Flow Control Valve Operation; Unlocking The Valve Handle From The Closed Position - Task Force Tips BLITZFIRE Series Instructions For Safe Operation And Maintenance

3.3 FLOW CONTROL VALVE OPERATION

The Blitzfi re has a valve that can be used to control the fl ow
and acts as a safety shut-off feature. The valve is shut-off when
the valve handle is fully forward. The valve is fully on when the
valve handle is fully back. The valve can be opened to any of
six detented fl ow positions. These detented positions allow the
monitor operator to regulate the fl ow depending on the need or
what can be safely and eff ectively handled.

3.3.1 UNLOCKING THE VALVE HANDLE FROM THE CLOSED POSITION

The valve handle is locked in the closed position so that the valve handle may be
used to carry the Blitzfi re without the valve inadvertently opening. To unlock the valve
handle from the closed position:
1. Pull knob on right side of the valve handle.
2. While pulling on knob, open the valve with the other hand.
As soon as valve is opened the knob may be released. The valve handle may be
moved to any detent valve position by pushing or pulling on the valve handle. When
the valve is closed the valve handle automatically locks and must be unlocked again
to reopen. The valve opening procedure is shown in fi gure 3.3.1.
