WARNING! Read these instructions 

and the accompanying safety booklet 

carefully before using this equipment. If 

you are uncertain about any aspect of using this 

tool, contact your RIDGID distributor for more 

information.

Failure to understand and follow all instructions 

may result in electric shock, 

fi

 re, and/or serious 

personal injury.

SAVE THESE INSTRUCTIONS!

Assembling

1.  a. 1 1/4”, 2” and 3” machines.

  Place the bending frame with its supports on the 

fl

 oor and slip the ring 

over the front of the pump cylinder.

  Place the U-bracket through the holes in the ring block of the bending 

frame. The pump cylinder and pipe bending frame are now 

fi

 xed in the 

correct position.

1.   b. 4” machine.

-  Place the base beam on the 

fl

 oor.

-  Place the lower wing on the base beam.

-  Place the bending-pump on the base beam, hook the lower wing 

into the pump and secure the pump at the rear with two M10 bolts.

-  Place the corner-supports and where applicable the bending-

former that you will be using, on the lower wing.

-  Place the upper wing on the corner-supports and hook it into the 

pump.

- Insert 

the 

fi

 xing-pins through the wings and the corner-supports.

2.  Mount a bending former according to the diameter of the pipe to be 

bent, on the ram top. The corner supports must be placed between, or 

on the bending frame. They are fastened by means of the 

fi

 xing-pins. 

The holes in the frame allow the corner supports to be adjusted to the 

desired outside diameters. The holes are marked accordingly. Ensure 

that the 

fi

 xing pins for corner supports are properly 

fi

 tted through both 

wings or through the bending frame to prevent damage.

Bending

1. The 

fi

 lling cap is pierced for air release. Whenever the bending 

machine is transported this 

fi

 lling cap must be tightly closed, but 

released a little when in use.

2.  Before bending, the pipe should be slightly greased. The pipe is then 

slipped between the corner supports and bending former. The relief 

spindle must be locked tightly. By moving the handle up and down the 

pump is put into operation. The ram moves out and the pipe is bent. 

The bending operation should be continued until the desired curve 

is reached but not further than the bending former curve. It should 

be remembered that the pipe will spring back a little according to the 

quality of the pipe. This must be established by experience.

3.  As soon as the pipe reaches its required shape, loosen the relief 

spindle and the ram withdraws automatically. Disconnect one of the 

corner supports and the pipe can be removed. The models equipped 

with an open frame have the advantage that the bent tube can 

removed easier, especially long pieces of tubes with several bends, 

thus saving a lot of time.

4.  If a bend has been bent too far this can be corrected by means of 

the straightener. The ram must be reversed and the tube turned over 

against the corner supports. The straightener is placed on the ram top 

and the bend can now be pushed back to its desired shape. On the 

1 1/4” bending machine a bend of 90° cannot normally be corrected. 

This also applies to the 3” machine for 2 1/2” and 3”, for the 4” 

machine for 3” and 4” pipes.

5.  For 3” and 4” model only.

  When bending 2 1/2”, 3” and 4” pipes an extension piston should be 

applied to the ram when the tube has been bent past 75°. The stroke 

of the ram is not enough to bend a 90° bend in one operation.

6.  1 1/4”, 2”, 3”, 4” electro-hydraulic pipe bending machines.

  The electro-hydraulic pipe bending machines are equipped with a 

single phase 115 V, 220 V, AC or 380 V 3 phase motor. The motor has 

a special safety switch. Once the motor is running the movement of 

the ram is controlled by means of a relief spindle which can be either 

opened or closed. The motor does not have to be switched off. The 

machine also features a pressure safety valve. This is factory set so 

that heavy wall pipe (steam pipe) can be bent without any problem. 

The pressure safety valve is situated in the pump housing and can 

only be set by means of a manometer.

Bending of Hairpin Shapes of 180°

For this, additional accessories are required which can be delivered on 

request.

Assembling

1.  See under assembling bending machine.

2.  The bending former (180°) according to the size of the pipe to be 

bent, is placed on the ram. Next, the plates (spare frames) with 3 rolls 

(diabolos) are adjusted between or in the frame. The 

fi

 xing-pins for 

corner supports must be put in the holes 1 1/4” through the center 

lock; the removable diabolo must be removed and the pipe to be bent 

run through. The pipe must now touch the center diabolo with one side 

and the 180° bending form with the other side. Bending can now be 

started.

Bending

1.  See under bending.

2.  If the bending is more than 90°, the ram must be reversed, by 

releasing the relief spindle. Adjust the removable diabolos and bend 

up to 180°. To remove the bent pipe, see Bending.

Maintenance

The bender is delivered with a 

fi

 lled oil container. However, the oil level 

must be checked regularly as otherwise the stroke of the ram will become 

too short. Oil must always be level with the bottom of the 

fi

 lling cap. If oil 

needs to be added, use only hydraulic oil.

Caution

1.  Ensure that corner supports are always adjusted symmetrically in 

the holes, according to the size of the pipe to be bent. If not placed 

properly, the ram instead of the pipe may be bent and the machine 

badly damaged.

2.  Also take care that 

fi

 xing-pins for corner supports are properly 

fi

 tted 

through the holes in the upper and under wing of the bending frame, 

and all the way through on the open bending frame.

3.  The ram must not be moved out beyond the groove mark.

Faults which may occur and how they can be corrected

Numbers in brackets refer to electric machines.
