Technical Data

PIPI-310

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

• 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 toyou.
• 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.
• I n 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.

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.

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

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.

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

Filling the Cup

• To open the cup, release the cup lock (A). Turn the cup to release it from the bracket (B).

• Place the cup onto a newspaper. Fill the cup with the prepared covering material.

• Align the suction pipe with regards to the job:
  To spray surfaces below your head set the suction pipe forward (C).
  To spray surfaces above your head set the suction pipe backwards (D).

• Set the cup into the cap. Close it with the bracket and block it tightening the lock.
  

Start Up

Volume Selector

• Turn the screw (A) to adjust the volume of the fluid to be sprayed.
• Turn the knob (B) to regulate the fan size to be sprayed.
• Turn the spryer (C) to change the fan angle.

• Start the compressor.
• Press the trigger (D) 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 flow.

Spraying Tips (1)

• To get good results, keep the gun always level and parallel to the surface (E). Keep the nozzle 7” – 9.8” and spray evenly from one side to the other and up and down. Do not spray in an angle (F). Otherwise the paint may run through the surface. Go in light and uniform passes.
  

Spraying Tips (2)

• Move the gun in a constant and uniform speed. Fast movements produce thin layer and slow movements produce thick layers.
• Apply one layer at a time. If needing a second layer read the manufacturer drying recommendations before applying a second layer. Remember, to get a better finish apply two thin layer is better than applying a thick layer only.
• When spraying small areas turn the adjusting screw to lessen the volume of the material to be applied. This way using too much paint is prevented and also you will not spray in excess.
• To assure a uniform application, when possible, do not pause while spraying an object.
• Do not tilt the paint gun in an angle higher than 45°
• When spraying large areas use a crossed pattern (A).

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 (B).

• 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 (C).
• 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 (D).
