pressing tongs, Mini pressing tongs (Fig. 1), the (PR-3B) pressing ring
(Fig. 20) and the 45° (PR-2B) pressing ring (Fig. 21). After completing the
pressing, check that the pressing jaws (10) close fully at "A" and on the
opposite side "B" for the (4PZ-G) pressing tongs (Fig. 17) and the (PZ-S)
pressing tongs (Fig. 18). After completing the pressing, check that the
pressing segments (21) close fully at "A" and on the opposite side "B"
for the (PR-3S) pressing ring (Fig. 19) and the XL (PR-3S) pressing ring.
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. 12, 13)
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.

3.4. Machine status check with fl at battery protection
All REMS cordless presses are available as of 2011-01-01 with an electronic
machine status check with charging state display (23) by a 2-coloured green/
red LED. The LED lights green when the battery is fully or still suffi ciently
charged. The LED lights red when the battery must be charged. If this condition
occurs during pressing and the pressing process is not fi nished, 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 fl ashes red, the battery must be recharged.
3.6. Pressure monitoring, REMS Akku-Press 22 V ACC (Fig. 4)
The pressure is monitored during pressing in the REMS Akku-Press 22 V ACC.
Upon completion of the pressing process, the pressure indicator LED (28) lights
white if the pressure is within the specifi cation. If this lights red, the pressure was
less than specifi ed. If it lights red and the drive unit is switched off, the pressure
was greater than specifi ed. Hold the reset button (13) until the pressing rollers
have moved back completely. If the pressure was out of specifi cation, a new
pressing process can be started and the pressure indicator LED then lights white
again during the pressing process. After a dwell time of approx. 2 minutes, the
LED goes out but lights up again when the drive unit is switched back on. If
the pressure indicator LED lights red, it is recommended to have the drive unit
checked/repaired by an authorised REMS customer service workshop.
NOTICE
If the pressure is within the specifi cation and the pressure indicator LED (28)
lights white, it cannot always be assumed that the pressing tongs, the pressing
ring and the pressing segments were closed at the end of the pressing process.
Always check full closure in every pressing process, see 3.1.
3.7. Power supply unit (accessory art. no. 571535, 571565, 571567, 571578)
The power supply units are intended for mains operation of the cordless tools
in place of the battery. See the guidelines for use (Fig. 22) for the intended
use. The power supply units are equipped with overvoltage and temperature
protection. The operating state is indicated by a LED. A lit LED indicates that the
device is ready for operation. If the LED goes out or fl ashes, this indicates an
overcurrent or impermissible temperature. The drive unit cannot be used during
this time. After a dwell time, the LED lights again and work can be continued.
NOTICE
The power supply units are not suitable for outdoor use.
