Preventative maintenance contract with company that installed unit is
$295 per year and calls for two annual visits to include oil change,
new oil filter, new air filter, change spark plugs, check battery and
charger, check output voltage, load test the unit, check connections,
and check operation of unit.
Problem is that it's like pulling teeth to get the technicians out
here and there are no other Kohler people in the area.
QUESTION: Can a general electrical contractor perform the duties
above, or does he need specialized training in Kohler home generators?
