Maintenance tolerance shall not exceed what value on full or light load?

Maintenance tolerance is the allowable deviation from the nominal value during checks. Here, the limit is a symmetric ±2% that applies whether the system is at full load or light load. A wider tolerance like ±4% would let more error slip in, which isn’t allowed by the requirement. An asymmetrical tolerance (+4% / −2%) or a rule that changes with load (4% full, 2% light) would violate the instruction that the same limit applies to both conditions. So the correct interpretation is a fixed, symmetric ±2% tolerance for both full and light load.
