Weighted effective
value of acceleration < 2.5 m/s²
K = 1,5 m/s²
The indicated weighted effective value of acceleration has been measured
against standard test procedures and can be used by way of comparison with
another device. The indicated weighted effective value of acceleration can also
be used as a preliminary evaluation of the exposure.
CAUTION CAUTION
The indicated weighted effective value of acceleration can differ during opera-
tion from the indicated value, dependent on the manner in which the device is
used. Dependent upon the actual conditions of use (periodic duty) it may be
necessary to establish safety precautions for the protection of the operator.

2. Preparations for Use

2.1. Electrical connection
WARNING
Caution: Mains voltage present! Before connecting the electric pipe bending
machine or the rapid charger, check whether the voltage given on the rating
plate corresponds to the mains voltage. On building sites, in a wet environment,
indoors and outdoors or under similar installation conditions, only operate the
electric pipe bending machine on the mains with a fault current protected switch
(FI breaker) which interrupts the power supply as soon as the leakage current
to earth exceeds 30 mA for 200 ms.
Rechargeable batteries
NOTICE
Always hold the battery (17) upright when inserting it in the drive unit or the
rapid charger. If inserted at an angle it can cause damage to the contacts and
result in a short circuit which damages the battery.
Total discharging by undervoltage
The Li-Ion batteries may not drop below a minimum voltage because otherwise
the battery could be damaged by "total discharge". The cells of the REMS Li-Ion
battery are delivered pre-charged to approx. 40 %. Therefore the Li-Ion batteries
must be charged before use and recharged regularly. Failure to observe this
regulation of the cell manufacturer can lead to damage to the Li-Ion battery by
total discharging.
Total discharging due to storage
If a relatively low charged Li-Ion battery is stored, self discharging can lead to
total discharge damage of the battery after longer storage. Li-Ion batteries must
therefore be charged before storing and recharged every six months at the
latest and charged again before use.
NOTICE
Charge the battery before use. Recharge Li-Ion batteries regularly to avoid

Only use a REMS 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
fl ashes to indicate that the battery is charging. The green light stops fl ashing
and remains on to signal that the battery is fully charged. If the red control lamp
fl ashes, 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 +40°C.
NOTICE
The rapid chargers are not suitable for outdooruse.
2.2. Selecting the bending tools
REMS Curvo (Fig. 1a), REMS Akku-Curvo (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
fi tted in one direction. Keep the back former (3) and the insert bolt (4) corre-
sponding to the pipe size at the ready.
REMS Curvo 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 fi tted 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.
REMS Curvo 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 fi tted 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 REMS Curvo 50 the support 35 – 50 (11) or support 10 – 40 (13) respec-
tively 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 fi xed stop. Release the safety inching switch
if possible before reaching the fi xed 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 REMS Curvo 50 the support 35 – 50 (11) or support 10 – 40 (13) respec-
tively 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
