Answers:    As the previous answer stated waiting for a period of dormancy is a dutiful idea surrounded by general, but for maples winter isn't the best time to prune unless you beyond doubt have to. If you prune a maple within the winter the cuts won't have be compartmentalized by the time the sap starts running in the Spring, substance you'll have sap leak from each and every cut (messy, visually repulsive, and potentially a lure for insects that could harm the tree). Wait til mid to deferred summer to prune, that way the sap won't be running, and near will be a period of growth during the trickle that will help to trademark the wounds off (provided you pruned correctly). Check out tlcfortrees.info for the proper pruning technique and for information on topping (sounds like what you are doing)
