Helps to know which game as it could be all-the-above or worse.

Try the the topic search function again for a bit longer than 60 seconds.
Wealth of info on pinball maintenance and topics on your particular game. Congrats and good luck!

First thing you should do is check all the hardware above and below the playfield to see if anything is loose, the quality control from some of the manufacturers has gone down hill.

Looks like Munsters.

Don't under any circumstances consider this on Munsters.

Study more. Learn more. Ask questions here. And learn to search. There must be a lot of threads on what to do or don't do to your new pinball machine.

LTG : )

If you have a Stern, turn your trough kick out power down to 180 or lower, this will prevent clearcoat chipping/excessive wear in that area. Should be under game adjustments menu.

Clear coat???

Dude play your game, use PinGuy app to make sure you’re at ~6.5 degrees and level

Just do a general inspection; make sure nothing has vibrated loose and ensure all connectors are fully seated, look for any wiring that might be subject to getting caught in a mech., rubbing against something, or being pinched, clean both sides of the glass, level the machine (place level on center of playfield, not glass or cabinet), use >= 91% IPA or denatured ethanol to clean the oil off pinballs, ensure all zip-ties and other shipping fasteners/materials are removed from playfield objects, and put everything together as per the setup instructions.

As for initial adjustments, I’d leave the game and feature adjustments alone initially; the one thing I would definitely do is to reduce the eject power down to 180 or less (175 works for me) and turn the slingshot power down to about 18 (a reasonable starting point to minimize airballs shooting into the outlanes - you can tweak up or down from here to maximize action/minimize airballs once you play). After playing a few games you will get a good idea about adjusting the power of other mechs, especially VUKs. I also like to dial back the GI and insert intensity a little for enhanced contrast and “mood”, depending on the game.

As for waxing, it’s a controversial subject. Personally I don’t usually bother, as I set my games up to play fairly fast anyway, and given that I am meticulous about replacing balls, deteriorating rubber, and keeping playfields clean, I don’t feel the tedium of the additional step of properly doing a wax job is worth the effort in my situation where games only get played a handful of times per week on average. For a new pin, you might just give the playfield a quick blast or two of canned air to knock off any residual factory/shipping dust and displace any lingering scraps of packing material/random flotsam that might be hanging out.

That’s about it; now play the hell out of it and tweak the settings as you go to match your preferences.

After buying your first pin the next step is to start researching which pin will be your 2nd.

Ok I’ll tell him, clean your balls. Before hitting start.

Sell it for a profit. You will fit right in with 40% of pinside.

Kidding aside. Congratulations!

Call me a weirdo, but maybe press the start button and begin flipping?

No. Don't launch any balls, that will wear the shooter lane!

Step by step:
1) Open box
2) install legs
3) PLAY IT

Congratulations!

Have fun!

Play it for a week then come back with questions.

Welcome to the addiction.

Also... if you have kids and they are little, keep the box a few weeks. I cut out a door and a window on mY NIB box and the kids played with it for months....

Do NOT google "munsters pinball mods". Back AWAY. You been WARNED!
...I guess it's cold rhinoceros sandwiches again tonight...

If you are someone who would worry about playfield/shooter lane wear, install Cliffys. If not, immediately hit the start button. That said, many people suggest replacing the factory balls with better ones first.

Go to Rec.games.pinball and skip the pinside insanity.

Yes, with its 1 post per month, a lively bunch over there!

Coil stops, not sure if Stern upped the quality, but you may need yo change them. History of breaking in recent games.

Set it up and play it. If something falls off or does not work right, fix it.

I have yet to have a coil stop to fail. Probably another issue blown out of proportion.

Yes, blown out of proportion. I just had the left flipper coil stop fail on my JPLE after 813 games and a couple years. You know when they fail when the flipper feels kindly squishy and less snappy. The nub was loose and wobbly when removed. Coil stops are a couple bucks each, just pick up a couple on your next parts order.

Newer games tend to be super bouncy. As the rubber wears and it gets dirtier it will slow things down.

Unpack overpriced pinball machine and set aside. Clean up box and put a bow on it. Best X-mas present you will ever give your kids.
