Which step comes immediately before chocking the wheels in the stationary PTO operation sequence?

• A. Position the MWS apparatus
• B. Place the transmission in neutral
• C. Set the parking brake
• D. Operate the PTO control

Answer: (D)

Engaging the PTO to power the pump is the action that directly precedes securing the vehicle with wheel chocks. The PTO control activates the drive to the pump, establishing the hydraulic load and confirming the system is ready for stationary operation. Once the PTO is engaged and the pump is ready, you apply wheel chocks to prevent any movement that could be caused by pump torque or engine vibrations. The other steps—positioning the MWS apparatus, placing the transmission in neutral, and setting the parking brake—are performed earlier to prepare a safe setup, but the step that comes immediately before chocking is activating the PTO.
