Bauer Rainstar TX Plus Series Operating Manual page 25

On RAINSTAR models with 90 mm PE-pipe diameter (basic units 85 TX and 90 TX ) the turbine is fitted with a
special connecting bend as well as a three-stage V-belt drive.
This design allows low retraction speeds and as a result precipitation rates of up to 50 mm, even in case of large
flow rates (up to nozzle dia. 30 mm).
For this purpose you screw out the regulating screw (1) which is easily accessible, and screw it back into the hole
after turning it around 180° with the sealing cone side pointing outward.
As a result, part of the water flow is redirected above the turbine's impeller.
This reduces the output of the turbine and consequently also the retraction speed.
Moreover, the 3-grooved V-belt pulley provides an additional reduction stage so that the low retraction speed
required for such extreme conditions can be reached (for 50 mm precipitation height).
I
WARNING!
Switching from I to II or the other way round is easy to do with the gear shift lever when the cart is lowered and the
turbine rotating.
Operating manual for BAUER RAINSTAR series
Never remove the drive cover for service work or change of the transmission unless
the PE-pipe has been completely slackened! Put the gear shift lever into the shut-
off position! This shut-off position applies also for transporting the machine on
streets and roads!
