Beginner’s Guide to Use Wagner Flexio 890 Paint Sprayer

Paint Sprayers

Setup

For the setup to be complete, you need to remove the items from the X-box power box. Pres the locking tabs on either side to lower the carry handle. Then, open the box to retrieve the air hose and handle assembly. Close the air hose retainer. Unwrap the power cord. Slide the sprayer’s power cord into the recess. Finally, remove your preferred spray nozzle.

Material preparation     

Thinning the material;

  • May be necessary depending on the spraying situation. When using the ispray nozzle, thinning may not be necessary. It may however be necessary when using the detail finish nozzle for a finer finish. Be sure to adjust material flow settings to fit the specific material needs.

To prepare your material;

  1. Stir the material thoroughly
  2. Unscrew the paint cup from the nozzle
  3. Thin and strain the material properly and fill the container. Do not attach the container yet.

Assembly

  • Insert the suction tube into the intake opening
  • Align the tube according to your spraying direction. If downwards, the angled end should point toward the front. If spraying upwards, the angled end should point toward the rear of the nozzle.
  • Screw the cup back to the nozzle carefully. Tighten firmly.

  • Align the nozzle’s arrow with the unlock symbol on the gun’s handle
  • Insert and twist the spray nozzle into the handle in the direction of the lock symbol. The tab found below the trigger will lock the two into place.
  • Insert the air hose in the power box through the air hose port.
  • Turn on the power box switch. Turn the handle switch on. This will enable the turbine to run.

Air and material control

Spray performance depends on factors such as air power, material flow and material thickness. You need to test different control settings to achieve the desired results.

X-boost power dial

This power dial adjusts the air pressure levels produced by the turbine. It is factory set at maximum and may need adjustment. A high air power results to faster coverage and smooth finish when using thick materials. Lowering the air power results to rougher finish. This is because the material gets larger drops when coming from the gun. Use the arrow on the dial to change settings. Thickest section=high, middle section=medium and thinnest section =low.

Material Flow Control

This determines the amount of material sprayed from the gun. With thick materials, start with highest setting and decrease to the desired level.

For thinner materials start with the low material setting. Increase to the desired level. The higher the flow setting, the faster you will need to work. This is to avoid drips and sags in the spray pattern.

Spray pattern and adjustment

The spray pattern can be adjusted with ease. Use the turning the air cup ears (detail finish). The adjustment ring (ispray) can also be used. Turn them to horizontal, vertical or diagonal positions. Always ensure that the black retaining ring is not loosened when changing spray patterns. The air cap can only be set diagonally when using the detail finish nozzle.

Proper spraying technique

Always ensure that you have masked the areas that you do not want to spray. It is advisable that you practice on a piece of wood if you are new to air assisted spraying.

Surface preparation

  1. Clean all the objects that need to be sprayed. Mask the areas that you do not want to spray.
  2. Spray area preparation
  3. Clean the spray area and ensure that it is dust free. This will avoid blowing dust to the freshly sprayer surface.

How to spray properly

  1. Do not pull the trigger if the turbine is not running. This results to leaking material in the nozzle.
  2. Position the gun perpendicular to the surface. Spray when at least 6 inches from the surface. It is advisable to use reduced air power and material flow.
  3. Spray parallel to the surface. Make smooth passes at a consistent speed. This helps avoid irregularities.
  4. Always start with a thin coat. The second coat should be heavier.
  5. Overlap each spray pass by at least 50% when spraying a large section. This ensures full coverage.
  6. Always trigger your gun after spray pass has begun. Release the trigger before stopping a pass. Keep the gun pointed squarely at the spray surface. Ensuring that passes overlap slightly to get the most consistent finish possible.

Cleanup

Before starting the cleaning process, ensure that you have the right cleaning solution. Use warm soapy water for latex materials and mineral spirit for oil-based materials. Avoid solvents that contain silicone.

Flushing The Unit

Turn handle and turbine switches off. Unplug power cord. Loosen but do not remove the material container. This is to relieve any pressure left in the system. Pull the trigger for the material in the spray nozzle to drain back to the container.

  1. Unscrew container and remove. Empty the remaining material.
  2. Pour an appropriate amount of the cleaning solution into the cup. (Mineral spirits ¼ and water ½)
  3. Attach your cup to the nozzle. Plug in the turbine. Turn the handle and turbine on.
  4. Choose a safe area and spray the cleaning solution. Shake the gun when spraying. This breaks the spray material particles.
  5. Turn the handle and turbine switches off. Unplug power cord. Turn the material container by ½ turn to loosen it. Pull the trigger to drain back the material.

To Clean The Nozzle

  1. Ensure that the cord is unplugged. Also, ensure that the air hose is not attached to the turbine.
  2. For the ispray nozzle, remove the adjustment ring from the connecting nut. Loosen the nut and remove the parts. Clean all the parts using a cleaning brush. Reassemble the parts once done.
  3. For the detail finish nozzle, remove the nozzle and the air cap. Remove the parts and clean them using a brush. Reassemble all the parts.
  4. Clean the air vent on the suction tube using a soft brush.
  5. Push the tab found below the trigger, twist and separate nozzle from the handle. Clean the nozzle with the right cleaning solution. Lubricate using a thin layer of petroleum.

Reassembly

  1. First, install the nozzle seal. The groove should be facing towards the nozzle.
  2. Insert the spray nozzle. Align the grove and notch and align the nozzle with the needle.
  3. Fix the air screen in the air cap. Put both of them on the nozzle and secure using the connecting nut. Ensure that the short tab on the nozzle in line with the short slot on the air cap.
  4. Snap the adjustment ring into the connecting ring. This enables the adjustment lever to be position on the air cap.
  5. Reassemble the spray gun.

Maintenance

Replacing the filter

Note: Inspect the air filter before every use. This will help you see if there is any dirt. Never operate the paint sprayer without the air filter.

  1. Remove the power box cover. Remove the filter cover by pressing the tab.
  2. Remove and replace the dirty filter. Place the smooth side of the filter towards the turbine. Secure the cover of the turbine.

Cleaning the air valve tube

  1. Pull the air tube from the nozzle. Remove the valve cover by screwing it off. Remove valve seal. Clean the parts with care. Remove any materials in the valve seal housing area.
  2. Place valve seal in the valve cover. Let the pin face into the tube.
  3. Turn the valve facing upside down. Screw on the sprayer’s valve cover from underneath ensuring that the seal is inside.
  4. Place the sprayer’s air tube on the valve cover and on the nipple at the nozzle
