Removal and replacement strategy
Detailed steps and images showing part removal are included here. Replacement is
generally the reverse of removal. Occasionally, notes are included to provide directions for
difficult or critical replacement procedures.

Remove the power cord before attempting to service the product. If this warning is not
followed, severe injury can result as well as damage to the device. Certain functional checks

Sheet metal and plastic edges in the product can be sharp. Use caution when working on the

Some parts are sensitive to electrostatic discharge (ESD). Always perform service work at an
ESD-protected workstation.
To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
