3.1. Radial presses (Figs. 1 to 5 and 15 to 19)
The pressing tongs, Mini pressing tongs, pressing ring, adapter tongs and Mini
adapter tongs, especially the pressing contour (11, 22) of the pressing jaws
(10) or all 3 pressing segments (21) must be checked for damage and wear
before every use. Damaged or worn pressing tongs, Mini pressing tongs,
pressing rings, adapter tongs and Mini 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 or Mini adapter tongs before every use.
The pressing tongs, Mini pressing tongs (1), the pressing ring (20) with adapter
tongs or Mini 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. 15 to 19 at "A") and on the opposite side (Fig. 1 and Fig. 15 to
19 at "B"). Check the tightness of the connection (observe national specifica-
tions, 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. 12 through 14, that no distortion between
pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini, 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 adapter tongs/
Mini adapter tongs (19) into the drive unit and lock the tongs retaining bolt.
Press the adapter tongs/Mini adapter tongs (19) together with your hand so
that the adapter tongs/Mini adapter tongs can be placed on the pressing ring.
Release the adapter tongs/Mini adapter tongs so that the radii/hemispheres of
the adapter tongs/Mini adapter tongs lie firmly on the cylinder rollers/ball sockets
of the pressing ring and the pressing ring on the press fitting. With adapter
tongs Z1 and Mini adapter tongs Z1, please note that the pressing ring may
only be applied below 45°.
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 rota-
tion 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, the pressing ring 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 tongs
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 tongs 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).
On REMS Mini-Press 22 V ACC, keep the inching switch (26) pressed until the
Mini pressing tongs or the pressing ring are fully closed. Upon completion of
the pressing, the drive unit switches over automatically to return and then
switches off (forced switch-off). This is indicated by an acoustic signal (click).
The inching switch can be released whilst the force in the pressing process
increases and the pressing process will still be completed. The pressing process
can be interrupted at any time by pressing the emergency off key (27).
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 tongs, adapter tongs Mini 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
18
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).
REMS Mini Press 22 V ACC ends the pressing process automatically and emits
an acoustic signal (click), returns automatically (forced return) and then switches
off.
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. 15 to 19 at "A") and on the opposite side (Fig.
1 and Fig. 15 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
(8). This permits immediate switching off of the drive units at any time, particu-
larly if a potential hazard arises. The drive units can be switched to the return
function in any position. REMS Mini-Press 22 V ACC is fitted with an emergency
off key (27). This enables immediate return and shut-down of the drive unit
especially in the event of danger.
3.2. Axial presses (Figs. 6, 9)
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 Ax­Press 40 (Fig. 6)
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 s hing! Keep your hands away from the moving pressing
heads (14)!
3.2.2. REMS Ax­Press 25 ACC, REMS Ax­Press 25 L ACC (Fig. 9)
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 s hing! Keep your hands away from the moving pressing
heads (14)!
