Introduction

These spray guns are designed for use in a High Volume/Low Pressure (HVLP) painting system.
With an HVLP system, the highest quality professional finish can be achieved with little preparation or setup time. HVLP systems are not intended to replace airless systems. Instead, they are meant to compliment airless by improving the final finish on the substrate, minimizing waste, and reducing labor time. In addition to enhancing profitability, HVLP systems are compliant with the most stringent transfer efficiency requirements.
The HVLP spray guns described in this manual include the turbine cup gun, the turbine regulator gun, the turbine top feed gun, the regulator cup gun, and the regulator top feed gun.
Please review all the information contained in this manual before operating an HVLP system.

NOTE: The general operation and maintenance of each style of HVLP spray gun are the same. For illustration purposes, the turbine cup gun is pictured. However, any information specific to a style of gun is described where necessary. A
parts listing for each style of gun is included near the back of this manual.CAPSpray Maxum II HVLP Spray Guns - Air Flow

Using an HVLP Spray Gun

Preparing to Spray

  1. Release the cup locking lever and remove the cup.
  2. Fill the cup with the desired painting material. Make sure that the cup gasket is clean and in position.
  3. Place the cup on the spray gun and tighten the cup locking lever.
  4. Attach the air supply hose to the air inlet fitting at the bottom of the gun handle.
  5. Turn on the air supply.

Selecting a Spray Pattern
The spray pattern is adjusted by turning the air cap into either a vertical, horizontal, or diagonal position. To turn the air cap, grasp the two front tabs and twist. Never trigger the gun while adjusting the spray pattern.

CAPSpray Maxum II HVLP Spray Guns - Selecting a Spray
Pattern

Spray Pattern Size
To change the spray pattern size without changing the spray pattern shape, turn the air cap ring.

CAPSpray Maxum II HVLP Spray Guns - Spray Pattern SizeTurning the ring clockwise will make the pattern bigger.
Turning the ring counterclockwise will make the pattern smaller. As you reduce the spray pattern size, you will need to move closer to the surface.
Adjusting the Material and Air Flow
Each individual job and material may require slight adjustments in the material flow and air flow.
Turn the material flow adjustment knob clockwise for less fluid and counterclockwise for more fluid.

CAPSpray Maxum II HVLP Spray Guns - MaterialTurn the air flow adjustment knob to adjust for more or less airSet the mark on the knob straight up for maximum airflow.
Remember to test the spray on a piece of scrap wood or cardboard before using.

CAPSpray Maxum II HVLP Spray Guns - Adjustment Knob

Spraying

Hold the spray gun between 1 and 8 inches from the spraying surface, depending on the size of the spray pattern that you need. The closer to the surface you hold the gun, the smaller the spray pattern.
Keep the gun at right angles to the spraying surface in order to apply an even coat of material. If you keep the spray gun moving at a smooth and constant speed, the spray material is less likely to run or sag.

CAPSpray Maxum II HVLP Spray Guns - CorrectAlways squeeze the trigger of the spray gun after you begin your spray pass and release it before the pass is done. For best results, make the spray passes about 20 inches long and overlap each pass by 4 or 5 inches. Remember to keep the
gun at right angles to the spraying surface.

Adjusting the Swivel Tube
The adjustable swivel tube on your spray gun lets you get the most out of the material in your cup no matter at what angle you need to spray.
If you are holding your spray gun angled down, turn the swivel tube lever fully clockwise.
NOTE : An arrow on each side of the bridge indicates the direction that the swivel tube is pointing when the swivel tube lever is in its fully clockwise or fully counterclockwise position.

CAPSpray Maxum II HVLP Spray Guns - swivel tube leverIf you are holding the spray gun angled up, turn the swivel tube lever fully counterclockwise.

CAPSpray Maxum II HVLP Spray Guns - counterclockwise NOTE : The swivel tube lever is directly below the cup locking lever. The cup locking lever secures the cup to the spray gun.

Cleaning your Spray Gun

It is very important to clean your HVLP spray gun thoroughly after each use.

  1. Empty the spray material from the cup.

  2. Pour a small amount of the appropriate solvent in the cup and attach the cup to the spray gun.

  3. Shake and spray the gun in a well ventilated area.
    NOTE : Do not restrict the nozzle when cleaning. Back flushing of the system is not necessary.

  4. Repeat the steps above until the solvent appears clear.

  5. Wipe the exterior of the cup and the spray gun with the appropriate solvent until it is clean.

  6. Remove the needle, fluid nozzle, and air cap and clean them thoroughly. Make sure that the air holes and material passages are completely clean. Never use metal tools or picks to clean the air cap or nozzle.
    CAUTION
    Any attempt to remove the fluid inlet fitting will result in damage to the gun body and void the warranty.
    NOTE: Remove the needle packing only when replacing with a new needle packing. Do not remove the needle packing for cleaning.

  7. Disassemble, clean, and dry the check valve and air tubes after each use.
    CAUTION
    DO NOT clean the air tubes with hot solvents such as lacquer thinner. Hot solvents will damage the air tubes.

NOTE : Lubricate all of the threaded parts on the spray gun with petroleum jelly when you put them back together. This will help keep them working properly.

