Start-up
Important before starting the machine!
If exposed to sunlight, the hose may become hot. Check that the hose is not above 30 degrees before starting. If the hose is too hot, cool it
first by flushing water through it.
1. Engage the coupling lever (Fig. 4, Pos 2)
2. Select the gear from the table located inside the cover (Fig. 4, Pos 3).
3. Enter the rewind speed on the computer using the arrow keys (see section under Rainfall.)
4. For pre-irrigation, press
Pre
(highlighted in display.)
5. For post-irrigation, press Post (highlighted in display.)
6. Connect the feed hose.
7. Press start.
8. Open the hydrant and start the water supply pump.
Note:
The pump must be started within the supervision time (factory set at 20 minutes).
See also “PR 10-12” User Instruction for further programming options.
Warning:
It is forbidden to climb on or under the machine during operation.
Rainfall
Once the rewind speed, nozzle type, nozzle size and nozzle pressure are known, the rainfall can be read in the tables. The nozzle pressure
can be read on the gun manometer. The table shows the maximum effective spreading widths in calm weather. In windy conditions, it will
drop by about 10%.
Setting the gun:
The operating pressure of the gun should be 3.5 - 4.5 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.
Rewind direction
Automatic stop
Rewind stops automatically when the gun trailer is wound back into the machine and the stop buffer hits the hose guide. The machine is
fitted with high pressure or low pressure stops.
At high pressure stop, switch off the water supply to the machine and make sure that the pump either stops via a pressostat or can dispose
of water by other means.
At low pressure stop, open the butterfly valve to allow some water through, the pressure will drop and the pump will stop via a pressostat.
If high pressure or low pressure is changed, contact your Fasterholt dealer.
Stop buffer
Mount the stop buffer on the hose using two hose clamps (Fig. 4, Pos 6.)
