which together with the marking/outer edge of the back former allows precise
bending up to 180°/ Arco 50 up to 90°. Be aware that various materials spring
back differently. 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 immediately. immediately. 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 pressfi tting 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 specifi ed in Fig.
2 must be considered for a 90° bend / 45° bend. The nominal dimension L must
be shortened by the value X here. If, for example, a 90° bend 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. Please bear in mind that the correction
dimension X is a recommended value and that it may be necessary to adapt
the correction dimension X to different pipe materials.
3.3. Unit support ROLLER'S Arco, ROLLER'S Akku-Arco 22 V
A height-adjustable machine holder 3B (Art. No. 586100) or height-adjustable
machine holder WB (Art. No. 586150) for fi xing to a workbench is available as
an accessory.
3.4. Bending lubricant
Safety data sheet, see www.albert-roller.de → Downloads → Safety data
sheets.
ROLLER'S bending spray (Art. No. 140121) ensures a continuous fi lm of
lubricant for reduced force and even bending. High pressure-resistant, acid-free
Without HFC and therefore not harmful to the ozone layer.
5. Faults
5.1. Fault: Bending former sticks during bending although the motor is running.
Cause:
● Pipe with too great wall thickness bent.
● Slip clutch worn.
● Carbon brushes worn (ROLLER'S Arco, ROLLER'S Arco 50).
● Battery fl at or defective (ROLLER'S Akku-Arco 22 V).
5.2. Fault: Bend is out of round.
Cause:
● Wrong bending former/back former.
● Worn back former.
● Damaged pipe.
5.3. Fault: Pipe slips out of the driver (10) during bending.
Cause:
● Driver bent or worn.
● Pipe does not protrude far enough out of the driver.
5.4. Fault: Device does not start.
Cause:
● Mains lead defective.
● Device defective.
● Carbon brushes worn (ROLLER'S Arco, ROLLER'S Arco 50).
● Battery (17) fl at or defective (ROLLER'S Akku-Arco 22 V).
● LED of the machine status check (Fig. 1c (18)) lights red
(ROLLER'S Akku-Arco 22 V).
● LED of the machine status check (Fig. 1c (18)) lights red due to overload
(ROLLER'S Akku-Arco 22 V).
● LED of the machine status check (Fig. 1c (18)) fl ashes red due to
exceeded motor temperature (ROLLER'S Akku-Arco 22 V).
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the electric pipe bender, rapid charger and battery to an authorised ROLLER
contract customer service workshop for inspection and periodic testing of
electrical devices at least once a year. 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.
4.1. Maintenance
WARNING 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 WARNING
Remove the mains plug or remove the battery before maintenance and
repair work! This work may only be performed by qualifi ed personnel.
The gear runs in a life-long grease fi lling 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 qualifi ed specialists or an authorised ROLLER customer service workshop
from time to time. In the battery-operated drive units, the carbon brushes of the
motor are subject to wear. These cannot be replaced; the DC motor must be
replaced.
Remedy:
● Only use approved pipes.
● Have the slip clutch replaced by qualifi ed personnel or an authorised ROLLER
customer service workshop.
● Have the carbon brushes or DC motor changed by qualifi ed personnel or an
authorised ROLLER customer service workshop.
● Charge the battery with the Li-Ion rapid charger or change the battery.
Remedy:
● Use the appropriate bending former/back former for the pipe.
● Change back former.
● Only use undamaged pipes.
Remedy:
● Change bending former (1).
● Place pipe in the bending former so that the pipe end protrudes at least 10 mm
beyond the driver.
Remedy:
● Have the mains lead changed by qualifi ed personnel or an authorised ROLLER
customer service workshop.
● Have the device repaired/serviced by qualifi ed personnel or an authorised
ROLLER customer service workshop.
● Have the carbon brushes or DC motor changed by qualifi ed personnel or an
authorised ROLLER customer service workshop.
● Charge the battery with the Li-Ion rapid charger or change the battery.
● Unsuitable battery inserted. Usable batteries, see 1.5.
● Wait a few seconds until the LED lights green.
● Wait until the LED lights green. Switch on the ROLLER cordless tool and let it
run without load to shorten the cooling time.
