Your Ironworker may include a Rod Shear or Multi Shear assem-
bly as an optional tool. When maintained within tolerance, these
shears will provide a distortion and burr free cut to mild steel rod,
square, bar and small angle stock. Both Edwards Rod Shear or
Multi Shear assemblies are“bump-die” tools consisting of a hous-
ing which holds a stationary blade, a moving blade, return springs
and a push block. The moving “center” of the Ironworker, pushes
on the top moving blade via the push block to shear the mate-
rial. Blades within the Rod Shear and Multi Shear assemblies are
wearing parts and will require replacement over time. Observe the
following procedures when maintaining or replacing components
of the Rod or Multi Shear assemblies.
Turn off power to machine by depressing the red stop/off
button and lockout upstream power at the main electrical
panel.
Remove and replace moving blade:
1. Remove Rod Shear or Multi Shear assembly from tooling station by
removing the four 1/2” bolts, nuts and washers.
2. Remove the two 1/2” allen head screws that secure the push block
to the moving blade.Remove damaged blade from base housing.
Reserve the push block and return springs for installation of new
blade.
3. Clean the pushblock and return springs of any dirt or debris.
4. Install new moving top blade to pushblock with allen head screws
provided. Re-install return springs. and return moving blade to base
housing.
Remove and replace stationary blade:
1 The Rod Shear or Multi Shear assembly includes one or two blades
secured within the base housing. Remove the six 1/2” socket head
cap screws and spacers that secure the guard and blade into the
base housing.
2. Clean the blade pocket of any dirt or debris.
3. Install new cutting blades into the blade pocket. Re-install the
guarding and the six 1/2” socket head cap screws and spacers
provided and tighten.
5. Check for moving and stationary blade alignment by powering up
the machine and slowly jog the center down. The blades will bypass
each other. The push block should not come in contact with the
base housing.
6. Periodically lubricate the Rod Shear or Multi Shear assembly as
indicated on the tooling.
