Roller Akku-Exparo 22 V ACC, Instruction Manual, Page: 21 / 92

CAUTION 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. 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. Press the adapter tongs/Mini
adapter tongs (18) 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°.
NOTICE
Only use the adapter tongs approved for the pressing ring, see 2.2. Failure to
do so can lead to faulty or leaking pressings and could also damage the pressing
ring or adapter tongs.
On ROLLER’S Uni-Press SE push the rotation direction lever (7) to the right

(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 rollers have moved back and the safety sli rollers have moved back and the safety sli
inching switch immediately.
NOTICE
Do not needlessly stress the safety slip clutch. Release the safety inching switch
immediately immediately after closing the pressing tongs, the pressing ring or moving back immediately 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 ROLLER’S Uni-Press and ROLLER’S Multi-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.

ACC and ROLLER’S Uni-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).
On ROLLER’S Multi-Press 22 V ACC, keep the safety inching switch (8) pressed
until the pressing tongs or the pressing ring are fully closed. Upon completion
of the pressing, the drive unit switches over automatically to retraction (automatic
circuit control). The coloured LED of the pressure indicator (28) indicates
whether the pressure of the drive unit was within the specifi cation, see 3.6.
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 ROLLER’S Uni-Press SE ROLLER’S Uni-Press ROLLER’S Uni-Press the pressing process is ended by releasing the SE SE
safety inching switch (8). A torque-dependent safety slip clutch acts in both end
positions of the press rollers for the mechanical safety of the drive unit. Do not
needlessly stress the safety slip clutch! ROLLER’S Uni-Press SE is also equipped
with an electronic safety circuit which switches off the drive unit at high load.
As long as the pressing tongs (1), pressing rings (20) close fully, see 3.1, this
is uncritical. However, if the drive unit switches off before pressing is completed
(pressing tongs, pressing rings were not closed, see 3.1), work must not continue
and the drive unit must be inspected/repaired immediately by an authorised
ROLLER contract service workshop.
The ROLLER’S Uni-Press and ROLLER’S Multi-Press ends the pressing
opera tion automatically, emitting an acoustic signal (clicking).

NOTICE
A perfect pressing is only produced with full closure of the pressing tongs,
pressing tongs Mini, pressing ring or pressing segment. After completing
the pressing, check that the pressing jaws (10) close fully at “A” for the
pressing tongs, Mini pressing tongs (Fig. 1), the (PR-3B) pressing ring
(Fig. 18) and the 45° (PR-2B) pressing ring (Fig. 19). After completing the
pressing, check that the pressing jaws (10) close fully at “A” and on the
opposite side “B” for the (4G) pressing tongs (Fig. 15) and the (S) pressing
tongs (Fig. 16). 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. 17) and the XL (PR-3S) pressing ring. If a visible
I I
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. 11) 11 11
Note the different working range of the axial presses. The respectively latest
ROLLER sales literature applies, see also www.albert-roller.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.
3.2.1. ROLLER’S Axial-Press 25 22 V ACC, ROLLER’S Axial-Press 25 L 22 V ACC
(Fig. 11)
Insert the pre-assembled pressing sleeve fi tting into the pressing heads (14).
On the ROLLER’S Axial-Press 25 L 22 V 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
fi tting of the system’s manufacturer.
CAUTION CAUTION
Danger of cru shing! Keep your hands away from the moving pressing
heads (14)!
