GROUNDING INSTRUCTIONS
The product must be grounded. In the event of an electrical short
circuit, grounding reduces the risk of electrical 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 appropriate
outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
DANGER - Improper use of the grounding plug can result in a risk
of electric shock.
If repair or replacement of the cord or plug is necessary, do not
connect the grounding wire to either flat blade terminal. The
grounding wire has green insulation, with or without yellow
stripes.
Check with a qualified electrician or serviceman if the grounding
instructions are not completely understood or if in doubt as to
whether the product is properly grounded. Do not modify the plug
provided. If it will not fit the outlet, have a qualified electrician
install a proper outlet.
This product is for use on a nominal 120 volt circuit and has a
grounding plug that looks like the plug illustrated in Figure A.
Make sure the product is connected to an outlet having the same
configuration as the plug. A temporary adapter which looks like
the adapter illustrated in Figures B and C may be used to connect
the plug to a two-pole receptacle as shown in Figure B if a
properly grounded outlet is not available. The temporary adapter
should only be used until a properly grounded outlet (Figure A)
can be installed by a qualified electrician. The green colored rigid
ear lug or the like extending from the adapter must be connected
to a permanent ground such as a properly grounded outlet box
cover. Whenever the adapter is used, it must be held in place by
a metal screw.
EXTENSION CORDS
Use only a three-pronged 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 UL/ETL/CSA listed
and is in good condition. When using an extension cord, be sure
to use one heavy enough for the current - for lengths less than
18 feet, use a No. 18 AWG. or heavier; for lengths more than 18
feet, use No. 16 AWG. If in doubt, use a heavier gauge. An
undersized cord will cause a drop in line voltage resulting in loss
of power and overheating.
STORAGE
Make sure unit is clean and dry before storing. Store in a dry
location. To prevent damage, the electrical cord should not be
crimped during storage
.
Attention: The temporary adapter shown in sketch B and C is not for use in
Canada. Use only a grounded outlet with this unit.

PRACTICE FIRST
Practice spraying water on newspaper or cardboard. This will give you the feel of the
sprayer and all of its features. Follow the instructions for adjusting to the proper spray
pattern.
1. Check the following: (See Figure A.)
• Spray tip is screwed on tightly.
• Remove container from cylinder housing.
• Pick-up tube inserted tightly into the longer port of the cylinder housing.
2. Fill container with water. Refasten container to cylinder housing.
3. Plug in the sprayer.
4. Press switch. Allow a few seconds for the unit to spray water.
5. As you spray, adjust the volume control knob and notice the difference in spray volume
and spray pattern. Adjust the volume control knob until you get the best possible spray
pattern.
NOTE: The best distance for spraying is 10 in. to 12 in. Too far away may cause
excessive overspraying and too close may cause excessive spray build-up (runs). See
Figure B.
6. Keep a stiff wrist. Do not arch your wrist at the beginning or the end of the stroke. Do
not stop the motion of the unit while spraying. The path of the sprayer must pass
beyond the area being sprayed, and the switch must be triggered on and off as the
sprayer passes into and out of the spraying area. See Figure C.
NOTE: Stopping the motion of the sprayer or swinging into a new stroke pattern while
spray is being delivered will result in heavy spray build-up at the edges of the stroke.
THINNING MATERIALS
In order for your sprayer to operate properly it is important to make sure the stain or paint
is thin enough to be sprayed. Thinning should be followed per the stain or paint
manufacturer’s guidelines. Because materials differ from brand to brand, this guide can
offer only general information. The final guide to correctly thinned stain or paint is
achieving the proper spray pattern as shown in Figure D. Always follow the coverage rate
recommended by the manufacturer regardless of the thinning required. Because there is a
variance in viscosity between paint and stain brands, it might be necessary to thin five to
15 percent to achieve optimum spray pattern.
NOTES:
• Use the correct spray tip for the material being used. (See spray tip selection chart
below.)
• Be sure pick-up tube is tightly inserted in correct intake port.
• Thin material to proper viscosity, per manufacturer’s requirements.
• Before each use, check spray tip and atomizer valve for wear.
• Always thoroughly clean and oil the sprayer after each use.
• If you hear a low humming sound, immediately stop pressing the trigger.
See TROUBLESHOOTING.
• Thin material may spray better at low power setting.
• Old stain or paint should be strained before using.
• Stir stain or paint slowly. To prevent air bubbles, do not shake stain or paint.

