1. Enter the rewind speed on the computer using the arrow keys.
2. Select the gear according to the table below. (Table is also in the machine cabinet)
1. For pre-irrigation, press "PRE" (highlighted in display). For post-irrigation, press "POST"
(highlighted in display).
2. Connect the feed hose.
3. Press "START".
4. Open the hydrant and start the water supply pump. The water must not be fed too quickly
into the machine to prevent air in the machine, hose and pipe. This can cause pressure
surge and kickback in the system.
WARNING:
• If the hose is in tension when uncoupling, the drum can run back with great
force.
• All other adjustments to the machine, gun trailer and gun should only be made
when the machine is not in operation.
Automatic and manual stop
Rewind stops automatically when the gun trailer is wound back into the machine, thereby
aff ecting the stop bracket. The machine stops due to either overpressure or underpressure.
The machine can also be stopped either at the pump or by pressing "STOP" on the computer.
Emergency stop and safety stop
The safety cable ensures that the machine will stop in case of computer failure.
The machine is equipped with a rewind error bracket that stops rewind if the hose guide
should come out of alignment, causing the hose to tangle. The rewind error bracket will
activate the stop bracket when the reel comes off the edge of the drum.
REMEMBER
when starting for the fi rst time, to check that the rewind error bracket and cable
are adjusted correctly.
Gun trailer and hose guide
The gun trailer can be adjusted with diff erent track widths. This is done by loosening the
locking bolts on the chassis and extending the legs to the desired track width.
If the gun trailer does not follow the same track during rewind as during unwind, loosen the
centre bolt on the steering wheel and move the wheel axle back and forth on one side by
turning the steering wheel.
The hose guide ensures that the hose is wound properly on the drum. If the hose does not
wind properly on the drum, the hose guide should be adjusted. The hose must be unwound
until there are two to three turns left on the drum. Remove the hose guide chains and adjust
the hose guide so the hose passing through the hose guide is against the hose already on the
drum. (Contact the service department at Fasterholt Maskinfabrik A/S)
