The monthly and yearly lists are an average interval. In the case of
a dirty environment, service interval may need to be shortened.

flammable vapor being exposed to the atmosphere creating an ignition.
Do not operate any equipment that may create a spark during
maintenance.
WARNING:

death when handled incorrectly. Do not perform maintenance until power
has been disconnected from ignition transformer.
