GROUNDING INSTRUCTIONS

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper installation of the grounding plug can result in a risk of electric shock.

If repair or replacement of the cord or plug is necessary connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin.

Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

This product is for use on a nominal 120 volt circuit and has a grounding plug that looks like the plug illustrated below. Make sure that the product is connected to an outlet having the same configuration as the plug.

, do not

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. recommended.

3. Turn the motor switch to ON.

4. Turn the pressure control knob clockwise to between half and full pressure. You should see the paint move through the suction tube to the pump. Let the unit prime 1 to 2 minutes after paint begins to flow through the return tube.

Keep the spray gun at right angles to the surface. This means moving your entire arm back and forth rather than just flexing your wrist.

Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other.

Always reduce the pressure to zero before changing the position of the priming knob. Failure to do so may cause damage to the paint pump diaphragm.

If the pressure control knob is reduced to zero and the PRIME/SPRAY knob is still on SPRAY while the sprayer is operating, there will be high pressure in the hose and spray gun until the priming knob is turned to PRIME or until the spray gun is triggered to relieve the pressure.

SPRAYING

Spraying Technique

The key to a good paint job is an even coating over the entire surface. This is done by using even strokes. Keep your arm moving at a constant speed and keep the spray gun at a constant distance from the surface. The best spraying distance is 10 to 12 inches between the spray tip and the surface.

The spray gun should be triggered by turning it on and off with each stroke. This will save paint and avoid paint buildup at the end of the stroke. Do not trigger the gun during the middle of a stroke. This will result in an uneven spray and splotchy coverage.

Overlap each stroke by about 30%. This will ensure an even coating. When you stop painting, lock the gun trigger lock, turn the

If the Spray Tip Becomes Clogged

The spray gun is equipped with a reversible tip which allows you to blow out any particles of old paint or other contaminants that may obstruct the paint flow through the tip. If the spray pattern becomes distorted or stops completely while the gun is triggered on, follow these steps:

1. Release the trigger and lock the gun by turning the gun trigger lock so that it is parallel to the gun body.

2. Rotate the reversible tip cylinder arrow 180° so that the point of the arrow is toward the rear of the gun.

Cleaning Filter During Painting Process

Be sure to follow the pressure relief procedure when shutting the unit down for any purpose, including servicing or adjusting any part of the spray system, changing or cleaning spray tips, or preparing for cleanup.

This filter must be cleaned every time you use your sprayer.

When using thicker paints, the filter might need to be cleaned more often.

5. Reverse the tip so the arrow points forward again. Unlock the trigger and resume spraying.

Cleaning the Spray Gun Filter

The spray gun includes a filter to catch particles before they reach the spray tip. If this filter becomes clogged or obstructed it will reduce the flow of paint, changing the spray pattern and possibly damaging the filter

This filter must be cleaned daily old or contains hardened particles, then the filter should be cleaned approximately every 4 hours.

If the filter is not cleaned at the proper time, it will plug from the top down. When there is about 1 inch of filter that isn't plugged, the heavy flow of paint will blow pin holes in the filter allow unwanted particles to get into the spray tip, causing the spray tip to clog.

reassembling.

3. Test movement of the valve by pushing on it from the open end of the valve housing with a screwdriver or the eraser end of a pencil. It should move about 1/16 of an inch. If it does not move, it should be cleaned or replaced.

NOTE: The inlet valve must be oiled after every job.

This will reduce or eliminate priming problems the next time the sprayer is used.

4. Thoroughly clean the valve assembly with water or the appropriate solvent. Use a small brush.

5. If you have properly cleaned the valve and water drips out of the bottom, the valve is worn and needs to be replaced. A properly seated valve filled with water and held vertically will not drip.

6. Install a new or cleaned valve in the pump block and then fill the valve with light oil or solvent.

Removing and Cleaning the Outlet Valve

It may be necessary to remove and clean the outlet valve or to replace parts inside the valve worn out through normal use.

1. Remove the outlet valve body with a wrench.

NOTE: You will need to align the ridge on the seat with

the groove in the pump housing when reassembling.

6. Drop in the valve ball.

7. Insert the protector and spring and replace the valve body. Be sure that the O-ring is positioned properly and that the tongue on the cap fits inside the spring.

8. Tighten the valve body securely with an adjustable wrench. Do not overtighten.

NOTE: Wear on the ball is almost impossible to

detect visually. To test for a worn outlet valve assembly, turn the pressure control knob clockwise to its highest setting and run water only through the sprayer for 10 to 15 minutes without triggering the gun.

If the valve is defective, the end cap will get very hot to the touch. If it is functioning properly, it will stay approximately the same temperature as the water running through it.

Tightening the PRIME/SPRAY Knob

Sometimes the two allen screws holding the PRIME/SPRAY knob outer cover will vibrate loose. This allows the cover to turn without changing the valve setting. If this happens, loosen the screw with a 1/16 allen wrench, turn the knob to SPRAY and tighten the screw.

2. Remove and clean the ball stop and small spring inside the valve using a wire hook or tweezers. Replace the spring if it is broken or worn.
