―Inhalation of oil mist may cause lung disease.
―Leakage of oil under high pressure is dangerous, an oil jet can enter the
skin, eyes, etc.
―If a hydraulic system leak is found, stop the system immediately and
rectify the fault.
―Note that due to operation, the oil may be 70degrees Celsius or even
hotter. This can lead to a risk of scalding during separation.
―IMPORTANT.Maximum battery charging power is 2 amps. Charging
more than 2 amps may cause the battery to crack. The battery must be
charged at a temperature between 0 °C and +40 °C. Avoid sparks and
ames on and around the battery.
―Do not short circuit the battery.
―Never disassemble the battery.
―If you come into contact with the battery's sulphuric acid, wash

thoroughly with water and seek medical attention immediately.
―Pay attention to the battery compartment. If there are cracks,
deformities, electrolyte leakage, etc., replace the battery immediately.
―If the battery is dirty, clean it as soon as possible.
―Disposal of oil spills:
―If oil spills are found, they should be cleaned up immediately with rags
or oil absorbent powder.
―Spilled products, as well as rags and powder used for oil spills, must
be stored in sealed metal containers and delivered to the municipal

Operating instructions
Starting the FM4900H
Move the machine to the eld in the transport position. When the machine
is at the crop to be irrigated, disconnect the tractor from the front drawbar.
Connect the tractor to the rear drawbar. Insert the electric brake connector
in the female connector for the tractor lights. The machine then winds up in
the crop and stops.
Disengage the stop pawl at the hose drum.
The stop pawl at the hose reel is disengaged when laying the hose.
Remember!! When starting the machine on falling ground, you must be
VERY careful not to disconnect the tractor from the machine until the
machine has been put into gear, otherwise the machine may run away.
Safety stop
During irrigation
During transport
Secure the long ground spikes. Lower the drawbar over the hose , and
release the safety stop so the hose reel runs on the hose.
The machine should be unwound completely at least every 3rd time.
Before starting to unwind the machine, reset PROGRAM RAIN. To do this,
press the TOGGLE SWITCH located on the side of the electric box upwards
(reset).
When unwinding the machine, the TOGGLE SWITCH must be in the centre
(unwind) so it cannot reset on the way out. After unwinding, press the
TOGGLE SWITCH down (operation).
ALWAYS REMEMBER that the TOGGLE SWITCH must be pressed down
during operation, otherwise the machine will not move.
Unwind the machine at max. 5 km/h to keep the hose tight on the drum at
all times with the electric brake. If you do not lay the hose straight out be
very careful to ensure that the hose is always tightened on the hose drum.
Preparing the machine for irrigation
Disengage the stop pawl at the hose to enable operation.
Also remember to release the electric brake and disconnect the electric
brake connector from the tractor.

(Lever "2" pulled out)
Attach the charge hose to the hydrant. Then open the hydrant, start the
pump and irrigation can begin.
When starting irrigation, see the operating instructions for PROGRAM RAIN.
Put the machine in gear. (Remember to select the right gear for the speed
you want to drive at.) (Refer to table below or on the machine for electrical
control.)
Preparing the machine after irrigation
After each irrigation, open the bypass valve (Lever "1" must be pushed in)
to get the gearbox out of gear (Lever "2" pulled out).If there is tension in
the rear axle assembly, use a fork wrench to turn the input shaft to release
the coupling.
ALWAYS REMEMBER THAT THE COUPLING MUST BE RELEASED
(COUPLING LEVER PULLED BACK) WHEN
THE MACHINE IS NOT MOVING BY ITSELF.

Water can only be drained from the machine with air.
Use the special compressor for draining.
REMEMBER!!
Open the lter coupling.
Open the valve in the base of the turbine
On machines with high pressure stops START to open the main valve and
allow the water to ow out freely. (Disconnect battery lead so stop valve
does not close again.)
Remove the battery and do not install it until the next time you use the
machine.
Lubrication of:
Front wheel hubs, front spindle, hose guides, bearings on hose guides,
wheels.
Check for water in the oil in the rear axle assembly and hydraulic tank. Oil
in the rear axle assembly / at gear should be changed every 1,000 hours.
Hydraulic oil and lter should also be replaced every two years.
Lubricate the steering, roller chain for hose guides, roller chain for forward
traction, cross track shaft for hose guide with water-repellent grease.
Check tyre pressure:
Guide pins should be replaced every year.
Check the following before calling a technician:
1. If the machine is irrigating, but not moving:
a. Check that machine is in gear.
b. Check if it is performing pre-irrigation or post-irrigation. (can be
seen on the display under menu 3.)
c. Check if pressure drop valve is closed.
d. Check that end stop sensor is in place.

