Questions and Answers

What is the preferable psi that should be reached when increasing engine rpm?

  • 50 psi
  • 100 psi (correct)
  • 90 psi
  • 75 psi

    • When attaching the supply line to the gated intake valve of the Relay Pumper, what should the operator do?

  • Keep the gate open and open the bleeder valve
  • Keep the gate closed and close the bleeder valve
  • Keep the gate open and close the bleeder valve
  • Keep the gate closed and open the bleeder valve (correct)

    • What should the Attack Pumper operator do when the pumper is receiving excess pressure?

  • Decrease the throttle speed to reduce the output pressure
