Important Safety Information
Read all safety information before
operating the equipment. Save these
instructions.
Indicates a hazardous situation which,
if not avoided, could result in death or
serious injury.
To reduce the risks of re or explosion,
electrical shock and the injury to
persons, read and understand all
instructions included in this manual. Be
familiar with the controls and proper
usage of the equipment.
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.
WARNING - 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, do not connect the green grounding wire
to either at 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 qualied 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 t the outlet, have
the proper outlet installed by a qualied 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
conguration as the plug. No adapter should be
used with this product.

WARNING - To reduce the risk
of re or explosion:
1. Do not spray ammable or combustible
materials near an open ame, pilot lights
or sources of ignition such as hot objects,
cigarettes, motors, electrical equipment and
electrical appliances. Avoid creating sparks
from connecting and disconnecting power
cords.
2. For use with only water-based or mineral
spirit-type materials with a minimum ash point
of 38ºC (100º F) — Do not spray or clean with
liquids having a ash point of less than 38ºC
(100º F). Flash point is the temperature at which
a uid can produce enough vapor to ignite.
3. Verify that all containers and collection systems
are grounded to prevent static discharge.
4. Connect to a grounded outlet and use
grounded extension cords (electric models
only). Do not use a 3 to 2 adapter.
5. Keep spray area well ventilated. Keep a good
supply of fresh air moving through the area
to keep the air within the spray area free from
accumulation of ammable vapors.
6. Do not smoke in the spray area.
7. Do not operate light switches, engines, or
similar spark producing products in the spray
area.
8. Keep area clean and free of paint or solvent
containers, rags, and other ammable materials.
9. Know the contents of the paint and solvents
being sprayed. Read all Material Safety Data
Sheets (MSDS) and container labels provided
with the paints and solvents. Follow the paint
and solvent manufacture’s safety instructions.
10. Fire extinguisher equipment shall be present
and working.

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 sux 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.
IMPORTANT: Household use only. Intended
for outdoor use ONLY with materials having
ashpoint above 100ºF (38ºC).

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.
Air cap ears

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
STOP
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 rst 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
nish (i. e. runs and sags).
• Always apply a thin coat of material on the rst
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.
6 to 12 inches
Correct
Keep stroke smooth and at an even speed
Even coat throughout
• 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 nish possible.
Incorrect
Do not ex 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 100ºF (38ºC):
 • Alwaysushspraygunoutside.
 • Areamustbefreeofammable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

Maintenance
Cleaning the Filters:
IMPORTANT: You should inspect the air
lters in the turbine to see if it is excessively
dirty. If it is dirty, follow these steps to
replace it.
IMPORTANT: Never operate your unit
without the air lters. Dirt could be sucked in
and interfere with the function of the unit.
1. Unplug the spray gun. Remove the lter cover
from the turbine by removing the two screws
holding it in place.
2. Remove the dirty lters and replace with new
ones. The smooth side of the air lter must be
placed toward the turbine.
3. Secure the cover back onto the turbine.
Cleaning the Air Tube:
Note: If material has entered the air tube, proceed as
follows.
1. Pull the air tube (a) at the top from the nozzle. Screw
o the valve cover (b). Remove the valve seal (c).
Clean all the parts carefully. Make sure to remove any
material from valve seal housing area (d).
IMPORTANT: The air tube and valve seal (c) are only
solvent-resistant to a limited extent. Do not immerse
in solvent, only wipe.
2. Place the valve seal (c) in the valve cover (b) with the
pin facing into the tube.
Note: Installing the valve seal into the valve cover will
be much easier if the valve cover is inverted.
3. Turn the nozzle upside down and screw on the valve
cover (with valve seal inside) from underneath.
Note: Turning the nozzle upside down will prevent
the valve seal from falling out of the valve cover during
reinstallation.
4. Place the air tube on the valve cover and on the nipple
at the nozzle.
