4.0. MAINTENANCE
Mid-Tech recommends the following maintenance to keep your TASC system operating at peak efficiency.
4.1. FLUSHING AND CLEANING
NOTE: It is important to keep your chemical applicator clean. Chemicals are becoming more potent and environmental
considerations are becoming more demanding. Keeping the equipment clean also makes it easier to maintain the vehicle
and extends its working life.
Always refer to the chemical manufacturer's directions regarding cleaning and flushing.
As a general rule MID-TECH recommends the following:
A. Do not leave chemical in the injection pump or application lines overnight. The system should be flushed and cleaned
at the end of each day's operation. Some chemicals actually bind to the walls of the containers and lines. The longer the
chemical is in contact, the greater the possibility that this will occur. Bound chemical has been known to release during
subsequent spraying operations with detrimental affects on the crop being sprayed. Flushing and cleaning so that
chemical is not left in the sprayer for long periods of time will make this less of a concern.
B. All of the injection pumps should be flushed daily, regardless of use. Running the pumps frequently helps to keep the
pumps in good working order. Unless the injection line from the pump has a positive shut off valve, some of the
chemical applied that day may have migrated up the injection line to the pump. Flushing all the pumps helps guard
against contamination.
4.2. INJECTION PUMPS
For the best tube and pump life, clean and lubricate the flexible tubing in the injection pumps prior to each day’s
operation (use only the Tube Lube from your supplier).
At the end of each day’s use, disconnect the line from the chemical tank (or turn off the valve at the outlet of the
chemical tank) and remove the tube from the pump housing to prevent it from developing a hard spot under the roller.
This is particularly important in cold weather or if the pump will not be operated again the next day.
4.2.1. WEEKLY PUMP MAINTENANCE
Check the flexible pump tubing carefully for wear each week during frequent operations. Check for cracking, side splits,
or other signs of material fatigue. If any signs of deterioration are seen, the tubing must be replaced immediately
(replacement tubing kits are available from your MID-TECH dealer).
CAUTION: BE SURE THE CHEMICAL LINES ARE
DISCONNECTED OR TANK VALVES ARE “OFF”, SO
THAT LIQUIDS CANNOT DRAIN OR SIPHON INTO
THE MAIN BOOM SUPPLY LINE WHEN THE TUBES
ARE REMOVED FROM THE INJECTION PUMP.
WARNING: Failure to follow the manufacturer's recommended cleaning and
flushing procedures may result in chemical damage to crops receiving later
treatment. Of course, all flushed liquid should be collected and disposed of in
accordance with the applicable federal, state and local regulations for your area.
