TASK FORCE TIP®
A. INTRODUCTION
TASK FORCE TIP ULTIMATIC 125. The nozzle you have purchased is
one of your primary tools in saving life and property. It has been
manufactured with great care to give you the finest performance
possible. All components are of top quality and extremely rugged.
With regular inspection and maintenance it will serve you for many
years. This publication is intended for those who prefer to perform
service on their own equipment. Factory service is available and
encouraged, and repair time seldom exceeds 24 hours in our facility.
Factory serviced nozzles are repaired by experienced technicians,
and fully tested before being returned. Task Force Tips assumes no
liability, expressed or implied, for damage to equipment or injury to
personnel that is a result of user service or improper usage, beyond
that of repair or replacement.
AFTER ANY MAINTENANCE OR SERVICE, THE NOZZLE MUST
BE INSPECTED FOR PROPER OPERATION AND FUNCTION PER
2.0 FLOW CHARACTERISTICS AND 9.0 INSPECTION
CHECKLIST IN "TFT HANDHELD AUTOMATIC NOZZLE
INSTRUCTIONS" (LIN-030). REQUEST ADDITIONAL COPIES
FROM FACTORY IF NEEDED.
!
WARNING: ANY NOZZLE THAT FAILS 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.
B. GENERAL INFORMATION
1.) THREADED JOINTS have been secured using Loctite #271
brand thread locking adhesive. Disassembly requires a minimal
application of heat with a oxyacetylene torch to break the bond.
The threads should be heated to approximately 450 F. Excessive
heat application will cause damage to adjacent seals and labels.
Replacement parts must be reinstalled using Loctite #271, or
equivalent. Small vials of Loctite for field service are available;
order part # V5010, LOCTITE MINI DISPENSER.
2.) LUBRICANTS: If parts are disassembled in an area where orings are present, re-assemble using DOW #44 High
Temperature Silicone Grease on all o-rings and surfaces that the
o-rings contact. If nozzle is not disassembled, Break Free CLP
(Spray or Liquid) can be used as described below:
a.) Spray clearance between SLIDER [17] and VALVE
ASSEMBLY [12].
b.) Spray clearance between SHAPER WITH BUMPER [54] and
BARREL CONE ASSEMBLY [47].
c.) Spray valve discs, then cycle the VALVE HANDLE [2] a few
times to spread lubricant into clearances.
d.) Spray lubricant down the front end of the nozzle through
the hole in the shaft.
e.) Spray ball race through clearance between coupling and
valve.
!
CAUTION:
AEROSOL LUBRICANTS CONTAIN
SOLVENTS THAT CAN SWELL O-RINGS IF APPLIED IN EXCESS.
THE SWELLING CAN INHIBIT OPERATION OF THE MOVING
PARTS.
When used in moderation, as directed, the solvents quickly
evaporate without adversely swellings the o-rings. For more
lubrication information see the Task Force Tips Field Lubrication
Procedure document #LIT-106.
3.) LABEL REPLACEMENT: If labels become damaged, remove
old labels with razor knife. Remove adhesive with acetone or
methyl ethyl ketone. Surface must be clean, dry and free from
grease. Carefully apply new label.
4.) ORDERING PARTS: Always specify the serial number of the
nozzle when ordering parts. The number is found on the raised
rim of the SHAPER GUIDE [30]. Be sure to use complete
DESCRIPTION and ORDER #, as printed on the parts list. All
requests for couplings must specify thread size. Pricing
information will be given at time of order.
C. COUPLING SERVICE
1.) GENERAL: Occasional replacement of hose gaskets is
recommended. Replace GASKET GRABBER [9] if severe impact
has caused damage.
2.) COUPLING REMOVAL: Remove PORT PLUG [19] from side
of VALVE ASSEMBLY [12]. Stand nozzle upright with bumper
down and rotate coupling back and forth to allow (28) 3/16"
STAINLESS STEEL BALLS [18] to drop out. When all balls are
out of the groove, the coupling can be removed. Remove
GASKET GRABBER [9] debris screen and O-RING-127 [10] from
the coupling. End pressure is needed to remove and install
coupling balls.
3.) COUPLING INSTALLATION: Place O-RING-127 [10] onto
the rear groove on valve body. Place the GASKET GRABBER [9]
debris screen onto the valve body, raised end in. Put the coupling
on the valve and load balls into the ballgroove through the port in
the valve. Insertion of the balls is easier if the coupling is rotated
slightly back and forth as the balls are loaded. Insert PORT PLUG
[19] into port on side of VALVE ASSEMBLY [12].
4.) TIP ONLY BASE SERVICE: The TIP ONLY BASE [26] is
retained to the front end by threads which are retained by Loctite.
Apply heat to the knurled rib nearest the front of the nozzle.
Damage to seals and labels can be reduced by protecting them
with a wet cloth. The TIP ONLY BASE [26] can now be
unscrewed. Remove and replace O-RINGS [10 and 16]. Clean all
threads, apply Loctite to threads and screw together.
5.) BOLT-ON PISTOL GRIP REMOVAL: PISTOL GRIP [21] is
held on by a SOCKET HEAD CAP SCREW [22]. Remove screw
with a 5/16" Allen wrench. To reinstall, clean thread and apply
Loctite #271. Tighten screw to 20 ft-lbs.
