1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved
with a particular hazard. Per ANSI standard Z535.4-1998 the definitions of the three signal words are as follows:
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
2.0 GENERAL INFORMATION

WARNING
WARNING
WARNING
WARNING
This equipment is intended for use by trained personnel for firefighting. Their use for
other purposes may involve hazards not addressed by this manual. Seek appropriate
guidance and training to reduce risk of injury.
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 prepared in
the event of those changes. Failure to restrain nozzle reaction can cause firefighter injury
from loss of footing and/or stream protection.
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. Injury from whipping can
occur.
Water is a conductor of electricity. Application of water solutions on high voltage
equipment can cause injury or death by electrocution. The amount of current that may be
carried back to the nozzle will depend on the following factors:
! Voltage of the line or equipment
! Distance from the nozzle to the line or equipment
! Size of the stream
The Fire Fighter and Electrical Equipment,
! Whether the stream is solid or broken
The University of Michigan Extension

! Purity of the water1
CAUTION
Service, Fourth Printing 1983. Page 47.
Fire streams are capable of injury and damage. Do not direct water stream to cause injury
or damage to persons or property.

NH (National Hose Threads per NFPA #1963) threads are standard on all nozzles. Other threads such as NPSH (National
Pipe Straight Hose threads per ANSI/ASME #B1.20.7) can be specified at time of order.
CAUTION
CAUTION
Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle
to leak or uncouple under pressure and could cause injury.
Dissimilar metals coupled together can cause galvanic corrosion that can result
in the inability to unscrew the threads of complete loss of thread engagement
over time. Per NFPA 1962 (1998 edition), if dissimilar metals are left coupled
together an anti-corrosive lubricant should be applied to the threads. Also the
coupling should be disconnected and inspected at least quarterly.

DANGER
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 800348-2686 for assistance.
WARNING
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.
WARNING
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.
WARNING
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.
CAUTION
Fire streams are capable of injury and damage. Do not direct water stream to cause injury
or damage to persons or property.
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.

4.1.3 TIP ONLY NOZZLES
Tip only nozzles have NO shut off valve contained within the nozzle and MUST be used with a separate ball valve
attached to the nozzle.

4.2 BALL VALVE SHUTOFF
Models with a ball valve are shut off when the valve handle is fully forward. Pulling
back on the handle opens the valve. Open valve slowly to avoid sudden changes in
nozzle reaction. Close valve slowly to prevent water hammer. Note: In partially open
positions a ball valve will cause turbulence and adversely affect stream quality.

4.3 PATTERN CONTROL
TFT's Metro 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. NOTE: Turning the shaper further forward will cause stream crossover
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.
4.4 FLUSH CONTROL
Small debris may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach and
reduced flow. To remove this trapped debris the nozzle can be flushed as follows; while still flowing water, turn the
SHAPER counterclockwise past the full fog position (increased resistance will be felt on the SHAPER as the nozzle goes
into flush). This will open the nozzle allowing debris to pass through. Rotate the SHAPER clockwise and out of flush to
continue normal operation. During flush the nozzle reaction will decrease as the pattern becomes wider and the pressure
drops. The nozzle operator must be prepared for an increase of nozzle reaction when returning the nozzle from the flush
position to retain control of the nozzle.
WARNING
Large amounts or pieces of debris may be unflushable and can reduce the flow of the
nozzle resulting in an ineffective flow. In the event of a blockage, it may be necessary
to retreat to a safe area, uncouple nozzle and remove debris.
4.5 USE WITH FOAM
The Metro nozzles may be used with foam solutions. Refer to fire service training for the proper use of foam.
WARNING
WARNING
WARNING
For Class B fires, lack of foam or interruption in the foam stream can cause a break in the
foam blanket and greatly increase the risk of injury or death. Assure that:
! Application rate is sufficient (see NFPA 11 or foam manufacturer's
recommendations).
! Enough concentrate is on hand to complete task (see NFPA for minimum duration
time requirements).
! Foam logistics have been carefully planned. Allow for such things as:
! Storage of foam in a location not exposed to the hazard it protects.
! Personnel, equipment and technique to deliver foam at a rapid enough rate.
! Removal of empty foam containers.
! Clear path to deliver foam, as hoses and other equipment and vehicles are
deployed.
Improper use of foam can result in injury or damage to the environment. Follow foam
manufacturer's instructions and fire service training to avoid:
! Using wrong type of foam on a fire, i.e. Class A foam on a Class B fire.
! Plunging foam into pools of burning liquid fuels.
! Causing environmental damage.
! Directing stream at personnel.
There is a wide variety of foam concentrates. Each user is responsible for verifying that
any foam concentrate chosen to be used with this unit has been tested to assure that the
foam obtained is suitable for the purpose intended.

