Our instructions for the aux pump is only IF the main pump is U/S and only for emergency use (ie crew protection).
Ahhh thanks for clarifying that Fastlane, don't have that on our 2 light tankers...does it apply to 1.4's at all or is that all standard pumps like LT's?Fastlane wrote:You can crawl about with good pressure on a fireground using the Live Drive PTO with very little problem. If you can't manage it, you aren't operating the appliance correctly.
On the current appliances the auxiliary pump can be started from inside the vehicle cab. Older appliances only have a start switch on the pump itself. The aux pump is designed to operate the off-side hosereel and backup hose that sits behind the tray headboard ONLY. Of course, if you leave the water valve that feeds from the main pump on the off-side hosereel open, it will feed back through the rest of the system.
Tyranus, all of 2.4's etc that have PTO have a "Live Drive" system which allows the appliance to move whilst the PTO is engaged - if this wasn't possible, we'd all have Hatz Diesel Pumps on the back of our appliances still.
Note that career staff had something against the Live Drive, even though it is tried and tested in the field. This is why the career 2.4's have a Hatz Pump Set on the back.
The spay is on jet in that pic, it can be widened.
Best Description i've yet to hear..
