    • Intake Relief Valve: Checking and adjusting the intake relief valve.

    Chapter 3: Operation

    • Approaching the Apparatus: Safety precautions for entering and exiting the vehicle, including stepping, walking surfaces, and compartment doors. Avoid climbing or walking on potentially unsafe areas.

    • Hose: Storage, restraint, and deployment procedures. Securely restrain hoses while in motion to prevent entanglement and injury.

    • Pump Engagement and Disengagement: Procedures for engaging and disengaging the driveline-driven pump, including manual override options (optional), for PTO-driven pumps (stationary/driving).

    • Supply and Discharge Water and Foam: Procedures for supplying water to the pump, and discharging water or foam.

    • Changing Water Supply (Tank to External): Procedures for transferring water from the tank to another external supply (e.g., hydrant).

    • Pump Pressure Control and Systems Monitoring: Procedures for controlling engine speed according to pump pressure requirements.

    Chapter 4: Maintenance

    • General Maintenance: Annual testing, cleaning, and maintenance schedules for the apparatus.

    • Pump Maintenance: Procedures for draining, flushing parts of the apparatus, and other pump-related maintenance.

    Additional Information

    • Engine Status Display: Critical performance details like engine speed, oil pressure, oil temperature, electrical system voltage can be monitored by observing the status display.

    • Ending Water Flow Operation: Describes procedures for shutting off water flow, disengaging the pump and securing the pumping system.
