4.0. MAINTENANCE
MIDWEST TECHNOLOGIES recommends the following maintenance to keep your control system operating at peak efficiency.
4.1. FLUSHING AND CLEANING
It is important to keep your chemical applicator clean. Chemicals are becoming more and more potent and environmental
considerations are becoming more demanding. Keeping the equipment clean also makes it easier to maintain the vehicle and
increases its working life.
Always refer to the chemical manufacturer's directions regarding cleaning and flushing. For example: If the manufacturer requires
a triple rinsing, then all parts of the applicator that have come in contact with the chemical should be triple rinsed with fresh water.
If the manufacturer requires rinsing with a special solution, then all parts of the applicator that have come in contact with the
chemical should be rinsed with the solution.
As a general rule, MIDWEST TECHNOLOGIES recommends the following. Do not leave chemical or chemical solutions in the
applicator overnight. The system should be cleaned at the end of each day's operation. Some chemicals will bind to the walls
of containers and hoses. The longer the chemical is in contact, the greater the possibility this will occur. Bound up chemical has
been known to release during subsequent spraying operations, seriously affecting the crop being treated. Flushing and cleaning
so that the chemical is not left in the applicator for long periods of time will make this less of a concern.
WARNING: Failure to follow the manufacturer's recommended cleaning and flushing procedures may result in chemical damage
to crops receiving later treatment. All flushed material must be collected and disposed of in accordance with the applicable federal,
state and local regulations in your area.
4.2. CONTROL CONSOLE
The control console requires no maintenance, other than cleanliness and auditing the constants stored in memory. The console
can be kept clean by wiping with a damp cloth and by covering unused connectors with the attached dust covers. The constants
can be monitored by checking each of the calibration numbers, and the desired application rate value (Refer to Section 2.0.,
Calibration and Set-Up.)
The control console uses a nonvolatile memory for storing the constants it needs to operate properly. It is unlikely there will be
a need to reenter the calibration constants. However, there have been rare cases of constants being distorted as a result of random
electromagnetic interference. For this reason, MIDWEST TECHNOLOGIES strongly recommends recording the current
calibration numbers in a convenient location and checking these calibrations daily, before operating the sprayer.
4.3. GROUND SPEED SENSOR
WHEEL SENSOR: Check the sensor daily for loose or bent fittings. Mud or trash build up can push the sensor out of alignment
or knock the magnets off. Repair or replace any damaged components immediately and calibrate the sensor (Refer to section 2.8.,
Distance Calibration).
RADAR SENSOR: Check the sensor daily to make sure the face of the sensor is relatively clean (no dirt build up) and that the
mounting bracket and hardware is tight and has not shifted in position. The sensor can be cleaned using a damp cloth. If it is
suspected or found that the radar sensor mounting position has shifted, the mounting bracket must be tightened and the sensor
must be calibrated. (Refer to Section 2.8., Distance Calibration)
WARNING: While inspecting and cleaning the radar speed sensor, take care not to look directly into the face of the unit.
The radar generates a low level microwave signal when it is operating and it may be dangerous to the eyes.
