When performing a daily inspection, what check must be completed?

• A. Check energy absorber temperature
• B. Cam index setting
• C. Test the hydraulic pump pressure
• D. Verify shuttle valve alignment

Answer: (B)

During a daily inspection, checking the cam index setting is essential because it establishes the reference position for the cam-driven control system. This setting ensures that timing and sequencing of the associated actuators and switches occur at the correct points in the cycle. If the cam index drifts, components can engage too early or too late, leading to improper operation or safety interlocks not working as designed. Energy absorber temperature, while important for overall system health, does not define the correct sequencing or timing during a daily check. Similarly, hydraulic pump pressure and shuttle valve alignment are important diagnostic/maintenance checks for their respective subsystems, but they are not the parameter that verifies proper daily sequencing of the control mechanism.
