Manual for

BAUER RAINSTAR A3

18

The change-speed gearbox consists of toothed wheels that
reduce the turbine speed. Reel drive stop at the end of the
irrigation strip is ensured by disengagement of the toothed
clutch.

The gearbox in connection with the belt steps adapt perfectly to existing operating conditions. As a
result the following retraction speeds (m/h) can be reached:

834 9277

12 m/h 8 - 25 m/h 18 m/h

Removal of the drive cover for service jobs or change of transmission only is
permitted when the PE-pipe has been slackened completely! Move the gear shift
lever to shut-off position! This shut-off position also must be used for the transport of
the machine on the roads!

WARNING!
