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/outer edge of the back former allows precise
bending up to 180°/ Curvo 50 up to 90°. Be aware that various materials spring
back differently. If a 180°/ Curvo 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. 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
after
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/ 90° 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.
3.3. Unit support REMS Curvo, REMS Akku-Curvo
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
REMS bending spray (Art. No. 140120) 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.
3.5. Low Discharge Protection
REMS Akku-Curvo 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 REMS rapid charger.
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.
● Battery fl at or defective (REMS Akku-Curvo).
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.
● Battery fl at or defective (REMS Akku-Curvo).

4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the electric pipe bender, rapid charger and battery to an authorised REMS
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
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 REMS CleanM machine
cleaner (Art. No. 140119) or a mild soap and a damp cloth. Do not use house-
hold 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
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 REMS 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 REMS 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 REMS
customer service workshop.
● Have the carbon brushes or DC motor changed by qualifi ed personnel or an
authorised REMS customer service workshop.
● Charge the battery with the Li-Ion/Ni-Cd 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 REMS
customer service workshop.
● Have the device repaired/serviced by qualifi ed personnel or an authorised
REMS customer service workshop.
● Have the carbon brushes changed by qualifi ed personnel or an authorised
REMS customer service workshop.
● Charge the battery with the Li-Ion/Ni-Cd rapid charger or change the battery.
