2. General Safety Instructions
WARNING! Read all safety notications and instructions. Failure to comply with the safety
notications and instructions provided may result in electric shock, re and/or
serious injury. The term "power tool" used below covers both mains-operated
power tools (with mains lead) and accumulator-operated power tools (without
mains lead).
1. Safety at the workplace
a) Keep your workplace clean and well lit. Disorder or unlit workplaces may result in
accidents.
b) Never use the tool in hazardous areas that contain ammable liquids, gases
or dusts. Power tools generate sparks that can ignite the dust or vapors.
c) Keep children and other persons away when using the power tool. You can
lose control of the tool if you are distracted.
2. Electrical Safety
a) The tool plug must t into the socket. The plug may not be modied in any
form. Do not use adaptor plugs together with protective-earthed tools.
Unmodied plugs and suitable sockets reduce the risk of an electric shock.

D
32
W 990 Flexio
GB
32
W 990 Flexio
b) Avoid physical contact with earthed surfaces such as pipes, heating
elements, stoves and refrigerators. The risk through electric shock increases if
your body is earthed.
c) Keep the equipment away from rain and moisture. The risk of an electric shock
increases if water penetrates electrical equipment.
d) Do not misuse the mains lead by carrying the tool by the lead, hanging it
from the lead or by pulling on the lead to remove the plug. Keep the lead
away from heat, oil, sharp edges or moving tool parts. Damaged or twisted
leads increase the risk of an electric shock.
e) If you work outdoors with a power tool, only use extension cables suitable
for outdoor use. The use of an extension lead that is suitable for outdoors reduces
the risk of an electric shock.
f) If you cannot avoid using the tool in a damp environment, use a residual
current operated circuit-breaker. Using a residual current operated circuit-breaker
avoids the risk of electric shock.
3. Safety of Persons
a) Be attentive. Pay attention to what you are doing and work sensibly with
a power tool. Do not use the tool if you are tired or under the inuence of
drugs, alcohol or medication. Just a moment of inattentiveness while using the
tool can lead to serious injuries.
b) Wear personal safety equipment and always wear safety goggles Wearing
personal protective equipment, such as dust mask, non-slip safety shoes, safety helm
or ear protection, depending on the type of power tools, reduces the risk of injury.
c) Avoid accidental starting-up. Make sure that the electric tool is switched o
before you connect it to the power supply, pick it up or carry it. Accidents can
occur if you carry the power tool while your nger is on the switch or if you connect
the power tool to the power supply which it is on.
d) Remove setting tools or wrenches before switching on the power tool. A tool
or wrench that is in a rotating tool part can lead to injuries.
e) Avoid an unnatural posture. Ensure that you are standing securely and
have your balance at all times. This ensures that you can control the tool better in
unexpected situations.
f) Wear suitable clothing. Do not wear wide clothing or jewellery. Keep your
hair, clothes and gloves away from moving parts. Loose clothing, jewellery or
long hair can be caught in moving parts.

g) This device can be used by children over the age of 8 as well as by people
with restricted physical, sensory or mental abilities or who have little
experience or knowledge about it, providing they are supervised or
instructed on how to use the device safely and what risks are involved.
Children may not play with the device. User maintenance and cleaning may not be
carried out by children unattended.
4. Usage and treatment of the electric tool
a) Do not overload the tool. Use the power tool designed for the work that you
are doing. You work better and safer in the specied performance range if you use
the suitable power tool.
b) Do not use power tools whose switch is defective. A power tool that cannot be
switched on or o is dangerous and has to be repaired.
c) Remove the plug from the socket before carrying out tool settings, changing
accessories or putting the tool away. This precautionary measure prevents
unintentional starting of the tool.
d) Store unused power tools so that they are inaccessible to children. Do not
let persons use the tool who are not familiar with it or who have not read
these instructions. Power tools are dangerous when they are used by inexperienced
persons.
e) Take proper care of your tools. Check whether the moving parts function
trouble-free and do not jam, whether parts are broken or damaged so that
the tool function is impaired. Have damaged parts repaired before using
the tool. Many accidents have their origin in power tools that have been maintained
badly.
f) Use the power tool, accessories, insert tools, etc. in accordance with these
instructions and in a fashion specied for this special tool type. Take the
working conditions and the activity to be carried out into consideration. The
use of power tools for purposes other than the intended ones can lead to dangerous
situations.
5. Service
a) Have your tool repaired only by qualied specialist personnel and only with
original spare parts. This ensures that the tool safety is maintained.
b) If the supply cord is damaged, it must be replaced by the manufacturer or it’s
service agent or a similarly qualied person in order to avoid a safety hazard.

