2 Loosen the Cell Entrance and Exit Lens assembly screws a quarter turn.
To avoid damage to the Octopole from force applied while dismantling the
Octopole in the next procedure, loosen the Cell Exit Lens assembly screw
(Figure 84) and the Cell Entrance Lens assembly screw (Figure 85) a
quarter turn prior to disassembly.

NOTE
When cleaning the Reaction Cell assembly, lay out the dismantled components in the order
of their original configuration.
NOTE
Only loosen the Cell Entrance and Exit Lens assembly screw a quarter turn. Loosening the
screws more than that could cause the components to come apart and make the task more
difficult.
