BE CAREFUL THAT WATER OR SEDIMENT IS NOT TRAPPED IN THE INJECTION PUMP, PAR-
TICULARLY IN COLD WEATHER, AS DAMAGE TO THE MECHANISM MAY OCCUR.
4.9.1 SEASONAL
Calibrate the pump at the start of each season.
4.9.2 PERIODIC
Check calibration whenever it is suspected the system accuracy has deteriorated.
4.10 WIRING HARNESS
Inspect the external cabling for abrasion, stretched or pinched wires. If such a condition is seen, reroute the cabling
and wrap it to protect it from further damage. If a broken wire is found, temporarily repair it by stripping the wire
back on either side of the break, twisting it together and soldering the connection (USE ONLY ROSIN CORE
SOLDER). The bare connection must be well insulated with heat shrinkable tubing or electrical tape.
MID-TECH strongly recommends replacement of damaged cables as soon as possible. Once a cable is damaged,
moisture and chemicals can work their way under the insulation and cause corrosion to the conductor. In the end,
continued problems will be experienced until the cable is replaced.
Periodically inspect the connectors on all cables. Use a non-lubricating spray solvent to clean connectors. Lubricat-
ing sprays leave a film which collects dirt and can eventually lead to connector failure. Clean connectors with a soft
swab, like a Q-TIP. Do not use abrasive materials to clean connector contacts.
Check all fuses and fuse holders for any signs of corrosion and clean as necessary. There are fuses on the power
connections at the battery, some boom control cables have a fuse for each boom section, and some of the newer
motorized boom valves have fuses in the connector cables.
