Technical Data
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted sound pressure level of the product
is 74 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).
Wear hearing protection!
Vibration total values ah(triax vector sum) and uncertainty K
determined according to EN 60745:
ah< 2.5 m/s2, K= 1.5 m/s2.
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications,withdifferentaccessories orpoorlymaintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of thelevel of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
fromthe effectsofvibrationsuch as:maintain the tooland the
accessories, keep hands warm, organise work patterns.

Operation
fBefore any work on the machine itself, pull the mains
plug.
Preparing for Operation
When purchasing paint, observe its environmental compati-
bility.
Preparing the Spray Surface
The spray surface must be clean, dry and grease-free.
When spraying, all non-covered surfaces can be soiled by the
spray mist. Therefore, thoroughly prepare the area around
the surface to be sprayed:
– Cover or mask off floors, furnishings, doors, windows as
well as door and window frames, etc.
Preparing the Paint
– Prepare the paint according to the manufacturer’s instruc-
tions.
In case the paint manufacturer does not provide informa-
tion on diluting the paint, we recommend a 10 % dilution
with water.
– Stir the paint thoroughly.
– Fill a sufficient amount of paint into the container 10 using
the filling funnel 28.
– Thoroughly stir the diluted paint in the container once
more.
– Firmly screw the container 10 to the spray gun.
– Carry out a test-spray run on a test surface. (see “Spray-
ing”, page 16)
When the spraying pattern is perfect, start the spray job.
or
When the spraying result is not satisfactory or when no paint
comesout, pleasecontinue asdescribedunder “Correction of
Malfunctions” on page 18.
Adjusting the Suction Tube (see figure B)
– Unscrew the container 10 from the spray gun.
– Turn the suction tube 12 so that the spray material can be
sprayed with almost no residue:
Starting Operation
fObserve correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
fDuring operation, the base unit must always stand hor-
izontally on a level surface. Never tilt the base unit or
set it upright when switched on.
fPay attention that the base unit cannot draw in dust or
other contamination during operation.
fMake sure never to spray on the base unit.
Switching On
– Always place the base unit horizontally on a level and clean
surface.
– Plug the mains plug into a socket outlet.
– Grasp the spray gun by the handle and point it at the spray
surface.
– For switching on, turn the control knob 24 on thebase unit
toward the right to the stop.
Itis recommendedto startwiththemaximum airflow. (see
“Adjusting the Air Flow”, page 17)
– Pull the trigger switch 9on the spray gun.
Note: When the base unit is switched on, air always flows out
at the nozzle .
Switching Off
– Release the trigger switch 9and turn the control knob 24
toward the left to the stop.
– Place down the spray gun in the set-down port 25.
– Pull the mains plug from the socket outlet.
Working Advice
Spraying (see figures C–D)
– Firstly, carry out a test-spray run and adjust the spray pat-
tern and the spray material quantityaccording to the spray
material. (For adjustments, see the following sections)
– Make sure to hold the spray gun with a uniform clearance
of 25 cm vertical to the object being sprayed.
– Move the spray gun evenly cross-wise or up-and-down, de-
pending on the spray pattern setting.
Aneven surface quality isachievedwhen the paths overlap
by4–5cm.
– Avoid interruptions within the spray surface.
Guiding the spray gun evenly will provide uniform surface
quality.
Non-uniform clearance and spray angle lead to heavy forma-
tion of paint mist and thus to an uneven surface.
Never spray the container completely empty. When the suc-
tion tube no longer immerses in the spray material, the spray
jet will break off, resulting in a non-uniform surface.
Whenspraymaterialdepositsonthenozzleneedle16andthe
air cap 3, clean both components with water.
