good results.
  • Adjust the needle seal using a wrench, not included ( B ).
  • Periodically check the seal to be sure it is not damaged.
    To gain access to the seal remove the needle and remove the seal pressing piece ( C ).
