2.4. Assembly (changing) of the expander (15), the expanding head (16) on
ROLLER'S Akku-Exparo 22 V ACC (Fig. 8)
Choose an expander (15) to match the expanding head (16). Use the expander
Cu for the ROLLER'S Cu expanding heads. Use the expander P for the
ROLLER'S P expanding heads. Only use system-specifi c expanding heads.
ROLLER'S P expanding heads are labelled with letters to identify the compres-
sion sleeve system and a number to identify the size, ROLLER'S Cu expanding
heads only with a number to identify the size. The expanding heads of the
Uponor systems Quick & Easy and Giacomini GX fi t the Q & E expander. Read
and observe the installation and assembly instructions of the manufacturer/
supplier of the used system. Never expand with an unsuitable expander, unsuit-
able expanding heads (system, size). The joint could be useless and the machine
and expanding heads could be damaged. Grease the cone of the expanding
mandrel lightly. Screw the selected expanding head onto the expanding device
(18) to the stop. The expanding device must now be set so that the thrust of
the drive machine is taken up by the drive machine and not the expanding
head at the end of the expanding. Unscrew the expanding device (15) complete
with screwed on expanding head from the drive machine for this. Let the feed
piston run forward as far as possible without the machine switching into
reverse. In this position the expander with screwed-on expanding head must
be screwed onto the drive unit until the expanding jaws (17) of the expanding
head (16) are fully open. The expanding head must be secured with the
locking nut (24) in this position.
NOTICE
Make sure that the compression sleeve is far enough away from the expanding
head (16) in the expanding process because otherwise the expanding jaws
(17) can bend or break.
3. Operation
CAUTION CAUTION
After the drive unit has been in storage for a long period of time, the overpres-
sure valve must be actuated fi rst by pressing the reset button (13) before putting
back into operation. If it is stuck or stiff, it may not be pressed. The drive unit
must be handed over to an authorized ROLLER'S customer service workshop
for inspection.
3.1. Radial presses (Figs. 1 to 7 and 13 to 17) 1 to 7 and 13 to 17 1 to 7 and 13 to 17)
The pressing tongs, Mini pressing tongs, pressing ring, adapter tongs and Mini The pressing tongs, M 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 fi tting 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 fi t 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. 13 to 17 at "A") and on the opposite side (Fig. 1 and Fig. 13 to
17 at "B"). Check the tightness of the connection (observe national specifi ca-
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 CAUTION
For preventing damages make sure to avoid operating situations like
exemplarily shown in Fig. 10 through 12, 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
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 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 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, ROLLER'S Multi-Press Mini S 22 V ACC, ACC, ROLLER'S Multi-Press Mini S 22 V ACC, ROLLER'S Multi-Press 22 V
ACC, ROLLER'S Uni-Press ACC and ROLLER'S Uni-Press XL ACC, keep the ACC,
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 ROLLER'S Uni-Press SE the pressing process is ended by releasing the
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 jaws (10), pressing rings (20) and pressing segments
(21) at "A" and "B" (Fig. 1, and Fig. 13 to 17) closed, this is not critical. However,
if the drive unit already switches off before pressing is complete (pressing jaws,
pressing rings and pressing segments at "A" and "B" not closed), work may not
be continued and the drive unit must be checked/repaired immediately by an
authorised ROLLER contract customer service workshop.

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. 13 to 17 at "A") and on the opposite side (Fig.
1 and Fig. 13 to 17 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. 9) 9) 9
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. 9)
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.