e. Check that toggle switch is in operation position.
f. Check that decoupling valve is closed (for hydraulic motor).
g. Check that lter at turbine outlet is not blocked.
h. Check that turbine can turn easily.
2. If the machine does not wind up the hose properly, it may be
that:
a. The hose guide needs to be adjusted:
To adjust the guide, remove the chain from the hose guide to
the cross track shaft. Then turn the cross track shaft until the
hose guide ts the hose again. Then t the chain.
b. The guide pin is worn and needs to be replaced.
c. There is not enough pressure on the drum winder. (call a
technician).
3. Front and rear forced steering are not aligned and forced steering
is sprung on impact:
a. There is a leak at the coupling or assemblies, so the oil has
drained out, leaving air in the system.
b. The system must be vented. (call a technician).

See GSM chapter for details.
START:
The turbine can only start if the magnet is aligned with the end stop sensor (or end stop sensors). See menu 3 for control of the STOP SENSOR. Press the
START key to turn on the water. The regulator valve for bypass around the turbine then closes. (Turbine starts). If the end stop sensor is not in place, only the
main valve can be opened, which then immediately closes again. Used to relieve pressure before removing charge hose from hydrant.
DEFERRAL OF START TIME
First press the STOP key to shut o the water supply. Then press the MENU key 3 times and PROG 3 times. The start time can be set using the "+" and "-" keys.
Finally, select pre- and post-irrigation. To exit, press MENU.Info: The clock can only be set forwards.
STOP:
When the magnet is removed from the end stop sensor, the turbine stops and the main valve shuts o the water (turns on the water at negative pressure). If
post-irrigation is selected, rewinding stops when the magnet is removed from the sensor. When the post-irrigation time has elapsed, the main valve closes.
When the STOP key is pressed, the turbine stops immediately and the main valve shuts o the water, regardless of whether post-irrigation is selected.
SUPERVISION:
Program Rain has a built-in supervision system. The supervision system will be activated if for any reason the machine has water in the same location for
longer than a specied time. This time is factory-set to 20 minutes. If the time is set to 0, there is no supervision. (See constants on page 17 for setting the
supervision time.) If speed supervision less than 50 % of pre-selection is required, select speed supervision together with the above time.
SPEED:
The speed is set using the "+" and "-" keys. First count up in steps of 0.1 m/h. After 10 steps, count up in steps of 1 m/h. The speed can be changed at any
time during irrigation. If the speed changes during irrigation, the dose and time for the remaining irrigation will be calculated immediately based on the new
speed.

19
PRE-IRRIGATION:
If pre-irrigation is required, press the PRE- key. The pre-irrigation time is calculated as 8 x the time to move 1 m at the current speed. The constant can be
changed individually for pre- and post-irrigation. (See constants). If pre-irrigation is selected, the machine will move forward approx. ½ m, after which the
machine will stop and stand still for as long as pre-irrigation is performed. Menu 2 shows the number of minutes remaining of the pre-irrigation time. If you
want to cancel pre-irrigation, press the START key. This will cancel both pre- and post-irrigation and the turbine will start.
POST-IRRIGATION:
If post-irrigation is required, press the POST- key. The post-irrigation time is calculated as 8 x the time to move 1 m at the current speed. The constant "8" can
be changed individually for pre- and post-irrigation. (See constants on page 17). Post-irrigation starts counting down when the magnet is removed from the
stop sensor. When the stop sensor is activated, the turbine stops and post-irrigation starts counting down (see menu 2). When the post-irrigation time has
elapsed, the main valve closes. (Opens in installations with negative pressure stops). For machines with mechanical end stops: The turbine stops when the
stop sensor is activated. When the post-irrigation time has elapsed, the turbine starts and the machine moves to the mechanical end stop. Press START to
cancel post-irrigation. If constant "8" (early stop) is selected, the machine will stop when it reaches the selected distance.
PROGRAMMING 4 DIFFERENT SPEEDS:
The hose must be unwound before programming, so the computer knows the number of metres in the irrigation lane. The following example assumes that
the unwound hose is 400 m. Press the PROG key 3 times and the display will show:
The desired speed can now be selected, in this case 25.0 m/h. Press the PROG key and the display will show:
The desired distance can now be selected, in this case 300 m. Press the PROG key and the display will show:
Now that the rst zone is programmed, apply the same procedure to all 4 zones. Zone 4 automatically ends at 0. When zone 4 is programmed, press the
PROG key again and the display will show:
If PROG is pressed, the program is stored and irrigation will be performed according to this program.
If MENU is pressed, the program is deleted and the speed is the same for the entire irrigation lane.