4.5.1 FOAM ASPIRATING ATTACHMENTS
To increase the expansion ratio, Task Force Tips "MX Foamjet" (model FJ-MX-HM) multi expansion attachment or LX
Foamjet (model FJ-LX-HM) low expansion attachment may be used with the Metro I nozzle and (model FJ-HMX) multi
expansion attachment or LX Foamjet (model FJ-H) low expansion attachment may be used with the Metro II nozzle.
These foam tubes attach and detach quickly from the nozzle. Note: As expansion ratio is increased, the reach of the
nozzle will be decreased due to the greater amount of bubbles in the stream and their inability to penetrate the air.
Generally the reach with foam is approximately 10% less than with water only. Actual results will vary based on brand of
foam, hardness of water, temperature, etc. See Foamjet instruction manual for specific information.

5.0 USE OF METRO NOZZLES
IT IS THE RESPONSIBILITY OF THE INDIVIDUAL FIRE DEPARTMENT OR AGENCY TO DETERMINE PHYSICAL
CAPABILITIES AND SUITABILITY FOR AN INDIVIDUAL'S USE OF THIS EQUIPMENT.
Many factors contribute to the extinguishment of a fire. Among the most important is delivering water at a flow rate
sufficient to absorb heat faster than it is being generated. The flow rate depends largely on the pump discharge pressure
and hose friction loss. It can be calculated using a hydraulic equation such as:
PDP = NP+FL+DL+EL
For additional information on calculating specific hose
layouts, consult an appropriate fire service training manual,
such as IFSTA, or A Guide to Automatic Nozzles, or call TFT's
"Hydraulics Hotline" at 800-348-2686.
PDP = Pump discharge pressure in PSI
NP = Nozzle pressure in PSI
FL = Hose friction loss in PSI
DL = Device loss in PSI
EL = Elevation loss in PSI

6.0 FIELD INSPECTION
TFT's Metro is designed and manufactured to be damage resistant and require minimal maintenance. However, as the
primary fire fighting tools upon which your life depends, they should be treated accordingly.
Use with saltwater is permissible provided nozzle is thoroughly cleaned with fresh water after each use. The service life of
the nozzle may be shortened due to the effects of corrosion and is not covered under warranty.
WARNING
Nozzle must be inspected for proper operation and function according to inspection
checklist on last page before each use. Any nozzle that fails inspection is dangerous to
use and must be repaired before using.
Performance tests shall be conducted on the Metro nozzle after a repair, or anytime a problem is reported to verify
operation in accordance with TFT test procedures. Consult factory for the procedure that corresponds to the model and
serial number of the nozzle. Any equipment which fails the related test criteria should be removed from service
immediately. Troubleshooting guides are available with each test procedure or equipment can be returned to the factory
for service and testing.
Factory service is available with repair time seldom exceeding one day in our facility. Factory serviced nozzles are
repaired by experienced technicians to original specifications, fully tested and promptly returned. Any returns should
include a note as to the nature of the problem, who to reach in case of questions and if a repair estimate is required.
CAUTION
Any alterations to the nozzle and its markings could diminish safety and constitutes a
misuse of this product.
All Task Force Tip nozzles are factory lubricated with high quality silicone grease. This lubricant has excellent washout
resistance and long term performance. If your department has unusually hard or sandy water, the moving parts may be
affected. Foam agents and water additives contain soaps and chemicals that may break down the factory lubrication.
The moving parts of the nozzle should be checked on a regular basis for smooth and free operation, and signs of
damage. IF THE NOZZLE IS OPERATING CORRECTLY, THEN NO ADDITIONAL LUBRICATION IS NEEDED. Any
nozzle that is not operating correctly should be immediately removed from service and the problem corrected.
7.0 REPAIR
Factory service is available with repair time seldom exceeding one day in our facility. Factory-serviced nozzles are
repaired by experienced technicians to original specifications, fully wet tested, and promptly returned. Repair charges for
non-warranty items are minimal. Any returns should include a note as to the nature of the problem and whom to reach in
case of questions.
Task Force Tips assumes no liability for damage to equipment or injury to personnel that is a result of user service.
Repair kits and repair parts are stocked for immediate shipment. Contact the factory or visit the website at www.tft.com for
parts lists, exploded views, test procedures and trouble shooting guides.

