Item 5907
tool use and care
1.
Do not force the tool. use the correct tool for your application.
The correct tool will do the job better and safer at the rate for which it was designed.
2.
Store idle tools out of the reach of children and do not allow persons unfamiliar with the tool or these instructions to operate the tool.
Tools are dangerous in the hands of untrained users.
3.
Maintain tools. check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the tool’s operation. if damaged, have the tool repaired before use.
Many accidents are caused by poorly maintained tools.
4.
Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
5.

radius Bending
Radius bending is most commonly used to make cylinders and cones. Both shapes are formed by making a series of small, closely spaced bends in the workpiece.
For cylinders, the bends are evenly spaced, i.e. every bend is identical.
Figure i
Figure J
For cones, move one side of the stock out farther than the other for every bend.

1. Move the Cover (33) back and out of the way.
2. Coat the Pressing Rollers (24, 31 and 32) with general purpose grease for smooth operation.
Clean any dirt or excess grease from the Rollers.
3. Drop the Back Pressing Roller (24) by loosening the Roller Adjusting Knob (37). The Back Pressing
Roll (24) forms the radius in the material. The closer it is to the front Rollers, the smaller the radius will be. The Roller Adjustment Knob (37) adjusts the spacing of the Back Pressing Roller.
4. Test with scrap metal first, as metals have different bending characteristics.
5. Insert just the leading edge of your workpiece between the Upper Pressing Roll (32) and
Lower Pressing Roll (31), and tighten the roll bar gap Adjusting Screw (27) until the Roll
Bars are barely snug against the workpiece.
note:
For wire, insert the wire into the proper sized groove in the Upper Pressing Roller (32).
pan Forming
Pans of various sizes can be formed with a maximum lip (side) of 1″.
To form a pan:
1. Pre-measure and cut the material before bending.
Notch the corners according to the desired lip height.
6. Advance the Back Pressing Roll with the
Roller Adjustment Knob (37) as much as desired depending on the tightness of the roll to be accomplished. The tighter the roll, the more the knobs must be advanced.
7. Rotate the Handle (18) until the proper roll has been achieved. The material should feed itself through the rollers as you crank the Handle Assembly.
note:
To remove rolled material from Rollers without damaging the roll, loosen the Adjusting Screw, lift the Top Roller out of the groove and away from the
Brake, and slide the rolled material off the rollers.

3. Rotate the material 90º counterclockwise.
Allow the completed side to extend just beyond the Die. Bend the second side.
5. Rotate to the final side, and insert the workpiece between the dies. The formed sides will be on the outside of the Die.
Figure O
4. Repeat Step 3 for the third side.
Figure Q
6. Before bending, tap one corner nearer to the middle of the machine. This will allow the material to clear the Upper Braking Die when raised.
7. Bend the fourth side.
8. Using a block or piece of wood, tap the corner of material back into place.

pressing
1. Slide the Press Plate Bracket (8) of the Press Plate
Assembly into the receiver holes of the Apron. Note that the Press Plate (10) should be facing down.
2. Place the workpiece so that it is centered under the Press Plate.
3. Rotate the Handle (18) to press the workpiece.

troubleshooting problem
Bend is distorted.
Bend angle doesn’t match from end to end.
possible causes
Bending
1. Clamping pressure too tight.
2. Radius set back too close.
Likely Solutions
1. Adjust clamping pressure so that the workpiece has little or no clamping pressure at the outside edges of the tool.
2. Adjust the radius set back to at least 1-1/2 times the thickness of the material being bent, then readjust the clamping pressure.
Clamp misaligned.
Metal doesn’t cut evenly. Upper Blade bowed.
Measure angle at each end of bend, then adjust radius set back on each side as needed.
cutting
Turn Adjustment Nut clockwise to loosen or counter clockwise to tighten.
cautiOn! Do not overtighten
Supporting plate.
Overtightening Supporting
Plate will cause permanent distortion.
Blades don’t cut through metal.
1. Blades dull.
2. Blade distance needs adjustment.
1. Replace Blades.
2. Adjust distance of Lower Cutting Blade.
Rolled shape uneven from one end to the other end.
Rollers misaligned.
