2.1. ROLLER'S Convex Fig. 1 – 3
Place the bender drive (4) on a fi rm, level base. Make sure that there is enough
room for the fully assembled pipe bender and the pipe to be bent. Insert the
lower roller holder (1) into the lower groove of the bender drive (4) so that the
feet (16) are facing down and the bolt (5) can be inserted. Secure the bolt (5)
with the spring loaded pin (6). Insert the upper roller holder (2) into the upper
groove of the bender drive (4) so that the angle marking (14) is legible, fi x with
the bolt (5), secure the bolt with the spring-loaded pin (6). Insert the rollers (7)
according to the pipe size, see scale (17), into the holes between the roller
holders (1 and 2). To bend composite pipes with a diameter of 75 mm, insert
the 75 mm diameter back formers (accessory) between the roller holders (1
and 2) in place of the rollers (7). The roller bearing plate of the upper roller
holder (2) can be moved to the side if necessary, e.g. to form a dogleg (22).
The rollers must always be inserted into the holes of the upper and lower roller
holder (1 and 2) for bending. Select the suitable bending former for the pipe
size (10) and fi t it on the bender drive (4). Push the advance lever (11) onto
the bender drive (4). Open the locking screw (12) about 1 turn. Close the return
valve (13) by turning in and screw hand tight.
2.2. ROLLER'S Polo Fig. 4 – 6
Place the back former support (3) on the bender drive (4) so that the back
formers (7) for the desired pipe size are facing towards the rack (8). The back
formers are marked with the pipe size. Fix the back formers (3) with the wing
nut (9). Select the suitable bending former (10) for the pipe size and fi t it on the
rack (8). Press down the advance lever (11) in the direction of the arrow (18)
and push back the bending former (rack) to the rear stop. Release the advance
lever.
Device for reverse bend Fig. 5 (accessory)
Place the bending former holder (19) on the bender drive (4) so that the holder
for the bending former is facing towards the rack (8). Fix the bending former
holder (19) with the wing nut (9). Fit the back former support holder (20) to the
rack (8). Fix the back former support holder (20) with the wing nut. Place the
back former support (3) in the back former support holder (20) so that the back
formers (3) for the desired pipe size are facing towards the bending former
holder (19). The back
holder (19). The backformers (7) are marked with the pipe size. Fix the back
holder (19). The backformers (7) are marked with the pipe size. Fix the back

for the pipe size and fi t it on the bending former holder (19). Press down the
advance lever (11) in the direction of the arrow (18) and push back the back
former support (rack) to the rear stop. Release the advance lever.
Place the back former support (3) on the bender drive (4) so that the back
formers (7) for the desired pipe size are facing towards the advance lever (8).
The back formers are marked with the pipe size. Fix the back former support
(3) with the wing nut (9). Select the bending former (10) suitable for the pipe
size, align the square pin of the advance plunger (8) to the square pin of the
bending former (10) by swivelling the advance lever and fi t the bending former
onto the advance plunger (8). Close the return valve (13) by turning in and
screw hand tight. The bender drive (4) can be turned approx. 360°. Then the
advance lever (11) can be positioned to the bending former (10) and back
former support (3) as required.

Place the bending former holder (19) on the bender drive (4) so that the holder
for the bending former is facing towards the rack (8). Fix the bending former
holder (19) with the wing nut (9). Fit the back former support holder (20) to the
rack (8). Fix the back former support holder (20) with the wing nut. Place the
back former support (3) in the back former support holder (20) so that the back
formers (3) for the desired pipe size are facing towards the bending former
holder (19). The back formers (7) are marked with the pipe size. Fix the back
former support (3) with the wing nut. Select the suitable bending former (10)
for the pipe size and fi t it on the bending former holder (19). Open the return
valve by turning the screw (13) anti-clockwise. Close the return valve by turning
the screw (13) clockwise.
Lift up the upper roller support (2). Insert the pipe between the rollers (7) and
the bending former (10). Close the upper roller support (2). Move the advance
lever (11) up and down several times until the pipe has reached the desired
bending angle. Open the return valve (13) by about 1 turn, the bending former
(10) returns to the starting position with the pipe bend. Lift up the upper roller
holder (2) and remove the bent pipe. The bending formers St 1" to St 2" have
a hexagon head screw. This can be used to press out a pipe jammed in the
bending former.
