lising the expanded pipe, press the reset button (13) until the expanding mandrel
(18) has been pulled right back. Expand several times if necessary. Turn the
pipe slightly. Read and follow the installation and assembly instructions of the
system manufacturer.
3.3.3. ROLLERʼS Akku-Exparo P ACC, ROLLERʼS Akku-Exparo Cu ACC
(Fig. 9, 10)
Push the compression sleeve over the pipe in the ROLLERʼS Akku-Exparo P
ACC, 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 safety inching switch (8) pressed until
the pipe is expanded. This is indicated by an acoustic signal (click). Expand
several times if necessary. Turn the pipe slightly. Read and observe the instal-
lation and assembly instructions of the manufacturer/supplier of the used system.
In the ROLLERʼS Akku-Exparo Cu ACC, 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. If the expanding head is open, the drive
machine switches automatically to return and the expanding head is closed
again. Read and observe the installation and assembly instructions of the
manufacturer/supplier of the used system.
3.4. Battery charging status check with complete discharge protection
All ROLLERʼS cordless presses made as of 2011-01-01 are equipped with an
electronic battery charging status check with battery charge indication by a
2-coloured green/red LED (23). The LED lights green when the battery is fully
or still sufficiently charged. The LED lights red when the battery must be charged.
If this condition occurs during pressing and the pressing process is not finished,
the pressing must be completed with a fully charged Li-Ion battery. If the drive
unit is not used, the LED goes out after approx. 2 hours but comes on again
when the drive unit is switched back on.
4. Maintenance
WARNING
Notwithstanding the servicing listed below it is recommended to send in the
ROLLERʼS drive units together with all the tools (e.g. pressing tongs, pressing
tongs Mini, pressing rings with adapter tongs, compression heads, expanding
heads) and accessories (e.g. batteries, rapid chargers) at least once a year to
an authorised ROLLER customer service station for inspection and repeated
inspection of electrical equipment in accordance with EN 62638:2010-08 (VDE
0702).
4.1. Servicing
WARNING
Before service work, pull the mains plug or remove the battery!
Keep the pressing tongs, pressing tongs Mini, pressing rings, adapter tongs,
pressing heads and expanding heads, and particularly their receptacles, clean.
Clean heavily soiled metal parts with the urpentine oil, for example, and then
protect against rust.
Clean plastic parts (e.g. 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.
5. Trouble
For preventing damages make sure to avoid operating situations like exemplarily shown in Fig. 11 through 13, that no distortion between pressing tongs, pressing
tongs Mini, pressing rings, adapter tongs, fitting and drive unit occurs.
5.1. Fault: Drive unit does not work.
Cause:
● Worn carbon brushes (ROLLERʼS Uni-Press E / SE, ROLLERʼS Uni-Press,
ROLLERʼS Uni-Press ACC).
● Mains lead defective (ROLLERʼS Uni-Press E / SE, ROLLERʼS Uni-Press,
ROLLERʼS Uni-Press ACC).
● Battery depleted or defective (ROLLERʼS cordless drive units).
● Drive unit defective.
5.2. Fault: Radial press does not finish the pressing, pressing tongs, Mini pressing tongs, pressing ring, adapter tongs do not close fully.
Cause:
● Drive unit overheated (ROLLERʼS Uni-Press E / SE, ROLLERʼS Uni-Press,
ROLLERʼS Uni-Press ACC).
● Worn carbon brushes (ROLLERʼS Uni-Press E / SE, ROLLERʼS Uni-Press,
ROLLERʼS Uni-Press ACC).
● Slip clutch defective (ROLLERʼS Uni-Press E / SE).
● Battery depleted or defective (ROLLERʼS cordless drive units).
● Drive unit defective.
4.1.1. Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs
Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs must be
checked regularly for smooth action. Clean pressing tongs, pressing tongs Mini,
pressing rings and adapter tongs if necessary and lightly grease the bolts (12)
of the pressing jaws, pressing segments and adapter jaws (Fig. 1, 14 – 17) with
machine oil. Remove deposits from the pressing contour (11). Check the proper
functioning of all pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs regularly with a test pressing with inserted pressing fitting. 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 – 17 at "A") and on the opposite side (Fig. 1 and Fig. 14 – 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).
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings, 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, adapter
tongs to an authorised ROLLER service shop 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 lightly grease them with
machine oil. Check the functional safety of the drive unit regularly by making
a pressing with the press fitting that requires the greatest pressing force. If the
pressing tongs, pressing tongs Mini, pressing rings close completely during
this pressing operation (see above), the drive unit is functionally reliable.
4.1.3. Axial presses
Keep the compression heads (14) and mounting bores in the pressing device
and the pressing device itself clean.
4.1.4. Pipe expanders
Keep the expanding device (15), expanding heads (16) and expanding mandrel
(18) in ROLLERʼS Akku-Exparo Cu ACC, ROLLERʼS Akku-Exparo P, ROLLERʼS
Akku-Exparo P ACC, ROLLERʼS Akku-Exparo Q & E ACC clean. Grease the
expanding mandrel (18) lightly from time to time.
4.2. Inspection/repair
WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualified personnel.
The gearbox of the drive unit in the ROLLERʼS Uni-Press E / ROLLERʼS Uni-
Press SE is maintenance -free. They operate in a permanent grease filling and
therefore require no lubrication. The motor of the ROLLERʼS Uni-Press E,
ROLLERʼS Uni-Press SE, ROLLERʼS Uni-Press, ROLLERʼS 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 ROLLERʼS carbon brushes.
The ROLLERʼS Uni-Press E drive unit has a safety slip clutch. This is subject
to wear and must therefore be checked and renewed from time to time. Use
only an original ROLLERʼS safety slip clutch. All other ROLLERʼS drive units
(except ROLLERʼS Uni-Press E / ROLLERʼS Uni-Press SE) operate electro-
hydraulically. 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 authorised
ROLLER after-sales service facility.

tongs, pressing heads or expanding heads cannot be repaired.
