2.0 FREIGHT, DELIVERY, AND COMMISSIONING OF THE MACHINE
Attention: always work with working gloves!!
To facilitate the freight and the loading/unloading some parts can be dismantled: tires, drum and upper
chassis, legs….can be delivered dismantled.
The producer of the person in charge will fix the machine on the loading flat paying attention to the
instructions. To load and unload the machine it’s necessary to hang it on the 3 points indicated
with the symbol
For example as shown in the picture n. 15, 16 and 17
If the machine has been delivered with the mounted chassis pls hang the hooks the same way as above
described: 3 points with the symbol indicated above (example pict. 15, 16, 17).

11

The following instructions are relative to the machine with several dismantled parts. Follow up carefully the
relative instructions.
Controls to be made when you assemble the dismantled parts:
1) Mount the axles for the tires till the indicated point and
and tight well the bolts to fix them: pict. 11 pos. 30
You can adjust the tire’s width but be sure the axle ends
at least 3 cm (1.2”) after the bolt.
2) Mount the front jack pos. 40, fix it with the pin pos. 41 and adjust the height to get the chassis horizontal
by turning the jack handle. Mount the anchoring legs pos. 43 and 45 and fix them with the bolts pos. 42 and
44. If the jack and the anchoring legs are already mounted, make sure the pins are secure and that the bolts
are tight.
3) Mount the sprinkler pos 33 onto the adapter
and mount them on the sprinkler cart.
4) Fix the pipes for the width adjustment with
the bolts pos. 34
5) Fix the cart legs with the bolts pos. 35. When
the cart is on the ground control the
galvanized central pipe: it shouldn’t touch
the ground. In case it does, pls adjust the
cart legs longer.
6) Mount the cart towing bar and fix it with the
relative pin.
3.0 PREPARATION OF THE MACHINE FOR THE USE ON THE FIELD
CONTROLS TO BE DONE:
1) Check the gear box oil level and, if needed,
add the Sae 90 oil till the cap level

12

2) Lubricate the machine using any
greasing point on the machine
(look at the symbol page 3) and also the
crown gear on the drum as indicated in picture
21. Main points to lubricate: front jack, 2
anchoring legs, crown gear, drum bearing and
ring on turbine side, brake on the gear box.
It’s necessary to lubricate every 50
working hours.
2) Check the machine and the cart tire pressure: look at the proper pressure on the tires and if necessary
adjust it.
3.1 MACHINE SET UP ON THE FIELD
Attention: always work with the working gloves!!
1) To hook the machine with the tractor, lift it a bit by turning
the front jack handle. When the machine is hooked, lower the
chassis by turning the same handle the other direction till
when the complete towing bar weight is held by the tractor.
Take the front jack off and shift the machine to the next
spot (max transport speed is 10 km/h / 6 mph on flat roads).
2) Take the pin of the rotation stop (pict 12 pos 31) off and put the drum in the proper direction toward
the irrigation strip in order to get it aligned with the pull out direction of the pe hose: go on the back
side of the drum and look along the side of the drum its alignment with the pulling out direction (pict
26). Turn the machine on the turntable till when the drum is well aligned.
3) Put the pin of the rotation stop in its position to stop
the rotation (pict 12 pos. 31)

13

4) Lower the anchoring legs pos 43 and 45 with their relative handles to fix the machine properly on the
ground.
5) Put the hand wheel onto the pto shaft (pict 09 pos. 23), push it and turn a bit counterclockwise to
release the safety dog: lift it up to “pulling out position” as you see in picture 06. Let the sprinkler
cart drop down by turning the hand wheel. Always keep pushing the hand wheel when you use it.
6) When the cart is on the ground, take the hand wheel off, place it on its position on the machine and
secure it with its pin: picture 04 pos. 8. Then mount the cover on the pto shaft protection: picture 01,
pos. 4.
Pay attention to the hand wheel: never leave it on the pto shaft if you’re not using it as above
described! It’s very dangerous and can cause serious injuries:

14

9) Hook the towing bar of the sprinkler cart to the tractor (pict 14 pos.36) and pull out the cart along the
field with the max speed of 3 km/h (2 mph). Before you stop the pulling please reduce the speed smoothly.
There’s no alarm nor signal about the poly hose length so be careful to don’t pull it out too much!
Check if the sprinkler irrigation sectors are ok and eventually adjust them.
Disconnect the tractor and drive back to the machine.
Important: always leave at least one pe hose ring rolled on the drum and remember that along the first use
of the machine is necessary to pull out the complete pe hose not leaving more than one or two rings on the
drum : you’ll need to roll up all the pe hose with inside pressure.
10) Place the safety dog (non return tooth) in its
working position as shown in picture 06 pos 16
11) Connect the main line (hydrant head or pipeline outlet) to the machine by using the flexible hose. Open
the hydrant gate valve a bit till when the water is coming out from the sprinkler, then open it completely.
Control properly if the flexible hose couplings are well hooked before you open the hydrant: it’s a
pressurized system and could be dangerous if it’s not managed properly.
12) Engage the gear box shifting the knob pos 5
toward the sprinkler cart
13) Adjust the pull in speed by turning the computer
knob on the required speed.

