Went to change the break in oil in my 5425. The drain plug has a square hole, I found that the drive part of a 3/8 socket wrench seemed to fit the hole but it's on so tight I couldn't budge it. Is there a special tool to get that thing off?
First time removing the plug there might be some paint in the threads and that can make it a bit stubborn -- might try a short piece of pipe on the socket wrench handle; cheater bar.
