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.
Bespoke bending (Fig. 2)
On the outer side of the bending formers (7) two markings (12) are indicated,
which allow for precise bending. At this point the bespoke mark is to be made
at the marking (12) over the centre at which the 90° bend should be completed.
For guidance of the bending angle, angle markings (11) are indicated on the
upper roller holder (2).
NOTICE
To ensure the functional reliability and to avoid hydraulic oil escaping, the locking
screw (9) must be tightly locked off after completion of bending and for trans-
porting of the bending drive.

4. Maintenance
4.1. Maintenance
Check the advance lever (8) regularly for damage, change damaged advance
lever. Clean the tool regularly especially when it has not been in use for a long
time. Keep the bending contours of bending former (7) and rollers (6) clean.
Use machine cleaner (Art.-No. 140119) or mild soap and a damp cloth for
cleaning. Do not use household cleaners. These often contain chemicals which
can damage the plastic parts. Never use petrol, turpentine, thinner or similar
products for cleaning.
4.2. Inspection/Repair
This work may only be performed by qualified personnel.
Check hydraulic oil (Fig. 3), refill hydraulic oil (Art. No. 091026) if necessary.
Do not overfill, otherwise hydraulic oil will leak during work.
Remedy:
● Close the return valve by turning in and tighten hand tight.
● Refill hydraulic oil (Fig. 3 and 4.2).
● Open return valve (10) and move the pump lever up and down several times
until the air has escaped.
● Have hydraulic pipe bender checked/repaired by an authorised ROLLER
customer service workshop.
Remedy:
● Refill hydraulic oil (Fig. 3 and 4.2).
● Insert rollers according to the pipe size, see scale (14), into the holes
between the roller holders (1 and 2).
