Starting Operation
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.
Pay attention that the base unit cannot draw in dust or
other contamination during operation.
Make sure never to spray on the base unit.
Switching On
– Plug the mains plug into a socket outlet.
– Grasp the spray gun by the handle and point it at the spray
surface.
– Firstly, press the On/Off switch 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 press the On/Off switch
18.
– 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.
Adjusting the Spray Pattern (see figure F)
Never actuate the trigger switch 9 while adjusting the
air cap 2.
– Loosen the union nut 3.
– Turn the air cap 2 to the requested position.
– Firmly retighten the union nut.

Adjusting the Spraying Capacity (see figure G)
– To adjust the requested spraying capacity, turn the thum-
bwheel 5:
I: Min. spraying capacity,
IIII: Max. spraying capacity.

Adjustment
Too much material on target
The spraying capacity must
area:
be reduced.
– Turn the thumbwheel 5 in
Not enough material on target
The spraying capacity must
area:
be increased.
– Turn the thumbwheel 5 in
Placing down the Spray Gun (see figure H)
For breaks, the spray gun can be hung in the holding clamp
16.
– Hang the spray gun with the union nut 3 into the holding
clamp 16.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull the mains
plug.
Cleaning (see figures I–K)
Proper cleaning is the requirement for flawless operation of
the spray gun. Improper or lack of cleaning voids warranty
claims.
Always clean the spray gun and the container with the respec-
tive diluting agent (paint thinner or water) for the spray mate-
rial being used.
Never immerse the complete spray gun into the cleaning
agent.
