1 SAFETY REGULATIONS FOR
AIRLESS SPRAYING
All local safety regulations in force must be observed.
The following sources are just a sample of those containing
safety requirements for Airless spraying.
a) The European Standard„Spray equipment for coating ma-
terials – safety regulations„ (EN 1953).
The following safety regulations are to be observed in order
to ensure safe handling of the Airless high-pressure spraying
unit.
1.1 FLASH POINT
Only spray coating materials with a ash point
of 21 °C or higher.
The ash point is the lowest temperature at
which vapors develop from the coating ma-
terial. These vapors are sucient to form an
inammable mixture over the air above the
coating material.
1.2 EXPLOSION PROTECTION
Do not use the unit in work places which are
covered by the explosion protection regula-
tions. The unit is not designed to be explo-
sion protected. Do not operate the device in
explosive areas (zone 0, 1 and 2). Explosive ar-
eas are, for example, places where paints are
stored and locations in direct proximity to the
object being sprayed. Keep the device at least
3 m from the object you are spraying.
1.3 DANGER OF EXPLOSION AND FIRE FROM
SOURCES OF IGNITION DURING SPRAYING
WORK
There must be no sources of ignition such as,
for example, open res, lit cigarettes, cigars or
tobacco pipes, sparks, glowing wires, hot sur-
faces, etc. in the vicinity.
1.4 DANGER OF INJURY FROM THE SPRAY JET
Attention, danger of injury by injection!
Never point the spray gun at yourself, other
persons or animals.
Never use the spray gun without spray jet
safety guard.
The spray jet must not come into contact
with any part of the body.
In working with Airless spray guns, the high
spray pressures arising can cause very dan-
gerous injuries. If contact is made with the
spray jet, coating material can be injected
into the skin. Do not treat a spray injury as a
harmless cut. In case of injury to the skin by
coating material or solvents, consult a doctor
for quick and correct treatment. Inform the
doctor about the coating material or solvent
used.
1.5 SECURE SPRAY GUN AGAINST UNINTENDED
OPERATION
Always secure the spray gun when mounting or dismounting
the tip and in case of interruption to work.
1.6 RECOIL OF SPRAY GUN
When using a high operating pressure, pull-
ing the trigger guard can eect a recoil force
up to 15 N.
If you are not prepared for this, your hand can
be thrust backwards or your balance lost. This
can lead to injury.
1.7 BREATHING EQUIPMENT AS PROTECTION
AGAINST SOLVENT VAPORS
Wear breathing equipment during spraying work.
A breathing mask is to be made available to the user.
SAFETY REGULATIONS
1.8 PREVENTION OF OCCUPATIONAL ILLNESSES
Protective clothing, gloves and possibly skin protection cream
are necessary for the protection of the skin.
Observe the regulations of the manufacturer concerning coat-
ing materials, solvents and cleaning agents in preparation,
processing and cleaning units.

SAFETY REGULATIONS
1.9 MAX. OPERATING PRESSURE
The permissible operating pressure for the spray gun, spray
gun accessories, unit accessories and high-pressure hose
must not fall short of the maximum operating pressure of 25
MPa (250 bar or 3625 psi).
1.10 HIGHPRESSURE HOSE
Attention, danger of injury by injection! Wear
and tear and kinks as well as usage that is not
appropriate to the purpose of the device can
cause leakages to form in the high-pressure
hose. Liquid can be injected into the skin
through a leakage.
High-pressure hoses must be checked thoroughly before
they are used.
Replace any damaged high-pressure hose immediately.
Never repair defective high-pressure hoses yourself!
Avoid sharp bends and folds: the smallest bending radius
is about 20 cm.
Do not drive over the high-pressure hose. Protect against
sharp objects and edges.
Never pull on the high-pressure hose to move the device.
Do not twist the high-pressure hose.
Do not put the high-pressure hose into solvents. Use only
a wet cloth to wipe down the outside of the hose.
Lay the high-pressure hose in such a way as to ensure that
it cannot be tripped over.
Only use WAGNER original-high-pressure
hoses in order to ensure functionality, safety
and durability.
1.11 ELECTROSTATIC CHARGING FORMATION OF
SPARKS OR FLAMES
Electrostatic charging of the unit may occur
during spraying due to the ow speed of
the coating material. These can cause sparks
and ames upon discharge. The unit must
therefore always be earthed via the electrical
system. The unit must be connected to an
appropriately-grounded safety outlet.
An electrostatic charging of spray guns and the high-pressure
hose is discharged through the high-pressure hose. For this
reason the electric resistance between the connections of the
high-pressure hose must be equal to or lower than 1 MΩ.
1.12 USE OF UNITS ON BUILDING SITES AND
WORKSHOPS
The unit may only be connected to the mains network via a
special feeding point with a residual-current device with INF
≤ 30 mA.
1.13 VENTILATION WHEN SPRAYING IN ROOMS
Adequate ventilation to ensure removal of the solvent vapors
has to be ensured.
1.14 SUCTION INSTALLATIONS
The are to be provided by the unit user in accordance with the
corresponding local regulations.
1.15 EARTHING OF THE OBJECT
The object to be coated must be earthed.
(Building walls are usually earthed naturally)
1.16 CLEANING THE UNIT WITH SOLVENTS
When cleaning the unit with solvents, the
solvent should never be sprayed or pumped
back into a container with a small opening
(bunghole). An explosive gas/air mixture can
arise. The container must be earthed.
1.17 CLEANING THE UNIT
Danger of short-circuits caused by water in-
gression!
Never spray down the unit with high-pres-
sure or high-pressure steam cleaners.
1.18 WORK OR REPAIRS AT THE ELECTRICAL
EQUIPMENT
These may only be carried out by a skilled electrician. No li-
ability is assumed for incorrect installation.
1.19 WORK AT ELECTRICAL COMPONENTS
Unplug the power plug from the outlet before carrying out
any repair work.

