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
Rough texture
Higher convey capacity –> larger amount of atomizing air
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 there-
fore be selected correspondingly.
The spray edge should be gradual in order to facilitate over-
lapping 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.
Note:
Grains and pigments with a sharp edge result in a high rate of
wear of the pump, mortar hose, material tap and tip.

SHuttING DOWN AND CLeANING
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.
8.1
CLeANING tHe MORtAR HOSe
• Pump until receptacle is empty.
Important: Do not let the mortar spraying machine run
dry.
• Switch off mortar spraying machine and compressor.
• Close material tap on spray lance.
• Remove the texture tip from the spray lance and clean it.

–> large amount of atomizing air
–> small amount of atomizing air
• Put water in the container and hold the spray lance over
an empty bucket.
Important: Do not let the mortar spraying machine run
dry. During the cleaning process, ensure that there is al-
ways enough water in the container.
• Set delivery volume controller to „ 5".
• If using automatic lance, open material tap on spray lance; if
using pneumatic lance, set selector switch to "F".
• Pump material out of hose into container until the material
exiting the hose is just a thin liquid.
• If using automatic lance, close material tap on spray lance; if
using pneumatic lance, set selector switch to "A".
the mortar hose must be pressureless.
If necessary, set the selector switch briefly
to "R" (reverse).
Watch the manometer ––> 0 bar.
Wear safety goggles.
• Decouple mortar hose from pump unit.
• Decouple spray lance from mortar hose.
• Insert cleaning ball into mortar hose and reconnect mortar
hose
• Set selector switch to "F".
• After a few seconds the cleaning ball is emitted from the
spray lance.
• Depending on the processed coating material, repeat the
cleaning process 3 – 4 times.
the mortar hose must be pressureless.
If necessary, set the selector switch briefly
to "R" (reverse).
Watch the manometer ––> 0 bar.
Wear safety goggles.
• Set selector switch to "A".
• Decouple mortar hose from pump unit.
A further cleaning option is to use the clean-
ing adapter (accessory).
This cleaning adapter can be connected to a
water hose or a tap by means of the claw cou-
pling.
Insert cleaning ball into the mortar hose. Cou-
ple the mortar hose to the cleaning adapter
and rinse through with water.

CLeANING tHe DeVICe AND RePLACING tHe
StAtOR
• Clean mortar spraying machine.
To do so, pump graphite pump sliding means or water mixed
with dishwashing liquid through the pump.
