Table of fan rotation speeds
The table of fan rotation speeds can be used as
reference for most of the applications at 12 km/h.
Due to the vast variety of drilling and operating
conditions the specification of exact and binding
rotary speeds is not possible.
With higher drilling speeds the rotary speeds
must be slightly increased.
Fan setting, seed transportation and
seed placement must be checked on
all coulters when starting sowing, and
also at regular intervals when working
on large areas.

Checks and maintenance
¾
Ensure a free leak oil return pressure of
max. 5 bar.
¾
Clean the air intake grid at regular intervals to
prevent a restriction in air flow and resulting
blockage.
¾
Clean any dirt or deposits from the fan blades
to prevent unbalance and damage to impeller
and bearing.
¾
Retighten the clamping taper on the fan shaft
(see chapter Fan Flange).
1
Restrict air quantity for rape with the distribu-
tor valve.
