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 Z535.6-2011, the definitions of the four signal words are as follows:
DANGER
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE
NOTICE is used to address practices not related to physical injury.
SAFETY INSTRUCTIONS (or equivalent) signs indicate specific safety-related instructions of procedures.
2.0 SAFETY
DANGER
WARNING
WARNING
WARNING
WARNING
WARNING
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 graphs or call 800-348-2686 for assistance.
The nozzle may be damaged if frozen while containing significant amounts of water. Such
damage may be difficult to detect visually and can lead to possible injury or death. Any time the
nozzle is subject to possible damage due to freezing, it must be tested by qualified personnel
before being considered safe for use.
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.
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 prepared in the
event of these changes.
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 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
• Whether the stream is solid or broken
• Purity of the water1

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

3.3 NOZZLE COUPLINGS
Many inlet couplings such as NH (National Hose) is standard or NPSH (National Pipe Straight Hose) and other threads can be
specified at time of order.
CAUTION
CAUTION
Nozzle must be mated to a hose line with matched threads. 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 or complete loss of thread engagement over time. Per NFPA 1962, 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.
3.4 USE WITH SALTWATER
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.
4.0 FLOW CHARACTERISTICS
4.1 FIXED FLOW
A fixed flow G-Force nozzle has one fixed discharge orifice and a flush setting. A fixed flow G-Force is flush able with the selector
ring. Figure 4.2 shows flow and pressure graphs for the G-Force Fixed nozzles.
4.2 SELECTABLE FLOW

5.0 NOZZLE CONTROLS
Nozzle control valves must be opened slowly to eliminate unnecessary strain on the hose and couplings and reduce pressure
surges.
Nozzles attached to an in-service hose shall be stored in the off position.
5.1 FLOW CONTROL
5.1.1
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 5
detented 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.

5.1.2 TIP ONLY
Tip only nozzles have NO shut-off valve within the nozzle and
MUST be used with a separate ball valve attached to the nozzle.
5.1.3
BALL SHUT OFF
A separate ball valve for use with Tip Only nozzles is 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. Nozzles attached to an inservice hose shall be stored in the off position.
5.1.4 IMPULSE TRIGGER FLOW CONTROL
LOCK
TRIGGER
ON
NOTE: THE TRIGGER RETURNS TO OFF
IF NOT HELD OR LOCKED
OFF
Do not intentionally release the nozzle while flowing and trust the valve to shut off automatically.
The trigger nozzle’s ability to shut off by itself represents an extra level of safety when following
normal nozzle handling procedures. To rely on it as the sole means of safety increases the risk of
injury from an out of control nozzle. Release nozzle when flow has stopped.

WARNING
5.1.4.1 IMPULSE TRIGGER LOCK
To Lock: Push on the lock while pulling back the trigger to
engage one of the four locked positions.
LOCK
LOCK PIVOT PIN
To Un-Lock: Pull back slightly on trigger without any pressure
on the lock. The spring loaded lock should automatically move to
the unlocked position.
TRIGGER
Use an 1/8” (3mm) punch to push out pin
and remove lock if the lock is not desired.
WARNING
When the trigger lock is engaged, the nozzle will not shut off if dropped. Always shut off nozzle
before releasing the pistol grip to avoid injury from an out of control nozzle.
5.1.4.2 TRIGGER FLOW CONTROL SPEED ADJUSTMENT
The IMPULSE valve contains a slow close mechanism to prevent the nozzle from slamming off if the trigger is suddenly released.
The closing speed is set at the factory to be slow enough to reduce water hammer, (“water hammer” is always present in any valve
when it is shut off. The slow close mechanism will reduce this but cannot eliminate it completely) but fast enough to reduce the
potential danger of hose whipping from a dropped nozzle. The closing speed may be adjusted as shown in the figure.5.1.4.2.
Faster
Close
Slower
Close
Figure 5.1.4.2
Do not unscrew the adjuster past the end of the hand grip (to unscrew it too far could result in the loss of dampening fluid.)
WARNING
As the closing time is increased so does the risk of injury from an out of control nozzle. A flowing
nozzle can cause injury within the first second of lost control. Use caution when adjusting the
closing speed and always verify performance after adjustment.

5.2 PATTERN AND FLUSH CONTROL
FLOW
OFF
ON
5.2.1 PATTERN CONTROL
TFT’s nozzles have 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 flow, the stream
should be “trimmed” after changing the flow to obtain the
straightest and farthest reaching stream. To properly trim
the stream, first open the pattern to 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.
Care must be taken to avoid dents or nicks in the nozzle tip
because they can seriously affect the stream reach.

