Raising the playfield

Steps

• Remove the glass and every ball first.
• Lift from the front edge, pulling the shooter knob out slightly so the playfield clears it.
• On some older games, first remove the side screws or side latches, or pull forward the long latch bar under the front of the playfield; you may also need to ease it toward you roughly an inch so its rear edge clears.
• Rest an unhinged playfield on the hinged prop bar on the right side of the cabinet, or slide it forward on the side rails and lean it back against the backbox for more room. Newer games have hinged playfields.
• If anything catches, stop and look rather than forcing it.
