Replace the pump cylinder gasket and make sure that it fits tightly around the top of the pump cylinder.

How do I remove the battery from my Black and Decker CMM1200 lawn mower?

Thanks

ANSWER : I have an older model CMM625, but I suspect that the method is similar. There should be some screws that hold down the upper deck to the lower one. On mine the screws are in the back and there are tabs in the front that holds the upper deck to the lower. Once this is removed, you can see the battery and it’s connections and hold down bracketry.
