2. Preparations for Use

For use of the ROLLER'S pressing tongs, ROLLER'S pressing heads and
ROLLER'S expanding heads for the various pipe connection systems, the
currently valid ROLLER sales documents are applicable. If the system
manufacturer alters components of pipe connection systems or markets
new ones, their current application status must be enquired about at
ROLLER (Fax +49 7151 17 27 - 87).

2.1. Electrical connection

Note the mains voltage! Before connecting the drive unit or the rapid
charger, check whether voltage on the rating plate matches the mains vol-
tage. At work sites, in damp surroundings, in the open or in the case of
comparable types of use, only operate the equipment off the mains using
a 30mA fault current protected switch (FI breaker).
The battery supplied with ROLLER'S drive units and the spare batteries
are not charged. Charge the battery before initial operation. Only use the
ROLLER'S rapid charger (Art. No. 565220) for charging. Once the bat-
tery is inserted into the rapid charger, the red indicator light flashes. After
about 1 hour, the indicator light switches to permanent, meaning the
battery is charged. The battery only reaches its full capacity after several
charges.
2.2. Installing (changing) the pressing tongs (1) in radial presses (Fig. 1)
Pull the mains plug or remove the battery. Only use pressing tongs with
a system-specific pressing contour matching the press fitting system for
pressing. ROLLER'S pressing tongs have a letter on both pressing jaws
to identify the pressing contour and a number to identify the size. Consult
and comply with the instructions for installation and fitting of the system's
manufacturers. Never use non-matching pressing tongs (pressing con-
tour, size) for pressing work. The press joint could be unserviceable, and
both the machine and the pressing tongs might be damaged.
The drive unit is best placed on a bench or the floor. Installing (changing)
the pressing tongs is only possible when the press rollers (5) in are fully
retracted. If necessary, in the case of the ROLLER'S Uni-Press 2000 and
ROLLER'S Uni-Press E, set the rotation direction lever (7) to the left and
operate the inching switch (8), and in the case of the ROLLER'S Multi-
Press press the reset button (13) until the press rollers (5) are fully retracted.
Open the tongs shank (2). To do so, press the locking pin (4), the tongs
shank (2) jumps out under spring loading. Insert selected pressing tongs
(1). Push home the tongs shank (2) until the locking pin (4) engages. While
doing so, press down the pressure plate (3) directly above the tongs shank.
Do not start radial presses without pressing tongs inserted. Do not start
the pressing operation except to make a press joint. Unless counter pres-
sure is applied by the press fitting, the drive unit or pressing tongs will be
needlessly stressed.
Never operate press when the tongs shank (2) is not locked. Risk of
fracture!
2.3. Installing (changing) the pressing heads (14) in axial presses
(Figs. 6, 7, 8)
Remove the battery. Only use system-specific pressing heads. ROLLER'S
pressing heads have a letter to identify the compression sleeve system
and a number to identify the size. Consult and comply with the instruc-
tions for installation and fitting of the system's manufacturer. Never use
non-matching pressing heads (compression sleeve system, size) for pres-
sing work. The press joint could be unserviceable, and both the machine
and the pressing heads might be damaged.
Push the selected pressing heads (14) right in, if necessary turning them
until they engage (ball catch). Keep the pressing heads and locating hole
inside the pressing device clean.
2.4. Installing (changing) the expanding head (16) in ROLLER'S
Axial-Press 15 (Fig. 7)
Remove the battery. Fit the expander (15) (accessory) To do so, clean the
connecting surfaces, attach the expander, and tighten the two fillister-head
screws. Lightly grease the expanding mandrel (18). Screw the selected
expanding head as far as it will go onto the expander. Only use system-
specific expanding heads. ROLLER'S expanding heads have a letter to
identify the compression sleeve system and a number to identify the size.
Consult and comply with the instructions for installation and fitting of the
system's manufacturer. Never use non-matching expanding heads (com-
pression sleeve system, size) for expansion work. The press joint could
be unserviceable, and both the machine and the expanding heads might
be damaged.
Ensure that the compression sleeve has sufficient clearance from the
expanding head during the expansion process, otherwise the expanding
jaws (17) might become bent or broken.
For pressing jobs in cramped places, the expander attachment can be
removed.
2.5. Installing (changing) the expanding head (16) in ROLLER'S Akku-
Exparo Mini Q & E, ROLLER'S Akku-Exparo Q & E (Fig. 9)
Remove the battery. Only use genuine expanding heads for Wirsbo Quick
& Easy. Consult and comply with the instructions for installation and fitting
of the system's manufacturer. Never use non-matching expanding heads
(system, size) for expansion work. The joint could be unserviceable, and
both the machine and the expanding heads might be damaged. Lightly
grease the expanding mandrel (18). Screw the selected expanding head
as far as it will go onto the expander. ROLLER'S expanding heads P and
Cu are not suitable for the Akku pipe expander ROLLER'S Akku-Exparo
Mini Q & E, ROLLER'S Akku-Exparo Q & E, and must therefore not be
used.
3. Operation
3.1. Radial presses (Figs. 1 to 5)
Before use, always perform a trial pressing with the drive unit and the
pressing tong inserted, with the press fitting in place. The pressing tongs
must close completely. Complete closing of the pressing jaws (10) both
at their tips (Fig. 1, at "A") and at the level of the connecting link (Fig. 1,
at "B") must be observed after completion of pressing. The tightness of
the connection must be checked (country-specific regulations, standards,
guidelines etc. must be followed).
Before use, always check the pressing tongs, in particular the pressing
contour (11) of both pressing jaws (10), for damage or wear. Do not use
damaged or worn pressing tongs again. Otherwise there is a risk of in-
correct pressing or accidents.
If during closing of the pressing tongs a marked ridge is created on the
compression sleeve, the pressing may be defective or not tight (see 5.
Trouble).
3.1.1. Working procedure
Press the pressing tongs (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).
In the case of the ROLLER'S Uni-Press E, set the rotation direction lever
(7) to the right (advance) and press the inching switch (8). Hold down the
inching switch (8) until pressing is completed and the pressing tongs are
closed. Set the rotation direction lever (7) to the left (return) and press the
switch (8) until the press rollers have retracted and the slipping clutch
responds. Do not put unnecessary loads on the slipping clutch.
In the case of the ROLLER'S Uni-Press 2000, set the rotation direction
lever (7) to the right (advance) and press the inching switch (8). Hold down
the inching switch (8) until the drive unit switches off automatically. Set the
rotation direction lever (7) to the left (return) and press the inching switch
(8) until the drive unit switches off or the slipping clutch responds. Do not
put unnecessary loads on the slipping clutch.
In the case of the ROLLER'S Multi-Press, hold down the inching switch
(8) until the pressing tongs are completely closed. This is indicated by an
acoustic signal (clicking). Press the reset button (13) until the press rol-
lers (5) are fully retracted.
In the case of the ROLLER'S Multi-Press Mini ACC, ROLLER'S Multi-
Press ACC and the ROLLER'S Uni-Press ACC, hold down the inching
switch (8) until the pressing tongs are completely closed. After completion
of pressing, the drive unit switches automatically to return (forced return).
Press the pressing tongs together manually so that they can be removed
from the press fitting.
3.1.2. Operating safety
The ROLLER'S Uni-Press 2000 is fitted with a torque-controlled electro-
nic cutout circuit. This switches off the drive unit once the pressing ope-
ration has ended, i.e. when the pressing tongs are closed. 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 tor-
que-controlled safety slipping clutch is operative in both end positions of
the press rollers.
