    You are responsible for learning how to operate the pumper under all conditions without having to read this manual at a fire or other emergency.

  • Page 8: Responsibility

    Your department developed specifications for this fire apparatus. It purchased a Pierce apparatus that is built to meet those specifications. The information in this manual will be generic at times. Due to the highly customized nature of each Pierce fire apparatus, the exact location of each component in the pumper system will vary.

    Some departments choose to connect a hose to the relief valve outlet to direct the water discharge away from the apparatus. Pressure surges in this hose can occur without warning. Pierce Pumper / 2-1 © 2019 Pierce Manufacturing Inc. All Rights Reserved.
  • Page 16 To adjust this valve for desired pressure, the intake pressure to the pump must be higher than the normal static pressure of the municipal water supply. The best method to adjust the valve is to use another pumper to supply water at the desired pressure.

  • Page 19: Hose

    Some aerial apparatus have a hose “chute.” The chute guides the hose from the hose bed around the aerial turntable, then out the back of the vehicle. NEVER pack hose in the hose chute, because that can cause snagging and snarling. Pierce Pumper / 3-3 © 2019 Pierce Manufacturing Inc. All Rights Reserved.
