3. Conguration
In addition to the standard tool, the FireRex®C-WT blind rivet nut setting tool is equipped
with sensors for recording the setting force and setting stroke during the setting process. A
process data module is integrated into the head housing of the blind rivet nut setting tool that
evaluates the recorded process data. The process evaluation is visualised on the blind rivet
nut setting tool by means of an LED integrated into the housing. The sensors employed in the
blind rivet nut setting tool and the process data module are maintenance-free. Figure 1 shows
thecongurationoftheFireRex®C-WT with setting process monitoring.

4. Starting procedure
Prior to operating the blind rivet nut setting tool, attach the relevant threaded mandrel with
nosepiece to match the thread size.
Before starting the blind rivet nut setting tool, read and observe the operating instructions and
safety information and keep in a safe place. Have the compressed air mains connection to the
blindrivetnutsettingtoolmadeaqualiedperson.Initialcommissioningmustalsobecarried
out together with a service technician from GESIPA®. For editing of the blind rivet nut setting
tool, it must be connected to a PC with Windows 7 or higher using the GESIPA®GrivCheck
2.0 software and a USB adapter cable (Article No. 1435512).
3.2 Process data evaluation
The setting process is monitored on the FireRex®by evaluating the setting force and setting
stroke during the setting process in the material to be joined. The evaluation criteria are the
maximum setting force Fm and the setting stroke Sm up to standstill. A blind rivet nut joint is
evaluatedasOKwhenthisvaluepairiswithinadenedevaluationwindow.Ifthevaluepair
liesoutsidethiswindow,orleavesthewindowtothepreviouslydenedside,theprocessis
evaluated as NOK.

4.2 How to change a threaded mandrel
• Disconnect the blind rivet nut setting tool from the compressed air network.
• Detach locknut A, using double open-end spanner SW.
• Unscrew nosepiece B with locknut A
• PushslideKbackallthewaytobu󰀨erandholdtight
• Unscrew threaded mandrel C
• Insert new threaded mandrel C of same size (if worn out) or threaded mandrel C of match-
ingthreadsizeallthewaytobu󰀨er.
• Release slide. At the same time make sure that the threaded mandrel C is locked safely
inside the hexagon socket of the slide. If required, unscrew threaded mandrel C slightly
until the slide F locks.
• Insert a matching nosepiece B for each thread size using locknut A and lock loosely with
locknut, using a double open-ended spanner.
• Set threaded mandrel length "X", as described under item 4.3.
4.3 How to set threaded mandrel length "X"
• Detach locknut A, using double open-end spanner.
• Adjust threaded mandrel length "X", according to nut length (see image 3) by turning
nosepiece B.
• Make full use of depth of thread for closed blind rivet nuts (image 3).
• Secure nosepiece B using locknut A.
The FireRex®C-WT is adjusted to a setting force suitable for the respective blind rivet nut size
(e.g. M6). This ensures that all blind rivet nuts of certain thread dimensions (e.g. M6x15.5 or M6x18)
butwithdi󰀨eringnutlengthsarealwayssetpreciselyasintendedintomaterialsofvaryingthicknesses.
5. How to adjust the setting force
4.1 Oiler
• To prolong the service life of the pneumatic motor, it should be lubricated by operating the FireRex®
C-WT blind rivet nut setting tool with oiled air.
• Thelubricatormayonlybeintegratedinline6(twisto󰀨).
• The original GESIPA®oil can be used for lubrication.
• The oiler should be set such that approx. 1 drop of oil is added to the compressed air every 300-
350settingoperations.Onellingofthesuppliedoileristhereforesu󰀩cientfor600,000-700,000
setting operations.
• Analoilvolumehastobedeterminedoveraprolongedperiodofoperation.Payattentioninparti-
cular here whether, e.g. oil droplets stick to the device. In this case the oil volume has to be reduced.

GB
1638027 Operating manual FireRex®C-WT
Turning in setscrew G increases the setting force of the rivet tool; unscrewing decreases
the setting force!
To adjust the setting force, follow the sequence of operations below:
1. The setting force can be pre-set using the enclosed colour code chart. The right colour code
can be selected on the colour code chart according to the nut sizes and the nut materials
(e.g. M6 – steel Colour code red)
2. Using the enclosed hexagon screw driver SW 4, turn the set screw with colour scale Ito the
selected colour code in the display window.
3. Winding down the blind rivet nut to be set (see item 6.1). Insert the blind rivet nut into the mate-
rial to be riveted. For materials of varying thicknesses it is advisable to select maximum
material thickness.
4. Triggering of a setting operation by driving the solenoid valves (1.1 and 1.2). Then check the
nut you have set:
• The process can be monitored visually or in the GrivCheck 2.0 software.
• Ifthenutisnotsu󰀩cientlydeformedduringthisprocess,usethehexagonscrewdriver
SW 3 to screw in the set screw with colour scale Gby c. 0.5 rotations. Then repeat the
setting sequence with a new nut and check once again.
• Ifthenutbecomestoodeformed(e.g.di󰀩culttoremove;nutthreaddeformed),the
set screw Gshould be unscrewed about 1 rotation. Then repeat the setting sequence with
a new nut and check once again.

6.2 How to set the blind rivet nut
• Insert the wound down blind rivet nut all the way into the drilled hole of the work piece.
• Start the setting process by venting the solenoid valves (1.1 and 1.2)
• Whenthesetsettingforceisreached(seepoint5!),thethreadedmandrelmovesforward
again. The bead breaking process is started by driving solenoid valve (1.3).
• The solenoid valves should be controlled via a PLC supplied by the customer.
• If, for example, the solenoid valve is switched too early during a setting operation and the
threaded mandrel is therefore not retracted completely, or the nut was positioned crooked
during riveting, a bead breaking process can be started manually by driving solenoid valve
(1.3) again.
• If the threaded mandrel cannot be retracted by driving solenoid valve (1.3) (e.g. thread in
the nut deformed too much), the threaded mandrel can be retracted by hand. To do this,
insert the SW 3 Allen key into the socket D on the air outlet of the pneumatic motor (see
Figure 1) and turn in anti-clockwise direction to carefully release the threaded mandrel.
6.3 How to remove a nut manually by turning
The blind rivet nut setting tool must be kept in a dry place. Worn threaded mandrels must
be replaced as described under item 3.1, as required. After prolonged use it may become
necessary to top up or replace the hydraulic oil. The hydraulic oil should only be replaced by
qualiedpersonnel.
7. Maintenance and care
6. Sequence of operations
• Position blind rivet nut without tilting on threaded mandrel C.
• Then use the blind rivet nut setting tool to press the threaded mandrel C towards the rivet
tool. This action will automatically start the winding down process.
• Donotpressactivationbutton!
• Keep a tight hold of the blind rivet nut throughout the winding down process until the blind
rivetnutrestsonnosepieceB.Thewindingdownprocessnishesautomatically.
