6.0 PROBLEMS AND SOLUTIONS
1 The machines can’t rewind the polyethylene hose.
- For machines with computer pls also follow the instructions on the computer manual.
- Open and close completely the bypass by moving its lever. If the turbine impeller doesn’t turn is
possible that the turbine nozzle is blocked by a solid: dismount the collector under the turbine and
clean it. Also take off and check the impeller: need to dismantle the turbine cover (and the pto
protection) with a spanner and a tube key and then the impeller by using an extractor.
- The gear box doesn’t work: if moving the bypass lever (or adjusting min to max speed on the
computer) the turbine impeller turns (you hear the noise) but the drum doesn’t move, is possible that
the levers on top of the gear box aren’t well positioned. Place the left side lever in position 1, 2 or 3 as
indicated at point 3.1 12) at page 17 of this manual. Then place the right side lever in pos 1 (toward
the sprinkler cart) , pict 14 pos 32.
- The sprinkler nozzle is partially stopped and only some water comes out. Dismantle the nozzle and
check.
- The filter at the machine inlet is stopped or at least dirty. Disconnect the flexible supply hose and
clean the filter.
- The sprinkler is always supplied with some nozzles of different sizes. If possible change the sprinkler
nozzle with a larger one.
- The turbine nozzle is generally 2 mm (0,8”) larger than the sprinkler nozzle. In case the flow is low
and you can use only a small nozzle on the sprinkler you can also change the turbine nozzle. In this
case you can mount a turbine nozzle with the same diam of the sprinkler one or just 2 mm ( 0,08”)
larger.
- The pressure isn’t enough at the turbine/machine inlet: first of all disengage the gear box placing the
right side lever in neutral position “0” and change the gear to a lower one (from 3 to 2 or from 2 to 1)
with the left side lever. If the drum doesn’t turn try to increase the pressure.
- The polyethylene hose has been pulled out, the gear box is properly engaged and all the above
mentioned parts have been checked. The gear box may be damaged: call the local authorized service.

The machine isn’t stable and try to move.
- The rear anchoring legs haven’t been adjusted properly place the machine better and especially fix
properly both rear anchoring legs in the ground.
- The polyethylene hose has been pulled out, is on the field and is difficult to pull in: wait that the soil
becomes dry, then shift the polyethylene hose beside its position by a chain or a strong rope. Put the
chain (or the rope) under the polyethylene hose and connect it to the tractor lifting system and drive the
tractor all along the polyethylene hose shifting it beside. If you haven’t a tractor you can do this
operation manually or you can put a wooden block under the polyethylene hose every 6 m (20’) or
less.
3 If the polyethylene hose hasn’t been rolled up properly pls check the drum is well aligned with
the pulling out direction, pull the hose out and follow up the instruction to align the guide fork and
then roll up the polyethylene hose with pressure (inside the hose). It’s possible to roll up the hose by
cardan shaft/pto or by turbine but always with inside pressure to avoid the polyethylene hose
excessive ovalisation
7.0 IMPORTANT SUGGESTIONS
- During the machine transport the max allowed speed is 10 km/h (6 mph) on good flat roads.
- Before you roll up the polyethylene hose by cardan shaft pls be sure the right side lever on the gear
box is on neutral position of the gear box, otherwise the gear box and other parts can be strongly
damaged
