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.

DANGER

• 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

CAUTION

• 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.

CAUTION

• If working indoors, verify there is adequate ventilation.

WARNING

• The work area shall be free of any ignition source. Do not smoke while spraying or near the work area. ****

CAUTION

• Wear a face mask and safety goggles when spraying. Prevents damaging lungs and eyes. ****
• Wearing gloves and an overall is recommended toprotect hands and clothes from the product when applying. ****

While operating the device

CAUTION

• Never point the sprayer towards your body, passersby or animals.
• Make sure that the equipment does not absorb any steam solvent.

CAUTION

• 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

WARNING

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

Parts

Preparation

• To get a good job done it is important to prepare the surface to be sprayed. Thin the paint of fluid to get the right viscosity before applying.
• Always confirm that the surface to spray is free of dust, dirt and grease.
• Be sure to cover those areas not needing to be sprayed. Use adhesive tape, newspaper and / or plastic.
• The paint or fluid to spray shall be twirled before filling up the cup to prevent it from settling. It shall be free of lumps or other particles.
• Always check the manufacturer’s recommendations regarding the fluid before purchasing.

Thinning the fluid

• Most paints are sold ready to apply and need to be thinned before being adequate to apply with a gun.
  Follow the fluid manufacturer’s instructions to thin adequately.

• We recommend using a thinner from 5 to 10 % until reaching the right viscosity to apply the fluid.

• Use the din 4 viscosity flow cup (not included) to determine the right viscosity of the paint. Viscosity is determined counting the seconds that takes the fluid to be discharged from the measuring cup. The following table show the time recommended for different products.
  Fluid| 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| Do not require thinner
  Wood Stain

• If after thinning the fluid the dispersion capacity is very low, add little by little more dilatant from 5 to 10 % until the dispersion capacity complies with the needs.
  

• If the paint is too thick, the painted surface will be rough (orange peel). If the paint is too fluid, there is risk it will drip.

Filling the Cup

• The cup must be mounted on the gun before filling it.
• Open the cup cap and pour the coating material properly thinned as indicated in the previous section.
• Close the cap to start spraying.

Start Up

Volume Selector

• Turn the screw (A) to adjust the volume of the fluid to be sprayed. Turning counterclockwise the volume diminishes and turning clockwise the volume increases.
• Turn the screw (B) to regulate the air inlet into the gun.
• Turn the knob (C) to regulate the fan size to be sprayed.
• Turn the spryer (D) to change the fan angle.

Spraying Techniques

• To get good results, always keep the gun leveled and parallel to the surface (F). Keep the nozzle 7.0” – 9.8” away from the surface and spray evenly from one side to the other and up and down. Do not spray in an angle, otherwise, the paint may run through the surface. Make soft and uniform passes. When spraying large areas use a crossed pattern (G).

• Displace the gun using a constant and uniform speed.
  Fast movements produce thin layers and slow movements produce thick layers.

• Apply one layer at a time. If you need another layer see the drying recommendations from the material manufacturer before applying a second layer. Remember that to get a better finish, applying two thin layers as opposed to only one thick layer.

• When spraying small areas turn the adjusting screw to reduce the volume of material to be applied. This way you avoid using too much paint and prevents from over-spraying.

• To assure a uniform application, when possible, avoid pausing while spraying an object.

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

Start up

• Start the compressor.
• Press the trigger (E) to open the air flow and starts suctioning the fluid from the cup. Aim the gun towards a piece of cardboard until the fluid mist is sprayed.
• Release the trigger to stop the mist flow.

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.

• Pour the remaining fluid into an adequate container.

• Without removing the jar press the trigger to remove all the fluid inside the system.

• 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 when adjusting the needle seal. It is important for a good job.
• Adjust the needle seal using the wrench (A).
• Periodically check the seal to double check is not damaged. To gain access to the seal remove the needle and remove the seal oppressive piece in the seal (B).
