Technical Data

Pneumatic Requirements

• For household jobs, it is possible to use 1.5 CV compressors with a 25 liters’ deposit. For more demanding jobs, like bodywork, industry, etc., we recommend using 3 CV compressors with a 100-liter deposit as minimum.
• Use high-pressure hoses with the adequate length to do the job comfortably.

CAUTION

• 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

CAUTION

• 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.

WARNING

• 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.

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

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 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.

After operating the unit

Parts

Preparation

• Preparing the surface to be sprayed is important to carry out a good job. Thin the paint or product to gain the right viscosity before applying.
• Double check always the surface to be sprayed 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 settling and 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 paint gun. Follow the manufacturer’s instructions to correctly thin the material.
• 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 the paint right viscosity. 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.

Filling the Jar

• Unscrew the paint gun jar to fill up with paint. Close the cap to prevent spilling.
• The jar can easily be filled up during the paint process.
• The jar shall not be tilted more than 30° from the vertical to assure a continuous paint flow (A).
• In the event the job requires tilting the gun more than 30° you can adjust the jar to compensate the vertical and keep the paint flow running (B).

Product Second to discharge

Wood Stain

• 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.

Start-Up

Adjusts

CAUTION

• During the adjusting process and before applying the paint onto the work surface make some tests on scrap material until gaining the adequate paint flow.
• Turn the adjusting screw (A) in a counterclockwise direction to increase the volume of the material to be spayed.
• Turn the adjusting screw in a clockwise direction to diminish the volume of the material to be spayed.
• Turn the adjusting screw (B) to modify the fan pattern needed to apply the paint.
• Turn the adjusting screw (C) to modify the air flow needed to apply paint.
• Turn the sprayer (D) to determine the angle to apply the spray pattern.

Turning on

• Turn on the compressor.
• Press the trigger (E) to open the air flow and start suctioning the product from the jar. Aim the gun against a piece of cardboard until the spraying starts.
• Release the trigger to stop the spaying flow.

Spraying Techniques

• To gain best results keep the gun always parallel to the surface (F). Keep the nozzle 7.8” – 12” from the surface and spray in an even manner from one side to the other and upwards and downwards. Do not spray in an angle with regards to the surface. Pass softly and evenly. When spraying on large areas use the crossed pattern (G).
• Displace the gun using uniform and constant speed. Fast movements produce thin layers and slow movements, produce thick layers.
• Apply one layer at a time. If another layer is needed see the drying recommendations in the manufacturer product before applying a second layer. Keep in mind that to gain a better finish applying two thin layers is always better than one thick layer.
• When spraying small areas turn the adjusting screw to reduce the volume of material to be applied. This is helpful to use less paint and prevents from over-spaying.
• To assure applying evenly avoid pausing while spraying an object when possible.

Maintenance

Cleansing and Care

• It is very important to clean the paint gun thoroughly after each use.

WARNING

• Inadequate cleansing will result in malfunctioning and will cancel the Warranty.
• Without removing the jar press the trigger to remove all the product inside the system.
• 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.

CAUTION

• Do not immerse the gun in solvent. The gaskets may get damaged.
• When the parts are clean assemble back the paint gun.
• Pour a small amount of solvent into the jar. Connect the hose to the paint gun.
• Turn on 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 important to get a better job.
• Using the wrench adjust the needle seal (A).
• Check the seal often to assure it is not damaged. To gain access to the seal, remove the needle and remove the seal pressing part (B).
