Safety instructions for oil-hydraulic pipe benders, one-hand pipe benders, oil-hydraulic hand pipe benders
CAUTION

Read all the safety notes, instructions, illustrations and technical data which come with this tool. Failure to heed the safety notes and instructions can lead to severe injuries.
Keep all safety notes and instructions for the future.

• Do not use the tool if it is damaged. There is a danger of accident.
• Do not reach between the pipe, rollers/back formers (7) and the bending former (10) during bending. There is a risk of injury.
• Protect persons accompanying the work against the moving pipe during bending. There is a risk of injury.
•  Be careful when bending with REMS Python and REMS Hydro-Swing. These develop a high bending force. There is a danger of injury in case of improper use.
• Do not lift or carry the REMS Python by the attached advance lever (11). The advance lever is only inserted but not secured. The bender drive (4) can come loose from the advance lever (11) and fall off. There is a risk of injury.

REMS Python 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.

REMS Swing 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 backformers (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). 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.

REMS Hydro-Swing Fig. 7 – 8

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.

Operation

REMS Python Fig. 1 – 3

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.
There is an angle marking (14) on the upper roller holder (2) for orientation for the bending angle.

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.

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 The bending formers (10) and the back formers (7) of REMS Swing are made of glass-fi bre-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.

REMS Hydro-Swing Fig. 7 – 8

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 The bending formers (10) and the back formers (7) of REMS Hydro- Swing are made of glass-fi bre-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.
The aluminium bending formers Ø 15, 18, 22 mm must be used for bending stainless steel pipes and carbon steel pipes, see fi g. 8.

Bending to size Fig. 9

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.

Maintenance

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. Use REMS CleanM (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. Never immerse the pipe bender in liquid.

Inspection/Repair

This work may only be performed by qualifi ed personnel.
In REMS Python, check hydraulic oil (Fig. 2), refi ll hydraulic oil (Art. No. 091027) if necessary. Do not overfi ll, otherwise hydraulic oil will leak during work.

Behaviour in the event of faults