CAUTION

Do not use any lubricants containing silicone. Silicone can cause problems when used with some paints.

Maintenance

Perform the following maintenance procedures to keep your HVLP spray gun working properly.

Adjusting the Packing Nut
If material leaks from around or through the packing nut, readjust the packing nut.

  1. Disconnect the air hose from the air inlet and remove the cup assembly.
  2. Pull the trigger all the way back and hold.
  3. Tighten the packing nut using a 3/8 inch wrench until the needle remains retracted inside the nozzle when you release the trigger.
  4. Loosen the packing nut slowly until the needle moves freely back into position in the nozzle. Once you have adjusted the nut, reconnect the air hose and the cup assembly. Squeeze the trigger to see if the leaking has stopped. If it has not, make sure the packing nut is as tight as possible, while allowing the needle to move freely. If adjusting the packing nut does not stop the leak, replace the packing.

Replacing the Needle Packing and Air Valve Seals

NOTE : Remove the needle packing only when replacing with a new needle packing. Do not remove the needle packing for cleaning.
The needle packing and the air valve seals can be replaced separately. If you are replacing only one of them, use the appropriate steps from the following procedures.

Removing the Needle and Housing

  1. Disconnect the air hose from the air inlet.
  2. Remove the material hose or cup assembly.
  3. Remove the snap rings from the trigger retaining pins and slide the pins out of the gun.
  4. Remove the trigger.CAPSpray Maxum II HVLP Spray Guns - Trigger

Removing the Packing

  1. Remove the packing nut using a 3⁄8 inch wrench.
  2. Insert a long, narrow-bladed flathead screwdriver through the back of the gun and into the packing hole.
  3. Press the screwdriver firmly into the packing and turn counterclockwise. This should back the old packing out of the threaded hole. If it does not, push the screwdriver more firmly into the packing and try again. If this still does not remove the packing, use a pick tool to pull the packing out.CAPSpray Maxum II HVLP Spray Guns - Packing Hole

NOTE: Make sure all of the old packing is removed before installing the new packing.

Installing the New Packing and Reassembling the Gun

  1. Place the new packing into the packing hole.
  2. Thread the packing nut one turn into the packing hole. Do not tighten.
  3. Push the needle guide shaft through the back of the gun body and thread on the retaining nut.
  4. Grasp the material flow adjustment housing with the needle attached. Slide the needle with the spring and the rear air valve seal through the needle guide shaft and into the packing nut. Tighten the material flow adjustment housing securely using a wrench.
  5. Tighten the packing nut securely using a 3/8 inch wrench, then loosen the packing nut a quarter turn.
  6. Thread the air flow valve nut and air flow adjustment knob into the gun body and tighten into position.
  7. Assemble the trigger by inserting the retaining pin or pins and attaching the snap rings.
  8. Pull the trigger to make certain the needle moves freely. If the needle sticks, loosen the packing nut. If the packing leaks, tighten the packing nut.

Replacing the Check Valve, Valve Seal, and Air Tubes

The check valve is a one-way valve designed to allow air into the cup, pressurizing the cup’s contents. Because it is a oneway valve, it prevents paint from seeping up the air tube into the air passages of the gun. It also eliminates any delay in material flow when the gun is triggered by maintaining pressure in the cup.
The check valve rotates open easily for cleaning. It contains a valve seal that can be removed and cleaned with soap and water for waterborne materials or a compatible solvent for other materials.
To replace the check valve, the valve seal, and/or the air tubes:

  1. Pull the lower air tube from the bottom of the check valve.

  2. Pull the check valve from the upper air tube.

  3. Unscrew the two halves of the check valve.

  4. Remove the worn valve seal.

  5. Clean the check valve body with a solvent appropriate to the type of material being used.
    NOTE: Thoroughly clean the inside of the top half of the check valve but do not scratch it.

  6. Insert a new valve seal, stem up, into the top of the check valve as shown.

  7. Tighten the two halves of the check valve together.

  8. Insert the top of the check valve into the upper air tube.
    NOTE : Insert the check valve into the air tube so that the arrow on the valve points toward the gun.

  9. If the lower air tube is too long, trim the tube so that it fits the gun.

  10. Push the lower air tube onto the bottom of the check valve.

NOTE: Make sure to attach the shorter air tube to the gun fitting and the longer air tube to the cup lid air nipple.

Replacing the Cup Gasket

The cup gasket must be replaced periodically due to normal wear. It is important to inspect the cup gasket during each cleaning.

  1. Release the cup locking lever.
  2. Hold the cup and twist the spray gun in the direction indicated by the arrows on the bridge.
  3. Lift the spray gun away from the cup.
  4. Pull the worn cup gasket out of the lid.
  5. Press a new cup gasket into the lid.
  6. Place the spray gun onto the top of the cup.CAPSpray Maxum II HVLP Spray Guns - Cup Locking
  7. Turn the spray gun opposite the direction indicated by the arrows on the bridge until the pegs on the cup are in the notches of the bridge.
  8. Tighten the cup locking lever.

