Flow Setting - Task Force Tips Metro 1 Instructions For Safe Operation And Maintenance

3.1 FLOW SETTING

The washers are marked with various flow settings. Change washer to the desired setting. The nozzle will flow the indicated amount when
the pressure at the nozzle is at the indicated level.
3.2 WASHER SETTING
To change flow and pressure setting of the Metro, use the
following instructions:
1) Set nozzle into FLUSH.
2) Push baffle down to barrel cone.
3) Remove screw and washer using a 5/32 hex key.
4) Remove pre-set flow washer and slide desired flow
washer onto shaft, desired flow marking facing up.
5) Thread screw with washer back into shaft until snug
( Do not over tighten ).

4.0 NOZZLE CONTROLS
4.1 FLOW CONTROL
4.1.1 LEVER TYPE FLOW CONTROL
On models that use a lever type valve handle, the nozzle is shut off
when the handle is fully forward. The valve handle has six detent flow
positions. These detent positions allow the nozzle operator to regulate
the flow of the nozzle depending on the need or what can be safely and
effectively handled. TFT recommends the use of a pistol grip for easier
handling. For additional stress reduction, a hose rope or strap may
also be used. This permits more effective use and ease of
advancement, while minimizing strain and fatigue.
4.1.2 TWIST SHUTTOFF
On models that use a twist flow control, the valve is opened or closed
by rotating the valve ring. Rotating the ring clockwise (as seen from the
operating position behind the nozzle) closes the valve, while
counterclockwise rotation opens it. Detents are provided at four
intermediate positions and the position of the valve is shown by the
exposed valve position label.

An inadequate supply of nozzle pressure and/or flow will cause an ineffective stream and can
result in injury, death or loss of property. See flow charts in section 3.0 or call 800-348-2686 for
assistance.
Failure to secure screw and washer will result in the baffle becoming loose. This will produce poor
stream, improper flows and possible discharge of the complete baffle, resulting in risk of injury.
Failure to restrain nozzle reaction can cause firefighter injury from loss of footing and/or stream
protection. Nozzle reaction will vary as supply conditions change: such as opening or closing
other nozzles, hose line kinks, changes in pump settings, etc. Changes in spray pattern or flushing
will also affect nozzle reaction. The nozzle operator must always be positioned to restrain the
nozzle reaction in the event of those changes.
Injury from whipping can occur. If nozzle gets out of control or away from operator, retreat from
nozzle immediately. Do not attempt to regain control of nozzle while flowing water.
Fire streams are capable of injury and damage. Do not direct water stream to cause injury or
damage to persons or property.
