When equipment is removed, first confirm that measures are in
place to prevent dropping of work pieces and run-away of
equipment, etc. Then cut the supply pressure and power, and
exhaust all compressed air from the system using its residual
pressure release function.
Valves should be switched at least once every 30 days to pre-
vent malfunction. (Use caution regarding the air supply.)
When the manual override is operated, connected equipment
will be actuated. Confirm safety before operating.