FLOW
OFF
ON
COUNTERCLOCKWISE
TACTILE INDICATOR
(MOVES WITH BUMPER)
5.2.2 SHAPER TACTILE INDICATOR
The G-Force has a tactile indicator on the stream shaper.
The tactile indicator allows the stream shaper position
(and fog angle) to be determined by feel rather than by
sight. The fog angle can be adjusted (see section 5.2.3)
so that a desired fog angle is achieved when the tactile
indicator in on top of the nozzle. The G-Force has an
optional detent to aid in returning to a known fog angle.
Note: The fog angle will change as flow and pressure
change (becoming wider with increased flow).
5.2.3 FOG ANGLE ADJUSTMENT
Typically the G-Force is factory set with the tactile indicator
in the top position for straight stream. The fog angle can
be adjusted while keeping the tactile indicator on top by
following the steps in figure 5.2.3. You will need a new
shaper label if you change the fog angle adjustment.
1) Remove or cut the shaper label.
2) Loosen the clamp ring
with a pin spanner.
5) Apply a new shaper label.
4) Tighten the clamp ring
with a pin spanner.
3) While keeping the tactile indicator
or lock out lever on top,
rotate the shaper guide
to obtain the desired fog angle.

LIG-010 July 6, 2015 Rev04
5.2.4 FLUSH CONTROL
Small debris passes through the debris screen (if equipped) and may get caught inside the
nozzle. This trapped material will cause poor stream quality, shortened reach, and reduced
flow. To remove small debris, the nozzle may be flushed as follows:
• While still flowing water, rotate the shaper counterclockwise (as viewed from behind
the nozzle) to the flush position. (increased resistance will be felt on the SHAPER or
RING as the nozzle goes into flush) This will open the nozzle allowing debris to pass
through.
• 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.
• Rotate the selector ring out of flush to continue normal operations.
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 the nozzle and remove debris.
WARNING
6.0 USE WITH FOAM
The G-Force nozzle may be used with foam solutions. Refer to fire service training for the proper use of foam.
WARNING
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 fires.
• Causing environmental damage.
• Directing stream at personnel.
There are 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.
Use of compressed air foam (CAF) with hand held nozzles can cause sudden surges in nozzle
reaction force resulting in risk of injury or death from loss of footing or hose whipping. Be
prepared for sudden changes in nozzle reaction caused by:
• Slug loading (Loss of foam concentrate sends slugs of air and water into the nozzle)
• Sudden release of built-up pressure in the hose when opening a nozzle
6.1 FOAM ASPIRATING ATTACHMENTS
To increase the expansion ratio, G-Force Series MX Foamjet (model FJ-MX-G) multi-expansion attachment or LX Foamjet (model
FJ-LX-G) low expansion attachment may be used with G-Force nozzles. 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 ability 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. See LIA-025 (MANUAL: Foam Attachments for TFT Nozzles).
7.0 USE OF G-FORCE 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
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

12.0 MAINTENANCE
TFT nozzles are designed and manufactured to be damage resistant and require minimal maintenance. However, as the primary
firefighting tool upon which your life depends, it should be treated accordingly. To help prevent mechanical damage, do not drop or
throw equipment.
12.1 FIELD LUBRICATION
All Task Force Tips’ nozzles are factory lubricated with high quality silicone grease. This lubricant has excellent wash out resistance
and long term performance in firefighting nozzles. If your department has unusually hard or sandy water, the moving parts of the
nozzle 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 for signs of damage. IF THE
NOZZLE IS OPERATING CORRECTLY, THEN NO ADDITIONAL LUBRICANT IS NEEDED. Any nozzle that is not operating correctly
should be immediately removed from service.
The field use of Break Free CLP (spray or liquid) lubricant will help to restore the smooth and free operation of the nozzle. However,
these lubricants do not have the washout resistance and long-term performance of the silicone grease. Therefore, re-application of
Break Free CLP will be needed on a regular basis. CAUTION: Aerosol lubricants contain solvents that can swell O-Rings if applied
in excess. The swelling can inhibit smooth operation of the moving parts. When used in moderation, as directed, the solvents quickly
evaporate without adversely swelling the O-Rings.
The nozzle can be returned to the factory for a complete checkup and re-lubrication with silicone grease
PART ONE — COUPLING DOWN
Position the nozzle at a 45-degree angle with the COUPLING
end down. Set the pattern to STRAIGHT STREAM. Then spray
a short burst into these areas:
#1 FRONT PATTERN CONTROL SEAL
Spray in between the pattern control and the barrel.
#2 PRESSURE CONTROL UNIT
Spray in between the baffle and sub-baffle.

