(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 Mini-Press 22 V 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 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).
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
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 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. 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 / 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. REMS Ax-Press 30: Upon completion of the pressing,
the drive unit switches over automatically to return (forced switch-off). This is
indicated by an acoustic signal (click). REMS Ax-Press 40: Hold the reset button
(13) until the pressing heads (14) have moved back completely.
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)!

3.4. Battery charging status check with complete discharge protection
All REMS cordless presses made as of 2011-01-01 are equipped with an
electronic battery charging status check with battery charge indication by a
2-coloured green/red LED (23). The LED lights green when the battery is fully
or still sufficiently charged. The LED lights red when the battery must be charged.
If this condition occurs during pressing and the pressing process is not finished,
the pressing must be completed with a fully charged Li-Ion battery. If the drive
unit is not used, the LED goes out after approx. 2 hours but comes on again
when the drive unit is switched back on.
3.5. Graduated charging level indicator (26) of the Li-Ion 21.6 V battery
The graduated charging level indicator shows the charging level of the battery
with 4 LEDs. At least one LED lights for a few seconds after pressing the key
with the battery symbol. The more LEDs that light green, the higher the charging
level of the battery. If a LED flashes red, the battery must be recharged.
