3. Operation
3.1. Working procedure
Turn changeover switch (7) to »L« (return). Press inching switch (8) while grip-
ping the motor handle (9) at the same time. The bending former turns clock-
wise 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« (advance). Place pipe into bending former
so that the pipe end projects at least 10 mm beyond the driver (10). With the
”), the pipe must be pressed into the radius of
pipe sizes 22 to 28 mm ( 3 / –1 1 /
4 8
the bending former. Fit the appropriate back former (3) and then the insert bolt
(4). Ensure here that the insert bolt (4) for the sizes up to 22 mm (
to 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 approa-
ched slowly and thereby precisely. A scale is provided on each bending for-
mer, together with the mark on the back former, ensures precise manufacture
of arcs of up to 180°. Please bear in mind here that the various materials (soft
and hard copper pipe, soft and hard steel pipe) differ in their springiness. If a
180° bend is produced and reaches the end position, the slipping clutch comes
into action again. Release the inching switch immediately. Turn setting ring
(7) to »L« (return). Allow the bending former to run back a few degrees until
the pipe is unclamped by light pressure on the inching switch (8). Draw the in-
sert bolt (4), pull away the back former (3) 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
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 before any servicing and repair work. This work must
be carried out solely by specialists or persons familiar with the unit.
4.1. Maintenance
The ROLLER'S Arco is 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 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 "6. Action in Case of Trouble".
