Is there a maintenance kit for Generac Model 4746 generator?  I want
to service the unit myself.

Hello Stucpa-ga,

In speaking with the comapny, there is not an available maintainance
kit. They reccomend that you take it to an authorized dealer in your
area, as not to void the warranty if you still are currently protected
by it. Also, they contract with businesses to provide maintance, so
that it all meets Generac standards, which is another reason the
maintainance kit is not available.

Here is a dealer locator:

And a parts locator:

A spec sheet:

Which I got from here:
