Where is the chaincase inspection/fill plug on this machine and is there one on each side?
You only have one chaincase and it's in the center of the frame and your fill/inspection plug is front center of the lower frame. Raise the arms and support and you will be able to find it.
This is what the chaincase looks like, viewing from the rear. #12 is the drain/ fill plug. If you need to inspect chains or brakes you will need to remove one of the top case covers.
