The bending brake MUST be clamped or secured to a workbench before being used. Failure to do so can lead to personal injury or machine damage!

Basic Bending Operations

1.Open the bending brake and place the work- piece beneath the clamping angle.

2.Close the clamp assemblies until they lock. If the workpiece is to thick or too thin for the clamps, adjust the clamps according to

Clamp Adjustment on this page.

3.When the workpiece is secured in the bend- ing brake, lift the breaker bar levers to form the desired angle.

Clamp Adjustment

1.Without turning the clamping set screw, turn the adjusting nuts clockwise to adjust for thicker workpieces and counterclockwise to adjust for thinner workpieces. Adjust each clamp an equal amount.