5. Field of application
Many dierent coating substances can be processed with the W 990.
A dierent spray attachment must be used, depending on the coating substance:
Coating Materials Application tools
Water-soluble interior wall paint
(dispersions and latex paint) DirectFeed spray attachment
Water- and solvent-based paints, nishes,
primers, 2-component paints, clear
nishes, automotive nishes, staining
sealers and wood sealer-preservatives.
All coating materials with the red Perfect
Spray logo
Standard spray attachment
6. Coating Materials Suitable for Use
Water-soluble interior wall paint (dispersions and latex paint)
Water-based paints, nishes, primers, clear nishes, automotive nishes, staining sealers
and wood sealer-preservatives.
Attention! Never suck solvent-based materials directly via the suction system.
Pumps and hoses are not solvent resistant and could be damaged.
7. Coating Materials Not Suitable for Use
Materials that contain highly abrasive components, facade paint, caustic solutions and
acidic coating substances. Flammable materials.
The following materials can only be processed with optional
accessories
Fine plaster (maximum grain size 1 mm,Wall Extra Texture spray attachment, order no.
2362225 (UK)/ 2361755 (AUS))
Solvent-based wall paints (Wall Extra I-Spray spray attachment, order no. 2361746)
8. Preparation of the workplace
Sockets and plugs must be masked. Risk of an electric shock as a
consequence of sprayed material entering the socket!
Mask all the areas and objects that are not to be spray painted, or
remove them from the work area. No liability is assumed for damage
due to overspray. Silicate paint corrodes glass and ceramic surfaces
upon contact! All such surfaces must therefore be completely covered.

iPay attention to the quality of the adhesive tape used.Do not use excessively
strong adhesive tape on wallpaper and painted surfaces, in order to avoid
damaging these surfaces when removing the tape. Remove adhesive tape
slowly and evenly; do not use jerky movements. Do not leave adhesive tape
on surfaces any longer than necessary, in order to minimise the possibility
of residues when removing. Also observe the adhesive tape manufacturer's
instructions.
9. Preparation of the Coating Material
Mix the material well in the original container. When using interior wall paint, an agitator
is recommended.
i
W 990 has been developed for use with all conventional paints in their
undiluted form. If the surface is smooth and the paint you are using is very thick
and gel-like, dilute it by 10%. Dilution can be necessary if the atomisation is
coarse or if the ow rate is too low even at the maximum setting.
Detailed information about the various materials and the maximum permitted
dilution can be found on the manufacturers' technical data sheets (e.g. available
on the Internet). Our online database Wagner Spray Guide has tips on using
many materials tested by our experts: www.sprayguide.wagner-group.com
iSpray material that is at least at room temperature provides a better spray
result.
10. Start-up
•
Put the machine down only on a level, clean
surface.
•
Before connecting to the mains supply, be
sure that the supply voltage is identical with
the value given on the rating plate.
•
Take the suction hose (g. 2, 1) out of the
holder.
•
Pull the yellow handle (g. 2, 2) away from the
device and unhook it.

•
Push the handle into the device
compartment. (Fig. 3)
•
Fold up the black bracket (g. 4, 4) and
remove from the spray gun from the device.
•
Completely unwind the material hose.
iThe following steps are only
necessary if you want to convey
the material directly out of the
paint bucket. If you want to use the
Standard spray attachment, please
continue reading chapter 11.
•
Hold the height-adjustable attachment for
paint bucket (g. 5, 5) at the side and pull
upwards.
•
Position the paint bucket on the ledge (g. 6,
6) so that the bucket handle is between both
xtures.

•
Push the height-adjustable paint bucket
attachment (g. 7, 5) down in order to secure
the bucket.
iImportant: Only operate device
when lter disk is inserted (Fig. 5,
A). Otherwise the suction lter can
suction to the bottom of the paint
container during operation.
•
Secure the suction hose (g. 8, 1) inside the
xture and push to the oor of the bucket.
iMake sure that there is always
enough paint in the container. If the
pump sucks air, the paint might eject
from the gun intermittently and
create stains on the wall.
Tip: If the paint bucket is at an
angle the contents will be able to
be suctioned o entirely. Therefore
place a small object underneath the
paint bucket.
•
Plug in the power cable.
•
Switch the device on (position I) at the main
switch (g. 9, 7).
•
Aim the spray gun at a piece of cardboard
and depress the trigger until the air has been
pumped out of the material hose and an
even spray of the material is produced (this
can take up to 1 minute, depending on the
paint).
iIf the material does not feed into
the hose or only in intervals, the
material is too thick and blocks
the hose. See chapter 22 to get the
device back into operation.

