4.0 MAINTENANCE
Maintenance is a matter of common sense. Here are a few tips.
4.1 FLUSHING AND CLEANING
It is important to keep the chemical applicator clean. Chemicals are becoming more and more potent and environ-
mental 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 manufac-
turer requires a triple rinsing, then all parts of the applicator that have come in contact with the chemical must be
triple rinsed with clear 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:
1. Do not leave chemical in injection or application lines overnight. The system should be flushed and
cleaned at the end of each day's operation. Some chemicals can bind to the walls of the containers and lines. The
longer the chemical is in contact, the greater the possibility this will occur. Bound chemical has been known to
release during subsequent application operations, seriously affecting the crop being treated. Flushing and cleaning so
that chemical is not left in the sprayer for long periods of time makes this less of a concern.
2. All injection pumps should be flushed daily, regardless of use. Exercising the pumps is good for them. It
helps to keep pumps in good working order. Also, unless the pump has a positive shut off valve, some of the chemi-
cal applied that day may migrate up the injection line. Flushing all the injection pumps helps guard against contami-
nation.
4.2 TASC CONTROL CONSOLE
The TASC console requires no maintenance other than general cleanliness and auditing the constants stored in
memory. The console can be kept clean by wiping with a damp cloth. Unused connectors should be covered with the
dust covers provided. The constants can be monitored by checking each of the calibration constants and each of the
desired application rates.
TASC uses non-volatile memory to store constants. It is unlikely there will be a need to reenter constants, however,
there have been rare cases of constants being changed as a result of random electrical interference. For this reason,
MIDWEST TECHNOLOGIES strongly recommends keeping a written record of the calibration constants. Check
daily, before commencing applications.
SOAP
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 for your area.
