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.

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 & 8.0 or call

800-348-2686 for assistance.

Fire streams are capable of injury and damage. Do not direct water stream to cause injury

or damage to persons or property.

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.

4.0 NOZZLE CONTROLS

3.1 WASHER SETTING

Tip only nozzles have NO shut off valve contained within the nozzle and

be used with a separate ball valve or

attached to a monitor.

MUST

To change flow and pressure setting of the Metro II, use

the following instructions:

1) Set nozzle into FLUSH.

2) Push baffle down to barrel cone.

3) Use snap ring wrench to remove snap ring from shaft.

4) Remove pre-set washer and slide desired washer

onto shaft, markings facing up.

5) Put snap ring back onto the shaft in the groove.

SNAP RING

WASHER

(H410-**)

SHAFT

(H470)

BAFFLE

(H461)

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.

4.1 PATTERN CONTROL

TFT's Metro II has full pattern control from straight stream to wide fog. Turning the STREAM SHAPER clockwise (as seen

from the operating position behind the nozzle) moves the SHAPER to the straight stream position. Turning the SHAPER

counterclockwise will result in an increasingly wider pattern.
Since the stream trim point varies with the flow, the stream should be "trimmed" after changing the flow to obtain the

straightest and farthest reaching stream. To properly trim a stream, first open the pattern to a narrow fog. Then close the

stream to parallel to give maximum reach.

The nozzle reaction is greatest when the shaper is in the straight stream position. The nozzle operator must be prepared

for a change in reaction as the pattern is changed.

NOTE: Turning the shaper further forward will cause stream crossover

and reduce the effective reach of the nozzle.
