Inserting/Changing the Nozzles
For achieving a good material structure, preferably use twice the diameter of the
largest grain size.
1. Press the trigger (4) and lock the trigger while it is pressed using the trigger
stop (5).
2. Unscrew the safety ring (3) counter clockwise from the thread at the front of
the spray gun. Remove the installed nozzle and replace it with the required
nozzle (13), (14) or (15).
3. Screw the safety ring with the inserted nozzle back on the thread of the spray
gun.
4. Release the trigger stop.
Consistency of the Coating Material
For proper spraying results it is essential to agitate the coating material to a
smooth and lump-free consistency. Make sure the coating material is viscous but
not too thick so it can lightly slide down in the hopper gun.
When using textile plaster (e.g. cotton finishing), make sure the mass is viscous
(pasty). For checking the consistency, incline a plastic smoothing trowel to
approx. 45° and apply some coating material on the trowel. The mass should
slowly slide down.
Do not mix the coating material to thinner consistency if a fine surface structure is
desired. In this case preferably use a smaller nozzle or adjust higher air volume.
Note: Do not prepare the coating material inside the hopper (12) of the gun. Have
it prepared in a separate container instead. Always observe the provided notes
from the manufacturer of the coating material.
Operation
1. Clean the surface to be coated (ceiling, walls). The surface has to be clean,
dry and free of grease and dust.
2. Install the plastic hopper (12) on the gun body and properly secure it with the
hose clip (1).
3. Before starting to work, check the trigger (4) and make sure it moves freely.
4. The hopper spray gun is equipped with an R¼" air inlet (7). For your own
safety, do not permanently connect the spray gun with the air hose, but use a
quick air coupler instead. Seal the end of the quick coupler with one or two
layers of Teflon tape. The air should be regulated and filtered. Setup the air
