Use for:

• Rolling / bending metal tube (measured by outside diameter).

• Equipped with .5 inch, .75 inch, 1 inch, and 1.25 inch diameter die sets.

• Thin-wall tube is this machine’s forte.

Do Not Use for:

• Wrong tube sizes with a given die set. Die sets are specific to tube size.

• Do not use for pipe. Tube is sized by outside diameter, pipe by its theoretical inside diameter.

Hazard Analysis

• Eye protection required. (Metal can snap while bending, and flakes of rust, mill scale, or paint can become airborne.

• Cuts / Scrapes from sharp cut edges of workpiece. Use of gloves is acceptable when using this machine.

• Cuts / Scrapes / bruises or worse if care is not taken to prevent metal stock from slipping during the bending process, possibly becoming airborne due to high pressure.

• Pinched fingers or skin.

		Eye protection required!

Notes and Best Practices

• Die Set consists of 3 Parts:

- One Forming Die

- One Pressure Die (Follow Bar)

- One U-Block (A small square block that retains the workpiece.)

• The Forming Die does not rotate. The Follow Bar rolls around the die. A stationary die makes it easier to control the location of the bend your workpiece.

• Our machine is equipped with a foot pedal control. (The manufacturer’s instructions and the YouTube instructions show a hand control.)
