1.0 MEANING OF SAFETY SIGNAL WORDS
Asafety 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 Z535.6-2006, 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, may result in minor
or moderate injury.
NOTICE NOTICE is used to address practices not related to personal injury.
1.1 SAFETY
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 5.0 or call 800-348-2686 for
assistance.
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.
WARNING 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.
WARNING 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.
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.

2.0 GENERAL INFORMATION
The Task Force Tips Twister and Bubblecup nozzles are hand-held nozzles with clean far reaching straight stream. They are
adjustable from straight stream to a wide fog pattern. Their rugged construction is compatible with the use of fresh water as well as
fire fighting foam solutions. The nozzles are constructed of hard anodizes aluminum, stainless steel, rubber and engineering grade
polymers. A summary of each nozzle’s characteristics is shown in the tables below.
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.

CAUTION Fire streams are capable of injury and damage. Do not direct water stream to cause injury or
damage to persons or property.
CAUTION Do not couple aluminum to brass. Dissimilar metals coupled together can cause galvanic
corrosion that can result in inability to unscrew threads or complete loss of thread
engagement.
CAUTION The nozzle may become damaged if allowed to freeze while containing water. Always drain
after use to avoid damage and possible loss of use.
CAUTION Nozzle must be mated to a hose line with matched threads. Mismatched or damaged threads
may cause nozzle to leak or uncouple from hose under pressure and could cause injury.

3.1 FLOW CONTROL
3.1.1 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 ball valve 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.
3.1.2 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.

4.0 BUBBLECUP NOZZLES
The Bubble Cup nozzle is capable of producing aspirated foam as well as a conventional straight stream and wide protective fog
pattern. The Bubble Cup functions just like the Twister nozzle (see section 3.0) when the gray sleeve is in the retracted position as
in figure 3A.
To use the aspirating feature of the Bubble Cup, the nozzle operator need only slide the gray sleeve portion of the nozzle forward.
When the sleeve is in the fully-extended position, a white line on the shaper will be visible at the base of the gray sleeve as in
figure 3B. Rotation of the shaper when the sleeve is extended will provide the nozzle operator control of reach and aspiration. If an
immediate wide protective fog pattern is needed, the sleeve can be retracted instantly to its regular position.

FIGURE 3 BUBBLE CUP OPERATING POSITIONS
3.1.2 BALL 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. Note: In partially-open positions a ball valve will cause turbulence and adversely
affect stream quality. Close valve slowly to prevent water hammer.
3.2 PATTERN AND FLUSH CONTROL
3.2.1 PATTERN CONTROL
TFT’s Twister and BubbleCup 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 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.
Low & High / Straight Stream Low & High / Medium Fog High /Wide Fog
FIGURE 2 CHANGING PATTERN AND FLOW SETTINGS
WARNING Large amounts of debris 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.

6.0 USE WITH SALT WATER
Use with salt water 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.
7.0 FOAMJET MX WITH TWISTER NOZZLE
To increase the expansion ratio Task Force Tips “Foamjet MX”
(model FJ-MX-D) may be used with the Twister nozzle. This
multi-expansion foam tube attaches and detaches quickly from
the nozzle. Note:As expansion ratio is increased, the reach of the
stream 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.

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.• Keeping clear path to deliver foam as hoses, other equipment and vehicles are• deployed.
WARNING 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.•
WARNING 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.
8.0 FIREGROUND USE OF TWISTER AND BUBBLE CUP NOZZLES
ITISTHERESPONSIBILITYOFTHEINDIVIDUALFIREDEPARTMENTORAGENCYTODETERMINEPHYSICALCAPABILITIES
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 is being generated. The flow rate depends largely on the pump discharge pressure and hose friction loss.
The pump discharge pressure may be found by use of the chart on the last page. It can also 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

9.0 FIELD INSPECTION
Twister and Bubble Cup 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.
WARNING Before each use nozzle must be inspected for proper operation and function according to
inspection checklist in section 10.0 of this document. Any nozzle that fails inspection is
dangerous to use and must be repaired before using.
Performance tests shall be conducted on the Twister and Bubble Cup nozzle after a repair, or anytime a problem is reported to
verify operation in accordance with Task Force Tips 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 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.
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.
SPECIAL CONFIGURATIONS; If nozzles are made according to the special marking or performance requirements of the fire
department then the operating characteristics may differ from the published data in this manual. Repair parts specific to each serial
number may differ from those shown in the service procedure. The required parts for each serial number are available on-line by
entering www.tft.123456 the with numbers corresponding to the serial number engraved on the product.
Consult TFT for laser engraved handle covers, special labeling, logos, and special laser engraving on the nozzle.
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.
10.0 INSPECTION CHECKLIST
Nozzle must be inspected for proper operation and function according to this checklist before each use.
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 and shuts off flow
6) On Bubble Cups, aspirating sleeve slides freely and is secure at both ends
If a nozzle needs service, refer to the following documents:
Service Procedure: 1.0” Twister and 1.0” BubbleCup LKD-010
Service Procedure: 1.5” Twister and 1.5 “ BubbleCup LKF-010
WARNING Any twister or bubble cup 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.
