Maintenance and Service Procedure
For Nozzles with: Serial # TFT-H465101 and over
or Manufactured after 12/01/2003
INTRODUCTION
TASK FORCE TIPS AUTOMATIC: The nozzle you have purchased is your primary
tool in the battle against fi re. It has been manufactured with great care to give you
the fi nest performance possible. All components are of top quality and extremely
rugged. With regular inspection and attention 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 in most cases,
seldom exceeds 24 hours one day in our facility. Factory serviced equipment is
serviced by experienced workmen and fully tested before being returned. Repair
charges for non-warranty items are usually minimal and all serviced equipment is
promptly returned functioning to original specifi cations. Task Force Tips assumes
no liability, expressed or implied for damage to equipment or injury to personnel
that is a result of user service. IMPORTANT: After any maintenance or service,
always check nozzle for proper operation per INSPECTION CHECKLIST and fl ow
characteristics in “MANUAL: HAND-HELD AUTOMATIC NOZZLES” (LIN-030).
GENERAL INFORMATION
TOOLS REQUIRED
The following tools are required for general service to the nozzle:
3/32, 1/8, 7/32 and 5/16 Allen wrenches
Dow #112 Lube/sealant
Loctite #271 thread locking adhesive
oxyacetylene
torch
razor
knife
Additional tools needed to service the shaper are:
strap
wrench
vise with padded jaws
Handline / Dual-Force shaper removal clamp
(special tool TFT #THM-502)
Additional tools needed to service the pressure control are:
dental
pick
two small probes, approximately 3/32 dia (such as a drill bit)
drill press, 17 inch opening
THREADED JOINTS: have been secured using Loctite® #271 thread locking adhe-
sive. Disassembly requires a minimal application of heat with an 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® #271
for fi eld service are available; order Part # V5010, (Loctite® #271 - Mini Dispenser).
LUBRICANTS: If parts are disassembled in an area where O-rings are present,
reassemble using DOW #112 Lube on all O-rings and surfaces that the O-rings
contact. Call Dow Corning® Corp. at 800-447-4700 for the name of your nearest
distributor. The lube is also available through TFT as item number VSA-101. If the
nozzle is not disassembled refer to Field Lubrication Procedure Section (on back).
LABEL REPLACEMENT: If labels become damaged, remove old labels with a ra-
zor knife. Remove adhesive with acetone or methyl ethyl ketone. Surface must be
clean, dry and free from grease. Carefully apply new label.
ORDERING PARTS: Always specify the serial number of the nozzle when ordering
parts. The serial number is found on the back of the nozzle next to the coupling.
Be sure to use complete DESCRIPTION and ORDER #, as printed on parts list. All
requests for couplings must specify thread size. Pricing information will be given
at time of order. Parts and Repair Kits may be purchased on-line at www.tft.com

COUPLING AND BASE SERVICE PROCEDURE
TOOLS REQUIRED
1/8, 5/16 Allen(hex) wrench
Loctite #271 thread locking adhesive
oxyacetylene
torch
GENERAL: Occasional replacement of hose gaskets is recommended. Replace
GASKET GRABBER [13c or 3b] if severe impact has caused damage. Coupling
service kits which include all hardware and Loctite® #271 are available for all stan-
dard 1.5” or 2.5” couplings. Special confi gurations or model changes to a nozzle
can be made by selecting the desired coupling or base. Couplings with special
or standard threads are interchangeable and may be exchanged on new nozzles.
Please specify desired threads when ordering.
COUPLING AND BLITZ BASE REMOVAL: All couplings and blitz bases are re-
tained with a ball race and set screw. Heat and then remove the ¼”-28 SOCKET
SET SCREW [5c, or 1b] from the coupling using a 1/8” Allen wrench. Turn coupling
so that hole faces down and rotate coupling back and forth to allow 3/16” STAIN-
LESS STEEL BALLS [4b, 15c or 5b] to drop out. When all the balls are out of the
groove, the coupling can be removed. Remove GASKET GRABBER/ debris screen
[13c, or 3b] from the coupling.
NOTE: On couplings [6c, 9c, 11c and 12c] and Base [2b], O-RING 141 [14c and
4b] will be found adjacent to the GASKET GRABBER [13c, or 3b]. On coupling [2c],
O-RING 151 [3c] is used. Replace and grease the proper O-Ring before installing
the coupling.
COUPLING AND BLITZ BASE INSTALLATION: Insert the GASKET GRABBER/
debris screen [13c, or 3b] into the coupling, raised end pointing toward the front of
the nozzle. Put the coupling onto the mating part and load the correct number of
balls into the ball groove (SEE PARTS LIST ON EXPLODED VIEW OF NOZZLE
TO DETERMINE CORRECT NUMBER OF STAINLESS STEEL BALLS [4c, 15b
or 5b] FOR YOUR COUPLING). Insertion of the balls is easier if the coupling is ro-
tated slightly back and forth as the balls are loaded. Apply Loctite® #271 and install
proper ¼”-28 SOCKET SET SCREW [5c, or 1b]. The set screw should be fl ush with
the surface of the coupling. If the coupling is diffi cult to turn, or feels rough when
turned, the set screw is in too far. Back set screw off a turn or so and try again. If the
feel is still not correct, recheck the number of balls in the coupling. On TIP ONLY
COUPLINGS and BLITZ BASES run the screw into the slot on the ball groove until
it bottoms out without applying pressure.
TIP ONLY BASE SERVICE: The TIP ONLY BASE [8b] is attached to the TIP ONLY
BARREL ASSEMBLY [7f ] by a threaded joint which is retained by Loctite® #271.
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 [8b]
can now be unscrewed. Remove and replace O-RING 143 [9b]. Clean all threads,
apply Loctite® #271 to threads and screw together.
TWIST TYPE VALVE SERVICE PROCEDURE
STO SLEEVE SERVICE: To remove the STO SLEEVE [14b], fi rst heat and remove
the CAM SCREWS [15b] and DETENT SCREWS [16b]. The detent screws contain
SPRINGS [18b] and BALLS [17b]. Then, STO SLEEVE [14b] can be slid off. Ser-
vice to interior STO valve should be done prior to reinstalling STO sleeve. Inspect
O-RINGS [19b] and replace if damaged. Installation is reverse of removal. Before
reassembly, grease O-Rings. Clean screw threads and apply Loctite® #271.
STO VALVE SERVICE: Heat the back end of the STO BASE [20b] with a torch and
unscrew the STO TAIL PIECE [11b]. The STO SLIDER [13b] may now be removed.
Inspect and replace any damaged O-RINGS [9b, and 12b]. Grease O-Rings, clean
threads and use Loctite® #271 upon reassembly. Refer to SLIDE VALVE SERVICE
PROCEDURE for Valve Plug Replacement, Valve Shutoff Adjustment, and Valve
Adjustment for Severe Cold.
