Power off machine, unplug the main power cord.
Set playfield in service position.
Each pop bumper has 4 screws, (one in each corner)
- Start by taking one screw out of each pop bumper and measure the length. Metric 16mm or Imperial #8-5/8.
If length is correct on the first screw, all screws will probably be correct length.
if you see a washer - remove them all, and measure the length, if correct length, reinsert screws but without the washer.
- If you don't have the correct length, please contact support. with topic #004 and we will send you new correct screws.
