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, fi tting and drive unit occurs. Failure to do so could lead to
fracture and fl ying parts can cause serious injuries.
3.1.1. W 3.1.1. Working procedure 3.1.1. Working procedure
Press the pressing tongs, pressing tongs Mini (1) together manually until they
can be pushed over the press fi tting. Always position the drive unit with the
pressing tongs on the press fi tting at right angles to the pipe axis. Release the
pressing tongs so that they close around the press fi tting. Hold the drive unit
by the housing grip (6) and the pistol grip (9).
Place the pressing ring (20) around the pressing fi tting. Insert the adapter tongs/
Mini adapter tongs (19) into the drive unit and lock the tong retainer bolt, posi-
tion the rotary sleeve (27) if necessary, see 2.2. 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 fi rmly on the cylinder rollers/ball sockets of the
pressing ring and the pressing ring on the press fi tting. 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 fi nished 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 immediately
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 fi nished 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, EMS Mini-Press ACC, REMS Mini-Press 22 V ACC,
Mini-Press S 22 V ACC, REMS Akku-Press ACC, REMS Power-Press ACC REMS Akku-Press ACC, REMS Power-Press ACC
and REMS Power-Press XL ACC, keep the safety inching switch (8) pressed
until the pressing is fi nished 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).
Press the pressing tongs, pressing tongs Mini together with your hand so that
they can be removed from the pressfi tting 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 pressfi tting.
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 Mini- Press ACC 22 V, REMS Mini- Press ACC, REMS Mini- Press ACC 22 V, REMS Mini-Press S
22 V ACC, REMS Akku-Press ACC, REMS Power-Press ACC and REMS REMS Akku-Press ACC, REMS Power-Press ACC and REMS
Power-Press XL 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. 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.
3.2. Axial presses (Figs. 10, 11)
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 fi nish
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.