TWO-SPEED CONTROL
“Low” is the better setting when you need to paint slowly—doing tighter, detail work,
for example, when you are spraying thin materials (e.g., semi-transparent stain). The
“High” setting sprays more paint, so use this to quickly paint larger, more open areas.
(See Figure E.)
SPRAYING INSTRUCTIONS
Caution: Do not twist electrical cord. Make sure heavy objects are not placed on it. Keep
electrical cord away from heat and sharp objects. To avoid a tripping hazard, make sure
cord is not in a heavy traffic area. Do not use the cord if it is damaged.
Use appropriate breathing protection, eye protection, gloves and clothing.
1. Empty container thoroughly and ensure the container is dry.
2. Deposit the stain or paint material into container.
3. Begin spraying by pressing the switch. Adjust the volume control knob to get the best
spray pattern. A pattern with heavy spray in center (Figure F1) means the pressure is
too low. Adjust the volume control knob by turning counterclockwise to increase
pressure. A correct spray pattern looks like the one shown in Figure F2. The stain or
paint should be evenly spread over the surface.
4. If the spray pattern is still not correct, refer to TROUBLESHOOTING.
5. Hold the sprayer 10 to 12 inches from the surface to be stained or painted. Keep the
sprayer parallel to the ground without pointing it up or down. See Figure G.
NOTE: TILTING THE SPRAYER IS NOT RECOMMENDED.
NOTE: TO AVOID RUNS AND SAGS, DO NOT SPEED UP OR SLOW DOWN WHILE
MOVING THE SPRAYER.
6. Overlap each stroke about 1/3 of the spray pattern.
7. To spray inside corners, spray the adjoining walls or surface first. The overspray will
stain or paint the corner.
8. When you spray an outside corner, point the spray tip of the sprayer towards the
surface. This will prevent stain or paint from being sprayed past the corner and onto
surfaces you do not want stained or painted.
IMPORTANT
Should a low humming sound and/or irregular spray pattern occur while spraying,
immediately remove plug from electrical source and thoroughly clean the sprayer. This will
prevent the motor from overheating and causing damage to the sprayer. See CLEAN UP
INSTRUCTIONS.
NOTE: If you stop spraying for 30 minutes or longer; before continuing, retest the spray
pattern by spraying on newspaper or cardboard. If you are unable to adjust the spray
pattern properly, it is possible the stain or paint material has started to dry. If this
happens, clean the sprayer. See CLEAN UP INSTRUCTIONS.
NOTE: The small vent hole on the top of the cylinder housing must be kept clean. If the
stain or paint material should dry and clog the hole in the cylinder housing, your
sprayer will not function properly. See CLEAN UP INSTRUCTIONS.
NOTE: If the spray pattern is still not correct, a thorough cleaning of the spray tip,
atomizer valve assembly, and pick-up tube may be required. To maintain correct
spraying, it may be necessary to clean the unit after dispensing five to nine gallons of
paint or stain. After cleaning, reassemble the parts.

STEP ONE: CLEAN UP INSTRUCTIONS
NOTE: Proper clean up is essential to keep your sprayer in optimum working condition.
Dried by-products act like glue and will cause moving parts to stick. Failure to properly
clean your sprayer will damage the unit. Taking the time to clean your sprayer
immediately after use will help your sprayer last longer and work correctly. If you are
finished with the project or are not going to use the sprayer within the day, you must
follow these instructions for proper clean up. Never store the sprayer longer than 30
minutes without cleaning.
1. Unplug your sprayer from the electrical outlet.
2. Empty any remaining (stain or paint) material from the container.
3. Fill container approximately 1/2 full with appropriate cleaning solution. For latex, use
warm soapy water; for oil-based, use a cleaning solution recommended by the material
manufacturer. See Figure L.
4. Plug sprayer into an electrical outlet.
5. Press the switch of the sprayer until the cleaning solution passes through the spray
nozzle for several seconds.
6. Remove container and properly discard the cleaning solution.
7. Unplug the sprayer from the electrical outlet.
STEP TWO: CLEAN UP INSTRUCTIONS FOR THE CYLINDER HOUSING
1. Unplug your sprayer from the electrical outlet.
2. Press the QUICK RELEASE buttons on both sides of the sprayer. Grasp the container
with one hand and, with the other hand, slide out the QUICK RELEASE cartridge. See
Figure M.
3. Pull out pick-up tube.
4. Remove all the parts from the QUICK RELEASE pump housing cartridge. See Figure N.
5. Depending on the material used, some residue may remain on the sprayer parts.
Remove any remaining residue with the cleaning brush. See Figure O.
6. Lubricate all moving parts with lightweight oil. (Included, or use WD40
®
, 3-in-One®oil,
or similar product.)
7. Reassemble the QUICK RELEASE pump housing cartridge parts.
8. Reinsert the cylinder housing into the housing. You will hear a click when the cylinder
housing is engaged into the housing. See Figure P.
9. Reassemble the pick-up tube and the container.
LUBRICATION INSTRUCTIONS
Lubricating the sprayer prior to storage is extremely important to maximize the life of the
cylinder housing and its components.
1. Unplug your sprayer from the electrical outlet.
2. Empty any remaining (stain or paint) material from the container, remove the pick-up
tube and clean.
3. Plug the sprayer into the electrical outlet.
4. Turn the sprayer upside down.
5. Squeeze a small amount of petroleum oil into the pick-up tube port and on the cylinder
pump housing, See Figure Q.
6. Press the switch of the sprayer for three to five seconds while the sprayer is still turned
upside down. This will force the petroleum oil onto the piston and will protect the
sprayer from drying and the piston from seizing.
