Only use system-specific expanding heads. Expanding heads are labelled with
letters to identify the compression sleeve system and with a number to identify
the size. Read and observe the installation and assembly instructions of the
manufacturer/supplier of the used system. Never expand with the wrong
expanding heads (compression sleeve system, size). The connection could be
useless and the machine and expanding heads could be damaged.
NOTICE
Make sure that the compression sleeve is far enough away from the expanding
head (16) in the expanding process because otherwise the expanding jaws
(17) can bend or break.

3. Operation

3.1. Radial presses (Figs. 1 to 4 and 14 to 17)
The pressing tongs, Mini pressing tongs, pressing ring and adapter tongs,
especially the pressing contour (11, 22) of the pressing jaws (10) or all 3 pressing
segments must be checked for damage and wear before every use. Damaged
or worn pressing tongs, Mini pressing tongs, pressing rings and adapter tongs
may no longer be used. There is otherwise a risk of incorrect pressing or
accidents.
A trial pressing with inserted press fitting must be made with the drive unit and
the respectively used pressing tongs, Mini pressing tongs and the respectively
used pressing ring with adapter tongs before every use. The pressing tongs,
Mini pressing tongs (1), the pressing ring (20) with adapter tongs must fit into
the drive unit mechanically and be properly lockable. After completing the
pressing check that the pressing jaws (10), pressing rings (20), pressing
segments (21) close fully both at their tip (Fig. 1 and Fig. 14 to 17 at "A") and
on the opposite side (Fig. 1 and Fig. 14 to 17 at "B"). Check the tightness of
the connection (observe national specifications, standards, regulations, etc.)
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).
CAUTION
For preventing damages make sure to avoid operating situations like
exemplarily shown in Fig. 13 through 15, that no distortion between
pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, fitting
and drive unit occurs. Failure to do so could lead to fracture and flying
parts can cause serious injuries.
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 tongs 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 adaptor tongs so that the radii of the adaptor tongs
lie firmly on the cylinder rollers of the pressing ring and the pressing ring on
the pressfitting.
On REMS Power-Press SE push the rotation direction lever (7) to the right (feed)
and press the safety inching switch (8). Keep the safety inching switch (8) pressed
until the pressing is finished and the pressing tongs or pressing ring are closed.
Release the safety inching switch immediately. Push the rotation direction lever
(7) to the left (return) and press the switch (8) until the press rollers have moved
back and the safety slip clutch responds. Release the safety inching switch
immediately.
NOTICE
Do not needlessly stress the safety slip clutch. Release the safety inching switch
immediately after closing the pressing tongs or moving back the pressing rollers.
The safety slip clutch is subject to normal wear like any slip clutch. However,
if it is needlessly stressed, it wears more quickly and can be destroyed.
In the case of the REMS Power-Press and REMS Akku-Press, keep the safety
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 rollers (5) are fully retracted.
In the case of the REMS Mini-Press ACC, REMS Akku-Press ACC and REMS
Power-Press ACC, keep the safety inching switch (8) pressed until the pressing
is finished and the pressing tong or pressing ring is completely closed. After
completion of press ing, the drive unit switches automati cally to return (forced
return). This is indicated by an acoustic signal (click).
Press the pressing tongs, pressing tongs Mini 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
On REMS Power-Press SE the pressing process is ended by releasing the
safety inching switch (8). A torque-dependent safety slip clutch acts additionally
in both end positions of the press rollers for the mechanical safety of the drive
units. Do not needlessly stress the safety slip clutch. REMS Power-Press SE
is equipped with an electronic safety circuit which protects the drive unit against
overloading. The drive unit can be used again afterwards as a rule unless the
electronic safety circuit switches the drive unit off repeatedly at the end of the
pressing. In this case the drive unit must be inspected/repaired by an authorised
REMS customer service workshop. However, if the drive unit switches off before
pressing is completed, the drive unit must be inspected/repaired immediately
by an authorised REMS customer service workshop.
The REMS Power-Press and REMS Akku-Press ends the pressing opera tion
automatically, emitting an acoustic signal (clicking).
The REMS Mini- Press 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. 14 to 17 at "A") and on the opposite side (Fig.
1 and Fig. 14 to 17 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. 5, 8)
Note the different working range of the axial presses. The respectively latest
REMS sales literature applies, see also www.rems.de → Downloads → Product
Catalogues, Brochures. Make sure that the pressing heads (14) are inserted
into the drive unit in such a way that the pressing can be made in one stroke
if possible. This is not possible in some cases and pre-pressing and finish
pressing is necessary. For this, one pressing head or both pressing heads must
be inserted turned 180° before the second pressing process so that they are
closer together.
3.2.1. REMS Ax-Press 40 (Fig. 5)
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 safety 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 signal (clicking). Press the reset button (13) until the pressing heads
(14) are fully 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 observe the instal-
lation and assembly instructions of the manufacturer/supplier of the pressing
sleeve system to be pressed.
CAUTION
Danger of cru shing! Keep your hands away from the moving pressing
heads (14)!
3.2.2. REMS Ax-Press 25 ACC, REMS Ax-Press 25 L ACC (Fig. 8)
Insert the pre-assembled pressing sleeve fitting into the pressing heads (14).
On the REMS Ax-Press 25 L ACC the closer distance of the pressing heads
may have to be achieved by moving the outer pressing head into the centre
pressing head position. 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 safety 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 observe the instal-
lation and assembly instructions of the manufacturer/supplier of the pressing
sleeve system to be pressed.
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)!
3.3. Pipe expanders
3.3.1. REMS Akku-Ex-Press Q & E ACC, REMS Power-Ex-Press Q & E ACC
(Fig. 6, 7)
Read and observe the installation and assembly instructions of the manufacturer/
supplier of the used system. Slide a Q & E ring of appropriate size onto the
pipe. Insert the expansion head into the pipe and press the expanding head/
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 safety 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 safety 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.
