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 chart in section 8.0 or call 800-3482686 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, flushing, or pressure control knob 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.
3.0 NOZZLE CONTROLS
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 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.
3.1.2 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.
3.1.3 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.
3.2 PATTERN AND FLUSH CONTROL
3.2.1 PATTERN CONTROL
The TFT's MID-FORCE and DUAL-FORCE 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.
4
3.2.2 FLUSH CONTROL
Small debris passes through the gasket grabber and 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 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.
FIGURE 3 - GASKET GRABBER
3.3 STANDARD/LOW PRESSURE KNOB
For situations where 100 PSI at the nozzle is impractical, the MID-FORCE or DUAL-FORCE may be switched to an low
pressure mode. In the low pressure mode the nozzle pressure is reduced by about 50% while maintaining a usable
stream and increasing the flow. The nozzle operator must be prepared for a change in reaction when changing modes.
See figure 2 or the flow chart in section 8.0 for actual performance.
To switch to the low pressure mode, shut off water flow with valve and turn knob at front of nozzle (see figure 4)
counterclockwise (when viewed from front). Reopen valve to flow water at reduced pressure. Repeat the process,
except turn knob clockwise, to return to 100 PSI operation.
To obtain dual pressure capability, a knob is added to the front end of the baffle. This knob protrudes past the end
of the nozzle when the shaper is rotated back. As a consequence, the knob and baffle may be damaged if
subjected to impact such as from a drop. The knob and baffle portion of the nozzle does NOT meet NFPA 1964's
rough usage requirement of a six foot drop onto concrete (paragraph 4-7.1). In the event of damage to this section
the stream quality may be affected as well as nozzle pressure regulation.

4.0 USE OF MID-FORCE and DUAL-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. The pump discharge pressure may be found by use of the chart in section 8.0. It can also be
calculated using a hydraulic equation such as:
Within its flow range, the nozzle pressure (NP) of the MID-FORCE
or DUAL-FORCE nozzle may be approximated as 100 PSI in the
standard mode. For additional information on calculating specific
hose layouts, consult an appropriate fire service training manual,
A Guide to Automatic Nozzles, or call TFT's "Hydraulics Hotline" at
800-348-2686.
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
5.0 FIELD INSPECTION
TFT's MID-FORCE and DUAL-FORCE are 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 the 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 Mid-Force and Dual-Force 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.

Title
Mid-Matic & Mid-Force Service Procedure
Dual-Force Service Procedure
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.

9.0 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) Gasket grabber 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) Standard/low pressure knob turns freely and changes nozzle pressure.
WARNING
Any Mid-Force or Dual-Force 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.