Converting to a Single Pin Trigger

The trigger on your HVLP spray gun can be converted to a single pin setup for a softer pull. Trigger pull is reduced by removing the upper trigger pin and operating the gun with only the lower trigger pin in place. This setup reduces finger fatigue and provides greater control when spraying thin, light viscosity materials such as stains, varnishes, and sealers.

  1. Remove the retaining clip on the upper trigger pin by placing the flat edge of a screwdriver between the clip and the pin and gently prying it off.
  2. Pull the trigger pin out from the opposite side of the gun.CAPSpray Maxum II HVLP Spray Guns - Single Pin

Using a Pressure Feed System

To increase spray time between material refills, your HVLP spray gun can be connected to a larger material pressure pot and air compressor.
Converting the Gun to Pressure Feed

Before using a pressure feed system, the spray gun must be converted to a pressure fed gun.

  1. Loosen the retaining nut using a wrench and remove the one quart cup assembly.
  2. Pull the air tube off of the air tube fitting on the spray gun. CAPSpray Maxum II HVLP Spray Guns - Cup Assembly
  3. Remove the air tube fitting using a wrench.
  4. Thread the set screw into the air tube fitting location and tighten into place.CAPSpray Maxum II HVLP Spray Guns - Set Screw

Connecting to a Pressure Pot or Two Quart System

  1. Connect the compressor air hose to the pressure pot inlet.CAPSpray Maxum II HVLP Spray Guns - Pressure Pot Inlet
  2. Thread one end of the material hose onto the pressure pot outlet and tighten.
  3. Thread the other end of the material hose onto the spray gun fluid inlet and tighten.CAPSpray Maxum II HVLP Spray Guns - Pressure Pot Outlet

Using the Top Feed Gun

The top feed HVLP spray gun is designed for use in special applications such as spraying in confined areas. The position of the cup gives the top feed gun the ability to spray downward and overhead.
When spraying with the top feed gun, remember the following tips for the best results. Keep the cup level when spraying at an angle. The special fluid inlet fitting on the gun allows the cup to rotate to remain level when the gun is at an angle.
Keep the cup pressurized at all times when spraying. Attempting to gravity feed the material will slow or stop the flow of material at the nozzle.CAPSpray Maxum II HVLP Spray Guns - Feed Gun

Converting the Gun to a Regulator Gun

Your HVLP spray gun can be converted to connect directly to existing high pressure air systems with the addition of a regulator assembly.

  1. Remove the air inlet fitting at the bottom of the gun handle using a wrench.
  2. Thread the fitting on the regulator assembly into the air inlet at the bottom of the gun handle and tighten.CAPSpray Maxum II HVLP Spray Guns - tighten
  3. Attach the air hose from the existing high pressure air system to the regulator assembly.
  4. Set the pressure gauge on the regulator assembly to the appropriate setting for the coating being sprayed.

NOTE : Standard air caps require an air flow of 15 –25 SCFM. Low air flow air caps are available for the regulator gun to use with smaller air compressors. See “Optional Accessories” for the part numbers.

Converting the gun from NonBleeder to Bleeder

Your HVLP spray gun can be converted from a non-bleeder to a bleeder setup. Bleeder setup provides more atomizing power for higher viscosity materials, such as latex and enamels. Bleeder setup can make it easier to spray in confined spaces, such as inside cabinets, because the air hose is moved to the back of the gun.

To convert a spray gun to bleeder setup:

  1. Remove the air flow adjustment knob from the rear of the gun using a wrench.
  2. Remove the air inlet fitting from the bottom of the gun handle using a wrench.
  3. Thread the air inlet fitting into the air flow adjustment knob location at the rear of the gun. Secure the fitting in place.CAPSpray Maxum II HVLP Spray Guns - Fitting
  4. Thread the air inlet plug (shipped loose with the gun literature pack) into the air inlet at the bottom of the gun handle. Secure the plug in place.
  5. Attach the air hose to the relocated air inlet fitting.
    NOTE: In bleeder setup, the removal of the air flow adjustment knob causes the air supply to be on at all times when the air hose is attached to the gun.

Choosing a Projector Set

Your HVLP spray gun should be fitted with the proper projector set for the type of work you will be performing. A projector set consists of a needle assembly, a fluid nozzle, and an air cap.

CAPSpray Maxum II HVLP Spray Guns - Needle AssemblyYou should choose a projector set based on two things: the type of material to be sprayed and the finish desired.
The chart on the following page should help you to make the right choice.

Material Reduction/Projector Set Chart

Before spraying, the material being used must be thinned with an appropriate solvent and the proper projector set must be installed. It is always best to follow the material manufacturers recommendations and thinning procedures.
There are two simple methods of measuring the proper thickness of a material:

  1. Dip a paint stick into the material and remove it, watching carefully as the material runs off. When the material begins to form drops, the drops should fall about 1 second apart.
  2. Use a viscosity cup (P/N 0153165). Dip the cup into the material and remove it. Use a watch or clock to time how long the material drains from the cup in a continuous stream. Once the continuous stream breaks, stop timing and refer to the table below. Add the appropriate solvent and continue testing until the proper thickness is reached for the type of material you are using.
