READ THIS MANUAL
BEFORE USING YOUR IRRIGATOR !!
Operating instructions
for Fasterholt FM 4550
Your new Fasterholt Irrigator is a Danish built machine, but even the
best machines only deliver top results when they are properly used
and maintained.
To ensure that the machine complies with the EU Machinery
Directive, only original spare parts may be used. Otherwise,
compliance will be lost and safety will be entirely at your own risk.
The irrigator is intended for irrigation with clean water from a drilled
well or a watercourse.
1. Safety instructions/warnings !!
―It is forbidden to stand on the machine during
irrigation and transport
(risk of fatal injury).
―The guards are fitted for your own safety - please leave
them in place
―Remember to tighten the wheel bolts
―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.
―If a rear wheel is removed, THE MACHINE MUST BE
JACKED UP AND VERY STABLE, because if it overturns,
it will fall completely on its side.
WARNING !!
―To perform an EMERGENCY STOP, pull the cable for the mi-
swinding bar or press STOP on the COMPUTER
―V-belts may only be tted after the machine has been unwound
for the rst time. (only the rst time the machine is used for
irrigation.)
―The gun must face out to the side when unwinding the ma-
chine.
―STAND ASIDE when the gun is operating.
―WARNING against contact with overhead power lines with the
machine or water jet. Avoid irrigation on or near power lines.
―During transport on uneven roads/elds, move VERY carefully
according to the conditions.
―Max. transport speed with water in the hose is 15 km/h.
―When parking the machine, use the wheel chocks mounted by
the rear wheels
―DANGER !! Avoid welding in the paint layer! Before welding,
remove all paint from the welding area
―Avoid inhalation of grinding dust.
―Hydraulic oil can be harmful to health:
―Skin contact may cause allergies
―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 separa-
tion.
―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. NEVER place the battery in a sealed container while
charging. During winter, the battery must be removed and
stored in a dry place indoors in a fully charged state.
―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 immediately with water. If acid comes into contact with
eyes, rinse 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 imme-
diately.
―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 collection site.
―Batteries, hoses, tyres and other parts of the irrigation machine

Starting your irrigator
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. Recommenda-
tion: Remove the drum belt from the belt tensioner before unwind-
ing. When the machine is at the target, reattach the belt to the
belt tensioner before disconnecting the machine. 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 pawl.
REMEMBER !! When starting the machine on falling ground, you
must be VERY careful not to disconnect the tractor from the
machine until the irrigator has been put into gear, otherwise the
machine may run away. Attach the charge hose to the hydrant, if
necessary turn on the hydrant.
During irrigation
Safety stop
Stop pawl
Secure the hose chains with the long ground spikes. Lower the drawbar
over the hose and release the safety stop so the hose reel runs on the
hose.
During transport
Unwind the machine with the brake applied suciently 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.
The machine should be unwound completely at least every 3rd time.
Before starting to unwind the machine, reset the COMPUTER. 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).
Winding speed: Recommended max. 5 km/h
Preparing the machine for irrigation
ALWAYS REMEMBER that the TOGGLE SWITCH must be pressed down
during operation, otherwise the machine will not move.
Engage the pawl.
Tighten the V-belt (belt tension lever) so the spring is fully com-
pressed around the spacer pipe.

Release the brake lever completely. Remember also to release the
electric brake (Remember that the electric brake connector must
be removed from the tractor).
Before connecting the tractor to the rear of the machine, disen-
gage the gear and raise the drawbar at the front before starting
the machine.
Remember to close the decoupling valve (lever "1" must be
pulled out.)
REMEMBER to connect machines with coupling levers (lever "2"
pushed in).
Attach the charge hose to the hydrant. Then open the hydrant,
start the pump and irrigation can begin. The speed you want
to move at is set in Program Rain. You do not have to select a
gear as this is stepless speed regulation controlled by Program
Rain. On some other models, gears are selected according to the
machine instructions.
When starting irrigation, see the section that refers to the operat-
ing instructions for PROGRAM RAIN.
Preparing the machine after irrigation
After irrigation, tighten the brake and loosen the V-belt. Then 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.
Maintenance
1x per week:
Check that no water is entering the oil on the rear axle assembly.
Lubricate the steering, roller chain for hose guides, roller chain for forward trac-
tion, cross track shaft for hose guide with water-repellent grease.
Check tyre pressure:
Rear wheels 2.9 bar/ 42.06 psi
Front wheels 2.9 bar/ 42.06 psi
Check that front and rear drawbars line up. If not, turn the lever on the side of the
machine by the front control cylinder. This is how to adjust the drawbars so they
line up. Turn the lever back again.
Clean the lter at the turbine outlet if required.
Check that the hose is positioned neatly.
Remember to check the guide pins in the hose guides regularly.
Remember to tighten the wheel bolts regularly.
NOTE:
The battery should be charged once a month during the season to maintain full
power and extend its useful life.
Preparation for winter
Drain water from the machine:
The machine is easily emptied with air (only done with special compressors).
Contact Fasterholt Maskinfabrik A/S if necessary.

