Only use a ROLLER'S rapid charger for charging. New Li-Ion batteries and
Li-Ion batteries which have not been used for a long time only reach full capacity
after several charges. Non-rechargeable batteries may not be charged.
Rapid charger Li-Ion/Ni-Cd (Art. No. 571560)
The left control lamp lights up and remains green when the mains plug is
plugged in. If a battery is inserted in the rapid charger, the green control lamp
flashes to indicate that the battery is charging. The green light stops flashing
and remains on to signal that the battery is fully charged. If the red control lamp
flashes, the battery is defective. If the red control lamp comes on and remains
on, this indicates that the temperature of the rapid charger and / or the battery
is outside the permissible range of 0°C to +45°C.
NOTICE
The rapid chargers are not suitable for outdooruse.
2.2. Selecting the bending tools
ROLLER'S Arco (Fig. 1a), ROLLER'S Akku-Arco (Fig. 1c)
Put a bending former (1) corresponding to the pipe size onto the square driver
(2). The mounting is designed such that the bending former can only be fully
fitted in one direction. Keep the back former (3) and the insert bolt (4) corre-
sponding to the pipe size at the ready.
ROLLER'S Arco 50 (Fig. 1b), Ø 35 – 50
Put a bending former (1) corresponding to the pipe size onto the square driver
35 – 50 (12). The mounting is designed such that the bending former can only
be fully fitted in one direction. Keep the back former (3), the support 35 – 50
(11) and the insert bolt (4) corresponding to the pipe size at the ready.
ROLLER'S Arco 50 (Fig. 1b), Ø 10 – 40
Insert square driver 35 – 50 (12) and square driver 10 – 40 (14) into the drive
unit. Put a bending former (Fig. 1a (1)) corresponding to the pipe size onto the
square driver 10 – 40 (14). The mounting is designed such that the bending
former can only be fully fitted in one direction. Keep the back former (3), the
support 10 – 40 (13) and the insert bolt (4) corresponding to the pipe size at the
ready.
NOTICE
In ROLLER'S Arco 50 the support 35 – 50 (11) or support 10 – 40 (13)
respectively should be attached above the back formers and bending
formers for all sizes. Up to and including sizes 24 R75 (¾" R75) the support
should also be attached below (15). This is hung in on one side to the
square collar of the square driver 10 – 40 (14) and on the other side with
the locating pin (16) in the outermost bore hole of the support at the
bottom (15) marked out in the housing (see 3.1.).
The drive unit gets damaged when bending without this support at the
bottom!
3. Operation
Use ear protection
3.1. Working procedure
Turn/slide setting ring/slide (7) to »L« (reverse). Press the safety inching switch
(8) whilst gripping the motor handle (9). The bending former turns clockwise
into its starting position against a fixed stop. Release the safety inching switch
if possible before reaching the fixed stop so that this starts up in run out, i.e.
the built-in slip clutch is not unnecessarily loaded. Turn/slide setting ring/slide
(7) to »R« (forward). Place pipe into bending former so that the pipe end
protrudes at least 10 mm beyond the driver (10). With the pipe sizes 22 – 50 mm,
the pipe must be pressed into the radius of the bending former. Apply the
corresponding back former (3) and push the insert bolt (4) into the appropriate
hole on the device.
NOTICE
In ROLLER'S Arco 50 the support 35 – 50 (11) or support 10 – 40 (13)
respectively should be attached above the back formers and bending
formers for all sizes. Up to and including sizes 24 R75 (¾" R75) the support
should also be attached below (15). This is hung in on one side to the
square collar of the square driver 10 – 40 (14) and on the other side with
the locating pin (16) in the outermost bore hole of the support at the
bottom (15) marked out in the housing.
When bending without this support at the bottom the drive unit gets
damaged!
Ensure here that the insert bolt (4) for the sizes up to 22 mm goes into the
left-hand locating hole (5) and from size 28 mm into the right-hand locating
hole (6).
Operate the safety inching switch (8) to bend the pipe. Towards the end of the
desired bend, only press the switch lightly. The end point can then be approached
slowly and therefore precisely. A scale is provided on each bending former
which together with the marking on the back former allows precise bending up

to 180°/ Arco 50 up to 90°. Be aware that various materials spring back differ-
ently. If a 180°/ Arco 50: 90° bend is produced and the end position is reached,
the slip clutch comes into action again. Release the safety inching switch
immediately. Turn/slide setting ring/slide (7) to »L« (reverse). Allow the bending
former to run back a few degrees until the pipe is unclamped by lightly pressing
the safetyinching switch (8). Pull out the insert bolt (4) and remove the bent
pipe. When bending on site, the bending former 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. When bending stainless steel pipes of pressfitting systems, it must
be ensured that the marking on the pipe made by the driver (10) does not lie
in the sealing area of the pressing joint.
3.2. Bending to measure
If a bend is to be in a certain place on the pipe, a length correction must be
made according to the pipe size. The correction dimension X specified in Fig.
2 must be considered for a 90° bend. The nominal dimension L must be short-
ened by the value X here. if, for example, with pipe size 22 with bending radius
77 the dimension L is to be = 400 mm, the mark must be made on the pipe at
319 mm. This mark must then be placed at the 0 mark on the bending former
as shown in Fig. 2.
3.3. Unit support ROLLER'S Arco, ROLLER'S Akku-Arco
A height-adjustable machine holder 3B (Art. No. 586100) or height-adjustable
machine holder WB (Art. No. 586150) for fixing to a workbench is available as
an accessory.
3.4. Bending lubricant
ROLLER'S bending spray (Art. No. 140120) ensures a continuous film of
lubricant for reduced force and even bending. High pressure-resistant, acid-free
Without HFC and therefore not harmful to the ozone layer.
3.5. Low Discharge Protection
ROLLER'S Akku-Arco is equipped with low discharge protection for the battery.
This switches off the power tool as soon as the battery needs to be recharged.
In this case remove the battery and charge with the ROLLER'S rapid charger.
4. Maintenance
4.1. Maintenance
WARNING
Pull out the mains plug or remove the battery before maintenance work!
Clean the power tool regularly especially when it has not been in use for a long
time. Keep the bending contours of the bending former (1) and back former (3)
clean. Clean plastic parts (e.g. housing) only with machine cleaner (Art. No.
140119) or a mild soap and a damp cloth. Do not use household cleaners.
These often contain chemicals which can damage the plastic parts. Never use
petrol, turpentine, thinner or similar products for cleaning. Make sure that liquids
never get onto or inside the power tool. Never immerse the power tool in liquid.
4.2. Inspection / maintenance
WARNING
Pull out the mains plug or remove the battery before maintenance and
repair work! This work may only be performed by qualified personnel.
The gear runs in a life-long grease filling and therefore needs no lubrication.
The ROLLER'S pipe bending machines with universal motor have carbon
brushes. These are subject to wear and must therefore by checked and changed
by qualified specialists or an authorised ROLLER customer service workshop
from time to time.
