This Instructable is designed to give a person a basic knowledge about how to pump a fire truck quickly and efficiently
Step 1: Getting to the Scene
In order to properly to pump a truck, one must get to the emergency scene in a safe and secure manner. Once the crew and engineer are safely on scene, the pumpinng set up and process can begin.
Step 2: Hitting the Hydrant
The most important yet overlooked aspect of pumping a fire truck is WATER. In order to have adequate pumping one must connect the main supply hose to the hydrant which in turn flows into the engine.
Step 3: Engaging the Pump
Once the truck is in position, it is time to begin pumping. First, the driver must engage the pump. To do this, the driver must use a button as seen in the picture. The driver must first place the button to neutral. Then the driver must place the button into pump then press the DRIVE button as if he were putting the truck into motion. Note: by doing this the truck will not move due to the airbrake being in use.
Step 4: Hose
Prior to pumping, the driver must make sure the hose is fully out of the rack and ready for water. Once this completed, the driver can continue.
Step 5: Priming the Pump
The driver must next prime the pump to prepare it for use. To do this, the driver must press the "PRIME" button for at least 10 seconds
Step 6: Tank to Pump
Once priming is complete, the driver can now begin to flow water. To do this, the driver must pull the lever labeled "Tank to Pump". This lever enables the water to be drawn from the tank on the truck into the pump which will then be sent to the hose.
Step 7: The Magic "Preset" Button
Next, the driver needs to use the pump throttle to assist in pumping. Most newer trucks come with a throttle panel that makes it easier to use. All the dirver has to do is press the "Preset" button and this automatically sets the throttle to 130 psi.
Step 8: Charging the Hose
Next, the driver can pull any lever and adjust it to the appropriate psi as required. By setting the preset, the driver can adjust the levers to the appropriate psi making sure that the appropriate pressure is flowing through the hose.
Step 9: Additional Helpful Steps
Next, if the driver chooses, they can pull the "Tank Fill" lever. This will enable the truck to refill its tank while still pumping water to the firefighters. That is as simple as firefighting gets!!!!
