Your Ironworker may include a bar/plate shear as a standard fea-

ture. When maintained within tolerance, the bar/plate shear will

provide a distortion and burr free shear cut to mild steel bar or

plate stock. Shear blades are wearing parts and need to be main-

tained or replaced over time. When worn or chipped, shear blades

must be replaced. Observe the following procedure when main-

taining the Ironworker bar shear station.

Turn off power to machine by depressing the red stop/off

button and lockout upstream power at the main electrical

panel.

Remove and replace stationary blade:

1. Remove the material hold-down assembly from the Ironworker

frame by removing the return spring and bolts that secure the as-

sembly to the Ironworker frame.

2. Remove blade bolts located under the feed table. Remove the sta-

tionary blade.

3. With blade removed, clean blade pocket of any dirt or debris.

4. Your shear blades have multiple cutting surfaces that can be ipped

and rotated prior to full replacement of the part. Rotate the station-

ary blade to new cutting surface and reinstall in blade pocket.

5. Tighten the stationary blade back into the blade pocket.

Remove and replace moving blade:

1. Remove the drop-off guard from the rear of the Ironworker frame.

2. Power on the machine and inch the moving center down to reveal

blade bolts for the moving blade.

3. With bolts exposed, turn machine off and disconnect from power

source.

4. Remove blade bolts and remove blade from the blade pocket.

5. With blade removed, clean blade pocket of any dirt or debris.

6. Your shear blades have four cutting surfaces that can be used prior

to full replacement of the part. Rotate the movable blade to new

cutting surface and reinstall in blade pocket.

7. Tighten the movable blade back into the blade pocket.

8. Replace the drop-off guard to the rear of the frame.

9. Return the machine to power and turn on to automatically return

the moving center to its neutral position.

10. With a feeler gauge, check shear blade for correct operating clear-

ance.

• Maintain .010 clearance between xed and movable shear

blades on 40, 50, 55, 60 and 65 Ton models at all times.

• Maintain .015 clearance between xed and movable shear

blades on 75, 100, 100D, E110, E110 / 65 and 120 Ton mod-

els at all times.

11. Adjust tolerance of shear blades by relieving the locking nuts that

secure the gib-pins to the Ironworker frame. Once loose, rotate gib-

pins to push the operating center against the frame. Gap the angle

and bar shear blades with the specied clearance and tighten the

gib-pin lock nuts.

Failure to maintain proper clearance will result in lower qual-

ity cuts, damage to blades, blade pockets and the potential to

damage the Ironworker frame.

12. Replace and secure guarding removed in the maintenance proce-

dure.

13. Replace the material hold-down assembly to the Ironworker frame.

Bar Shear

Your Ironworker may include an angle iron shear as a standard

feature. When maintained within tolerance, the angle iron shear

will provide a distortion and burr free shear cut to mild steel angle

iron. Angle iron shear blades are wearing parts and need to be

maintained or replaced over time. When worn or chipped, shear

blades must be replaced. Observe the following procedure when

maintaining the Ironworker bar shear station.

Turn off power to machine by depressing the red stop/off

button and lockout upstream power at the main electrical

panel.

Remove and replace stationary blade:

1. Remove the material hold-down assembly from the Ironworker

frame by removing the bolts that secure the guard / hold-down

assembly to the Ironworker frame.

2. Remove blade bolts located behind the guard. Remove the station-

ary blades.

3. With blades removed, clean blade pocket of any dirt or debris.

4. Your shear blades have multiple cutting surfaces that can be used

prior to full replacement of the part. Rotate the stationary blades to

new cutting surface and reinstall in blade pocket.

5. Tighten the stationary blades back into the blade pocket.

6. Replace and secure the material hold-down and guarding to the

Ironworker frame.

Remove and replace moving blade:

1. Remove the angle shear drop-off guard from the rear of the Iron-

worker frame.
