sion sleeve system, size). The connection could be useless and the machine
and expanding heads could be damaged.

3. Operation

3.1. Radial presses (Figs. 1 to 6 and 16 to 19)
A test pressing with inserted press fitting must be made with the drive machine
and the respectively inserted pressing tong, pressing tong Mini, pressing ring
with adapter tong before every use. The pressing tong (1), pressing ring (20)
or pressing segments (21) must close fully. Full closure of the pressing jaws
(10), pressing rings (20) or pressing formers (21) both at their tips (Fig. 1, and
Fig. 16 to 19 at "A") and on the opposite side (Fig. 1 and Fig. 16 to 19 at "B")
can be observed after completing the pressing. Check the tightness of the
connection (observe national specifications, standards, regulations, etc.)
The pressing tong, pressing tong Mini, pressing ring and adapter tong, and
especially the pressing contour (11 / 22) of both pressing jaws (10) or all 3
pressing segments must be checked for damage and wear before every use.
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings or adapter
tongs may no longer be used. There is otherwise a risk of incorrect pressing
or accidents.
If during closing of the pressing tongs, pressing tongs Mini or pressing rings a
marked ridge is created on the compression sleeve, the pressing may be
defective or not tight (see 5. Trouble).
For preventing damages make sure to avoid operating situations like exempla-
rily shown in Fig. 13 through 15, that no distortion between pressing tongs,
pressing tongs Mini, pressing rings, adapter tongs, fitting and drive unit occurs.
3.1.1. Working procedure
Press the pressing tongs, pressing tongs Mini (1) together manually until they
can be pushed over the press fitting. Always position the drive unit with the
pressing t ongs on the press fitting at right angles to the pipe axis. Release the
pressing tongs so that they close around the press fitting. Hold the drive unit
by the housing grip (6) and the pistol grip (9).
Place the pressing ring (20) around the pressing fitting. Insert the pressing tong
(19) into the drive unit and lock the tong retaining bolt. Press the pressing tong
(19) together with your hand so that the adapter tong can be placed on the
pressing ring. Release the adapter tong so that the adapter tong is tightly applied
to the pressing ring and the pressing ring to the pressfitting.
In the case of the REMS Power-Press E, set the rotation direction lever (7) to
the right (advance) and press the inching switch (8). Keep the inching switch
(8) pressed until the pressing is finished and the pressing tong or pressing ring
is closed. Set the rotation direction lever (7) to the left (return) and press the
switch (8) until the press rollers have retracted and the slipping clutch r esponds.
Do not put unnecessary loads on the slipping clutch.
In the case of the REMS Power-Press and REMS Akku-Press, keep the inching
switch (8) pressed until the pressing is finished and the pressing tong or pressing
ring is completely closed. This is indicated by an acoustic signal (clicking).
Press the reset button (13) until the press r ollers (5) are fully retracted.
In the case of the REMS Mini-Press ACC, REMS Akku-Press ACC and REMS
Power-Press ACC, keep the inching switch (8) pressed until the pressing is
finished and the pressing tong or pressing ring is completely closed. After
completion of p ress i ng, the drive unit switches automati c ally to return (forced
return).
Press the pressing tongs together with your hand so that they can be removed
from the pressfitting together with the drive unit. Press the adapter tong together
with your hand so that they can be removed from the pressing ring together
with the drive unit. Open the pressing ring by hand so that it can be pulled off
the pressfitting.
3.1.2. Operating safety
In the case of the REMS Power-Press E, the pressing operation is ended by
releasing the inching switch (8). For the mechanical safety of the drive units,
a torque-controlled safety slipping clutch is operative in both end positions of
the press rollers.
The REMS Power-Press and REMS Akku-Press ends the pressing opera t ion
automatically, emitting an acoustic signal (clicking). The REMS Mini- P ress ACC,
REMS Akku-Press ACC and REMS Power-Press ACC ends the pressing
operation automatically, emitting an acoustic signal (clicking), and returns
automatically (forced movement).
NOTICE
A perfect pressing is only produced with full closure of the pressing tongs,
pressing tongs Mini, pressing ring or pressing segment. Full closure of
the pressing jaws (10), pressing rings (20) or pressing segment (21) both
at their tips (Fig. 1 and Fig. 16 to 19 at "A") and on the opposite side (Fig.
1 and Fig. 16 to 19 at "B") can be observed after completing the pressing.
If a visible burr is created on the pressing sleeve when closing the pressing
tongs, pressing tongs Mini, pressing ring or pressing segment, the pressing
may be faulty or leaking (see 5. Trouble).
3.1.3. Working safety
To ensure safe working, the drive units are equipped with a safety inching
switch. This permits immediate switching off of the drive units at any time,
particularly if a potential hazard arises. The drive units can be switched to the
return function in any position.
