pilot light stops flashing and lights steadily after approx. 1 hour meaning that
the battery is charged. The battery only reaches its full capacity after several
charging cycles.
2.2. Selecting the bending tools
ROLLER'S Arco, ROLLER'S Akku-Arco
Put a bending former (1) (Fig. 1) corresponding to the pipe size onto the
square (2). The mounting is designed such that the bending former can only
be fully fitted in one direction. Place in readiness the back former (3) suitable
for the pipe size and the insert bolt (4).
ROLLER'S Arco 50, Ø 35–50
Put a bending former (1) (Fig. 1) corresponding to the pipe size onto the
square (12). The mounting is designed such that the bending former can
only be fully fitted in one direction. Place in readiness the back former (3)
suitable for the pipe size and the insert bolt (4). Insert the appropriate sized
back former (3), the support (11) and the insert bolt (4).
ROLLER'S Arco 50, Ø 10–40
Remove adaptor block (12) and replace with adaptor block (14) into the drive
unit. Put a bending former (1) (Fig. 1) corresponding to the pipe size onto
the square (14). The mounting is designed such that the bending former can
only be fully fitted in one direction. Insert the appropriate sized back former
(3), the support (13) and the insert bolt (4).
When using the ROLLER'S Arco 50, the support (11) and (13) respec-
tively should be attached above the bending and back formers, for all
sizes. Up to and including sizes 24 R75 (¾" R75), the support (15) should
also be attached below. This is mounted on one side on the adaptor
block collar (14), and on the other side with the locating pin (16) in the
outermost bore hole of the support (15) marked out in the housing (see
3.1.).
The drive unit gets damaged when bending without this support!
3. Operation
3.1. Working procedure
Turn changeover switch (7) to »L« (reverse). Press inching switch (8) while
gripping the motor handle (9) at the same time. The bending former turns
clockwise into its starting position in which the slipping clutch is effective. Re-
lease the inching switch immediately. Do not put unnecessary load on the
clutch. Turn changeover switch (7) to »R« (forward). Place pipe into bending
former so that the pipe end projects at least 10 mm beyond the driver (10).
With the pipe sizes 22 to 50 mm, the pipe must be pressed into the radius
of the bending former. Lower the insert bolt (4) through the matching back
former (3) and into the corresponding hole bored in the machine.
When using the ROLLER'S Arco 50, the support (11) and (13) respec-
tively should be attached above the bending and back formers, for all
sizes. Up to and including sizes 24 R75 (¾" R75), the support (15) should
also be attached below. This is mounted on one side on the adaptor
block collar (14), and on the other side with the locating pin (16) in the
outermost bore hole of the support (15) marked out in the housing (see
3.1.).
The drive unit gets damaged when bending without this support!
Ensure here that the insert bolt (4) for the sizes up to 22 mm (
the left-hand locating hole (5) and for larger sizes into the right-hand hole (6).
Operate the inching switch (8) to bend the pipe. Towards the end of the re-
quired bend, only press the switch lightly, so that the final point is approa-
ched slowly and thereby precisely. A scale is provided on each bending for-
mer, together with the mark on the back former, ensures precise manufac-
ture of arcs of up to 180° / Arco 50 up to 90°. Be aware that various materials
spring back differently. If a 180° bend / Arco 50: 90° bend is produced and
reaches the end position, the slipping clutch comes into action again. Re-
lease the inching switch immediately. Turn changeover switch (7) to »L«
(reverse). Allow the bending former to run back a few degrees until the pipe
is unclamped by light pressure on the inching switch (8). Pull out the insert
bolt (4) and remove the bent pipe. When bending on site, the bending for-
mer too can be taken off for easier removal of the bent pipe.
Only allow the bending former to return to its starting position after removal
of the pipe, as otherwise the produced bend might be damaged. While ben-
ding stainless steel pipes of pressfitting systems one must pay attention that
the mark at the pipe caused by the driver (10) does not lie in the sealing area
of the pressing joint.

3.2. Bending to size
If a bend is required at a certain point on the pipe, a lenght correction must
be made to suit the pipe size.
For a 90° bend, the correction dimension X given in Fig. 2 must be taken in-
to account. The set dimension L must be reduced by the amount X here. If
the dimension L should be 400 mm for the pipe size 22, the dimension line
must be made on the pipe at 320 mm. This line is then – as shown in Fig. 2
– to be aligned with the 0-mark on the bending former.
3.3. Unit support ROLLER'S Arco, ROLLER'S Akku-Arco
Vertically adjustable unit supports on tripod (Art.No. 586100) and for moun-
ting on the work bench (Art.No. 586150) available as accessories.
4. Maintenance
Pull out the mains plug and remove the battery before maintenance and
repair work! This work must be carried out solely by specialists or persons
familiar with the unit.
4.1. Maintenance
ROLLER'S Arco, ROLLER'S Arco 50 and ROLLER'S Akku-Arco are main-
tenance-free. The gearbox has a permanent grease filling and therefore re-
quires no lubrication.
4.2. Inspection/Servicing
The motor of the ROLLER'S Arco and ROLLER'S Arco 50 has carbon brus-
hes. These are subject to wear and must therefore be checked periodically
and replaced if necessary. To do so, unscrew the 4 screws on the motor
handle about 3 mm, pull the motor handle back and remove the two covers
from the motor housing. See also "5. Action in Case of Trouble".
5. Connection
In the ROLLER'S Akku-Arco make absolutely sure that the plus pole on the
motor (plastic base of the connecting tab with lug) is connected to switch ter-
minal 1 with the red wire.

running.
Cause: • Pipe being bent has walls too thick.
