Weighted effective
value of acceleration
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
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 (Fig. 1c (17))
T
Total discharging by undervoltage
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", see graduated charging
state display. 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 manufac-
turer 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
NOTICE
Charge the battery before use. Recharge Li-Ion batteries regularly to avoid
their total discharge. The rechargeable battery will be damaged by total
discharge.
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.
Machine status check, REMS Akku-Curvo 22 V
REMS Akku-Curvo 22 V is equipped with an electronic machine status check
(Fig. 1c (18)) by a 2-colour green/red LED. The LED lights green when the
battery is fully or still suffi ciently charged. The LED lights red when the battery
must be charged. If this status occurs during bending, bending must be completed
with a charged Li-Ion battery. The LED lights red and the REMS Akku-Curvo
22 V switches off if overloaded. After a short dwell time, the LED lights green
again and bending can be continued. The LED fl ashes red if the motor temper-
ature has been exceeded. After a cooling time, the LED lights green again and
bending can be continued. The cooling time is reduced when the REMS Akku-
Curvo 22 V is operated in idle mode. The LED lights red if an impermissible
battery has been inserted. If the REMS Akku-Curvo 22 V is not being used, the
LED goes out after approx. 2 hours but comes on again when the device is
switched back on.

Graduated charging state display (Fig. 1c (19)) of the Li-Ion 21.6 V battery
The graduated charging state display shows the charging state of the battery
with 4 LEDs. At least one LED lights for a few seconds after pressing the key
with the battery symbol. The more LEDs that light green, the higher the charging
state of the battery. If a LED fl ashes red, the battery must be charged.
Rapid charger Li-Ion (Art. No. 571585)
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
NOTICE
The rapid charger is not suitable for using outdoors.
2.2. Selecting the bending tools
REMS Curvo (Fig. 1a), REMS Akku-Curvo 22 V (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
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
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
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
