One of the easier wpc games to tear down.
The battlefield comes off by unplugging the connectors, removing the thumb screw, and the its 4(?) screws on the hing bracket.
As doot said the wire forms come off fairly easy. And with them and the mini pf off you can get to most of the pf to clean and wax
The only difficulty I ran into the first time I tore mine apart were the divertor set screws (2 per) were held in with lock tight. The left one especially is in tight quarters under the pf - I repositioned lots of stuff around the area to make room to get my soldering iron in and Allen wrench.
