We don't have any units that see 100 hours/year, many with only exercise time on them. I bought my 4390 from one of our customers, it's 15 years old and has 480 hours on the clock and it came from a neighborhood with lots of outages. We also recommend service once a year due to the condensation in the oil and also most of our customers are not hands-on, we have some that lock out on an alarm and the homeowners call to request service and we find it hasn't run for 2 -3 months.
I run across this all the time.. The look on their faces when I tell them the generator hasn't been ready to run for 9 months! 🙂
A great reason to subscribe to the dealer monitored mobile fleet!
