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.
Attention:
The indicated weighted effective value of acceleration can differ
during operation 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
Pay attention to mains voltage! Check whether the voltage specified on the
rating plate matches the mains voltage before connecting the drive machine
or the rapid charger. Only operate the electrical device on the mains via a 30 mA
fault current protection device (FI switch) on building sites, out doors or similar
types of installation.
The battery and spare batteries delivered with the ROLLER’S Akku-Arco are
not charged. Charge the batteries before using for the first time. Only use the
ROLLER’S rapid charger (565220) for charging. When the battery is inserted
in the rapid charger the pilot light on the rapid charger flashes. The pilot light
stops flashing and lights steadily after approx. 1 hour meaning that the battery
is charged. The battery only reaches its full capacity after several charging
cycles.
2.2. Selecting the bending tools
ROLLER’S Arco, ROLLER’S Akku-Arco
Put a bending former (1) (Fig. 1) corresponding to the pipe size onto the square
(2). The mounting is designed such that the bending former can only be fully
fitted in one direction. Place in readiness the back former (3) sui table for the
pipe size and the insert bolt (4).
ROLLER’S Arco 50, Ø 35 – 50
Put a bending former (1) (Fig. 1) corresponding to the pipe size onto the square
(12). The mounting is designed such that the bending former can only be fully
fitted in one direction. Place in readiness the back former (3) sui table for the
pipe size and the insert bolt (4). Insert the appropriate sized back former (3),
the support (11) and the insert bolt (4).
ROLLER’S Arco 50, Ø 10 – 40
Remove adaptor block (12) and replace with adaptor block (14) into the drive
unit. Put a bending former (1) (Fig. 1) corresponding to the pipe size onto the
square (14). The mounting is designed such that the bending former can only
be fully fitted in one direction. Insert the appropriate sized back former (3), the
support (13) and the insert bolt (4).
When using the ROLLER’S Arco 50, the support (11) and (13) respec tively
should be attached above the bending and back formers, for all sizes. Up
to and including sizes 24 R75 (¾” R75), the support (15) should also be
attached below. This is mounted on one side on the adaptor block collar
(14), and on the other side with the locating pin (16) in the outermost bore
hole of the support (15) marked out in the housing (see 3.1.).
The drive unit gets damaged when bending without this support!
3. Operation
3.1. Working procedure
Turn changeover switch (7) to »L« (reverse). Press inching switch (8) while
gripping the motor handle (9) at the same time. The bending former turns
clockwise into its starting position in which the slipping clutch is effective.
Release the inching switch
immediately.
Do not put unnecessary load on the
clutch. Turn changeover switch (7) to »R« (forward). Place pipe into bending
former so that the pipe end projects at least 10 mm beyond the driver (10).
With the pipe sizes 22 to 50 mm, the pipe must be pressed into the radius of
the bending former. Lower the insert bolt (4) through the matching back former
(3) and into the corresponding hole bored in the machine.
When using the ROLLER’S Arco 50, the support (11) and (13) respec tively
should be attached above the bending and back formers, for all sizes. Up
to and including sizes 24 R75 (¾” R75), the support (15) should also be
attached below. This is mounted on one side on the adaptor block collar
(14), and on the other side with the locating pin (16) in the outermost bore
hole of the support (15) marked out in the housing (see 3.1.).
The drive unit gets damaged when bending without this support!
Ensure here that the insert bolt (4) for the sizes up to 22 mm (¾”) goes into the
left-hand locating hole (5) and for larger sizes into the right-hand hole (6).
Operate the inching switch (8) to bend the pipe. Towards the end of the required
bend, only press the switch lightly, so that the final point is approached slowly
and thereby precisely. A scale is provided on each bending former, together
with the mark on the back former, ensures precise manufacture of arcs of up
to 180° / Arco 50 up to 90°. Be aware that various materials spring back differ-
ently. If a 180° bend / Arco 50: 90° bend is produced and reaches the end
position, the slipping clutch comes into action again. Release the inching switch
immediately.
Turn changeover switch (7) to »L« (reverse). Allow the bending
former to run back a few deg rees until the pipe is unclamped by light pressure
on the inching 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. While bending
stainless steel pipes of pressfitting systems one must pay attention that the
mark at the pipe caused by the driver (10) does not lie in the sealing area of
the pressing joint.
3.2. Bending to size
If a bend is required at a certain point on the pipe, a lenght correction must be
made to suit the pipe size.
For a 90° bend, the correction dimension X given in Fig. 2 must be taken into
account. The set dimension L must be reduced by the amount X here. If the
dimension L should be 400 mm for the pipe size 22, the dimension line must
be made on the pipe at 320 mm. This line is then – as shown in Fig. 2 – to be
aligned with the 0-mark on the bending former.
3.3. Unit support ROLLER’S Arco, ROLLER’S Akku-Arco
Vertically adjustable unit supports on tripod (Art.No. 586100) and for mounting
on the work bench (Art.No. 586150) available as accessories.
4. Maintenance
Pull out the mains plug and remove the battery before maintenance and repair
work! This work must be carried out solely by specialists or persons familiar
with the unit.
4.1. Maintenance
ROLLER’S Arco, ROLLER’S Arco 50 and ROLLER’S Akku-Arco are maintenance-
free. The gearbox has a permanent grease filling and therefore requires no
lubrication.
4.2. Inspection/Servicing
The motor of the ROLLER’S Arco and ROLLER’S Arco 50 has carbon brushes.
These are subject to wear and must therefore be checked periodically and
replaced if necessary. To do so, unscrew the 4 screws on the motor handle
about 3 mm, pull the motor handle back and remove the two covers from the
motor housing. See also ”5. Action in Case of Trouble“.
5. Connection
In the ROLLER’S Akku-Arco make absolutely sure that the plus pole on the
motor (plastic base of the connecting tab with lug) is connected to switch terminal
1 with the red wire.
6. Trouble
6.1. Trouble:
Bending former stops during bending although the motor is
running.
Cause:
●
Pipe being bent has walls too thick.
●
Slipping clutch worn.
●
Carbon brushes worn.
●
Battery empty (ROLLER’S Akku-Arco).