SAFETY REGULATIONS/ GENERAL VIEW OF APPLICATION
2 GENERAL VIEW OF APPLICATION
2.1 APPLICATION
SF 23 Pro is an electric driven unit for the airless atomization of
dierent painting materials. Also it is able to feed the internal
feeded paint roller, which is available as accessory.
SF 23 Pro is made for jobs in the workshop and on the build-
ing site.
The SF 23 Pro’s device output is designed so that dispersions
can be processed indoors and outdoors for small to medium-
sized objects.
When painting, the device is suitable for all kinds of typical
painting jobs, e.g.:
doors, door frames, balustrades, furniture, woodencladding,
fences, radiators (heating) and steel parts.
We recommend using the top container for paintwork.
2.2 COATING MATERIAL
Diluting lacquers and paints or those containing solvents, two-
component coating materials, dispersion and latex paints.
No other materials should be used for spraying without WAG-
NER‘s approval.
Pay attention to the Airless quality of the
coating materials to be processed.
The unit is able to process coating materials with up to
20,000 mPas. If highly viscous coating materials cannot be tak-
en in or the performance of the unit is to low, the paint must
be diluted in accordance with the manufacturer‘s instructions.
Attention: Make sure, when stirring up with
motor-driven agitators that no air bubbles
are stirred in. Air bubbles disturb when spray-
ing and can, in fact, lead to interruption of
operation.
2.2.1 COATING MATERIALS WITH SHARPEDGED
ADDITIONAL MATERIALS
These particles have a strong wear and tear eect on valves
and tips, but also on the heating hose and spray gun. This im-
pairs the durability of these wearing parts considerably.
1.20 SETUP ON AN UNEVEN SURFACE
The front end must always point downwards in order to avoid
sliding away.
If possible do not use the unit on an inclined surface since the
unit tends to wander through the resulting vibrations.

Super Finish 23 Pro
GB
GENERAL VIEW OF APPLICATION
2.2.2 FILTERING
Sucient ltering is required for fault-free operation. To this
purpose the unit is equipped with a suction lter (Item 1) and
an insertion lter in the spray gun (Item 2). Regular inspec-
tion of these lters for damage or soiling is urgently recom-
mended.
A high-pressure lter (Item 3) -available as accessory- is rising
up the ltering surface and will make the work more comfort-
able.
3. DESCRIPTION OF UNIT
3.1 AIRLESS PROCESS
The main area of application are thick layers of highly viscous
coating material.
At the SF 23 Pro unit a diaphragm pump takes in the coating
materials and transports it via a high-pressure hose to the
spray gun with the airless tip. Here the coating material at-
omizes since it is pressed through the tip core at a maximum
pressure of 25 MPa (250 bar, 3625 psi). This high pressure has
the eect of micro ne atomisation of the coating material.
As no air is used in this process, it is described as an AIRLESS
process.
This method of spraying has the advantages of nest atomisa-
tion, cloudless operation (depending of a correct unit adjust-
ment) and a smooth, bubblefree surface. As well as these, the
advantages of the speed of work and convenience must be
mentioned.
3.2 FUNCTIONING OF THE UNIT
The following section contains a brief description of the tech-
nical construction for better understanding of the function:
SF 23 Pro is an electrically driven high-pressure paint spraying
equipment.
The electric motor (1) drives the hydraulic pump via planetary
gears (2). A piston (3) is moved up and down so that hydraulic
oil is moved under the diaphragm (4) which then moves.
In detail:
The downwards movement of the machine opens the disk in-
let valve (5) automatically and coating material is sucked in.
During the upwards movement of the diaphragm, the coating
material is displaced and the outlet valve opens while the inlet
valve is closed.
The coating material ows under high pressure through the
high-pressure hose to the spray gun and is atomized when it
exists from the tip.
The pressure control valve limits the set pressure in the hy-
draulic oil circuit and thus also the pressure of the coating
material.
A pressure change when the same tip is used also leads to a
change in the amount of paint atomized.