REMEMBER !! Before unwinding the hose:
Open the lter coupling.
Open the valve in the base of the turbine.
On machines with high pressure stops, press 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/gears 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.
(see page 9)
Guide pins should be replaced every year.
Faults on the Irrigator
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. (can be seen on the display
under menu 3.)
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.
b. The guide pin is worn and needs to be replaced.
c. The V-belts are too slack or excessively worn: To tighten the belt,
move the hole plate at the end of the cable. If it cannot be moved any
further, the cable needs to be shortened.
3. Forced steering is not lined up and seems springy.
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).
Setting the gun
The operating pressure of the gun should be 4.5 - 5.0 bar depending on the
type of gun and the water volume. For high water volumes, the pressure
should be higher.
The best spreading width is achieved at a sector angle of approx. 200 de-
grees. This means that the gun operates over an angle of 200 degrees.

1. Select and install the nozzle size that best suits your application. Performance data for the dierent sizes are shown in the table
below.
2. Adjust the stop on the part circle to obtain the desired irrigation angle.
3. There is a grease tting which should be checked once a week for relling.
ADJUSTMENT
The only thing you can adjust is the counterweight on the drive arm. By moving the
counterweight forward, the gun will slowly irrigate from side to side. If you move the
counterweight back, the gun will irrigate quickly. If it does not irrigate quickly enough, you
can remove the brake springs (no. 778474) in pairs (contact the service department).
WARNING: DO NOT ADJUST WHEN THE GUN IS IRRIGATING !!

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 con-
stant "8" can be changed individually for pre- and post-irrigation. (See constants on page 16). 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.

18
There are a variety of constants that can be modied by the user.
These constants will be stored for many years, even if the battery is removed.
Programming procedure:
Adjust the speed to 11.1 m/h to access the constants.
Press the PROG key 3 times in quick succession to access and change the constants.
Press the PROG key again to count forward to the constant you wish to change.
Press "+" and "-" to adjust the value of the constant.
Press the MENU key to save the change and the display will return to normal.
If the MENU key is not pressed, the display will return to normal after 1 minute and the change will not be saved.

Troubleshooting:
?
The turbine does not start when the START key is pressed.
Answer:
The magnet at the stop sensor is not in position or the sensor or sensor cable is damaged.
Stop sensor: The mark must be on when the magnet is in position and o when the magnet is removed. See Menu 3.
A damaged cable can be assembled in an epoxy moulded assembly or with shrinkable tubing and glue.
However, since the sensors are more sensitive than telephone cables in the ground, cable assembly must be seen as an emergency
solution.
If a pressostat is installed, the water must be pressurized. The mark must be on when there is pressure.
?
No numbers in the display.
Answer:
Battery disconnected. Fuse inside the box may have blown. The fuse will blow if the battery is wrongly connected.
An additional fuse is available from the factory on a single fuse terminal on the circuit board.
Fuse 5A. Battery voltage 12V. See Menu 2.
?
Clock is set to 00:00
Answer:
If the power is interrupted, the clock is reset. The end time is then the number of hours and minutes until irrigation is complete.
See page 15 for setting the clock.
?
The number of metres is not counted correctly and the speed is not correct.
Answer:
If the speed is measured with a roller running on the hose, check whether the roller is running smoothly or if it is not installed prop-
erly on the hose. You will also need to check that the roller sensor with cable is functioning properly. See Menu 3 Speed sensor.
The 2 marks must light up in the following order from the right during unwinding: The rst one turns on, then the second one
turns on, the rst one turns o, then the second one turns o. During rewind, this happens in reverse order.
?
Only half or perhaps 2/3 of the actual length has been counted.
Answer:
The stop bracket with magnet for the stop sensor may have jumped, so the magnet has been removed temporarily from the stop
sensor. This will reset the counter. Or a hose turn has been so loose that it has impacted the miswinding bracket.
This is usually the same as the impact on the stop bracket and has the same result.
Even if the metres are not saved in the memory, irrigation will still continue at the selected speed and the machine will stop as
normal. However, there will be deviations if the speed is measured on a gear disc and the calculation is based on formulas entered
in MACHINE DATA. This is because the electronics do not know which hose layer the machine is running on. Finally, the metres can
be entered manually.
See page 21. CONSTANT no. 7