12.2 IMPULSE TRIGGER VALVE LUBRICATION
1) Insert tube from BreakFree into drain
hole in pistol grip.
Holding a rag around the tube here
can help keep excess BreakFree
from the outside of the nozzle.
2) With nozzle upside down spray a 2
second burst into the pistol grip.
Holding a rag around the tube here
can help keep excess BreakFree
from the outside of the nozzle.
3) Keep nozzle upside down for at least
10 seconds to allow the BreakFree to
flow into the valve area.
4) Check for smooth and free operation
of the trigger. Repeat a second time if
needed.
If this procedure does not restore trigger operation then factory service is needed.

12.3 SERVICE TESTING
In accordance with NFPA 1962 (2013), nozzles must be tested a minimum of annually. Nozzles failing any part of this test must be
removed from service, repaired and retested upon completion of the repair.
12.3.1 HYDROSTATIC TESTING
Each nozzle with a shut off mechanism shall be tested in the following manner.
1. The nozzle shall be placed in a device capable of holding it and the shut off shall be closed.
2. A device capable of exerting a hydrostatic pressure of 300 psi (2070 kPa) or 1.5 times the maximum operating pressure,
whichever is higher, shall be attached to the nozzle.
3. All air shall be bled from the system.
4. The gage pressure shall be increased by 50 psi (3.5 bar or 345 kPa) increments, held for 30 seconds at each pressure up to
the maximum pressure for which the nozzle is being tested, and then held for one minute without leakage.
5. There shall be no sign of leakage through the valve or shut off.
12.3.2 FLOW TESTING
Flow testing must be conducted in the following manner.
1. The nozzle shall be mounted so that the flow rate and pressure through the nozzle and the pressure at the inlet can be
accurately measured.
2. With the shut off fully open, the inlet pressure shall be adjusted to the rated pressure ±2 percent.
3. The valve or shut off and pattern controls shall be operated through their full range of motion at 100 psi (6.9 bar or 690 kPa)
with no signs of leaking, binding or other problems.
4. Evaluate the flow of nozzles as defined by NFPA 1964 in the following manner:
Automatic (Constant Pressure) Spray Nozzles
1. The flow rate shall slowly be increased to the maximum rated flow, and the minimum and maximum pressures through
the flow range recorded.
2. Nozzles shall maintain their rated pressure ±15 psi (±1 bar or ±100 kPa) throughout the rated flow range.
12.3.3 RECORDS
A record of testing and repairs must be maintained from the time the nozzle is purchased until it is discarded. Each TFT nozzle is
engraved with a unique serial number which, if so desired, can be used to identify nozzle for documentation purposes.
The following information, if applicable, must be included on the test record for each nozzle:
1. Assigned identification number
2. Manufacturer
3. Product or model designation
4. Vendor
5. Warranty
6. Hose connection size
7. Maximum operating pressure
8. Flow rate or range
9. Date received and date put in service
10. Date of each service test and service test results
11. Damage and repairs, including who made the repairs and the cost of repair parts
12. Reason removed from service

12.4 REPAIR
Factory service is available with repair time seldom exceeding one day in our facility. Factory-serviced nozzles are repaired by
experienced technicians, wet tested to original specifications, 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.
Repair parts and service procedures are available for those wishing to perform their own repairs. Task Force Tips assumes no liability
for damage to equipment or injury to personnel that is a result of user service. Contact the factory or visit the web site at www.tft.com
for parts lists, exploded views, test procedures and troubleshooting guides.
Performance tests shall be conducted on the 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.
CAUTION
Any alterations to the nozzle and its markings could diminish safety and constitutes a misuse
of this product.
13.0 OPERATION AND INSPECTION CHECKLIST
BEFORE EACH USE the nozzle must be inspected to this checklist:
1) There is no obvious damage such as missing, broken or loose parts, damaged labels etc.
2) Debris screen is free of debris
3) Coupling is tight and leak free
4) Valve operates freely through full range and regulates flow
5) “OFF” position does fully shut off and flow is stopped
6) Nozzle flow is adequate as indicated by pump pressure and nozzle reaction
7) Shaper turns freely and adjusts pattern through full range
8) Shaper turns into full flush and out of flush with normal flow and pressure restored
9) Shaper detent (if so equipped) operates smoothly and positively.
BEFORE BEING PLACED BACK IN SERVICE, nozzles must be inspected to this checklist;
1) All controls and adjustments are operational
2) Shut off valve (if so equipped) closes off the flow completely
3) There are no broken or missing parts
4) There is no damage to the nozzle that could impair safe operation (e.g. dents, cracks, corrosion or other defects)
5) The thread gasket is in good condition
6) The waterway is clear of obstructions
7) Nozzle is clean and markings are legible
8) Coupling is retightened properly
9) Shaper is set to desired pattern
10) Shutoff handle is stored in the OFF position

WARNING
Any nozzle failing any part of the checklist is unsafe for use and must have the problem corrected
before use or being placed back into service. Operating a nozzle that has failed the checklist is
a misuse of this equipment.