SPRAYING TECHNIQUE / HANDLING THE HIGHPRESSURE HOSE / INTERRUPTION OF WORK
5 SPRAYING TECHNIQUE
•
The key to a high-quality result is the even coating of the
entire surface. Move your arm at a uniform speed and hold
the spray gun at a constant distance from the surface. The
ideal distance is around 30 cm between the spray nozzle and
the surface. (Fig. A)
•
Hold the spray gun parallel to the surface. Move the gun using
your entire arm, not just the wrist. (Fig. B)
•
Hold the spray gun at right angles to the surface. Otherwise the
coating will be thicker at one end than the other. (Fig. C)
•
Pull the trigger guard once you have started the movement.
Release the trigger again before you nish the movement.
(Fig. D) Avoid interruptions within the spray surface.
•
Allow each stripe to overlap by around 30%. This will ensure
even coating. (Fig. E)
•
Use the lowest possible pressure setting to create the desired
spray pattern in order to minimise spray mist.
•
To achieve perfect surfaces at varnishing works, special
accessories are available at Wagner, e.g. FineFinish tips. Your
Wagner dealer will advise you.

SPRAYING TECHNIQUE / HANDLING THE HIGHPRESSURE HOSE / INTERRUPTION OF WORK
6 HANDLING THE HIGHPRESSURE
HOSE
The unit is equipped with a high-pressure hose specially suit-
ed for diaphragm pumps.
Danger of injury through leaking high-
pressure hose. Replace any damaged high-
pressure hose immediately.
Never repair defective high-pressure hoses
yourself!
The high-pressure hose is to be handled with care. Avoid sharp
bends and folds: the smallest bending radius is about 20 cm.
Do not drive over the high-pressure hose. Protect against
sharp objects and edges.
Never pull on the high-pressure hose to move the device.
Make sure that the high-pressure hose cannot twist. This can
be avoided by using a Wagner spray gun with a swivel joint
and a hose system.
When using the high-pressure hose while
working on scaolding, it is best to always
guide the hose along the outside of the scaf-
folding.
The risk of damage rises with the age of the
high-pressure hose.
Wagner recommends replacing high-pres-
sure hoses after 6 years.
Only use WAGNER original-high-pressure
hoses with internal heating in order to ensure
functionality, safety and durability.
7 INTERRUPTION OF WORK
1. Set pressure relief valve to (pressure relief, circulation).
2. Switch the unit o using the ON/OFF switch (Pos. 0).
3. Pull trigger of the spray gun to decrease the pressure of
the high pressure hose and the spray gun.
3. Secure the spray gun, refer to the operating manual of the
spray gun.
4. Remove tip from tip holder and store the tip in a small ves-
sel with suitable cleaning agent.
5. Leave the suction system immersed in the coating mate-
rial or immerse it in the corresponding cleaning agent.
The suction lter and unit should not dry out.
6. Cover the material container in order to prevent the paint
from drying.
In using quick-drying or two-component
coating materials, do not fail to rinse unit
through with a suitable cleaning agent dur-
ing the processing period.

