Suitable spray materials and recommended diluting
agents
f
When diluting, pay attention that the spray material
and the diluting agent correspond. When using a faulty
diluting agent, lumps can develop that can lead to clogging
of the spray gun.
The tool is not suitable for processing dispersion paint (wall
paint/latex).
Please also observe the practical advice/tips of the spray ma-
terial manufacturers.
Diluting Spray Material
For spray material that needs to be diluted, proceed as fol-
lows:
– Take the measuring cup 22.
– Stir the spray material thoroughly.
– Fill a sufficient quantity of spray material into the spray-
material container 8. (see “Filling in Spray Material”,
page 17)
– Dilute the spray material by 10 % with paint thinner. Ex-
amples:
– Stir the spray material thoroughly.
– Carry out a test-spray run on a test surface. (see “Spray-
ing”, page 17)
When the spraying pattern is perfect, start the spray job.
or
When the spraying result is not satisfactory or when no paint
comes out, please continue as described under “Correction of
Malfunctions” on page 19.
Filling in Spray Material (see figures C1–C2)
f
Before any work on the machine itself, pull the mains
plug.
– Unscrew the container 8 from the spray gun.
– Turn the suction tube 10 so that the spray material can be
sprayed with almost no residue:
– Fill the spray material into the container and screw the con-
tainer firmly to the spray gun.
Starting Operation
f Observe 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.
f During 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.
f Pay attention that the base unit cannot draw in dust or
other contamination during operation.
f Make 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 16 on the base unit
toward the right to the stop.
It is recommended to start with the maximum air
flow. (“Adjusting the Air Flow”, see page 18)
– Pull the trigger switch 9 on the spray gun.
Note: When the base unit is switched on, air always flows out
at the nozzle 11.
Switching Off
– Release the trigger switch 9 and turn the control knob 16
toward the left to the stop.
– Place down the spray gun in the set-down port 17.
– Pull the mains plug from the socket outlet.
Working Advice
Spraying (see figures D–E)
Note: Observe the wind direction when operating the power
tool outdoors.
– Firstly, carry out a test-spray run and adjust the spray pat-
tern and the spray material quantity according to the spray
material. (For adjustments, see the following sections)
– Make sure to hold the spray gun vertical to the spray object
at a uniform clearance between 5 – 15 cm.
– Begin the spraying procedure outside the target area.
– Move the spray gun evenly cross-wise or up-and-down, de-
pending on the spray pattern setting.
An even surface quality is achieved when the paths overlap
by 4 – 5 cm.
– 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.
– End the spraying procedure outside the target area.
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.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.
