About this task

In this procedure, there are two types of actions. For the Lower Base Side cover, you remove one or both of them. However, for the Upper Bellows, you fasten it in an up position.

The Upper Bellows, an accordion style cover, can be positioned up or down depending on the type of servicing needed. The Lower Base Side Cover is a solid single cover that runs the length of the lower chassis from the front caster assembly to the rear caster assembly on each side.
