3.1 WASHER SETTING
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.
3.2 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.

4.0 NOZZLE CONTROLS
Tip only nozzles have NO shut off valve contained within the nozzle and
attached to a monitor.
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.
and reduce the effective reach of the nozzle.
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.

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.
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.
NOTE: Turning the shaper further forward will cause stream crossover