DISPLAYS AT THE UNIT / CLEANING THE UNIT
8 CLEANING THE UNIT
A clean state is the best method of ensuring operation with-
out problems. After you have nished spraying, clean the unit.
Under no circumstances may coating material rests dry and
harden in the unit. The cleaning agent used for cleaning (only
with a ash point above 21 °C) must be suitable for the coat-
ing material used.
Warm water improves the cleaning eect in
the case of water-dilutable coating materials.
• Secure the spray gun, refer to the operating manual of
the spray gun.
Remove and clean the tip and tip holder.
• Unit with suction system
1. Set pressure relief valve to (circulation).
2. Switch the device on (Pos. I) using the ON/OFF switch.
3. Remove the suction system from the material container.
The return pipe hose remains over the material container
until barely any coating material comes out.
4. Immerse the suction system into a container lled with a
suitable cleaning agent
5. Turn the pressure control valve back in order to set a mini-
mal spraying pressure.
6. Set pressure relief valve to (spray).
7. Pull the trigger of the spray gun in order to pump the
remaining coating material from the suction hose, high-
pressure hose and the spray gun into an open container (if
appropriate, increase the pressure at the pressure control
valve slowly in order to obtain a higher material ow).
The container must be earthed in case of
coating materials which contain solvents (e.g.
by using a metal container).
Caution! Do not pump or spray in container
with small opening (bunghole)!
See safety regulations.
8. Set pressure relief valve to (circulation).

CLEANING THE UNIT
8.1 CLEANING THE UNIT FROM THE OUTSIDE
First unplug the power plug from the outlet.
Danger of short-circuits caused by water
ingression! Never spray down the unit with
high-pressure or high-pressure steam clean-
ers.
Do not put the high-pressure hose into sol-
vents. Use only a wet cloth to wipe down the
outside of the hose.
Wipe down unit externally with a cloth which has been im-
mersed in a suitable cleaning agent.
8.2 SUCTION FILTER
Clean lters always ensure maximum volume,
constant spray pressure and problem-free
functioning of the unit.
Unit with suction system
1. Unscrew the lter (Item 1) from the suction tube.
2. Clean or replace the lter.
Carry out cleaning with a hard brush and a corresponding
cleaning agent.
8.3 HIGHPRESSURE FILTER
1. Set pressure relief valve to (pressure relief, circulation).
2. Switch the unit o using the ON/OFF switch (Pos. 0).
3. Open the high-pressure lter and clean the lter insert. To

CLEANING THE UNIT / SERVICING
9.1 GENERAL SERVICING
We strongly recommend having an annual
check carried out by technicians for safety
reasons. Please observe all the applicable na-
tional regulations.
Minimum check before every startup:
1. Check the high-pressure hose, spray gun with rotary joint,
power supply cable with plug for damage.
2. Check whether the pressure gauge can be read.
Check at periodical intervals:
1. Check inlet and outlet valve according wear. Clean it and
replace worn out parts.
2. Check all lter inserts (spray gun, suction system) clean it
and replace if necessary.
9 SERVICING
9.2 HIGHPRESSURE HOSE
Inspect the high-pressure hose visually for any notches or
bulges, in particular at the transition in the ttings. It must be
possible to turn the union nuts freely. A conductivity of less
than
1 MΩ must exist across the entire length.
Have all the electric tests carried by the Wag-
ner Service.
The risk of damage rises with the age of the
high-pressure hose.
Wagner recommends replacing high-pres-
sure hoses after 6 years.
8.4 CLEANING THE AIRLESS SPRAY GUN
1. Rinse the Airless spray gun with a suitable cleaning agent
under lower operating pressure.
2. Clean the tip thoroughly with a suitable cleaning agent so
that no suitable coating material rests remain.
3. Do not store the tip in solvent because this reduces the
durability considerably.
4. Clean the outside of the Airless spray gun thoroughly.
1. Unclip the top of the trigger guard (1) from the gun head.
2. Using the bottom of the trigger guard as a wrench, loosen
and remove the handle assembly (2) from the gun head.
3. Pull the old lter (3) out of the gun head. Clean or replace.
4. Slide the new lter, tapered end rst, into the gun head.
5. Thread the handle assembly into the gun head. Tighten
with the trigger wrench.
6. Snap the trigger guard back onto the gun head.

sign.
6. Remount the covers carefully (do not squeeze any cables!)
10.5 TYPICAL WEAR PARTS
Despite the use of high-quality materials the highly abrasive
eect of the paints means that wear can occur at the follow-
ing parts:
Inlet valve
For replacing refer to Section 10.1
(failure becomes noticeable through performance loss and/or
poor or no suction)
Outlet valve
For replacing refer to Section 10.2
(failure becomes noticeable through performance loss and/
or poor suction) The outlet valve is usually considerably more
durable than the inlet valve. Thorough cleaning may already
help here.
