adapter tong (pressing contour, size). The press joint could be rendered useless
and the machine and pressing tong, pressing tong Mini, pressing ring and
adapter tong could be damaged.
It is best to place the drive machine on a bench or on the floor. The pressing
tong, pressing tong Mini or adapter tong can only be installed (changed) when
the press rollers (5) are fully retracted. If necessary, in the case of the ROLLER’S
Uni-Press E, set the rotation direction lever (7) to the left and operate the inching
switch (8), and in the case of the ROLLER’S Uni-Press and ROLLER’S Multi-
Press press the reset button (13) until the press rollers (5) are fully retracted.
Open the tongs shank (2). To do so, press the locking pin (4), the tongs shank
(2) jumps out under spring loading. Insert the selected pressing tong, pressing
tong Mini (1) or adapter tong (19). Push forward the tong retaining bolt (2) until
the locking pin (4) snaps into place. Press down the pressure plate (3) directly
over the tong retaining bolt. Do not start radial presses without pressing tong,
pressing tong Mini or pressing ring with adapter tong inserted. Only start the
pressing process to make a press joint. Without pressing counterpressure by
the press fitting the drive machine or pressing tong, pressing tong Mini, pressing
ring and adapter ring will be exposed to unnecessarily high stress.
CAUTION
Never operate press when the tongs shank (2) is not locked. Risk of
fracture!
2.3. Installing (changing) the pressing heads (14) in axial presses
(Figs. 7, 10)
Remove the battery. Only use system-specific pressing heads. ROLLER’S
press ing heads have a letter to identify the compression sleeve system and a
number to identify the size. Consult and comply with the instructions for instal-
lation and fitting of the system’s manufacturer. Never use non-matching pressing
heads (compression sleeve system, size) for pressing work. The press joint
could be unserviceable, and both the machine and the press ing heads might
be damaged.
Push the selected pressing heads (14) right in, if necessary turning them until
they engage (ball catch). Keep the pressing heads and locating hole inside the
pressing device clean.
2.4. Installing (changing) the expanding head (16) in ROLLER’S Akku-Exparo
Q & E ACC (Fig. 8, 9)
Pull out the mains plug or remove the battery. Only use genuine expanding
heads for Uponor Quick & Easy. Consult and comply with the instructions for
installation and fitting of the system’s manufacturer. Never use non-matching
expanding heads (system, size) for expansion work. The joint could be unser-
viceable, and both the machine and the expanding heads might be damaged.
Grease the cone of the expanding mandrel (18) lightly. Screw the selected
expanding head as far as it will go onto the expander. Read and follow the
installation and assembly instructions of the system manufacturer. ROLLER’S
expanding heads P and Cu are unsuitable for the ROLLER’S Akku-Exparo
Q & E ACC pipe expander and may therefore not be used.
2.5. Mounting (changing) the expanding head (16) on the ROLLER’S Akku-
Exparo Cu ACC (Fig. 12)
Remove the battery. Grease the cone of the expanding mandrel lightly. Screw
the selected expanding head onto the expanding device 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 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 expanding
device complete with screwed on expanding head must be screwed onto the
drive machine until the segments of the expanding head are fully open. The
expanding head must be secured with the locking nut in this position.
2.6. Mounting (changing) the expanding head (16) on the ROLLER’S Akku-
Exparo P ACC (Fig. 11)
Remove the battery. Grease the cone of the expanding mandrel (18) lightly.
Screw the selected expanding head onto the expanding device to the stop.
Only use system-specific expanding heads. Expanding heads are labelled with
letters to identify the compression sleeve system and with a number to identify
the size. Read and follow the installation and assembly instructions of the
system manufacturer. Never expand with the wrong expanding heads (compres-
sion sleeve system, size). The connection could be useless and the machine
and expanding heads could be damaged.
