Generator/Electricity:

Wendy

Hobbs Meter: 2996.6 hrs

Voltage: 119 VAC

Frequency: 60 Hz

Oil Level: full

Notes/Comments:
Don came and installed the new fuel filter today and started Wendy. We
changed the oil and filter and drained the water this afternoon. We are
running off of the on-board fuel tank. We will refill from the yellow
fuel can. We will not run from the diesel drum until the filter is
changed. Don requested the filter number so that he could get a
replacement. The fuel filter is a Petro Clear from Champion
Laboratories and the part number is 40830 PA-DV.

How many hours per day should Wendy be run? Assume we will need to run
it overnight and at least part of the day.
