Tilting Rear Chassis
Some repair procedures require you to tilt the Rear Chassis. Other repair procedures may require you to
pivot the Rear Chassis upward or downward or remove it altogether; these procedures are discussed in
corresponding sections.
CAUTION: Tilting or pivoting of the Rear Chassis involves a scissor-like movement between the Rear and Front
Chassis. Take care not to injure your fingers or shear the wires.
To tilt the Rear Chassis:
1 Open the HeartStart XL+ Case. See “Opening the Case” on page 87.
2 Position the box display side down.
3 Remove the T10 screws
➋, ➌, ➍, ➎, and ➏, see Figure 52.
4 Loosen slightly but not remove the screws
➊ and ➐.
5 Tilt the Rear Chassis up around the axis formed by the screws
➊ and ➐.
Do not stress wires and connectors by turning too far.
6 While in the tilted position, tighten the screws
➊ and ➐ to prevent the Rear Chassis from accidental
movements.
