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 free -
ly. (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 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-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 mo-
tor).
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 ap-
prox. 200 degrees. This means that the gun operates over an
angle of 200 degrees.
