MACHINE ASSEMBLY
The “Stacker Giant” is shipped in three main sections, the Machine Main Cabinet,
the Light Box Header, and the Control Panel. The Machine Main Cabinet contains
the prize arms, LED playfield display, and capsule dispenser. The Light Box Header is
the acrylic roof of the cabinet which contains three fluorescent lamps and prize display
down lamps. The Control Panel is where the player controls, coin mechanisms,
capsule dispenser pipe, and service controls are. The game should not be shipped fully
assembled as this could cause damage to all machine sections.
Position the Machine Main Cabinet nearby to its final location. The cabinet has six
heavy duty castors to allow easy positioning of the game. Clear the roof top of the
cabinet from any obstructions.
Using at least two persons, lift and position the Light Box Header on the top of the
Machine Main Cabinet, placing the down lamps in the Light Box Header right on
each lamp opening at the top of the Machine Main Cabinet. Using the four JP M5
x 30mm, tighten the Light Box Header to the Machine Main Cabinet from the
under side of the Cabinet’s roof. Feed the cables from the Header to the connectors
that come out from the opening at the right back corner of the Cabinet. (Refer to the
picture on next page)
Place the two header side plates on the right and left side of the Light Box Header.
Slid the horizontal part into the gap in the upper part of the Machine Main Cabinet
and tighten them to the Header using the four Hexagonal Socket Head M5 x
15mm bolts and to the Machine Main Cabinet using the two JP M6 x 30mm
bolts.(Refer to the picture on next page)
Place the two pairs of header back plates on the top of the Machine Main Cabinet,
behind the Light Box Header. Tighten the plates using the two M6 x 15mm bolts
and the four 4 x 15mm self taping screws. (Refer to the picture on next page)
Position the Control Panel assy in front of the Machine Main Cabinet, right in the
middle part of the cabinet. Make sure that the capsule dispenser’s ball feeder in the
Machine Main Cabinet is plugged in to the pipe in the Control Panel. Tighten the
Control Panel to the Machine Main Cabinet using the four Wing M5 x 15mm
bolts (left and right side of Control Panel)and two Hexagonal Head M6 x 15mm
bolts (lower part of Control Panel). Feed the cables from the Control Panel
through the middle part of the Machine Main Cabinet. Mate all the connectors
together; they are keyed to prevent incorrect connection. (Refer to the picture on
next page)

redemption game. “Stacker Giant” features an impressive giant cabinet with heavy duty

to the major prize level.
