occurs during pressing and the pressing process is not fi nished, 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.
3.5. Graduated charging level indicator (26) of the Li-Ion 21.6 V battery
The graduated charging level indicator shows the charging level of the battery
with 4 LEDs. At least one LED lights for a few seconds after pressing the key
with the battery symbol. The more LEDs that light green, the higher the charging
level of the battery. If a LED fl ashes red, the battery must be recharged.
3.6. Pressure monitoring, ROLLER’S Multi-Press 22 V ACC (Fig. 8) 88
The pressure is monitored during pressing in the ROLLER’S Multi-Press 22
V ACC. Upon completion of the pressing process, the pressure indicator LED
(28) lights white if the pressure is within the specifi cation. If this lights red, the
pressure was less than specifi ed. If it lights red and the drive unit is switched
off, the pressure was greater than specifi ed. Hold the reset button (13) until
the pressing rollers have moved back completely. If the pressure was out of
specifi cation, a new pressing process can be started and the pressure indicator
LED then lights white again during the pressing process. After a dwell time of
approx. 2 minutes, the LED goes out but lights up again when the drive unit is
switched back on. If the pressure indicator LED lights red, it is recommended
to have the drive unit checked/repaired by an authorised ROLLER’S customer
service workshop.
NOTICE
If the pressure is within the specifi cation and the pressure indicator LED (28)
lights white, it cannot always be assumed that the pressing tongs, the pressing
ring and the pressing segments were closed at the end of the pressing process.
Always check full closure in every pressing process, see 3.1.
3.7. Power supply unit (accessory art. no. 571535, 571565, 571567, 571578)
The power supply units are intended for mains operation of the cordless tools
in place of the battery. See the guidelines for use (Fig. 20) for the intended
use. The power supply units are equipped with overvoltage and temperature
protection. The operating state is indicated by a LED. A lit LED indicates that the
device is ready for operation. If the LED goes out or fl ashes, this indicates an
overcurrent or impermissible temperature. The drive unit cannot be used during
this time. After a dwell time, the LED lights again and work can be continued.
NOTICE
The power supply units are not suitable for outdoor use.
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to have
the ROLLER’S drive units together with all tools (e.g. pressing tongs, Mini
pressing tongs, pressing rings with adapter tongs, Mini adapter tongs, pressing
heads, expanding heads) and accessories (e.g. batteries, rapid chargers, power
supply units) sent to an authorised ROLLER contract service workshop at least
once a year for inspection and periodic checking of electrical devices. In
Germany, such periodic testing of electrical devices should be performed in
accordance with DIN VDE 0701-0702 and also prescribed for mobile electrical
equipment according to the accident prevention rules DGUV, regulation 3
"Electrical Systems and Equipment". In addition, the respective national safety
provisions, rules and regulations valid for the application site must be considered
and observed.
WARNING WARNING
Notwithstanding the servicing listed below it is recommended to send in the
ROLLER’S drive units together with all the tools (e.g. pressing tongs, pressing
tongs Mini, pressing rings with adapter tongs, adapter tongs Mini, compression
heads, expanding heads) and accessories (e.g. batteries, rapid chargers) at
least once a year to an authorised ROLLER’S customer service station for
inspection and repeated inspection of electrical equipment in accordance with
EN 62638:2010-08 (VDE 0702).
4.1. Inspection/repair
WARNING WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The gearbox of the drive unit in the ROLLER’S Uni-Press SE is maintenance -
-free. They operate in a permanent grease fi lling and therefore require no
lubrication. The motor of the ROLLER’S Uni-Press SE, ROLLER’S Uni-Press,
ROLLER’S Uni-Press ACC, ROLLER’S Uni-Press XL 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 carbon brushes. The ROLLER’S
Uni-Press SE 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
ROLLER’S safety slip clutch. All other ROLLER’S drive units (except ROLLER’S
Uni-Press SE) operate electro-hydraulically. If the pressing power is insuffi cient
or oil is lost, the drive unit must be inspected and if necessary repaired by an
authorised ROLLER’S after-sales service facility.
NOTICE
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs, pressing heads or expanding heads cannot be repaired.
4.2. Servicing
WARNING WARNING
Before service work, pull the mains plug or remove the battery!
Keep the pressing tongs, pressing tongs Mini, tongs tongs pressing rings, adapter tongs,
adapter tongs Mini pressing heads and expandin , and particularly their recep-
tacles, clean. Clean heavily soiled metal parts with the machine cleaner (Art.
No. 140119) cleaner, for example, and then protect against rust.
Clean plastic parts (e.g. housing, batteries) only with the machine cleaner (Art.
No. 140119) or 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.
Make sure that liquids never get inside the power tool. Never immerse the
power tool in liquid.
4.2.1. Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini
Pressing tongs, pressing tongs Mini, pressing rings, adapter tongs, adapter
tongs Mini must be checked regularly for smooth action. Clean pressing tongs,
pressing tongs Mini, pressing rings and adapter tongs, adapter tongs Mini if
necessary and lightly grease the bolts (12) of the pressing jaws, pressing
segments and adapter jaws, adapter tongs Mini (Fig. 1, 15 – 15 15 19) with machine 19 19
oil. Remove deposits from the pressing contour (11, 22). Check the proper
functioning of all pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs, adapter tongs Mini regularly with a test pressing with inserted pressing
fi tting. A perfect pressing is only produced with full closure of the pressing
tongs, pressing tongs Mini, pressing ring or pressing segment. After completing
the pressing, check that the pressing jaws (10) close fully at “A” for the pressing
tongs, Mini pressing tongs (Fig. 1), the (PR-3B) pressing ring (Fig. 18) and the
45° (PR-2B) pressing ring (Fig. 19). After completing the pressing, check that
the pressing jaws (10) close fully at “A” and on the opposite side “B” for the
(4G) pressing tongs (Fig. 15) and the (S) pressing tongs (Fig. 16). After comple-
ting the pressing, check that the pressing segments (21) close fully at “A” and
on the opposite side “B” for the (PR-3S) pressing ring (Fig. 17) and the XL
(PR-3S) pressing ring. If a visible burr is created on the pressing sleeve when ff
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, adapter tongs Mini 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, adapter tongs Mini to an authorised ROLLER service shop ROLLER ROLLER
for inspection.
4.2.2. 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 fi tting that requires the greatest pressing force. If the
pressing tongs, Mini pressing tongs, pressing ring or pressing segments close
completely in this pressing (see above), the drive unit is functioning reliably.
4.2.3. Axial presses
Keep the compression heads (14) and mounting bores in the pressing device
and the pressing device itself clean.
4.2.4. Pipe expanders
Keep the expanding device (15), expanding heads (16) and expanding mandrel
(18) clean. Grease the expanding mandrel (18) lightly from time to time.