3. Operation
3.1. Radial presses (Figs. 1 to 5 and 16 to 19)
A test pressing with inserted press fitting must be made with the drive machine
and the respectively inserted pressing tong, pressing tong Mini, pressing ring
with adapter tong before every use. The pressing tong (1), pressing ring (20)
or pressing segments (21) must close fully. Full closure of the pressing jaws
(10), pressing rings (20) or pressing formers (21) both at their tips (Fig. 1, and
Fig. 16 to 19 at "A") and on the opposite side (Fig. 1 and Fig. 16 to 19 at "B")
can be observed after completing the pressing. Check the tightness of the
connection (observe national specifications, standards, regulations, etc.)
The pressing tong, pressing tong Mini, pressing ring and adapter tong, and
especially the pressing contour (11 / 22) of both pressing jaws (10) or all 3
pressing segments must be checked for damage and wear before every use.
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings or adapter
tongs may no longer be used. There is otherwise a risk of incorrect pressing
or accidents.
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).
For preventing damages make sure to avoid operating situations like exempla-
rily shown in Fig. 13 through 15, that no distortion between pressing tongs,
pressing tongs Mini, pressing rings, adapter tongs, fitting and drive unit occurs.
3.1.1. Working procedure
Press the pressing tongs, pressing tongs Mini (1) together manually until they
can be pushed over the press fitting. Always position the drive unit with the
pressing tongs on the press fitting at right angles to the pipe axis. Release the
pressing tongs so that they close around the press fitting. Hold the drive unit
by the housing grip (6) and the pistol grip (9).
Place the pressing ring (20) around the pressing fitting. Insert the pressing tong
(19) into the drive unit and lock the tong retaining bolt. Press the pressing tong
(19) together with your hand so that the adapter tong can be placed on the
pressing ring. Release the adapter tong so that the adapter tong is tightly applied
to the pressing ring and the pressing ring to the pressfitting.
In the case of the ROLLER’S Uni-Press E, set the rotation direction lever (7)
to the right (advance) and press the inching switch (8). Keep the inching switch
(8) pressed until the pressing is finished and the pressing tong or pressing ring
is closed. Set the rotation direction lever (7) to the left (return) and press the
switch (8) until the press rollers have retracted and the slipping clutch responds.
Do not put unnecessary loads on the slipping clutch.
In the case of the ROLLER’S Uni-Press and ROLLER’S Multi-Press, keep the
inching switch (8) pressed until the pressing is finished and the pressing tong
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 ROLLER’S Multi-Press Mini ACC, ROLLER’S Multi-Press
ACC and ROLLER’S Uni-Press ACC, keep the inching switch (8) pressed until
the pressing is finished and the pressing tong or pressing ring is completely
closed. After completion of press ing, the drive unit switches automati cally to
return (forced return).
Press the pressing tongs together with your hand so that they can be removed
from the pressfitting together with the drive unit. Press the adapter tong 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
In the case of the ROLLER’S Uni-Press E, the pressing operation is ended by
releasing the inching switch (8). For the mechanical safety of the drive units,
a torque-controlled safety slipping clutch is operative in both end positions of
the press rollers.
The ROLLER’S Uni-Press and ROLLER’S Multi-Press ends the pressing
opera tion automatically, emitting an acoustic signal (clicking). The ROLLER’S
Multi-Press Mini ACC, ROLLER’S Multi-Press ACC and ROLLER’S Uni-Press
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. 16 to 19 at "A") and on the opposite side (Fig.
1 and Fig. 16 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. This permits immediate switching off of the drive units at any time,
particularly if a potential hazard arises. The drive units can be switched to the
return function in any position.
3.2. Axial presses (Figs. 7, 10)
3.2.1. Pressing with the ROLLER’S Axial-Press 40 (Fig. 7)
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 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.
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 follow the installa-
tion and assembly instructions of the system manufacturer.
Pressing with ROLLER’S Axial-Press 25 ACC, ROLLER’S Axial-Press 25 L
ACC (Fig. 10)
