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 manually so that they can be removed from
the press fitting. Press the pressing tong together with your hand so that it can
be removed from the pressfitting. Press the adapter tong together with your
hand so that it can be removed from the pressing ring with the device. 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, mini pressing tongs or pressing ring. 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.
If a visible burr is created on the pressing sleeve when closing the pressing
tong 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. 6, 7, 10)
3.2.1. Pressing with the ROLLER'S Axial-Press 15 and Axial-Press 40 (Fig. 6, 7)
Place the preassembled compression sleeve fitting inside the pressing heads
(14) and press them into the latter. Hold the drive unit by the housing grip (6)
and the pistol grip (9), and keep the inching switch (8) pressed until the compres-
sion 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.
Pressing with ROLLER'S Axial-Press 25 ACC, ROLLER'S Axial-Press 25 L
ACC (Fig. 10)
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 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).
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.
In the case of the compression sleeve system RV, preliminary and final pressing
is necessary, i.e. the pressing heads must first be inserted with a wide spacing
of the receptacles for the compression sleeve fitting. Before a second pressing
operation, the pressing heads are set to a narrow spacing of the receptacles
for the compression sleeve fitting by a 180° rotation. Consult and comply with
the instructions for installation and fitting of the system's manufacturer.
The ROLLER'S Axial-Press 25 L ACC must be used for the BA/SP/UNI compres-
sion sleeve systems. Note that the compression heads must be inserted into
the pressing machine in such a way that the pressing can be done in one stroke
if possible. This is not possible in some cases and pre-pressing and finish
pressing is necessary. For this one compression head or both compression
heads must be inserted turned 180° before the second pressing process so
that they are closer together. Read and follow the installation and assembly
instructions of the system manufacturer.
CAUTION Danger of cru shing! Keep your hands away from the moving
pressing heads (14)!
3.2.2. Expansion with ROLLER'S Axial-Press 15 (Fig. 6)
Push the compression sleeve over the pipe, insert the expanding head as far
as it will go into the pipe, and press the expanding head/drive unit against the
pipe. Switch on the drive unit (8). Ensure that the compres sion sleeve has
during the expansion process sufficient clearance from the expanding head,
otherwise the expanding jaws (17) might become bent or broken. Hold down
the inching switch (8) until the pipe has been expanded. This is also indicated
by an acoustic signal (clicking). Press the reset button (13) until the expanding
head has closed again. If necessary repeat the expansion. Consult and comply
with the instructions for installation and fitting of the system's manufacturer.
3.3. ROLLER'S Akku-Exparo Q & E (Fig. 8)
Consult and comply with the instructions for installation and fitting of the system's
manufacturer. 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 inching switch (8) down and push the expanding head/
drive unit further. Keep repeating the expansion process until the expanding
jaws (17) are slid all the way into the pipe. Consult and comply with the instruc-
tions for installation and fitting of the system's manufacturer.
Expanding with ROLLER'S Akku-Exparo P, ROLLER'S Akku-Exparo Cu
(Fig. 11, 12)
Push the compression sleeve over the pipe in the ROLLER'S Akku-Exparo P,
insert the expanding head into the pipe up to the stop and press the expanding
head/drive machine against the pipe. Switch on the drive machine (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 inching switch (8) pressed until the pipe is expanded. This
is indicated by an acoustic signal (click). Expand several times if necessary.
Read and follow the installation and assembly instructions of the system
manufacturer.
In the ROLLER'S Akku-Exparo Cu, insert the expanding head into the pipe and
press the expanding head/drive machine against the pipe. Switch on the drive
machine. If the expanding head is open, the drive machine switches auto-
matically to return and the expanding head is closed again. Read and follow
the installation and assembly instructions of the system manufacturer.

3.4. Charging state control of the battery
All ROLLER'S cordless presses will be equipped as of 2011-01-01 with a green/
red LED (23).
Functions:
LED lights green = battery good
LED lights red = the battery must be charged. The drive machine ends the
current pressing cycle and cannot be switched back on afterwards.

4. Maintenance

NOTICE
Notwithstanding the maintenance listed below we recommend you
to send in the ROLLER'S drive machines together with all tools (e.g. pressing
tongs, pressing tongs Mini, compression heads, expanding heads, adapter
tongs, pressing ring) at least once a year to an authorised ROLLER service
shop for inspection.
4.1. Maintenance
WARNING
Before maintenance work, pull the mains plug or remove
the battery!
Keep the pressing tongs, pressing tongs Mini, adapter tongs, pressing rings,
pressing heads and expanding heads, and particularly their receptacles, clean.
Clean heavily soiled metal parts with turpentine oil, for example, and then
rustproof them.
Clean plastic parts (for ex. housing, batteries) only with a mild soap and a damp
cloth. Do not use domestic cleaning agents. These frequently contain chemicals
that can attack plastic parts. On no account use petrol, turpentine oil, thinners
or similar products to clean plastic parts.
Ensure that liquids never get inside the electrical equipment. Never immerse
the electrical equipment in liquid.
4.1.1. Pressing tongs, pressing tongs Mini, adapter tongs and pressing rings
Pressing tongs, pressing tongs Mini, pressing rings and adapter tongs must
be checked regularly for smooth action. Clean pressing tongs, pressing tongs
Mini, pressing rings and adapter tongs if necessary and lubricate the bolts (12)
of the pressing jaws, pressing segments and adapter jaws with machine oil.
Remove deposits from the pressing contour (11). Check the proper functioning
of all pressing tongs, pressing tongs Mini, pressing rings and adapter tongs
regularly with a test pressing with inserted pressing fitting. The pressing jaws
(10) must close fully both at their tips (Fig. 1, at "A") and at the height of the
connecting lug (Fig. 1 at "B") after completing the pressing. The pressing
segments (21) must closed after completing the pressing. Damaged or worn
pressing tongs, pressing tongs Mini, pressing rings and adapter tongs may no
longer be used. In case of doubt, send in the drive machine together with all
pressing tongs, pressing tongs Mini, pressing rings and adapter tongs to an
authorised ROLLER after-sales service facility for inspection.
4.1.2. Radial presses
Keep the press tongs receptacle clean, in particular clean the press rollers (5)
and tongs shank (2) at regular intervals and then lubricate them with machine
oil. Check the functional reliability of the drive unit regularly by making a pressing
with the largest press fitting used. If the pressing tongs, pressing tongs Mini
close completely during this pressing operation (see above), the drive unit is
functionally reliable.
4.1.3. Axial presses
Keep the pressing heads (14) and locating holes inside the pressing device
clean. Keep the expanding heads (16) and expanding mandrel (18) clean.
Lightly grease the expanding mandrel (18) from time to time.
4.1.4. Pipe expanders
