RM Speedy-Rain 401 Instructions D'utilisation page 16

I) Adjust the sprinkler sector (8). The sprinkler has to cover the wished part (we suggest a sector of 180)
not wetting the Speedy Rain.
L) The stop happens authomatically at the end of the rewinding by the release of the traction system,
lifting up the engine shoe (12) by the driving gear (5). On the machines with Aquastop (Optional) the
stop happens by closing the inlet water. In order to open again the Acquastop valve, it is necessary to
escape the feeding water (for example by disconnecting the quick joint 15).
M) We suggest to take away the drawbar during the rewinding, to avoid the machine shifting from the initial
position.
REGULATING HOSE REWIND RATE
Hose rewind rate depends on water pressure but can be regulated with the by-pass valve (17) on the turbine. For
precise regulation, turn the by-pass valve (17) just a couple of degrees. For larger rewind rate increase or
decrease, regulate the drive gear. To do this, stop the machine by shutting off the water supply. Remove the drive
shoes (12) and use the wrench (9) in the tool kit to remove screw (18) on the cylinder mounted on ball bearings.
To increase the rate, put the screw into the outermost tapped hole on the plate. To decrease the rate, put the
screw into the innermost tapped hole on the plate. Tighten the screw all the way, close the casing and replace
the wrench in its holder on the casing. Turn the water supply back on and fine tune the rewind rate with the by-
pass valve (17).
It is always best to regulate the machine as much as possible with the by-pass valve open since this causes less
loss of pressure in the turbine and improved machine performance.
ATTENTION
MAKE THIS ADJUSTMENT WHEN THE MACHINE IS STOPPED DO NOT CLOSE WATER
SUPPLY. IT COULD BE DANGEROUS!
ATTENTION
It is absolutely forbidden to work on land with abrupt drops.
