pressure according to the parameters supplied with the material to be
processed and according to the technical data.
5. Have an assistant pour the material to be processed into the top of the hopper.
The hopper has a max. capacity of 5.7 litres. Do not fill more than ¾ of its
capacity.
6. Firmly hold the handle (8) of the gun with one hand and the hopper handle
(11) with the other hand. Press the trigger (4) to start spraying. Release the
trigger to stop spraying.
7. Use the fluid control knob (9) to preset the operating range of the trigger (4).
Turning in the fluid control knob clockwise will decrease the operating range of
the trigger. This way it can be pressed in less far.
8. After work, disconnect the air hopper spray gun from the air supply and clean it
as described in chapter "Cleaning and Maintenance".
Notes:
 Perform test runs on some test pieces. This way you can determine the
optimum spraying strength and the spraying distance.
 The movement speed of the spray gun depends on the size of the nozzle, the
distance to the surface (wall or ceiling), the consistency of the coating material
and the used air pressure.
 Do not spray in an arc on the surface and do not interrupt spraying as this will
lead to uneven or too little coating material distribution onto the surface. Most
of the coating products are fast-dry materials.
 Always keep the spray gun in a constant distance to the surface. Hold the
spray gun vertically to the surface to be sprayed and move the spray gun
evenly and in parallel lanes from one side to the other.
 Before cleaning the hopper spray gun, check the work first. After work empty
remaining coating material into an appropriate bin. Properly dispose of coating
material that is no longer needed.
 Fresh treated surfaces must not be exposed to direct sunlight, to very high or
low temperatures, wind, dust, water or rain.
 Pay attention to the air hose while operating the hopper spray gun. Hold the
hose with one hand while you are operating the spray gun with the other hand.
If necessary, ask an assistant to take care of the air hose. The hose must not
be bent and do not step on it.
