Material Preparation

Note: Before spraying, the material being used may need to be thinned with the proper solvent as specified by the material manufacturer. Never exceed the thinning advice given by the coating manufacturer.

Do not use materials with a flashpoint below 100°F (38°C). Follow the instructions below.

To Prepare the Material:

1. Stir the spraying material thoroughly.

2. Dip the viscosity test cup completely into the spraying material.

3. Hold the test cup up and measure the time in seconds until the liquid empties out. This time is referred to below as Runout Time.
   Thinning Chart

4. Unscrew the cup from the nozzle.

5. After the material has been properly thinned and strained, fill the container to desired level.

Do not thin with materials that have a flashpoint below 100°F (38°C). The material flashpoint should be shown on the material container.

Assembly Instruction

Before you begin:
NEVER point the spray gun at any part of the body.

To Assemble:

IMPORTANT: Make sure the power cord is unplugged.

1. Insert the suction tube into the intake opening.
   

2. Align the suction tube –
   a. If you are going to be spraying in a downward direction, the angled end of the suction tube should be pointing toward the front of the gun.
   
   b. If you are going to be spraying in an upward direction, the angled end of the suction tube should be pointing toward the rear of the gun.
   
   Note: Make sure the suction tube is inserted as far as it will go to ensure a tight fit.
   IMPORTANT: Never tip the sprayer at more than a 45° angle. Material could get into the turbine and damage the sprayer.

3. Carefully screw the cup back onto the nozzle assembly. Tighten firmly.

4. Align the arrow on the nozzle with the “unlock” symbol on the turbine.

5. Insert and twist the nozzle into the turbine toward the “lock” symbol on the turbine.
   The tab below the trigger will lock the two pieces into place.
   

Spraying

Adjust Spray Pattern
The spray pattern shape is adjusted by turning the ears of the air cap to either the vertical, horizontal, or diagonal positions. The positions of the air cap and the corresponding spray pattern shapes are illustrated below.

Test each pattern and use whichever pattern is suitable for your application.

NEVER trigger the gun while adjusting the ears on the air cap. NEVER point the spray gun at any part of the body.

Horizontal pattern

• Use ‘up and down’ spraying motion

Vertical pattern

• Use ‘side to side’ spraying motion

Diagonal pattern

• Use ‘up and down’ or ‘side to side’ spraying motion
• For coating smaller areas, corners and edges

Material Flow Adjustment

Set the material volume by turning the regulator on the trigger of the spray gun

Proper Spraying Technique

If spraying with an HVLP spray system is new or unfamiliar to you, it is advisable to practice on a piece of scrap wood or cardboard before beginning on your intended workpiece.

Surface Preparation

All objects to be sprayed should be thoroughly cleaned before spraying material on them. Areas not to be sprayed may, in certain cases, need to be masked or covered.

Spray Area Preparation – outdoor use only

The spray area must be clean and free of dust in order to avoid blowing dust onto your freshly sprayed surface.

How to Spray Properly

Partially pulling the trigger will start the turbine, but no material will spray until the trigger is pulled fully. It is recommended that the trigger first be pulled partially in order to start the turbine before a spray pass is made.

• Position the spray gun perpendicular to and one (1) or more inches from the spray surface, depending upon the spray pattern size desired.

• Spray parallel to the surface with smooth passes at a consistent speed as illustrated below. Doing this will help avoid irregularities finish (i. e. runs and sags).

• Always apply a thin coat of material on the first pass and allow to dry before applying a second, slightly heavier coat.

• The closer your sprayer is to the object being sprayed the lower the overspray.
  
  Keep stroke smooth and at an even speed

• When spraying, always trigger the spray gun after spray pass has begun and release trigger before stopping the pass. Always keep the gun pointed squarely at the spray surface and overlap passes slightly to obtain the most consistent and professional finish possible.
  
  Do not flex wrist while spraying.

Cleanup

Flushing the unit

Before you begin:
When cleaning, use the appropriate cleaning solution (warm, soapy water for latex materials; mineral spirits for oil-based materials)

IMPORTANT: Never clean air cap or air holes in the
nozzle with sharp metal objects. Do not use solvents or lubricants containing silicone.

Special cleanup instructions for use with flammable solvents (must have a flashpoint above 100°F (38°C):

• Always flush spray gun outside.
• Area must be free of flammable vapors.
• Cleaning area must be well-ventilated.
• Do not submerge turbine!

To Flush the Unit:

1. Unplug the power cord. Loosen the material container by 1/2 turn, but do not remove it. This will relieve any pressure left over in the system.
   Pull the trigger so that the material inside the spray nozzle drains back into the container.

2. Unscrew the container and remove. Empty any remaining material back into the material container.

3. Pour a small amount of the appropriate cleaning solution into the cup (Water=1/2 full. Mineral spirits=1/4 full).

4. Attach the cup to the nozzle and plug in the sprayer.

5. Spray the cleaning solution into a safe area. While spraying, gently shake the spray gun. This slight agitation will help break up smaller particles of spray material.

6. Unplug the power cord. Loosen the material container by 1/2 turn, but do not remove it. This will relieve any pressure left over in the system.

Pull the trigger so that the material inside the spray nozzle drains back into the container.

IMPORTANT: If you cleaned the sprayer using mineral spirits, repeat steps 1-6 using warm, soapy water.

Cleanup

Cleaning the Nozzle To Clean the Nozzle:

1. Make sure power cord is unplugged. Push the tab below the trigger, twist and separate the nozzle from the turbine. Wipe the exterior of the cup and nozzle until clean.

2. Unscrew the nut and remove the air cap and nozzle.

3. Remove the parts as shown”. Clean all parts with a cleaning brush and the appropriate cleaning solution. Reassemble when clean**.

4. Clean the air vent (c) on the suction tube with a soft bristled cleaning brush.

5. Clean the rear of the nozzle (d) with the appropriate cleaning solution. Use a thin layer of petroleum jelly to lubricate the O-ring (e).

* Nozzle seal
The red nozzle seal may become stuck inside the spray nozzle when the nozzle is removed. If this occurs, make sure to pull it out.

It is important that the nozzle seal inside the nozzle be re-installed properly. Make sure the cup side of the seal (the side with the groove) is facing out towards the front of the nozzle
