REMEMBER !! Before unwinding the hose:
Open the filter 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 flow out freely. (Disconnect bat -
tery lead so stop valve does not close again.) Press stop
motor on Prog. key
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 filter 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-repel -
lent 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 filter 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 fits 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
degrees. This means that the gun operates over an angle of 200 degrees.
