The hydraulic pressure range that is used for cautionary purposes is which?

• A. 1400-1600 psi
• B. 1200-1400 psi
• C. 1000-1200 psi
• D. 1600 psi

Answer: (B)

In hydraulic systems, the cautionary range is the band where the system is still functioning but operating near its limits, so you watch closely and be prepared to reduce stress or take preventive action. Typically, normal operation sits at lower pressures, while the maximum is at the high end of the spectrum. The 1200–1400 psi range sits clearly above normal operation and below the maximum, making it the standard cautionary zone. It signals that components are under more strain and you should monitor for signs of wear or performance changes, rather than pushing toward the limit. The other ranges either represent normal operating pressure (lower end) or values that approach or hit the maximum limit (upper end), which is why 1200–1400 psi is identified as the cautionary range.
