Delivery rate adjustment by 4-step electronic system (Illus.
Tapping the electronic pushbuttons reduces the stroke rate by one step at a time, from
max. delivery (100 %) in 4 steps to 12 %.
With the switch on minimum (12 %), repeated tapping will reset the 100 % stroke rate.
The electronic pushbutton can be used whether the unit is running or not.
Delivery rate
Fine adjustment knob maximum: electronic pushbutton 100 % = max. 350 g/min
Fine adjustment knob minimum: electronic pushbutton 12% = min. 25 g/min
NOTE: Depending on the material and dilution the sprach pattern can be controlled by
the fine adjustment knob (in addition to electronic adjustment). For optimum
setting a test spraying operation is advisable. For details refer to handling table
page 15.

Spray Technique

● 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.
● Test the spray gun on cardboard or a similar surface to find the correct setting.
● Do not spray the vessel empty. The suction tube should always be immersed in li-
quid. If air is sucked in, larger drops may result.
● When spraying, hold the spray gun in a horizontal position. Use the flexible nozzle
extension (Illus.
or downwards (e.g. an unhinged door laid on the floor).
● Begin spraying outside of the spray area and avoid interruptions inside the spray
area.
● Do not apply too much paint during one spraying operation. First apply a thin layer
and allow to dry briefly before applying a covering layer. This is especially important
with vertical surfaces to avoid paint sags.
● The distance from the nozzle to the object to be sprayed depends on the delivery
rate. With a low delivery rate it is possible to go very close to the object. This
reduces the amount of spray mist.
● The spray gun should be worked as evenly as possible during the spray operation.
Accelerating or slowing down during the spray operation causes an uneven spray
pattern, spattering, dripping and orange peel.
● 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 (Illus.
● To achieve optimal spray results, spray back and forth over the surface (Illus.
