BOLT-ON PISTOL GRIP REMOVAL: PISTOLGRIP[19v]isheld on by a SOCKET
HEAD CAP SCREW [21v]. Remove screw with a 5/16” Ball DriverAllen wrench. To
reinstall, clean thread and apply Loctite® #271. Tighten screw to 95 in-lbs.
VALVE PLUG REPLACEMENT: Afterremoving back end, VALVE PLUG [17v,10b,
or 24b] is removed by pulling straight back. New valve plug can be installed using
a mallet.
VALVE SHUTOFF ADJUSTMENT: Shutoff valve is adjusted by the threads be-
tween the valve body and the front end of the nozzle. While holding the VALVE
HANDLE [3v]against stops intheOFF position, screwfrontendinto thevalvebody
until contact is made with the VALVE PLUG [17v]. Open handle to ON position to
remove contact. Screw the front end in 1/12 turn further to give the valve shutoff
compression. Thread in both SET SCREWS [12v] until they bottom out, without
applyingpressure.Inanalternatingfashioncontinueturninginsetscrewsuntil tight.
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 for
complete shut off during warm weather as stated above.
SLIDE VALVE DISASSEMBLY SEQUENCE
HANDLE REMOVAL: Remove both BUTTON HEAD CAP SCREWS [6v] from
VALVE HANDLE [3v] using a 7/32” Allen wrench. Slide CAM and SAFETY PINS
[4v and 5v] out of handle by gently prying about 3/8” apart the handle and the valve
body using a flat screw driver. To remove the handle, pull upwards while containing
theDETENTBALLS [7v] and SPRINGS [8v] toprevent their loss. Service to interior
valve parts should be done prior to reinstalling handle.
SLIDER AND SEAL REMOVAL: Remove #10-32 x ¼” SOCKET SET SCREWS
[12v] from the VALVE ASSEMBLY [11v] using a 3/32” Allen wrench. Unscrew front
portion of nozzle from valve. SLIDER [15v] can now be pulled out from the front of
valve. Remove and inspect O-RINGS [13v, 14v and 16v]. Replace O-Rings if they
are damaged.
SLIDE VALVE ASSEMBLY SEQUENCE
SLIDER AND SEAL INSTALLATION: Insert O-RINGS [13v, 14v and 16v] into
the proper grooves in the valve body. Check SLIDER [15v] for any raised metal at
groove area. Replace if necessary. Lubricate O-Rings and slider with DOW #112
Lube. Push slider into the valve body.
HANDLE INSTALLATION: Insert DETENT SPRINGS [8v] and DETENT BALLS
[7v] into the handle lugs. While holding balls in place, snap the HANDLE [3v] into
placewithoffsetholes FORWARD.Carefully align thegrooveonSLIDER[15v]with
offset hole in VALVE DISCS [9v] and with offset hole in handle. Slide SAFETYPIN
[5v] into offset hole in handle. Push down into engagement with groove in slider,
until head of pin is flush with handle. Repeat procedure for CAM PIN [4v]. Insert
BUTTON HEAD SCREWS [6v] through the lower handle holes. Thread each into
corresponding center trunnion hole. Tighten HANDLE SCREWS [6v] securely with
atorquevalueof100in-lbs(11.3N m). Handle should click firmlyand smoothly into
all detent positions and the slider should move back and forth smoothly. The force
to move handle should be between 5 lbs and 13 lbs applied at top center of handle.
FRONT END
SHELL SERVICE PROCEDURE
SHAPER REMOVAL: The rubber bumper is permanently bonded onto the stream
shaper as a single unit referred to as the SHAPER [10f]. The shaper is attached
to the SHAPER GUIDE [4f, or 5f] by a threaded joint that is retained by Loctite®
#271. Grip rear portion of the nozzle in a vise with padded jaws, or clamp SHAPER
GUIDE [4f, or 5f] using TFT special tool TH502 held in a vise. Direct a hot narrow
flamearound the rear portion ofthe shaper and heatfor approximately 20seconds.
Damage to BUMPER [10f] and LABELS [1f, 2f, or 6f] can be reduced by protecting
them with a wet cloth. Use a strap wrench to unscrew the shaper from the shaper
guide. Remove the shaper. Inside the shaper are (48) 13/16”ACETALBALLS [8f],
some of which may fall free as the Shaper is removed. If Shaper is to be reused,
clean ball track and replace 336 O-RING [9f] if damaged.
