GENERAL SAFETY RULES
WARNING! Read and understand all
instructions. Failure to follow all instructions
listed below may result in electric shock,
fire and / or serious personal injury. The
term “power tool” in all of the warnings
listed below refers to your mains-operated
(corded) power tool.
SAVE THESE INSTRUCTIONS.
1) Work area
a) Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquid, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
c) Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical Safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce the risk of
electric shock.
Grounded tools must be plugged into an
outlet properly installed and grounded in
accordance with all codes and ordinances.
Never remove the grounding prong or
modify the plug in any way. Do not use
any adaptor plugs. Check with a qualied
electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools
should electrically malfunction or break
down, grounding provides a low resistance
path to carry electricity away from the user.
b) Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging the
power tool. Keep the cord away from heat,
oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged or
entangled cords increase the risk of electric
shock.
e) When operating a power tool outdoors,
use an outdoor extension cord suitable
for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric
shock.
Personal Safety
a) Stay alert, watch what you are doing
and use common sense when operating

4
a power tool. Do not use tool while you
are tired or under the influence of drugs,
alcohol, or medication. A moment of
inattention while operating power tools
may result in serious personal injury.
b) Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the
switch is in the off position before plugging
in. Carrying tools with your finger on the
switch or plugging in tools that have the
switch on invites accidents.
e) Do not overreach. Keep a proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewellery or long hair can be
caught in moving parts.
4) Power tool use and care
a) Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job
better and safer at the rate for which it was
designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
c) Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing power
tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
d) Store idle tools out of reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate
the power tool. Power tools are dangerous
in the hands of untrained users.
e)Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
g)Use the tool and accessories, etc., in
accordance with these instructions and
in the manner intended for the particular
type of power tool, taking into account
the working conditions and the work to
be performed. Use of the power tool for
operations different from intended could
result in a hazardous situation.

5
5) Service
Have your power tool serviced by a
qualied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
If the supply cord of this power tool is
damaged it must be replaced by a
specially prepared cord available through
the service organization.
Specic safety rules for HVLP Sprayers
OBSERVE ALL WARNINGS!
This equipment is for professional use only.
WARNING: FIRE AND EXPLOSION HAZARD.
Take all precautions to avoid sources of
sparks and ignition when spraying. Keep
the machine at least 8 meters away from
the spraying operation.
WEAR PROTECTIVE EQUIPMENT AT ALL TIMES.
Always use a respirator, eye protection and
protective clothing and gloves.
EXPLOSION RISK FROM HALOGENATED
HYDROCARBON SOLVENTS
Never use halogenated hydrocarbon
solvents in this machine. Contact with
aluminum parts may cause an explosion.
Some of the most common of these solvents
are: Carbontetrachloride, Chlorobenzene,
Dichloroethane, Dichloroethyl
Ether, Ethylbromide, Ethylchloride, &
Tethrachloethane.
PREVENT STATIC SPARKING FIRE/EXPLOSIONS
Vapors created when spraying can be
ignited by sparks. To reduce the risk of re,
always locate the turbine at least 20 feet (6
m.) away from spray area. Do not plug in
or unplug any electrical cords in the spray
area. Doing so can cause sparks which
can ignite any vapors still in the air. Follow
the coating & solvent manufacturers safety
warnings and precautions.
WARNING: Keep the turbine away from
areas with hazardous concentrations of
ammable vapors. NEVER operate with the
turbine inside a spray booth.
• NEVER point the spray gun at anyone
or any part of the body.
• NEVER put your hand or fingers over
the uid nozzle.
• NEVER try to stop or deect leaks with
your hand, body, or rag.
• NEVER alter equipment in any manner.
• NEVER smoke while in spraying area.
• NEVER spray highly flammable
materials.
• NEVER use around children.
• NEVER allow another person to
use sprayer unless he is thoroughly
instructed on its safe use and given this
operator’s manual to read.
• ALWAYS wear a spray mask/respirator,
gloves and protective eye wear while
spraying.

