Ocmis Irrigazione S.p.A. – INSTRUCTION AND WARNING MANUAL – Translation of Original Instructions
MUMR-R1.02 .EN - 31/07/2015
CHAPTER 6 - Use and Operation
Note: During factory testing this calibration is performed to achieve the following conditions:
•
with the hose completely wound on the machine the by-pass
butterfl y valve is almost completely open in order to let water fl ow directly to the
raingun without any reel rotation;
•
with the hose completely unwound onto the ground the by-pass butterfl y valve is almost completely closed in order to let water move the reel for
hose reeling in rotation.
If the machine's speed changes noticeably during the hose retrieval stage, it is required to act as shown on the previous page.
During irrigation it is recommended to keep the hose winding on the reel under control and if necessary repeat the steps set out in the fi rst paragraph
of chapter 6.5.
6.6.2
QUICK HOSE WINDING
Should it be required to reel the hose back in rapidly, follow the instructions below:
Note: If the unwound hose has remained on the ground for some time and has been exposed to the weather, it is certainly stuck to the ground, which
is why it is essential to detach the hose from the ground prior to starting the machine, either by moving it by hand or running a rope underneath it for
the entire unwound length.
CAUTION
If the machine is started with the hose stuck to the ground, it is certainly going to be irreparably damaged.
1) Move the lever on the turbo gearbox into the STOP position.
2) With a certifi ed cardan joint, in good state of repair and fi tted with regular protection devices, connect the tractor's PTO to that of the machine
which is located on the gearbox (see ref.10 par.2.1).
3) IMPORTANT: If the length of the hose to be reeled in is over 30% of the total length, it is essential to pressurise or maintain pressurised the water
inside the hoses as in normal irrigation. This is in order to prevent certain out-of-roundness of the hose, leading to unevenness in looping on the
reel.
4) Actuate power take off rotation from the tractor, paying attention to the direction of rotation and maximum number of RPMs, which must not exceed
the limit of 540 g/1.
5) Rapid hose reeling in with shaft drive does not include the automatic stroke end stop as in a normal work cycle, it is therefore essential to stop
rotation of the power take off when 2 or 3 metres of unwound hose remain on the ground.
6) Remove the shaft drive between tractor and machine.
7) Engage the handwheel (see ref. 49 par.2.5.1) in the machine's power take off and rotate it manually to reel in the last few metres of hose still
unwound.
8) Interrupt water delivery from the pumping station.
Note: If the machine remains placed in the current position awaiting subsequent irrigation of the same fi eld, at the time of the next irrigation just repeat
the operations as per paragraph 6-4 starting from item 7. If however the work place changes, the operations for preparing to tow must be completed,
as set out in chapter 6.7 starting from item 2.
6.7
END OF WORK AND PREPARING TO TOW
The machine is stationary when: the hose is all reeled in, the stop bracket (located on the hose near the coupling fl ange to the raingun trolley) has
actuated the lower bar of the corrector due to stroke end, and lever 2 located on the gearbox has automatically moved to the 0 or STOP position. It
is therefore required to proceed as follows:
1) Stop water delivery from the pumping station if it is not equipped with automatic stop.
2) Let water fl ow for the water pressure to be reduced to zero.
3) Disconnect the water delivery hose.
4) Ensure the raingun trolley is positioned so that it may be lifted.
5) Lift the rear anchors and the raingun trolley.
6) (only for MRR and R1AT15 ) remove the turret rotation stop pin and manually rotate the turret in the transport position then lock by inserting the
pin in the suitable seat.
7) If the machine is provided with Road Use Approval and is to be towed on public roads, it is essential to insert the mechanical stops on the
extensions.
The Registration Document must also be referred to in order to apply the statutory requirements.
8) For towing refer to the instructions under 6.3.