15

3.2 MACHINE AUTOMATIC STOP
When the pe hose has been completely rewound and the sprinkler cart has been already loaded, the
disengagement rod connected to the automatic loading system (pict. 03 and 04 pos. 7) pushes the gear box
lever (pict. 03 pos.5) and disengages the gear box and the rewinding stops immediately.
The gear box remains disengaged (neutral position) till when it will be manually engaged. In case there
aren’t any low pressure/discharge/vacuum valves or high pressure/shut off valves on the machine the
irrigation continues, even when the drum doesn’t turn anymore.
3.3 SET UP CONTROLS
1) Check that the hose guide fork is positioned properly: it has to be well aligned with the pe hose when
the pe hose has been completely unrolled. In case of need please adjust the guide fork position as
follows:
- FIRST OF ALL STOP THE MACHINE!!
- take the elastic ring that fix the scroll bar insert off the block
Pict 27 pos 58
- take the insert off the block pulling it out from the greasing unit and
look carefully the direction (position) of the half moon below pict 28
pos 59
- Align the guide fork to the pe hose and put the insert inside the block
paying attention the half moon below is in the same direction as before.
- put the elastic ring back in its place and assure it’s well positioned all
around the grove
2) Check the engagement/disengagement lever pict. 03 pos. 5: to be
pull it opposite side of the sprinkler cart.
When the sprinkler cart has been lowered you can check if the
disengagement functions properly: push the lev pict. 03 pos 5 toward
the sprinkler cart and now push up the automatic cart lifting system
toward the machine till the end of its run to disengage the gear box.

16

If it doesn’t work properly, pls adjust the length of the threaded rod
indicated in pict. 03 pos.7
The lifting system should disengage the gear box when it arrives at the
end of its run.
ATTENTION: When you drop down the sprinkler cart releasing the safety dog (non return tooth) and
turning the pto shaft by means of the hand wheel you should use working protection gloves! Be sure nobody
is close to the sprinkler cart before you release the safety dog and drop down the sprinkler cart.
7) Check that the gear box pinion is aligned with the crown gear and
the teeth work well inside each other (allowed tolerance
0,5-2 mm). In case of any problem call the authorized dealer.
Stand clear from the crown gear and the pinion to check the
alignment and after you disengage the gear box you can test by
hand the pinion and the crown gears are adjusted properly: turn
the pto shaft with one hand left and right side. It should turn free
just a little bit both sides.
Due to safety reasons this operation can be done only when the machine has been stopped.
4) Check that all the bolts and screws are well tightened and that all the points indicated in this manual are
well lubricate.(FIG. 4)
(FIG. 5)
3.4 EMERGENCY PE HOSE REWINDING
The pto (power take off ) of the gear box can be used for the emergency rewinding of the pe hose: it will be
connected to the tractor by means of a cardan shaft.
1) Check that the gear box lever pict 03 pos. 5 is on neutral (push it opposite direction of the cart) because
otherwise you can cause serious damages to the gear box.
2) Connect the cardan shaft to the pto shaft of the gear box:
same position as the hand wheel pict 09 pos. 23

