game cabinet. While supporting the backbox, cut the
strap holding the parts together and set the backbox
aside.
16. Locate the factory keys, either on the shooter rod or
taped to the playfield glass.
17. Using the diagonal cutters, cut the tie-wrap securing
the keys if required. One set of keys is for the front coin
door, the other set of keys is for accessing components
in the backbox.
18. Using the backbox key, locate the backbox lock on top
of the backbox and unlock the lock.
19. Gently remove the backglass frame assembly by lifting
the backglass frame vertically and pulling away from
the backbox.

glass removed, over the top of the cabinet and align the
holes.
21. Install the two 3/8-16 x 3.00" bolts in the (2) backbox
holes and tighten with the 3/8" wrench.
22. Open the front coin door.
23. Reach into the game and remove the retaining clip at
the rear of the cash box.

backbox bolts from the cash box.
26. Replace the cash box lid and retaining clip for future
use.
27. Store the backbox keys on the metal hook located in
the coin door.

31. Reach inside the cabinet and lift the two latches holding
the playfield in place. If pinballs were already installed
into the lower ball trough, remove them before lifting the
playfield.
32. Grasp the lower arch between the flippers, and firmly
but gently pull directly up to raise the playfield 8 to 12
inches.
33. While holding the playfield up, pull the playfield about
one foot towards you.
34. Pivot the playfield vertically and rest it against the
backbox.
35. Visually inspect all cabinet cables and connector
terminations; ensure no wires or cables are pinched and
that cable harnesses are not pulled tight.
36. Locate the plumb bob in the parts bag in the cash box
37. Slide plumb bob onto the hanger wire. Note: the vertical
position of the plumb bob affects tilt sensitivity - higher
makes the game more sensitive to tilting.
38. Tighten the thumb screw finger-tight.
39. Install the correct number of pinballs. Refer to the decal
on the lock down assembly for the correct number of
pinballs.
CAUTION: PLAYFIELD GLASS IS MADE FROM HIGH-STRENGTH
TEMPERED GLASS. TEMPERED GLASS IS SENSITIVE TO EXTREME
TEMPERATURE SHIFTS AND CORNER NICKS, WHICH CAN CAUSE
THE GLASS TO FAIL CATASTROPHICALLY. TAKE CARE TO STORE THE
GLASS ON A SOFT, ROOM-TEMPERATURE SURFACE AND PREVENT
THE CORNERS FROM BEING DAMAGED.