11. Use the Standard spray
attachment and other
spray attachments
(accessories)
i
You only need the turbine unit
to operate the Standard spray
attachment.
Do not set aside the spray
attachment if it is lled with
paint.
•
Separate the DirectFeed spray attachment
(g. 10, 1) from the turbine unit (2).
•
Disconnect the power plug on the turbine
unit from the material hose.
•
Disconnect the turbine unit power plug from
the material hose.
•
Connect the Standard spray attachment (g.
10, 3) to the turbine unit (2).
•
Insert the turbine unit power plug into the
socket.
i
Always plug the turbine unit into a
separate socket if you are working
with the Standard attachment. If
the turbine unit is connected to
the material hose, the pump will
run unnecessarily which leads to
increase wear and tear and energy
consumption.
iFurther information about the spray
attachment can be found in the
provided Operating Manual of the
Standard spray attachment. Please
also read the information about
regulating the air ow and spraying
techniques in chapters 14 and 17.

13. Adjusting the Material
Volume
iThe material quantity is set
depending on the characteristics
of the material (viscosity) and the
working speed of the operator.
This setting is performed by adjusting
the material ow limiter (g. 14, 1) from 1
(minimum) to 12 (maximum).
iWe recommend starting with a
low material ow setting and then
gradually adjusting this to suit needs.
14. Setting the Amount of Air
i
Depending on the viscosity of the
material to be sprayed and the
nish of the object to be coated,
it may be advisable to vary the
amount of air. Very low viscosity
materials, such as watery glazes
do not have to be atomised with
the maximum amount of air. In this
case it is advisable to reduce the
amount of air and thus minimize
the spray vapour.
This also applies for the use of the
Detail and Corner/Reach spray
attachment (accessory).
Turn the air quantity regulator (g. 15, 1) until
the level you want is above the arrow.

17. Spray Technique
i
The spray result depends heavily on the smoothness and cleanliness of the
surface to be sprayed. Therefore the surface should be carefully prepared and
kept free of dust.
iThe enclosed practice poster is ideal for familiarising yourself with operation
of the spray gun. After trying out the rst spray coatings, it makes sense to
test it further on cardboard or a similar surface in order to nd out the right
ow rate of paint and air for the best spray pattern.
•
Cover all surfaces not to be sprayed.
iImportant: Start at the edge of the area to be sprayed. Start the spray
movement rst of all, and then press the trigger. Avoid interruptions
within the area to be sprayed.
•
The spray movement should come from the
arm, not just from the wrist. This ensures that
a uniform distance is maintained between the
spray gun and the spray surface during the
spray operation. Select a distance of 10 - 30
cm, depending on the desired spray jet width.
Fig. 19 A:
CORRECT Even distance to the
object.
Fig. 19 B:
INCORRECT An uneven distance
will result in uneven paint
application.
•
Move the spray gun evenly cross-wise or up-
and-down, depending on the spray pattern
setting.
•
An even movement of the spray gun results in
an even surface quality.
iImportant: Wipe o the nozzle and air cap
regularly to make sure they do not get
blocked.

i"Cross spray" when using paint
with a poor covering capacity or if
the surface is highly absorbent (Fig.
20).
•
Interior wall paint in strong colour shades
should be applied at least twice (allow rst
paint coat to dry rst). This will ensure good
coverage.
18. Interruption of Work
•
Turn the machine o (position 0).
•
Depress the trigger to release pressure from
the system.
•
Leave the suction hose in the paint.
•
Wet paint surface in paint container with a
little water to prevent a skin from forming.
19. Transportation (g. 21)
Important. The bucket handle
must be between both xtures.
Otherwise the bucket could be
tipped by the weight of the W 990
when being transported and leak
paint.
Attention! Do not pour any
liquids over the basic unit.
•
Once the device is attached to the paint bucket,
you can carry it easily together with the bucket.
Check that the device is securely attached to
the bucket before it is lifted by the handle.
•
Do not carry or pull the device by the hoses
to avoid any damage.
