4114 MaintenanceThe NORAC Spray Height Control system requires very little maintenance, but there are a fewprocedures that will ensure the system continues to work correctly for many years.Before each day: It is highly recommended that the sprayer friction pads are greased. To ensure optimumperformance this should be done daily. This will ensure the boom is pivotingseparately from the sprayer. It is very important to keep the friction pads greased onActive Roll™ systems. Ensure the height sensor breakaway brackets are functioning correctly. Apply grease to themoving parts if necessary, to ensure they return to center after a break-away occurs. Ensure there is a clean, dry foam disc inserted in each sensor. If it is clogged with dust orother debris, clean it as described below.At the end of the season: Replace the oil filter in the NORAC hydraulic manifold annually (NORAC P/N 106285).Cleaning Ultrasonic Height Sensors: Remove the foam disc from the sensor and wash it with clean water. Squeeze out excesswater and allow the foam disc to dry. The sensor can be used if the foam is wet, howeveryou may not get a valid height reading until it is completely dry. If the transducer inside the sensor is also dirty, wash it using clean water. Remove thesensor from the bracket and rinse debris from the transducer by pouring wateracross the face of the sensor. Do not submerge or pressure-wash the sensor. Asoft bristle brush can also be used to gently clean the transducer if water alone is notsufficient. Use caution not to scratch or tear the transducer as it is fragile. The sensorshould be left to dry with the transducer facing downwards. The sensor can be used if it iswet, however you may not get a valid height reading until it is completely dry. Leaving thecontrol system powered on with the sensor connected and facing down will speed theprocess of drying the sensor. Chemicals or compressed air should never be used to clean the sensor.
