WAGNER Control Spray Manual

Controls and Functions

Material Preparation

Note: Material to be sprayed may need to be strained to remove any impurities in the paint which may enter and clog the system. Impurities in the paint will give poor performance and a poor finish.

Thinning the material:
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.
Note: Only thin the material if absolutely necessary to improve spray performance. Optimal spray performance should be acheived simply by adjusting the various controls on the unit.
Do not thin with materials that have a flashpoint below 100°F (38°C). The material flashpoint should be shown on the material container.

To Prepare the Material:

1. Stir the spraying material thoroughly. Unscrew the cup from the spray gun.
   
2. Secure the thinning accessory to the side of the container as shown. The accessory should sit perfectly vertical.
3. Fill the container with spray material to the bottom of any of the notches on the accessory.
4. Add the appropriate thinning agent (Wagner Paint Easy or mineral spirits for solvent-based materials). For every notch that the fluid level in the container rises, the spray material is diluted by 10%.
   Note: It is recommended that the material be thinned in increments of 10%, but not more than the material manufacturer's recommendations.
   
5. After the material has been properly thinned and strained, fill the container to the top of the neck.
   

Assembly

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 in the 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.
  

• 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.
  

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)

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 100ºF (38ºC):

• 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.
   

If you cleaned the sprayer using mineral spirits, repeat steps 1-6 using warm, soapy water.
Move on to "Cleanup - Cleaning the nozzle", next page.

Cleanup (continued)

Cleaning the Gun
To Clean the Nozzle:

1. Make sure power cord is unplugged. Push the tab below the trigger, twist and separate the spray gun from the turbine.
   
2. Wipe the exterior of the cup and gun until clean.
   
3. Unscrew the nut and remove the air cap and nozzle.
   
4. Remove the parts as shown*. Clean all parts with a cleaning brush and the appropriate cleaning solution. Reassemble all parts when clean** (see "Nozzle Seal").
   
5. Clean the rear of the gun (d) with the appropriate cleaning solution. Use a thin layer of petroleum jelly to lubricate the O-ring (e). Reassemble the spray gun.
   

* Nozzle seal
The red nozzle seal may become stuck inside the 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. Improper installation will cause leakage and damage to the turbine.

Maintenance

Cleaning the Filters:

Before every use, you should inspect the air filters in the turbine to see if they are excessively dirty. If they are dirty, follow these steps to replace it.

never operate your unit without the air filters. Dirt could be sucked in and interfere with the function of the unit.

1. Unplug the spray gun. Remove the filter cover from the turbine by removing the two screws holding it in place.
2. Remove the dirty filters and replace with new ones. The smooth side of the air filter must be placed toward the turbine.
3. Secure the cover back onto the turbine.

Important Electrical Information

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A 14 gauge or 12 gauge cord is recommended. If an extension cord is to be used outdoors, it must be marked with the suffix W-A after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

Household use only. Intended for outdoor use OnLY with materials having flashpoint above 100ºF (38ºC).