17

3) Start the pto shaft to rewind the pe hose.
Attention: when you use the pto drive the disengagement
(automatic stop) doesn’t work at the rewinding end. The
rewinding has to be stopped before the cart arrives against
the machine. The last 2 / 3 meters have to be rolled up
manually with the hand wheel. If you want to rewind them
with the tractor you can but you should roll it up very
slowly and stop the rewinding before the loading system
pushes the disengagement rod. Don’t forget that the safety
dog has to remain in working position before you start up
rewinding the pe hose: look and read pict 06.
Attention: if the pe hose has been totally pulled out, to avoid an excessive ovalization is better to put some
pressure inside before you start the rewinding.
3.5 USE OF THE MACHINE DURING THE NIGHT
The machine isn’t provided with an own electric energy and or lamp (except the small battery needed for the
computer): in case the machine has to be used with insufficient light it’s important to provide an adequate
lamp to follow up all the previously given instructions and avoid risks to persons and things.
4.0 MANTENANCE
1) Lubricate the parts indicated on the machine at least every 100 working hours: the main parts are the
crown gear, the drum hub, the scroll bar (hose guide system), the front jack and the rear anchoring jacks.
2) Change the gear box oil every irrigation season or at least every 3000 working hours.
3) Control periodically the tires pressure.
4) Lubricate the sprinkler every 400 hours: only some sprinklers have to be lubricated.
5) Lubricate the connecting joints of the disengagement rod every 400 working hours: pict. 25 pos. 49 and
pict. 26 pos.50
5.0 MACHINE STORAGE AT THE END OF THE IRRIGATION SEASON
1) If the winter temperature will drop below freezing in the place the machine will be stored, it’s better to
partially empty the pe hose. to do it you should pull out half of the pe hose as you do for a normal irrigation,
then you take the sprinkler cart off and then you rewind the pe hose by means of the pto shaft (look at point
3.4)
3) For a longer lifetime of the machine is suggested to clean the machine with a water gun and after it’s dry
again, look at the point that eventually need some antioxidant.
4) Lubricate all the indicated points as you do for the normal maintenance.

18

6.0 PROBLEMS AND SOLUTIONS
1 The machines can’t rewind the pe hose.
- Open and close completely the bypass by turning the Controller knob to “min” and to “max” and
listen/look if the motor is moving the ball valve.
-If it doesn’t turn check the Controller instructions manual and eventually control if the battery is charged
and if all the wires of the battery, the solar panel, the Controller and the electric motor of the bypass are well
connected. In case of need call the local service to change either the battery or the electric motor or to check
up the computer.
- If the bypass valve works properly and the turbine impeller doesn’t turn is possible that the turbine nozzle
is blocked by a solid: dismount the inlet pipe, check and eventually clean it.
Is also possible a long fiber as a rope or something similar went inside the turbine and has been wounded all
around the impeller: to check end eventually clean it you should take off the pto shaft protection and the
turbine cover.
- Also check the gearbox position: in case the drive pinion it’s too far or too much against the crown gear of
the drum, it will not move. To check it disengage the gear box, hold the pto shaft by hand (mandatory with
working gloves) and turn it back and forward: if the gearbox position is ok you should be able to move it a
bit and hear a clear “tac” “tac”….every time the pinion teeth match the crown gear teeth. Between the pinion
teeth and the crown gear teeth base you should have about 1 mm space.
- The gear box doesn’t work: if the turbine impeller turns (you hear the noise) but the drum doesn’t move, is
possible that the lever on top of the gear box isn’t well positioned and the gear box hasn’t been engaged.
Place the lever in working position (toward the sprinkler cart) naturally after the sprinkler cart has been
pulled out. If the turbine impeller turns, the gear box is well engaged and the drum doesn’t turn pls call the
local authorized service as maybe you have to change the gear box.
- The sprinkler nozzle is partially stopped and only some water comes out. Dismantle the nozzle and check.
- The filter (if ordered or mounted later on) at the machine inlet is full or at least dirty. Disconnect the
flexible supply hose and clean the filter.
- The sprinkler is always supplied with some nozzles of different sizes. Is possible to change the nozzle with
a smaller and/or with a larger one. The turbine nozzle is generally similar to the sprinkler nozzle. The
sprinkler nozzle you use depends on the available flow and pressure. Try different nozzles and for each
nozzle note carefully the sprinkler nozzle diameter, the pressure at the machine pressure gauge and the pull
in speed you can reach. This way the service will have a complete and clear picture about the situation and
will be able to help you.
- The pressure isn’t enough at the turbine/machine inlet: first of all disengage the gear box placing the lever
in neutral position. If the drum doesn’t turn try to increase the pressure or advise the local authorized service
and give all the data listed at the previous point.
- The pe 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.
2 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 pe hose has been pulled out, is on the field and is difficult to pull in. Wait that the soil becomes dry,
then shift the pe hose beside its position by a chain or a rope: put the chain under the pe hose and connect it
to the tractor lifting system and drive the tractor all along the pe hose shifting the pe hose beside. If you
haven’t a tractor you can put a wooden block under the pe hose every 6 m or less or you can do the
operation manually: the target is to detach the pe hose from the sticky place and also clean it.
3 If the pe 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 pe hose
with pressure (inside the pe hose): it’s possible to roll up the pipe by cardan shaft/pto or by turbine but
always with pressure inside to avoid the pe hose excessive ovalization.