12.0 INSPECTION CHECKLIST
Nozzle must be inspected before each use for proper operation and function according
to this checklist. Check that:
1) There is no obvious damage such as missing, broken or loose parts, damaged labels, etc.
2) Coupling is tight and leak free
3) Valve handle moves freely though full range and shuts off flow
4) Nozzle flow is adequate as indicated by pump pressure and nozzle reaction
5) Shaper turns freely and adjusts pattern through full range
6) Nozzle moves smoothly in and out of flush position
WARNING
Any nozzle failing any part of the inspection checklist is unsafe and must have the
problem corrected before use. Operating a nozzle that fails any of the above inspections
is a misuse of this equipment.
13.0 WARRANTY
Task Force Tips, Inc., 2800 East Evans Avenue, Valparaiso, Indiana 46383-6940 ("TFT") warrants to the original purchaser
of its Metro series nozzles ("equipment"), and to anyone to whom it is transferred, that the equipment shall be free from
defects in material and workmanship during the five (5) year period from the date of purchase.
TFT's obligation under this warranty is specifically limited to replacing or repairing the equipment (or its parts) which are
shown by TFT's examination to be in a defective condition attributable to TFT. To qualify for this limited warranty, the
claimant must return the equipment to TFT, at 2800 East Evans Avenue, Valparaiso, Indiana 46383-6940, within a
reasonable time after discovery of the defect. TFT will examine the equipment. If TFT determines that there is a defect
attributable to it, TFT will correct the problem within a reasonable time. If the equipment is covered by this limited
warranty, TFT will assume the expenses of repair.
If any defect attributable to TFT under this limited warranty cannot be reasonably cured by repair or replacement, TFT
may elect to refund the purchase price of the equipment, less reasonable depreciation, in complete discharge of its
obligations under this limited warranty. If TFT makes this election, claimant shall return the equipment to TFT free and
clear of any liens and encumbrances.
This is a limited warranty. The original purchaser of the equipment, any person to whom it is transferred, and any person
who is an intended or unintended beneficiary of the equipment, shall not be entitled to recover from TFT any
consequential or incidental damages for injury to person and/or property resulting from any defective equipment
manufactured or assembled by TFT. It is agreed and understood that the price stated for the equipment is in part
consideration for limiting TFT's liability. Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above may not apply to you.
TFT shall have no obligation under this limited warranty if the equipment is, or has been, misused or neglected (including
failure to provide reasonable maintenance) or if there have been accidents to the equipment or if it has been repaired or
altered by someone else.
THIS IS A LIMITED EXPRESS WARRANTY ONLY. TFT EXPRESSLY DISCLAIMS WITH RESPECT TO THE
EQUIPMENT ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND ALL IMPLIED WARRANTIES OF FITNESS
FOR A PARTICULAR PURPOSE. THERE IS NO WARRANTY OF ANY NATURE MADE BY TFT BEYOND THAT
STATED IN THIS DOCUMENT.
This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