6
• ALWAYS ensure fire extinguishing
equipment is readily available and
properly maintained.
ALWAYS INSPECT SPRAYING AREA
• Keep the spraying area free from
obstructions.
• Make sure the spraying area has good
ventilation to safely remove vapors
and mists.
• NEVER keep flammable material in
spraying area.
• NEVER spray in vicinity of open ame or
other sources of ignition.
• The spraying area must be at least 20
ft. away from spray unit.
TOXIC FLUID HAZARD
• Hazardous fluid or toxic fumes can
cause serious injury or death if splashed
in eyes or on skin, inhaled or swallowed.
Know the hazards of the fluid you are
using. Store & dispose of hazardous
uid according to manufacturer, local,
state & national guidelines.
• ALWAYS wear protective eyewear,
gloves, clothing and respirator as
recommended by uid manufacturer.
HOSES
Do not allow kinking or crushing of hoses or
allow it to vibrate against rough, sharp or
hot surfaces.
• NEVER use a damaged hose. Before
each use, check entire hose for cuts,
leaks, abrasions, or bulging. If any of
these conditions exist, replace the hose
immediately.
GROUNDING
• Ground the sprayer & other
components in the system to reduce
the risk of static sparking, fire or
explosion which can result in serious
bodily injury and property damage. For
detailed instructions on how to ground,
check your local electrical code.
• ALWAYS ensure switch is in OFF position
before plugging unit in.
Always Ground All of These Components:
1. Turbine: plug the power supply cord,
or extension cord, each equipped
with an undamaged three-prong
plug, into a properly grounded outlet.
DO NOT USE AN ADAPTER. Use only
a 3 wire extension cord that has a
grounding plug, and a receptacle
that will accept the grounding 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. If in doubt, use the

7
next heavier gauge.
2. Hose: use only grounded hoses.
3. Spray gun: grounding is obtained
through connection to a properly
grounded hose and turbine.
WHEN SPRAYING & CLEANING WITH
FLAMMABLE PAINTS AND THINNERS
1. When spraying with ammable liquids,
the unit must be located a minimum
of 6 meters (20 feet) away from the
spraying area in a well ventilated area.
Ventilation must be sufficient enough
to prevent the accumulation of vapors.
2. To eliminate electrostatic discharge,
ground the spray unit & sprayed
object. See GROUNDING. Use only
hoses which are conductive.
3. Do not smoke in spraying/cleaning
area.
• NEVER use cleaning solvents with ash
points below 140 degrees F. Some of
these are: acetone, benzene, ether,
gasoline, naptha. Consult your supplier
to be sure.
FUNCTIONAL DESCRIPTION
This HVLP (High Volume, Low Pressure)
turbine uses a controlled cone of high
volume, low pressure air created by the
gun which can spray with very little waste
and overspray. This high efciency delivery
absolutely minimizes air pollution emissions
associated with paint spraying. Media
which are traditionally sprayed by high
pressure compressor driven paint sprayers
can be sprayed by this new technology.
The paint drying times are even quicker
because the air from the turbine is naturally
warm.
UNPACKING AND ASSEMBLY:
1. Remove all parts from the carton.
2. Check for any damage.
3. Attach the hose to the turbine.
4. Attach the hose to the gun.
PREPARATION
Prepare the paint solution
Strain the paint and all other media
components before you spray
Remember to use a slower drying reducer
than you would normally use with a
conventional air sprayer. The warm air
of the turbine causes faster drying times.
Usually one step slower will do.
For Automotive finishes, reduce and
c a t a l y z e a c c o r d i n g t o t h e p a i n t
manufacturer’s instructions, just remember
to use one step slower reducer.
For Industrial finishes, reduce and catalyze
according to the paint manufacturer’s
instructions. If there are no reduction
instructions, add reducer step by step untill

