USING YOUR SPRAYER

All material settles as it sits, so it is important to mix it thoroughly before you begin.

NOTE: Do not shake the material to mix it. This can

cause bubbles in the material which can result in a poor spray pattern. Always stir the

material gently but thoroughly before use.

Remove any skin that has formed on the top of the material. Do not mix the skin into the material If you do the skin will

break up and clog your sprayen

Using the 1-quart container

To use:

1. Fill container with the material to be sprayed.

2. Place a few drops of household oil down the intake and return openings in the pump housing.

Intake Filter -,

3. Push the suction set securely into the

intake opening on the bottom of the pump

housing. Make certain that the intake filter is I'_

in place on the suction set.

4. Thread the container securely to the

sprayer.

Using the optional suction extension

The suction extension inctudes a suction tube, tube fitting, locking collar, return cup, and a container clip. It allows you to attach the sprayer to a larger container such as a 1 or 5 gatlon

paint pail. This wilI decrease the material flow, so It will take longer to apply lhe same amount of material to the surface being sprayed.

To use:

1. Place a few drops of oil down the two holes in the gun.

Place the return cup under the

gun, lining up the indentation

in the side of the cup with the

intake port on the sprayer.

Slip the locking collar over the cup and thread into place. The return cup is necessary to catch any paint that is returned through the bypass opening below the paint pump,

4. Place a light coat of oil on the end of the tube fitting, then insert it securely into the intake port on the sprayer. Be sure it fits snugly, with no air leaks.

5. Push one end of the suction tube onto the tube fitting.

6. Slide the suction tube through the container

clip.

7. Push the imake hose onto tbe suction set

assembly. Make certain that the intake

filter is in place on the suction seL

8. Submerge the suction set assembly into the

Using the optional flexible extension

To use the optionai spray tip extension, follow the instructions

below.

1. Remove the spray tip. Be sure to leave the ,

atomizer valve in place.

2. Screw the end of the extension tube with the

plastic threads to the sprayer.

3. Remove the plastic protector from the

metal end of the extension. Be careful not to lose the auxiliary atomizer

head under the plastic protector.

4. Screw the spray tip onto the flex tube with the auxiliary atomizer head in place.

Selecting the proper tip

Your sprayer comes with a variety of spray tips depending on the model: a round t p, a w de ang e tip (op ional), and a stain tip (optional).

Wide angle tip

The wide angle tip produces a wide pattern th;_:_can be

adjusted horizontally or verticatly.

I WARNINGI

SKIN INJECTION HAZARD - Do not place any part of your body

in front of the spray tip. Spray pressure could cause skin

penetration, resulting in severe injury and possible amputation.

Leave the sprayer unplugged until it is time to spray.

To adjust:

1. Make sure the sprayer is unplugged.

2. Loosen the wide angle tip by turning the collar counterclockwise 1/4 turn.

3. Turn the tip guard so that it is pointing down for a horizontal pattern. Turn the tip guard so that it is pointing to the side for a vertical pattern.

The sprayer will leak from behind the spray tip if the swirl valve is not seated properly. If you notice material leaking from this

area:

1. Unplug lhe sprayer --Pump Housing immediately. Opening

2. Remove the soray, t p CoiFar by turning it

counterclockwise.

3. Remove the swirl valve and see it it needs to ,, SorayT O

be cleaned or replaced. Also check the piston SwirrValve housing opening for

any dirt or other obstruction a_d clean if necessary.

4. Put the swirl valve back in place, making sure it can seat properly without any obstruction.

5. Thread on the spray tip by turning it clockwise and tighten

it firmly by hand.

Use the wide angle tip for covering a large, flat surface. It

works well with most latex paints and stains. The wide angle tip is not recommended for use with oiFbased paints.

,-Locking

Round tips

The round tip produces a round pattern. Use a round tip if the

surface you are spraying is too smal_ for use with the wide angle tip.

The round tip comes in 3 sizes avai]able at your local retailer.

Use the size that works best for the type of material you are spraying. The color of the tip center indicates its size.

1. Brown (light materials) - .016 inch (0,4 mm) opening, This works best for stains, sealers, lacquers and water

proofers.

1. Blue (medium materials) - .023 inch (0.6ram) opening.

This size works best for oil-based materials.

2. Pir_k (heavy materials) - .031 inch (O.8mm) opening. This

all-purpose size works best for most materials.

Stain tip

The stain tip is an option incIuded with some models It has a specially designed opening for use with thin materials such as

thin stains, sealers and waterproofers, and can be adjusted to reduce overspray. If you did not receive a stain tip and will be spraying one of these materials, the tip can be purchased at your Iocai retailer.

The stain tip pattern is round with a fine spray. To adjust the spray pattern size and coarseness, turn the tip slightly

counterclockwise to narrow the pattern and make the spray

more coarse. Turn the tip slightly clockwise to widen the

pattern and make the spray more fine.

Horizontal Pattern Vertical Pattern

4. Tighten the tip firmly by hand.

NOTE: Make sure to tighten all spray tips firmly by

hand. If the spray tip is not tightened firmly enough, the sprayer could leak or the tip could

be damaged. Do not use a tool to tighten the spray tip. If the tip is too tight, it may be damaged.

CAUTION]

If material is leaking from the threads between the spray tip and the locking nut, turn off the sprayer immediately or the sprayer could be damaged.

SPRAYING

Priming the sprayer

If you are using the suction extension, you witl need to prime

the sprayer by removing air from the system. To prime:

1. Turn the flow knob fully counterclockwise to maximum.

2. Make certain the sprayer is plugged in.

3. Hold tr_esprayer below the level of the paint. This will speed the priming.

4. Squeeze the trigger and hold until all air is out of the system and material is flowing freely out of the sprayer tip.

