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 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).
Important: A perfect pressing is only made with the full closing of the
pressing tong or adapter tong and pressing ring. Full closure of the
pressing jaws (10) or pressing segments (21) both at their tips (Fig. 1 and
Fig. 14, at "A") and at the height of the connecting lug (Fig. 1 and Fig. 14
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)
3.2.1. Pressing with the ROLLER'S Axial-Press 15 and Ax-Press 40
Place the preassembled compression sleeve fitting inside the pressing heads
(14) and press them into the latter. Only press the inching switch (8) lightly, so
that the pressing heads move together slowly until they are in contact with the
compression sleeve fitting.
Caution – danger of cru shing! Keep your hands away from the moving
pressing heads! 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.
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.
3.2.2. Expansion with ROLLER'S Axial-Press 15
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.
4. Maintenance
Important! Irrespective of the above maintenance work, the ROLLER drive
All manuals and user guides at all-guides.com
units must be returned together with all tools (for ex. pressing tongs, pressing
heads, expanding heads) at least once a year to an authorised ROLLER
after-sales service facility for inspection.
4.1. Maintenance
Before maintenance work, pull the mains plug or remove the battery.
Keep the pressing tongs, 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, adapter tongs and pressing rings
Pressing tongs, pressing rings and adapter tongs must be checked regularly
for smooth action. Clean pressing tongs, 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 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 rings and adapter tongs may no longer be
used. In case of doubt, send in the drive machine together with all pressing
tongs, 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 close completely during
this pressing operation (see above), the drive unit is functionally reliable.
The ROLLER'S Multi-Press Mini ACC and ROLLER'S Multi-Press ACC is fitted
with an electronic servicing feature. After about 10,000 pressing operations,
the diode on the pistol grip (9) starts to flash. An inspection is then due. This
is performed by an autho rised ROLLER after-sales service facility.
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. ROLLER'S Akku-Exparo Q & E
Keep the expanding heads (16) and expanding mandrel (18) clean. Lightly
grease the expanding mandrel (18) from time to time.
4.2. Inspection/repair
Before any repair work, pull the mains plug or remove the battery. This work
may only be performed by authorised experts or by trained personnel.
After around 10,000 pressing/expanding operations, but at least once a year,
inspection of the pressing/expanding tool to an authorised ROLLER after -sales
service facility is necessary.
The gearbox of the drive unit in the ROLLER'S Uni-Press E is maintenance -
free. They operate in a permanent grease filling and therefore require no
lubrication. The motor of the ROLLER'S Uni-Press E, ROLLER'S Uni-Press
and ROLLER'S Uni-Press ACC has carbon brushes. These are subject to wear
and must therefore be inspected or replaced from time to time. Only use genuine
ROLLER'S Uni-Press carbon brushes. The ROLLER Akku drive units operate
electrohydraulically. If the pressing power is insufficient or oil is lost, the drive
unit must be inspected and if necessary repaired by ROLLER or by an author-
ised ROLLER after-sales service facility.
Damaged or worn pressing tongs, pressing heads or expanding heads cannot
be repaired.