SERVICE TO CAM GROOVES AND BALLS: When Shaper is removed, check
to see if the stream shaping GUIDE BALLS [3f] and CAM GROOVES [7f - part of
BARRELCONE ASSEMBLY] are damaged. Replace Balls if sheared or missing. If
the CAM GROOVES are badly damaged, the BARREL CONE ASSEMBLY should
also be replaced.
BARREL CONE ASSEMBLY SERVICE: This assembly is permanent and cannot
be taken apart. Check to ensure that the flush spring is not damaged by pushing
down on the Barrel Cone with both hands (about 50 lbs force). The Barrel Cone
AssemblyshouldbereplacediftheBarrel Cone does not push down or spring back
up by itself. Lightly grease the CAM GROOVES before re-installing the SHAPER
GUIDE.
SHAPER INSTALLATION: Install 336 O-RING [9f] in front groove of SHAPER
[10f]. Grease the seal and ball groove heavily. Place (48) 13/16” ACETAL BALLS
[8f] into greased ball groove. Apply Loctite® #271 to male thread on SHAPER
GUIDE[4f, or5f].StartshaperontoSHAPERGUIDEthreads. PlacethreeSHAPER
GUIDE BALLS [3f] into the grooves on barrel and screw down shaper until threads
bottom out.
PRESSURE CONTROL SERVICE PROCEDURE
Tools Required:
1/4Allen wrench (10” Long)
1/4Allen wrench (regular length)
Mallet
PRESSURE CONTROL REPLACEMENT: The pressure control may be removed
and replaced as a unit by following the procedure in the PRESSURE CONTROL
REMOVALand INSTALLATION AND INITIALOPENINGADJUSTMENT sections.
NOTICE: The Pressure Control Unit is part of the BARREL ASSEMBLY [7f]. This
unitisfactorycalibratedandsealed.Serviceonthisunitisbestperformedatthefac-
tory using special tooling and equipment. In the unlikely event that this unit should
need service, it is highly recommended that you return the complete nozzle to the
factory for repairs OR replace the entire PRESSURE CONTROL UNIT. DO NOT

willassume NO liability for damage orinjury resulting fromattempts to disassemble
or repair the Pressure Control Unit.
PRESSURE CONTROL REMOVAL: To remove the CONTROLUNIT first separate
the front end from the nozzle, then remove the VALVE PLUG (106, 24b or 17v).
Loosen and remove the shaft locking SCREW (1p) with a 3/16 allen wrench. Insert
a 7/32Allen wrench into the front of the shaft and screw the shaft out of the barrel
assembly. LOCKING SLEEVE (2p) is removed by pushing it forward and out of
BARRELASSEMBLY (7f) with a punch. Note: LOCKING SLEEVE may require light
tapping with a hammer to remove.
PRESSURE CONTROL INSTALLATIONAND INITIAL OPENING ADJUSTMENT:
To install the CONTROL UNIT, lightly grease I.D. and O.D. of locking sleeve and
also threads of the screw. Place LOCKING SLEEVE (2p) with hollow end forward
onto back of shaft, thread finger tight. Note: If old LOCKING SLEEVE is reused it
may require light tapping with a hammer and punch to install. Screw CONTROL
UNIT (with pressure control parts installed) into barrel assembly. Insert a 7/32 Allen
wrench into front of shaft and turn in until baffle just touches BARREL CONE (7f)
then turn back between ½ and 3/4 of a turn (opening gap of .026/.036 inches or
.66/.91mm).KeepAllenwrench in shaft to assure that shaft doesn’t turn and tighten
screw against locking sleeve, to approximately 180 in-lbs.
IMPORTANT: Always flow test after adjusting. Nozzle pressure and flow require-
ments are shown on the following table:

DUAL-FORCE KNOB REMOVAL: To remove the DUAL-FORCE KNOB [8p] from
the BAFFLE [4p]:
1) Turn knob to standard setting.
2) Turn the SHAPER [10f] back to full flush.
3) Insert a small probe (such as a 1/16” drill bit) into the smaller of the two holes on
top of the knob.
4) Simultaneously push down with probe while turning knob clockwise (when
viewed from the front). Once knob turns a little, the probe may be removed.
5) Turn knob clockwise until it hits a stop. (about 25 degrees).
6) Pull knob to remove from baffle.