This should take about 2 minutes.

I CAUTION I

Using the flow knob

Turning the flew knob counterclockwise increases the amount of material flow. Turning the flow knob clockwise decreases

the amount of 'T_ateria] flow. To adjust the pattern:

1. Turn the flow knob fully counterciockwise to maximum.

2. Squeeze the trigger and test the pattern on a piece of scrap wood or

cardboard.

3. Turn the flow knob clockwise until you have a good pattern, i

If you adjust the flow knob and power level and still cannot get a good pattern, you may need to thin the material you are using.

Measuring material thickness

The included viscosity/stir stick has one easyqo read indicator for all materials. To use:

1. Submerge the V-shaped end of the stick in the material and stir thoroughly.

2. Remove the stick from the materiai and Iet hang vertically

for 15 to 20 seconds.

If the material clears the V-shaped notch all the way up to the raised indicators or above within 15 to 20 seconds, the material is the right thickness. If it does not, the material may need thinning.

The suction set must remain completely submerged in the material. If it is not completely submerged and air is sucked into the system, the piston could seize. If the piston becomes seized, the sound the gun makes will change to a low hum and the gun will quickly become hot to the touch. Never run the sprayer when the piston is seized. Should this happen, clean the piston and the piston housing thoroughly using the cleanup procedures

found in this manual.

Adjusting the spray pattern

The spray pattern is controlled by the flow knob on the back of the sprayer and by the thickness of the material being sprayed. A bad spray pattern will concentrate the paint in the center of the spray and go on blotchy. A good spray pattern has an even amount of material throughout the pattern in a fine spray

and will go on smoothly.

Bad Spray Pattern

Always practice spraying on a piece of scrap wood or cardboard to test your spray pattern. Use the coverage rate recommended by the material manufacturer on the container.

NOTE: Always start without thinning the material, As

a general rule, only very thick latex materials require thinning,

Good Spray Pattern

Thinning the material

If you need to thin the material you are using, try Paint Easy TM Latex Paint Conditioner for latex paints, available from your

local retailer. It thins the paint by adding a specially

formulated material for a finer spray. Water wilI also work but it will dilute the material. For oil-based materials, use the

thinning agent recommended on the materiai container.

How to spray

Once you have achieved a good spray patfem on your test piece of wood or cardboard, it is time to begin spraying your work. The key to a good 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 sprayer at a constant distance from the surface. The best spraying cistance is 10 to

12 inches between the spray tip and the surface.

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

your wrist.

Do not flexwrist white sprayin T

Keep the sprayer perpendicular to the surface, otherwise one end of the pattern wilI be thicker than the other.

Aproximately.

Never tip the sprayer at more than a 45° angle when using

the small container. Material could get into the motor housing and damage the sprayer.

Overspray

Sprayers create a cloud of paint. Some of that cloud will spray past your intended object and also bounce off of it. Wind and air currents may cause this cloud to drift onto surfaces not

intended to be sprayed. You can control the amount of overspray and bounce-back by reducing your power setting

and adjusting your flow, but always make sure that you have a good spray pattern. Always test your pattern on a scrap piece of wood or cardboard, and make sure that you have drop cloths protecting anything not being sprayed. Anything you

don't want sprayed next to your spraying surface should be

covered.

The sprayer should be triggered by turning it or and off with each stroke. This will save paint and avoid pair*t buildup at the

end of the stroke. Do not trigger the sprayer continuously or

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.

CLEANUP

NOTE: The most important thing to know about your

sprayer is proper cleanup and maintenance.

Dried paints and stains act Iike glue and cause moving pieces

to stick, Taking the time to properly clean and maintain your sprayer heips it last longer and work right every' time.

Short-term cleanup

If you are leaving a project for a few hours or overnight:

1, Wipe the spray tip carefully before

storing for a few hours and again

before returning to spray.

If you are using the suction extension, you will also need to cover the materiai you

are using to avoid it from drying and forming a skin on top, For latex materials only. pour 1/2 cup of water siowly on the top of the material and

let stand. For other materials, seal the container with a piece of plastic with the suction extension still in the container.

6. Unplug the sprayer. 7 Remove the container and properly dispose of the

remaining solvent.

If you used the suction extension:

1. Unplug the sprayer.

2. Remove the suction set from the material container and submerge into a container of the solvent appropriate to

the type of material you sprayed.

3. Squeeze tI_etrigger and spray into a second container until the solvent coming through the sprayer is free of

material.

4. Unplug the sprayer.

5. Remove the suction set from the solvent.

6. Unlock the pump housing locking collar by turning it counterclockwise.

7. Pult the dual hose fitting out of the pump housing,

Cleaning the pump housing

1. Make certain the sprayer is unplugged,

2. Turn the spray tip counterclockwise until it

5. Insert the suction set into the intake (center) opening of the pump housing.

6. Thread the container onto the sprayer.

MAINTENANCE

Parts of your sprayer wear out with use and require regular replacement. They include the swirl valve. _3istonand spring.

These parts are not covered by your sprayer warranty.

More abrasive materials such as latex paints and stains cause

these parts to wear out faster than less abrasive materials such as oil-based paints and stains, thin stains and sealers.

Replacing the swirl valve

The swirl valve is shaped to cause the material to spin as it comes out of the sprayer. The spinning breaks the material up

into a fine spray. As more material goes through the swirl vaive, it wears out the valve and the shape of the valve changes. When it changes too much to prcduce a good spray

pattern, the vaJve needs to be replaced.
