GENERAL INFORMATION ABOUT THE
APPLICATION TECHNIQUE
7.1
SPRAYING TECHNIQUE
While spraying hold the spray lance at a uniform distance of
30 – 60 cm from the object. Otherwise the spray pattern will be
uneven.
The spray pattern depends on the coating material, viscosity,
tip size, convey capacity and amount of atomizing air.
Examples:
Fine texture
large amount of atomizing air
Rough texture
small amount of atomizing air
Higher convey
larger amount of atomizing air
capacity
•
Test the desired texture on a test surface.
•
The lateral limit of the spray jet should not be too sharp.
The distance between the spray lance and the object
should therefore be selected correspondingly.
•
The spray edge should be gradual in order to facilitate
overlapping of the next coat.
•
If the spray lance is moved parallel and at an angle of 90° to
the surface to be coated, the paint mist is minimized.
Grains and pigments with a sharp edge result
i
in a high rate of wear of the pump, mortar hose,
material tap and tip.
When using the mortar hose while working on
i
scaffolding, it is best to always guide the hose
along the outside of the scaffolding.

SHUTTING DOWN AND CLEANING
8.1
CLEANING THE MORTAR HOSE
1. Pump until receptacle is empty.
Attention
2. Switch off mortar spraying machine and compressor.
3. Close material tap on spray lance.
4. Remove the texture tip from the spray lance and clean it.
5. Put water in the container and hold the spray lance over
an empty bucket.
Attention
6. Set delivery volume controller to „5".
7. Open material tap on spray lance.
8. Pump material out of hose into container until the material
exiting the hose is just a thin liquid.
9. Close material tap on spray lance.
10. Decouple mortar hose from pump unit.
11. Decouple spray lance from mortar hose.
12. Insert cleaning ball into mortar hose and reconnect mortar
hose
13. Set selector switch to "F".
Do not clean the motor and control unit of the
mortar spraying machine moistly. And certainly
do not spray down the unit with high-pressure
cleaners or high-pressure steam cleaners. Danger
of short-circuits caused by water ingressing.
Do not let the mortar spraying machine run dry.
Switch the device off immediately if no more
material comes out of the tip or if the spray line
becomes irregular.
Possible reasons for the problem and how to
correct it can be found in the chapter called
„Eliminating faults".
Do not let the mortar spraying machine run dry.
During the cleaning process, ensure that there is
always enough water in the container.
The mortar hose must be pressureless.
If necessary, set the selector switch briefly to "R"
(reverse).
Watch the manometer ––> 0 bar.
Wear safety goggles.
