Tilt the unit back and forth until all water has been drained. Drain the pump and pump head by inverting the entire unit so that the flywheel end is up. Disconnect the suction, exhaust, discharge, and drain hoses.ģ. Release the tank pressure by loosening the filler cap. Remove the fuel tank from the frame and disconnect the pump. Then set the HIGH- and LOW-speed knobs to the previously set positions.Īfter the P-250 pump has been operated and then shut down, it should be prepared for temporary stowage as follows:ġ. If the engine does flood, close the needle valves and crank the engine until it starts. However, use the choke if the engine does not start immediately. If you have to restart a P-250 while the engine is still warm from previous use, pull the starter cord. While the engine is running, check the water pressure to be sure that it remains at the desired level. Use a screwdriver to make this adjustment.ġ3. Adjust the water discharge pressure by turning the pressure regulator to the desired setting. For slow speed adjustment, slow the engine to IDLE by partially closing the throttle with the stop button. Adjust the carburetor HIGH-speed dial to the best operating position. When pressure shows on the gauge, open the outlet valve slowly and allow water to enter the discharge hose.ġ1. This should occur 20 seconds after the pump has been started, at a suction lift of 16 feet.ġ0. Check the pressure gauge to make sure that water pressure is building up. The starter cord will automatically rewind.ĩ. After the engine starts and runs for a few seconds, push the choke knob in toward the control panel. Pull the starting cord rapidly, but do not Turn the HIGH- and the LOW-speed knobs on the control panel three-quarters of a turn to the left from the CLOSED position.Ĩ. Pull the choke knob to the extended position.

Be sure that the wing nut on the manual priming filler bowl is tight.ħ. Place the water outlet valve in the CLOSED position.
If you continue to press the push button after you have once felt resistance, you could damage the diaphragm.Ħ. At this point, stop pressing IMMEDIATELY. Pump fuel to the carburetor by pressing the push button on the tank several times, until you feel some resistance. Connect the hose assembly from the fuel tank to the plug provided on the control panel.ĥ. Clamp the fuel tank to the top of the frame, using the clamps provided for this purpose.Ĥ. Mix the oil and the gasoline thoroughly.ģ. Fill the gasoline tank with a mixture consisting of one-half pint of the specified engine oil to each gallon of gasoline. Make the required suction and discharge connections.Ģ. Open the water outlet valve momentarily to allow the trapped air to escape.ġ. If the pump is operated more than 15 to 20 seconds with the outlet valve in the CLOSED position, the pump may begin to cavitate and speed up as result of the accumulation of air in the impeller housing. If the pump is not primed in 45 seconds, stop the engine, tighten all suction connections and hose couplings, and try priming again. To operate the P-250 pump, proceed as follows:ĭo NOT run the pump more than 45 seconds unless pressure shows on the gauge. Replacement price on this unit is approximately AUD$5000
Hale p250 fire pump manual portable#
‘The P-250 is a gasoline-driven portable pump with an internal-combustion engine. The pumps are designed to start on an LPG canister for 30-60 seconds before switching over to JP5.
These pumps are ex Australian Navy and are tuned to run on JP5 fuel to reduce the fire risk on a boat (US military documents that diesel engines can run on JP5 without damage).
