Sensor Maintenance; Nozzle Maintenance - Croplands WEED-IT Quadro User Manual

5.1 Sensor maintenance

Regularly clean the windows of the sensors with a soft clean cloth.
Make sure you use a clean cloth; sand will scratch the sensor windows.
After system start-up any leaking sensors will be indicated by the system. A leakage error will
be displayed, including which sensor(s) is suffering from this issue. Possible causes:
Sensor housing (seal) damage.
Damaged breather plug, located behind the sensor connector.
Missing sensor cable. This cable must be connected to the sensor at all times, and the
orange seal in this connector must be intact.
If the sensor cable is removed, place a connector dust cap in the connector on the sensor.
Always return a leaking sensor to your Supplier/Dealer for further diagnosis.
If no replacement sensor is available, move a functioning sensor from the
outside of the boom to the position of the faulty sensor. In this way, you can
still spray a complete area (even though it is not as wide as you would like it to
be) and communication is not interrupted.
Make sure that the nozzle configuration is correct for this sensor (distance
and height). Also adjust the offset, because this changes if the sensor's
position on the boom is changed. Contact your supplier for support.

5.2 Nozzle maintenance

We recommend to use at least a 100 mesh pressure filter in your sprayer to
prevent solenoid valve clogging or damage due to particles.
Do not leave your sprayer with chemical in the spray line. Always rinse the
spray line and nozzles with clean water before storing the machine, even if
you will use it again the next day.
Regularly flush nozzles to make sure that they are not clogged. Refer to "Cleaning nozzles"
on page 28 for more information. Always replace faulty nozzles.
To replace a nozzle:
1. Twist the nozzle cap counter clockwise.
2. Push the nozzle and nozzle seal out of the nozzle cap. Undamaged nozzle caps may be
re-used.
3. Fit a new nozzle and nozzle seal into the cap.
4. Twist the cap, nozzle and seal back on clockwise.
