Frequently Asked Questions - JS-910FA Cotech

What types of paint can I use with the Cotech JS-910FA spray gun?

You can use water- and solvent-based paints, clear lacquers, wood stains, primers, 2-component paints, impregnating agents, and rust inhibitors. Do not use emulsion paints, alkali-based or acid-based paints, or calcimine paints like whitewash.

How do I adjust the viscosity of the paint?

Thoroughly shake the can, then dip the viscosity cup into the paint and measure the time it takes to empty through the hole. Dilute if too thick. Follow the guidelines: for solvent-based primer 25-40 DIN-s, varnish 15-40, etc. Only use coatings with a flash point above 21 °C.

How do I change the spray pattern?

Undo the retaining ring, twist the nozzle to select vertical (side-to-side), horizontal (up-and-down), or round pattern, then tighten. Additionally, pull the spray pattern lever back for round or push forward for oval.

How do I clean the spray gun after use?

First, switch off the turbine and pour leftover paint back into its can. Clean the container and suction tube with a soft brush or cloth. Pour solvent or water into the container, screw it on, then spray onto a rag until clear. Disassemble the nozzle and paint needle, wash in solvent/water, and dry. Do not use metal tools.

What safety precautions should I take when using the spray gun?

Wear safety goggles, gloves, and a breathing mask. Ensure good ventilation and avoid sources of ignition. Never point the spray gun at yourself or others. Keep children away. Use only in well-ventilated areas.

How do I adjust the fluid flow?

Turn the fluid control knob on the back of the spray gun: anticlockwise to reduce flow, clockwise to increase flow. Test spray on scrap material to fine-tune.

What is the correct spraying technique?

Hold the spray gun 5-15 cm from the surface, keep it parallel, and move your arm in a wide sweeping motion. Start the stroke 15-20 cm before and end 15-20 cm after the workpiece to ensure even coverage.

What does HVLP mean?

HVLP stands for High Volume Low Pressure. It delivers a continuous volume of air at low pressure to atomize paint, minimizing overspray and paint runs while shortening drying time.

How do I clean the air filter?

Remove the air filter cap, extract the filter, clean it, and let it dry before replacing. Never operate the spray gun without the air filter. Unplug the machine before cleaning.

What is the maximum viscosity the spray gun can handle?

The maximum viscosity is 40 Din-s. If the paint is thicker than that, it may not spray properly and could clog the nozzle.

5. Preparations

5.1 Checking/adjusting the viscosity of the coating

Thoroughly shake the can of coating material before opening it. Spray paint normally needs to be diluted (we suggest that you test the paint before diluting it). Follow the manufacturer's recommendations for diluting the product. Ask your paint retailer for advice if you are unsure but remember to mention that you are using a HVLP spray gun. The thickness of paint is denoted by its viscosity and is measured by letting a certain amount of paint run through a hole of a certain diameter. The longer it takes for the paint to run through the hole, the higher the viscosity. The shorter the time, the lower the viscosity. Viscosity is given in seconds (DIN-seconds).

Warning! Only use spray coating with a flash point above 21 °C.

Measuring the viscosity

1. Shake the can containing the spray coating for a long time before measuring.
2. Dip the entire viscosity cup into the spray coating so that it fills completely.
3. Empty the viscosity cup and measure how long it takes for the fluid to run through the hole.
4. Dilute the paint if it is too thick and measure it again.

5.3 Preparing the object to be sprayed

• The quality of the finish will depend on how clean and smooth the surface is before it is sprayed. Remove any rust or old paint with sandpaper if necessary. Clean the surface of dust before spraying.
• Cover all surfaces that are not to be sprayed with plastic sheets or newspapers. Cover all hinges, screws, etc within the spraying area.

6. Settings

N.B. Ensure that the voltage marked on the product matches the power supply to be used.

• The spray gun can be set to horizontal, vertical or round spray patterns.

7. Spraying technique

• Always practice on a piece of scrap cardboard or similar before starting your project.
- Hold the spray gun 5–15 cm away from the surface of the object. Test to find a suitable distance before starting.
- Always begin your spray stroke 15–20 cm before the work and finish it 15–20 cm after the work. Move your arm in a wide sweeping motion (Fig. 10a).
- It is important that the spray gun is kept parallel to the surface (Fig. 10a), if not you will end up with more paint in the middle and less at the sides which leads to paint runs and poor finishes (Fig. 10b).

- Regularly check during spraying that there is no paint build up on the nozzle (2), as this prevents the spray gun from working properly. Clean if necessary.

Pausing from work

1. Switch the turbine off using the power switch (7).
2. Place the spray gun in the holder (13) on the turbine.

After finishing work

1. Switch off the turbine. Pull the trigger so that any paint left in the spray gun runs back into the container.
2. Unscrew the container and pour any leftover paint back into its can.
3. Clean as much paint as possible off the container and suction tube using a soft brush or cloth.
4. Pour solvent or water (depending on type of paint used) into the container and screw it back onto the spray gun. Warning! Only use solvent with a flash point above 21 °C.
5. Switch on the turbine and spray the solvent/water onto a rag or into a jar.
6. Spray a few times until no more paint residue comes out of the nozzle.
7. Switch off the turbine.
8. Unscrew the container and dry it, making sure that the surface of the joint is clean and free from paint residue.
9. Wipe the exterior of the spray gun with a cloth lightly moistened with solvent or water.
10. Unscrew the retaining ring (3) (with nozzle and adjuster) and remove the paint nozzle. Wash the loose components and paint needle in solvent or water. Do not use metal tools to clean the spray gun.
11. Reassemble the spray gun when it is clean and dry. N.B. The paint nozzle will only fit one way.

8. Care and maintenance

N.B. Unplug the machine from the power supply before cleaning or servicing it.

Cleaning: Clean the machine by wiping it with a soft cloth and maybe even a little mild detergent. Never use abrasive cleaning agents or solvents.

Clean the air filter.

1. Remove the cap (11), extract the air filter (10) and clean it.
2. Let the air filter dry before replacing it.

Never use the spray gun without the air filter.
