Where in the rules is the pneumatic manual referenced? It seems to be more guidance than a rule. If it going to be taken as rule then it needs to be incorporated into the rules at least by reference so team know they are a rule.

R81 only says stored pressure needs the be below 120 PSI.
The Robot inspection checklist under power on checks specifies the compressor turns at about 120 PSI.
The Q&A Q459 specifically allows pressure switches to be calibrated if intended to be so by the manufacture.
All of this seems to be in conflict with pneumatic manual.

Using cheap non calibrated gauges to verify pressure settings, particularly safeties is a separate thread.
