The bottom thumbscrew on the front analyzer side plate should be
unfastened during normal use. It is only fastened during shipping. The top
thumbscrew on the front side plate should only be fastened if hydrogen or
other flammable or toxic substances are used for carrier gas, or during
CI operation.

In the next step, if you feel resistance, stop. Do not try to force the side plate
open. Verify that the MS is vented. Verify that both the front and rear side plate
screws are completely loose.
