NOTICE NOTICE
To ensure functional reliability and to prevent hydraulic oil leakage, the locking
screw (12) must be closed after bending has been completed and for transport
of the bender drive.
3.2. REMS Swing Fig. 4 – 6
Turn the back formers (7) so that radius on the back former corresponding to
the pipe size is on the side facing the bending former (10). Insert the pipe
between the bending former (10) and the back formers (7). Push the advance
lever (11) several times opposite to the direction of the arrow (18), until the pipe
has reached the desired bending angle. Push the advance lever (11) in the
direction of the arrow (18) and push back the bending former, if necessary with
the bent pipe. Remove the pipe.
NOTICE NOTICE
The bending formers (10) and the back formers (7) of REMS Swing are made
of glass-fibre-reinforced polyamide. This plastic have very good slide properties,
is very strong and heat resistant up to approx. 150 °C. Annealed copper pipes
must be cooled down below this temperature.
3.3. REMS Hydro-Swing Fig. 7 – 9
Turn the back formers (7) so that radius on the back former corresponding to
the pipe size is on the side facing the bending former (10). Insert the pipe
between the bending former (10) and the back former (7). 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 and the bending
former (10) returns to the starting position with the pipe bend. Remove the pipe.
NOTICE NOTICE
The bending formers (10) and the back formers (7) of REMS Hydro-Swing are
made of glass-fibre-reinforced polyamide. This plastic have very good slide
properties, is very strong and heat resistant up to approx. 150°C. Annealed
copper pipes must be cooled down below this temperature.

5. Behaviour in the event of faults

5.1. Fault: Bending former (10) does not advance despite moving the advance lever (11) up and down several times.
Cause:
● Return valve (13) not closed (REMS Python, REMS Hydro-Swing).
● Not enough hydraulic oil in the system.
● Air in the system (REMS Python).
● Advance lever (11) not pushed properly (REMS Swing).
● Overpressure valve responds (REMS Python, REMS Hydro-Swing).
● Pipe bender defective.
5.2. Fault: 90° bend cannot be fully made.
Cause:
● Not enough hydraulic oil in the system.
● Rollers (7) in wrong position between roller holders (1 and 2)
(REMS Python).
● Back former support (3) fitted incorrectly (REMS Swing,
REMS Hydro-Swing).
● The strength of the pipe to be bent is too high.
● Pipe bender defective.
5.3. Fault: No useful bend.
Cause:
● Pipe size does not correspond to the bending former (10) and/or the rollers/
back formers (7).
● Rollers (7) in wrong position between roller holders (1 and 2)
(REMS Python).
● Back former support (3) fitted incorrectly (REMS Swing,
REMS Hydro-Swing).
● Pipe is unsuitable for bending.
5.4. Fault: Advance lever (11) cannot be pushed or only with difficulty (REMS Swing).
Cause:
● Pipe is unsuitable for bending.
● One-hand pipe bender defective.
12
The aluminium bending formers Ø 15, 18, 22 mm must be used for bending
stainless steel pipes and carbon steel pipes, see fig. 9.
3.4. Bending to size Fig. 10
There are 2 markings (15) on the outside of the bending formers (10) which
allow exact bending to size. To do this, the dimension mark at which the 90°
bend is to end must be placed against the marking (15) over the centre.
4. Maintenance
4.1. Maintenance
In the REMS Python, check the advance lever (11) regularly for damage,
change damaged advance lever. REMS Swing and REMS Hydro-Swing are
maintenance-free.
Clean the pipe bender regularly especially when it has not been in use for a
long time. Keep the bending contours of bending former (10) and rollers/back
formers (7) clean. Only clean plastic parts with a suitable cleaning agent or
mild soap and a damp cloth. 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. Never immerse the pipe
bender in liquid.
4.2. Inspection/Repair
CAUTION CAUTION
This work may only be performed by qualified personnel.
In REMS Python, check hydraulic oil (Fig. 2), refill hydraulic oil (Art. No. 091027)
if necessary. Do not overfill, otherwise hydraulic oil will leak during work.
Remedy:
● Close the return valve (13) by turning in and screw hand tight.
● Refill hydraulic oil (in REMS Python (Fig. 2 and 4.2. Inspection/repair). Have
the REMS Hydro-Swing checked/repaired by an authorised REMS customer
service workshop.
● Open return valve (13) by about 1 turn and move the advance lever (11) up
and down several times until the air has escaped.
● Push the advance lever (11) several times, as far as possible, in the opposite
direction to the arrow (18).
● Pipe is unsuitable for bending. Only use approved pipes.
● Have the pipe bender checked/repaired by an authorised REMS customer
service workshop.
Remedy:
● Refill hydraulic oil (in REMS Python (Fig. 2 and 4.2. Inspection/repair). Have
the REMS Hydro-Swing checked/repaired
by an authorised REMS customer service workshop.
● Insert the rollers (7) according to the pipe size, see scale (17), into the holes
between the roller holders (1 and 2).
● Fit back former support as described in 2.2. or 2.3.
● Only use approved pipes.
● Have the pipe bender checked/repaired by an authorised REMS customer
service workshop.
Remedy:
● Use bending formers and/or rollers/back formers according to the pipe size.
● Insert rollers according to the pipe size, see scale (17), into the holes
between the roller holders (1 and 2).
● Fit back former support as described in 2.2. or 2.3.
● Only use approved pipes.
Remedy:
● Only use approved pipes.
● Have the one-hand pipe bender checked/repaired by an authorised REMS
customer service workshop.
