Wagner Product Training
Safety Considerations and
Recommendations
As with any power tool, you need to exercise a level of care to ensure user
safety.
Wagner products used correctly are very safe, and meet all of the necessary
safety requirements.
There has not been a reported case of skin injection injury in over 10 years,
but safety should always be high priority
2
Safety Considerations and
Recommendations – cont.
1. Before using the equipment, read and observe the safety instructions detailed
in the Users Manual.
2. Make sure the electrical lead is in good working condition.
3. Spray materials emerge from the nozzle tip under high pressure. Never point
the spray stream towards human beings or animals. In the event of injury to
the skin by paint or solvents, quick expert treatment by a physician is
essential. The physician should be informed of the type of paint or solvent
involved.
4. To avoid the hazard of explosion when spraying, provide for effective natural
or artificial ventilation.
3
Safety Considerations and
Recommendations – cont.
5. No sources of ignition are to be in the immediate area when spraying eg.
open flame, cigarettes, sparks, glowing wires and hot surfaces.
6. The spray gun is not a toy. Keep out of reach of children.
7. Before carrying out any type of work on the spray gun, unplug the lead from
the power socket.
8. Do not use spray guns to spray flammable liquids.
9. Do not spray any liquid of unknown hazard potential.
10. Wear a breathing mask or ear protection as required.

Air Spray
Process
Paint is drawn into the gun by venturi
and is a atomized by injected air. The
fan can be manipulated by air
introduced around the fan. Because
the paint is both picked up and
atomized by air the paint leaves the
nozzle in form of a fine mist. The paint
droplets are suspended in the air and
tend to float, causing overspray. The
transfer efficiency is very low, only 2545% of the coating reaches the job
Advantages
• Adjustable air control
• Adjustable fluid control
• Fan width adjustment
Disadvantages
• Poor transfer efficiency
• Overspray

Airless Spray
Process
Paint is drawn into the gun by
vacuum and is pressurised. It is
forced trough a small orifice causing
it to atomise. The paint is delivered
to the job by pressure only, therefore
there is little overspray although you
do get fallout. Due to fixed tips a
percentage of the paint can be
sprayed past the job. The transfer
efficiency of an airless gun is 6580%
Advantages
• Fast coating time
• Good transfer efficiency
• Low overspray
Disadvantages
• Fixed tips
• Not adjustable

Functional Principle of Electric Hand
Spray Guns
The heart of the airless unit is the
piston which causes atomisation
by high pressure.
The oscillator pushes the piston
forwards. As soon as the piston
spring moves the piston backwards,
a vacuum is set up in the pump
cylinder and this sucks in the
spraying material. In the next
forward movement of the piston, the
suction aperture is closed and the
spray material is pressed outwards
under high pressure through the
valve system – with no air.
The spray flow rate and the
spraying pressure can be
smoothly adjusted with the
regulating screw

Power Painter Introduction
Power Painters let you paint quickly and smoothly. The drawing below shows
the set of typical components. Refer to the selection chart for model specific
components.
Optional accessories may include a backpack container, additional spray tips, or
a packet of Cleaner/Lubrication depending on model.
10
How it works
• Power Painters
utilise an airless piston pump in the head of the unit to spray paint. Airless
refers to a method of spraying paint utilising high pressure to atomise paint by
forcing it through a small tip (orifice) opening.
• Container
holds the material to be sprayed. 600ml and 800ml containers are available
depending on the model.
• Suction Set
channels the paint to the pump from the integral container. Paint can also be
drawn from a paint can when using the suction extension supplied with each
model.
• Valves
During the backward stroke of the piston a vacuum is created in the
pump by the seal from the swirl valve to the housing. On the forward stroke
the piston forces paint past the sealing block, swirled through the head and
finally atomised within the spray tip to spray paint.
11
Definitions
• Speed
some models have more than one speed which allows the user to adjust the
width of the spray.
• Tip (Orifice)
size depends on the material being applied. The shape of the tip determines
the shape of the spray pattern. Standard pattern is round unless equipped
with the optional “Wide Angle” tip.
• Atomisation
the process in which the paint is broken up into microscopic droplets.
• Pump
a mechanical device that moves fluid by pressure or suction.
• Pressure (PSI)
Pounds per square inch
• Viscosity
resistance of a liquid to sheer forces and hence to flow.

When to use Power Sprayers
Power Sprayers are classified as painting tools. They are designed to cut
labor time, minimise waste, and improve the surface quality.
Power Sprayer Applications include:
• Roofing
• Timber Fence
• Casual Doors
• Pergola / Gazebo
• Lattice
• Boat Anti Fouling
• Broad Walls
• Sheds

Getting started
Prepare the spraying surface area and surrounding areas. The spray result
depends heavily on the smoothness and cleanliness of the surface to be sprayed.
The surface should be carefully prepared and kept free of dust. Ensure that you
cover all areas that are not to be sprayed. Keep in mind that when working with
wind, paint mist can be transported over great distances.
Remove the Paint Power Sprayer from the box. Check to ensure that all parts and
accessories have been provided (refer to users manual for more information). If
the gun has been used previously, make sure all parts are clean and assembled
correctly.

Prepare the spray material
Paints are usually sold in a spreadable, undiluted state.
the recommended run-out time, additional thinning of
the spray material will be required.
The paint usually needs to be diluted for use with the
spray gun. To thin the material you are using, try Paint
Easy™ Paint Conditioner for water based paints. It
thins the paint by adding a specially formulated
material for a finer spray. Water will also work but it will
dilute the material. For oil-based materials, use the
thinning agent recommended on the material container.
To achieve the correct dilution you have to use the
viscosity test cup supplied with the unit (viscosity =
consistency of the paint). Dip the viscosity test cup
completely into the spray material Hold the test cup up
and measure the time (in seconds) until the liquid
completely empties out. Compare the measured “runout” time with the viscosity table detailed on the
following slide. If the actual run-out time is greater than
