Operation
Intended Use
The air hopper spray gun is intended for applying different types of wall and
ceiling finishes such as natural wall coatings, silicate plaster, sand finish
textures, Latex textures, reinforcement adhesives, snow flake textures, etc. It
is not designed to apply regular wall paint or thin coatings of any kind.
The intended use also included an operation following the operating
instructions.
Any use beyond these parameters (different media, applying force) or any
changes (reconstruction, no original accessory) can lead to serious risks and
is regarded as use that contrary to the intended purpose.
Before first Use
Unpack the air hopper spray gun and check it for any damage in transit. Do not
use the tool if it is damaged.
Dispose of packaging materials or store it out of reach of children.
Air Pressure and Air Volume
The air hopper spray gun requires clean and oil-free air. Therefore do not use
an oil-fog lubricator within the air supply system.
If possible, only use compressed air hoses for the air supply that previously
have not been used with other air tools which required an oil-fog lubrication
system.
Operate the air hopper spray gun with a pressure of 1.7 – 6.2 bar. When using
a higher pressure than the max. permitted pressure of 6.2 bar for operating the
air tool, its self life will be reduced drastically. Operate the air hopper spray
gun using a compressor with an air suction capacity of at least 200 l/min. The
ideal capacity is provided by compressors with a suction capacity of 200 –
300 l/min.
The higher the airflow is adjusted, the finer the spray pattern will be. When
working with too much air, the grains of sand (in plaster) become dissolved
from the coating material and rebound from the wall. This will lead to loss of
coating material and dirt.
Only use air hoses with an inner diameter of at least 9 mm. When setting up
the air pressure, always keep in mind that the pressure will decrease by
approx. 0.6 bar when using a 10 m long hose with an inner diameter of 9 mm.