19

7.0 IMPORTANT SUGGESTIONS
- During the machine transport the max allowed speed is 10 km/h (6 mph) on good level flat roads.
- Before you roll up the pe hose by cardan shaft pls be sure the gear box lever is on neutral position
otherwise the gear box can be strongly damaged
- The first time you pull the pe hose out to start the irrigation, you have to pull it out completely leaving only
1 or 2 rings on the drum.
- Any modification (that hasn’t been authorized in written form by the supplier) invalid the warranty
- If the pe lays on the soil, then it rains, it’s possible that the pe hose will stick to the soil so prior to start the
irrigation and rewind it, it’s mandatory to clean and shift it beside with a rope or chain as indicated at 6.2
above
- If the pe hose has been partially pulled out, probably some rings became loose on the drum and it’s
necessary to pull it out completely to roll it up again so it will be all well tightened.
- If both drum alignment and pe hose complete rewinding with pressure inside the hose have been done and
you still have problems, pls call the local authorized service.
- Sprinkler cart: only the tires together with the pe hose have to support the cart weight.
- Don’t pull out the pe hose or achieve any other function on the machine when the hand wheel is mounted
on the pto shaft of the gear box. Always take it off the shaft after use.
- Don’t use the machine when the protections aren’t mounted and always stand clear from any possible
squeezing point.
IMPORTANT NOTE: if these instructions will not be correctly followed, if non original parts will be
installed or in case of not written authorized modifications the warranty is totally invalid. In this case the
producer is not more responsible for any risk, injuries and damages may happen to the operator, to third
parties.

8.0 ADDITIONAL RISKS
Even if IRRILAND pays attention to avoid dangers for the user during the design and the construction with
functions and guards generally safe, it’s always possible that some additional risk appear during the use of
the machine.
1) Risk to hook and displacement between the drum and the structure during the structure and the drum rotation. This
risk is higher during the machine placement and during the pe hose pulling out and rewinding. Be sure nobody is next
to the machine during the rotation before the anchoring legs have been fixed and during the pe hose pulling out and
rewinding. Only the authorized persons can remain close to the machine, nobody more.
2) Flattering and trapped risk between the pe hose and the drum along the rewinding. Avoid any contact with the pe
hose during the rewinding and be sure no authorized persons can’t access to the area.
3) Overturn risk: along the machine shifting and freight there’s a serious risk to overturn the machine. The risk
increases a lot if the slope is more than 6°. Drive with particular attention, don’t increase the speed and drive through
the best parts of the road. In case of excessive risk drive back and look for other way.
4) Risk of upper frame sudden rotation: when you place the machine especially in a slope area the upper frame could
turn suddenly: to work with no risks in this situation the client has to hold the upper frame from the middle height of
the drum before he removes the pin to stop the rotation.
5) Overturn risk during the upper frame rotation: Always load the cart (or leave it loaded), than position the rear
anchoring legs with their points just some cm from the soil, check the front jack is well established and turn the upper
frame. In case the machine isn’t stable you need to fill it up with water to increase the stability, before the upper frame
rotation.
6) Electricity risk: during the irrigation the sprinkler throw can match the power cables. The risk of a very dangerous
electric shock through the metal structure is very high. Be sure there aren’t electric lines in the sprinkler radius all
along the pull.
7) Risk to impact directly the sprinkler throw. When the machine will be started and the water will be supplied to the
machine, the throw can start suddenly and strong. It’s always better to release the flow partially till the water pass
through the sprinkler and then increase it till the normal working flow. Anyway be sure nobody is next to the sprinkler
when you start the machine.
8) Shock risk against plugs and couplings of the machine and the flex hose. Don’t open nor disconnect the plugs and
the couplings with the pressure inside. Be sure there’s no pressure before you release any plug or coupling. Control
them carefully before you get pressure in the machine.
9) Risk of incidents on roads. Set up the sprinkler cart and the sprinkler in a way that the water throw will not wet a
transit area to avoid damages to persons and things.
9.0 SHIFTING OF MACHINES CONNECTED TO PRESSURISED MAIN LINES
When the machine has finished the cycle, please reduce the pressure at the machine as follows:
1) Shut off the hydrant valve (where is connected the flex supply hose of the machine)
2) When the pressure gauge indicates pressure “0” and there’s no more pressure in the flex supply hose you
can disconnect the couplings of flex supply hose and shift the machine to the next position.
