10-1 Inspections
Daily or periodic inspections are required in order to maintain the FQM1 in
peak operating condition.

10-1-1 Inspection Points
Although the major components in the FQM1 have an extremely long life time,
they can deteriorate under improper environmental conditions. Periodic
inspections are thus required to ensure that the required condition is being
maintained.
