To bend the pipe we need use hydraulic pipe bender, so what's the pipe bender?

The Hydraulic Pipe Bender is designed for bending thick-walled pipes (black iron, schedule 40 & 80, etc.).There are six different bending dies ranging from 12mm to 50mm. The Hydraulic Pipe Bender is not designed for bending thin-walled pipes.

ASSEMBLY

When this manual refers to a part number, it refers to the included Parts List.

1. Assembly of the lower plate:

a. First tum over the cylinder (#45) and remove the four hex bolts (#62) on the base of the cylinder.

b. Align the four holes of the lower plate (#64) with the holes of the cylinder base.

c. Affix with the hex bolts taken from the cylinder base.

2. Assembly of the upper plate:

a. When the lower plate is assembled, turn the cylinder over and insert two swagging blocks (#68) in the hole of the lower plate.

b. Place the upper plate (#54) over the swagging blocks and use the die cover shaft (#55) to secure the swagging block and the back oil cylinder seat (#58).

OPERATION

PIPE BENDER OPERATION

1. Tighten the release valve (#26) by turning clockwise

2. Loosen the vented oil bolt (#46).

3. Grease die cover (#56), swagging blocks (#68) and the pipe to be bent.

4. Lift the upper plate (#54) and affix the bending die to the end of the cylinder ram.

5. Turn the swagging blocks so their grooves face toward the pipe die (above).

6. To account for the pipe shortening during the bending process, make sure the pipe extends beyond the swagging blocks,

7. Set the swagging blocks closer together for short pipes, to ensure that the pipe extends beyond the swagging blocks.

8. Return the upper plate to original position (above) and use the advance pump to quickly advance the die. Note: Only one handle is included with the bending machine.

9. Use the forming pump to apply heavy pressure to bend the pipe to its desired angle

10. When finished bending, release the pressure by opening the release valve. The ram will automatically retreat. Lift the upper plate to take out the bent pipe.

11. Note: by using a combination of dies and swagging block settings you can achieve the desired angle .e.g. for a clean right angled finish start off by using the swagging blocks at the end of the pipe bender and work your way in.

MAINTENANCE

Maintain the tool with care. A tool in good condition is efficient, easier to control and will have fewer problems. Inspect the tool components periodically, Repair or replace damaged or worn components. Lubricate tool when required.

Follow instructions for lubricating and changing accessories.

Keep the tool handles clean, dry and free from oil/grease at all times.

When servicing, use only identical replacement parts. Only use accessories intended for use with this tool.

Replace damaged parts immediately.

The oil level should be kept constant at about 1 .2lt of quality hydraulic oil. Too much oil will force the surplus oil to leak from the cylinder seals and possible damage them, Not enough oil will cause loss of power as air will be sucked in, causing a drop in pressure.

Periodically clean and maintain the machine. Use clean, filtered oil, making sure the filter (#30) is cleaned regularly.
