Adjustable POA Interrupter

Tools Required:

* Allen Wrench: 5/64” and 3/32”

* Nut Drivers: 1/4” , 5/16” and 11/32”

* Phillips Head Screwdriver

* Digital Level – highly recommended.

* Holder for screws / nuts.

Steps To Remove the Upper Playfield:

1) Below the playfield, unplug (1) one plug to Metal

Bridge Ramp #23.

2) Below the playfield, unplug (3) three plugs to Mini

Playfield Assembly #28 Path of Adventure.

3) Pull out the playfield.

4) Remove the three nut screws on #23 Metal Bridge

Ramp. Set this aside. Note that these three screws are

longer than the others.

5) Remove the two screws holding #32 Straight Metal

Ramp. Set this aside.

6) Remove Wire Ramp Bottom #35 by removing the nut

on the slingshot. Set this aside.

7) Remove the metal shoot #33 by removing the screw two screw nuts. Note that it maybe

necessary to remove or reposiVon the plasVc underneath to get to the lower screw. Set this

aside.

8) Loosen the Allen setscrew at the back / top of the Upper Playfield. Be careful not to loosen it

so far that the setscrew falls out.

9) Remove the two nut screws holding the boTom bracket of the upper playfield.

10) At this point, it should be possible to remove the Upper Playfield by pulling it back off of the

motor shaft. Be careful that the three wire cables pull out through the hole to below the

playfield.

11) Loosen the Allen setscrew holding the flag to the motor shaft being careful to not let this

setscrew fall out of the flag. Slide the flag off of the motor shaft.

Installation of the Replacement Flag

12) You will have received several different length

flags with your kit. To determine which flag is

likely to fit, set the flags one-by-one over your

metal flag. Select the one that appears to be the

closest fit. The one shown in this photo appears

to be just a little bit too short.

13) After selecting the flag, insert the nut into the fitted hole in the

flag. It maybe helpful to screw this nut part way into the Allen

setscrew to help insert it. Note that the nut must be in and flat for it to thread properly in the

following step.

I used the tool to get it close. After tightening down the flag onto the hub, I put the POA on and tightened it down, and attached the bottom bracket to the playfield (a must). Check to insure that the Allen screws are tight – all three (two on the flag on the one on the POA). Don’t over tighten the 3D printed screws.

I left all the ramps off on the left of the POA and the top one. I tilt the top one up, out of the way leaving the center / bottom screw attached, but that is scary as it would get crushed in lower the playfield and sliding it back. So people should likely remove the back ramp too.

Buying a nice digital level makes this very easy, here is the one I recommend you buy.

Playfield has to be pushed back into the play position. This can not be done accurately with the playfield pulled out.

I went into the service menu, then Tests, POA test (I think #15) and let it do its thing. Next step in that test is to go to the full left / right / center. I let it go left and stopped it using the door button. Recorded the value. Tilted it right and stopped it using the coin door button. Measured again.

If it tilts too far left, I then tilted it right. That is important because the flag has to be pushed down a little. If it is left, it could be pushed through the opto.

Pull the playfield out.

If it tilts too far left, use the Service Menu to tilt right and stop it. Loosen the flag Allen screw just a little and try to barely push down on it. When it moves, tighten. Push the playfield back in and repeat the steps until left and right are approximately equal. Don’t try to get it perfect.

If it tilts too far right, do the above steps, but tilt the POA to the left, pull the playfield out, loosen the flag screw and pull up gently on the flag until it moves. Tighten the screw, push the playfield back in and test.

Make sure the POA does not hit anything moving left or right and the wires to the POA cannot restrict its movement.
