Starting and stopping
Starting
The tractor and the suction blower must always be
adjusted, so that the PTO shaft is straight, when the
blower is working. The suction blower must be placed
on a stable and horizontal foundation during operation.
The draw bar of the suction blower must always be
properly connected to the tractor during the work.
Start the blower by engaging the PTO, while the tractor
is running with the RPM as low as possible. Start up
slowly, until the PTO speed is max. 1100 RPM.
In order to avoid settling in the pipe system, it is re-
commended that the tractor is running with max. RPM,
before the conveying is started.
Stopping
It is recommended to stop conveying by removing the
intake nozzle from the material or open the slide on the
intake nozzle completely. Run the suction blower and
the piping system clean – then stop the suction blower.
Even in cases where the piping system is not
clean, when the suction blower is stopped, this will
normally not cause any problems. It is therefore
also possible to keep the intake nozzle in the same
position while starting and stopping the suction
blower.
Adjustment for maximum capacity
Start the suction blower.
Open the slide on the intake nozzle completely and
place the intake nozzle in the grain.
Then slowly turn the slide on the intake nozzle from
the fully open position towards the closed position.

open
The function of the slide is to ensure the correct
balance between air and grain in the pipe system.
This will give maximum capacity.
The correct balance between grain and air in the pipe
system depends on the conveying distance, i.e. the
total length of pipes connected to the suction and
pressure side of the suction blower.
The air regulator can be used as guidance for adjust-
ment of the correct balance between grain and air in
the pipe system.