2. Test the spray pattern and atomization
on a test piece. Hold about 20cm (8
inches) away. Turn the Pattern Adjustor
knob for the desired pattern.
3. Adjust the Speed Control knob on
the turbine to control the air volume.
Generally, it is best to use the minimum
air volume which will achieve
satisfactory atomization. The point is to
get the droplet size as small as possible
while still having the desired coverage.
Too much air will only cause overspray
mist and waste paint. If the Speed
Control knob is at maximum and the
atomization is still not satisfactory, the
atomization can also be controlled by
thinning the paint. One can also use a
different fluid set ( the needle, nozzle
and air cap).
the proper consistency is found. Droplets off
the stir stick should be about one second
apart.
WARNING:
Universal motors, like the one used in this
turbine, by their nature create sparks at the
commutator. Whenever spraying ammable
media, keep the turbine at least 6 meters (20
feet) away from the spraying area.
OPERATION
1. Ensure that all protective clothing and
safety devices are in place and Fill the
paint cup.
2. Allow th e t urbine to wa r m up by
turning it on for a few minutes before
beginning spraying. (This will make
adjusting the gun easier).
3. Adjust the gun on a test surface, then
begin spraying
Adusting the Gun
The gun will normally need to be adjusted
before each use. This is similar to tuning a
musical instrument before playing it.
1. First adjust the Fluid Control Knob. Turn
anti-clockwise for more uid, clockwise
for less fluid. A good starting point
would be about 2-1/2 turns out from
closed.

Choosing Fluid Sets:
The fluid set includes a Needle, a Nozzle
and an Air Cap. These parts are a matched
set. Do not mix parts from other sizes. The
standard fluid set which comes with the
gun is a 1.3mm, which will work well for most
applications.
Different sizes of fluid set will give different
ow rates. A more viscous uid will need a
larger size. A thinner uid will need a smaller
size.
To change to a different uid set:
1. Loosen and remove the Air Cap.
2. Unscrew and remove the Nozzle.
Whenever tightening or loosening
the nozzle, pull the trigger all the way
and hold it to prevent damage to the
seating surfaces of the Needle and
Nozzle.
3. Unscrew the Fluid Control Knob all the
way and remove it, together with the
spring.
4. Pull out the Needle through the back
of the Gun.
5. Replacement is the opposide of
removal.

Spraying Technique:
Keep the gun about 150 to 200mm away
from the surface. Do not swing the arm in
an arc. Rather, keep the gun perpendicular
to the surface and move in a parallel
motion. Make sure the gun is already in
motion before triggering and release
the trigger while the gun is still in motion.
Overlap 50% with each stroke.

10
Clean-up:
Always clean the gun at the end of the day
or between colors
1. U s i n g a r a g m o i s t e n e d w i t h a
compatible solvent, clean the cup and
the outside of the gun.
2. Remove the Air Cap, Bafe and Nozzle
and clean with a cleaning brush. Take
care to avoid damage to the air cap
holes.
3. Remove the needle and clean. Clean
the paint carrying orfices of the gun.
Do not allow solvent to enter the air
carrying orfices of the gun. Therefore
point the gun down while cleaning the
paint orces.
Never soak the entire gun in solvent.
Using Optional Remote Pressure Pots:
The standard set-up of this gun is as an HVLP
turbine cup-feed gun. It is also possible
to use this gun and turbine with a remote
pressure pot (pressure feed set-up). All
that is necessary is to convert the gun. To
convert:
1. Use an appropriate wrench to loosen
the nut to remove the paint cup.
2. Connect the hose from the pressure
pot.
3. Use an appropriate wrench to unscrew
the nipple for the vent tube from the
gun body.
4. Use a bolt with the correct thread to
plug the hole from the nipple.
Pressure relief procedure:
When using a pressure pot, the pot must
always be relieved of pressure before
opening. To relieve pressure:
1. Shut off the air supply to the pot.
2. Open the pressure relief valve on the
pot.
Maintenance:
1. Keep the gun clean
2. Keep the inlet filters of the turbine
clean.
