manufacturer/supplier of the used system. Never expand with the wrong
expanding heads (compression sleeve system, size). The connection could be
useless and the machine and expanding heads could be damaged.
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
3.1. Radial presses (Figs. 1 to 4 and 14 to 17)
The pressing tongs, Mini pressing tongs, pressing ring and adapter tongs,
especially the pressing contour (11, 22) of the pressing jaws (10) or all 3 pressing
segments must be checked for damage and wear before every use. Damaged
or worn pressing tongs, Mini pressing tongs, pressing rings and adapter tongs
may no longer be used. There is otherwise a risk of incorrect pressing or
accidents.
A trial pressing with inserted press fitting 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 before every use. The pressing tongs,
Mini pressing tongs (1), the pressing ring (20) with adapter tongs must fit 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. 14 to 17 at "A") and
on the opposite side (Fig. 1 and Fig. 14 to 17 at "B"). Check the tightness of
the connection (observe national specifications, 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
For preventing damages make sure to avoid operating situations like
exemplarily shown in Fig. 13 through 15, that no distortion between
pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, fitting
and drive unit occurs. There is a risk of fracture and flying 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 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 adaptor tongs so that the radii of the adaptor tongs
lie firmly on the cylinder rollers of the pressing ring and the pressing ring on
the pressfitting.
On ROLLERʼS Uni-Press E / ROLLERʼS Uni-Press SE push the rotation direction
lever (7) to the right (feed) and press the safety inching switch (8). Keep the
safety inching switch (8) pressed until the pressing is finished and the pressing
tongs or pressing ring are closed. Push the rotation 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 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 ROLLERʼS Uni-Press and ROLLERʼS Multi-Press, keep the
safety 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 ROLLERʼS Multi-Press Mini ACC, ROLLERʼS Multi-Press
ACC and ROLLERʼS Uni-Press ACC, keep the safety 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). 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 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
On ROLLERʼS Uni-Press E / ROLLERʼS Uni-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 slip clutch.
ROLLERʼS Uni-Press SE is equipped with an electronic safety circuit which
protects the drive unit against overloading.
The ROLLERʼS Uni-Press and ROLLERʼS Multi-Press ends the pressing
opera tion automatically, emitting an acoustic signal (clicking).
The ROLLERʼS Multi-Press Mini ACC, ROLLERʼS Multi-Press ACC and
ROLLERʼS 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. 14 to 17 at "A") and on the opposite side (Fig.
1 and Fig. 14 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. 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. 5, 8)
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
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. ROLLERʼS Axial-Press 40 (Fig. 5)
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.
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 shing! Keep your hands away from the moving pressing
heads (14)!
3.2.2. ROLLERʼS Axial-Press 25 ACC, ROLLERʼS Axial-Press 25 L ACC (Fig. 8)
Insert the pre-assembled pressing sleeve fitting into the pressing heads (14).
On the ROLLERʼS Axial-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 shing! Keep your hands away from the moving pressing
heads (14)!
3.3. Pipe expanders
3.3.1. ROLLERʼS Akku-Exparo Q & E ACC (Fig. 6)
Read and observe the installation and assembly instructions of the manufacturer/
supplier of the used system. Slide a Q & E ring of appropriate size onto the
pipe. Insert the expansion head into the pipe and press the expanding head/
drive unit against the pipe. Switch on the drive unit (8). When the expanding
head is opened, the drive unit switches automatically to return and the expanding
head is closed again. Keep holding the safety inching switch (8) down in the
ROLLERʼS Akku-Exparo Q & E ACC and push the expanding head/drive unit
further. Turn the pipe slightly. Keep repeating the expansion process until the
expanding jaws (17) are slid all the way into the pipe.
3.3.2. ROLLERʼS Akku-Exparo P (Fig. 9)
Push the compression sleeve over the pipe in the ROLLERʼS Akku-Exparo P,
insert the expanding head into the pipe up to the stop and press the expanding
head/drive unit against the pipe. Switch on the drive unit (8). Make sure that
the compression sleeve is far enough away from the expanding head in the
expanding process because otherwise the expanding jaws (17) can bend or
break. Keep the safety inching switch (8) pressed until the pipe is expanded.