D. VALVE SERVICE PROCEDURE
Tools Required:
3/32" Allen (hex) Wrench
3/16" Allen (hex) Wrench
Loctite #271 Thread Locking Adhesive
Oxyacetylene Torch
Lubricant such as Dow Corning #44 Silicone Grease
1.) VALVE DISASSEMBLY SEQUENCE
a.) HANDLE REMOVAL: Heat and then remove both 5/16-18

x 1/2 BUTTON HEAD SCREWS [4] from VALVE HANDLE [2] using
3/16" Allen wrench. Remove CAM PIN [3] and SAFETY PIN [7]. The
handle may now be pulled up and off. Service to interior valve parts
should be done prior to installing new handle.
b.) SLIDER AND SEAL REMOVAL: Remove #10-32 x 3/16"
SOCKET SET SCREWS [14] from VALVE ASSEMBLY [12],
using 3/32" Allen wrench. Unscrew front portion of nozzle from
valve. SLIDER [17] is pulled out from front of valve. Remove
and discard O-RINGS [11, 15 and 16].
2.) VALVE ASSEMBLY SEQUENCE
a.) SLIDER AND SEAL INSTALLATION: Insert O-RINGS [11,
15 and 16] into proper grooves. Lubricate and insert SLIDER
[17] into valve, aligning groove with corresponding holes in
handle.
b.) HANDLE INSTALLATION: Insert (1) each SPRING [8] and
3/16 DIA. TORLON BALL [6] into lugs in handle, then snap
handle into place, with offset holes FORWARD. Carefully align
the groove on SLIDER [17] with front offset hole in disc and
offset hole in handle. Start SAFETY PIN [7] into offset hole in
handle. Push down into engagement with groove in slider, until
head of SAFETY PIN [7] is flush with handle. Repeat procedure
with CAM PIN [3]. Loctite (2) 5/16-18 x 1/2" BUTTON HEAD
SCREWS [4], and insert through lower handle holes. Thread
each into corresponding center disc hole. Tighten both 5/16-18
x 1/2" BUTTON HEAD SCREWS [4] securely. Handle should
snap firmly and smoothly into all detent positions and SLIDER
[17] should move back and forth.
c.) VALVE SHUTOFF ADJUSTMENT: Shutoff sealing of valve
is adjusted by the threads between the valve body and the
front portion of the nozzle. While holding the VALVE HANDLE
[2] against stops in the OFF position, screw front end into valve
body until contact with valve plug is felt. Actuate the handle to
the ON position then, screw the front end assembly in 1/12 of a
turn further to give valve shutoff compression. Replace #10-32
x 3/16" SOCKET SET SCREWS [14].
d.) VALVE ADJUSTMENT FOR SEVERE COLD: To help
prevent hose line freezing in cold climates, the valve may be
adjusted for intentional leakage by unscrewing the front end
slightly. The valve may then be returned to normal adjustment
during warm weather as stated above.
event that this should need service, please return the complete
nozzle to the factory for repairs, or replace the entire barrel
assembly.
1.) FRONT END DISASSEMBLY SEQUENCE
a.) SHAPER REMOVAL: The rubber bumper and stream
shaper are molded together as a single unit SHAPER WITH
BUMPER [54]. The shaper is attached to the SHAPER GUIDE
[30] by a threaded joint that is retained by Loctite #271. Grip
rear portion of nozzle in vise with padded jaws. Direct a hot
narrow flame around the rear portion of the shaper. Heat for
approximately 20 seconds, being careful not to damage the
bumper or labels (a wet rag wrapped around these areas will
help). Use a strap wrench to unscrew the shaper from the
shaper guide. Remove the shaper. Inside the shaper are (46)
1/8" DIA. NYLON BALLS [53], some of which will fall free as it is
removed. If the shaper is to be reused, clean ball track and
replace QUADX-4225 [52]. Service to remaining front end parts
must be done before reinstalling shaper.
b.) SHAPER GUIDE REMOVAL: The SHAPER GUIDE [30]
may be serviced by removing the (4) 7/32" DIA. TORLON
BALLS [32]. The SHAPER GUIDE [30] can then be removed
from the BARREL ASSEMBLY [33 or 36]. The balls are intended
as a "fuse" to prevent permanent damage to BARREL
ASSEMBLY [33 or 36]. In the event of severe impact they will
shear off. The pattern control however will remain functional by
merely sliding back and forth.
2.) FRONT END ASSEMBLY SEQUENCE
a.) SHAPER GUIDE INSTALLATION: Slide SHAPER GUIDE
[30] over BARREL ASSEMBLY [33 or 36]. Insert (4) 7/32" DIA.
TORLON BALLS [32].
b.) SHAPER INSTALLATION: Install QUADX-4225 [52] in front
groove of SHAPER WITH BUMPER [54]. Grease the seal and
ball groove heavily. Place (46) 1/8" NYLON BALLS [53] into
greased ballgroove. Apply Loctite #271 to male thread on
SHAPER GUIDE [30]. Start shaper onto shaper guide threads,
screw down until threads bottom.
