1.4 REPLACING THE PULSECODER
This section explains how to replace the Pulsecoder and motor cover,
assuming that the Pulsecoder has broken down and is in need of
immediate replacement.
When replacing the Pulsecoder and motor cover, be careful not to give
a shock to the Pulsecoder or motor, because they are precision devices
prone to a breakdown. Also keep them from dust and cutting chips.