3.2. Axial presses (Figs. 6, 7, 10)
3.2.1. Pressing with the REMS Ax-Press 15 and REMS Ax-Press 40 (Fig. 6, 7)
Place the preassembled compression sleeve fitting inside the pressing heads
(14). Hold the drive unit by the housing grip (6) and the pistol grip (9), and keep
the inching switch (8) pressed until the compression sleeve is in contact with
the collar of the compression sleeve fitting. This is also indicated by an acoustic
s ignal (clicking). Press the reset button (13) until the pressing heads (14) are
f ully retracted.
If there is a noticeable gap between the compression sleeve and the collar of
the compression sleeve connector after closing the compression heads, the
pressing may be faulty or leaking (see 5. Faults). Read and follow the installa-
tion and assembly instructions of the system manufacturer.
Pressing with REMS Ax-Press 25 ACC, REMS Ax-Press 25 L ACC (Fig. 10)
Note the different working range of the axial presses. The respective latest
sales literature applies. Note that the compression heads must be inserted into
the pressing machine in such a way that the pressing can be done in one stroke
if possible. This is not possible in some cases and pre-pressing and finish
pressing is necessary. For this, one compression head or both compression
heads must be inserted turned 180° before the second pressing process so
that they are closer together. In the REMS Ax-Press 25 L ACC the closer
distance may have to be reached by moving the outer compression head to
the middle compression head position. Read and follow the installation and
assembly instructions of the system manufacturer.
Insert preassembled compression sleeve joint into the compression heads (14).
Hold the drive machine either with one hand on the switch handle (9) or two
hands on the housing handle (6) and the switch handle (9). Keep the inching
switch (8) pressed until the compression sleeve is touching the collar of the
compression sleeve connector. The drive machine then switches automatically
to return (forced return).
If there is a noticeable gap between the compression sleeve and the collar of
the compression sleeve connector after closing the compression heads, the
pressing may be faulty or leaking (see 5. Faults). Read and follow the installa-
tion and assembly instructions of the system manufacturer.
With the compression sleeve system IV, various pressing heads are needed
for one pipe size. Consult and comply with the instructions for installation and
fitting of the system's manufacturer.
CAUTION
Danger of cru shing! Keep your hands away from the moving pressing
heads (14)!
3.2.2. Expansion with REMS Ax-Press 15 (Fig. 6)
Push the compression sleeve over the pipe, insert the expanding head as far
as it will go into the pipe, and press the expanding head/drive unit against the
pipe. Switch on the drive unit (8). Ensure that the compres s ion sleeve has
during the expansion process sufficient clearance from the expanding head,
otherwise the expanding jaws (17) might become bent or broken. Hold down
the inching switch (8) until the pipe has been expanded. This is also indicated
by an acoustic signal (clicking). Press the reset button (13) until the expanding
head has closed again. If necessary repeat the expansion. Consult and comply
with the instructions for installation and fitting of the system's manufacturer.
3.3. REMS Akku-Ex-Press Q & E ACC, REMS Power-Ex-Press Q & E ACC
(Fig. 8)
Consult and comply with the instructions for installation and fitting of the system's
manufacturer. Slide a Q & E ring of appropriate size onto the p ipe. Insert the
expansion head into the pipe and press the expanding h ead/drive unit against
the pipe. Switch on the drive unit (8). When the expanding head is opened, the
drive unit switches automatically to return and the expanding head is closed
again. Keep holding the inching switch (8) down in the REMS Akku-Ex-Press
Q & E ACC and push the expanding head/drive unit further. Turn the pipe
slightly. Keep repeating the expansion process until the expanding jaws (17)
are slid all the way into the pipe. Release the inching switch (8) after every
expanding process in the REMS Power-Ex-Press Q & E ACC, wait until the
expanding mandrel has moved back completely and then press the inching
switch (8) again. Repeat the expanding process until the expanding jaws (17)
are pushed into the pipe up to the stop.
Expanding with REMS Akku-Ex-Press P ACC, REMS Akku-Ex-Press Cu
ACC (Fig. 11, 12)
Push the compression sleeve over the pipe in the REMS Akku-Ex-Press P
ACC, insert the expanding head into the pipe up to the stop and press the
expanding head/drive machine against the pipe. Switch on the drive machine
(8). Make sure that the compression sleeve is far enough away from the
expanding head in the expanding process because otherwise the expanding
jaws (17) can bend or break. Keep the inching switch (8) pressed until the pipe
is expanded. This is indicated by an acoustic signal (click). Expand several
times if necessary. Turn the pipe slightly. Read and follow the installation and
assembly instructions of the system manufacturer.
In the REMS Akku-Ex-Press Cu ACC, insert the expanding head into the pipe
up to the stop and press the expanding head/drive machine against the pipe.
Switch on the drive machine. If the expanding head is open, the drive machine
switches automatically to return and the expanding head is closed again. Read
and follow the installation and assembly instructions of the system manufacturer.
