Turn off power to machine by depressing the red stop / 

off button and lockout upstream power at the main elec-

trical panel.

Observe the following procedure when maintaining the Iron-

worker Coper Notcher station.

Remove and replace moving blade: 

1.   Remove or swing the Coper Notcher guard assembly up 

and away from the Coper Notcher table. 

2.  Remove the two 1/2" socket head cap screws that se-

cure the existing top Coper Notcher blade to the moving 

center.

3.  Clean the keyway in the moving center of any dirt or de-

bris.

4.   Install the top Coper Notcher blade with the keyway up 

and the “foot” of the blade facing the center of the ma-

chine. Secure the top blade using two 1/2" socket head 

cap screws. Tighten bolts.

Remove and replace stationary blades: 

1   Loosen the set screws (if provided) located at the sides 

of the Coper Notcher table.

2.  The Coper Notcher table includes three blades secured 

within the table housing. Remove the four 1/2" bolts and 

washers that secure Coper Notcher table to the base 

table.

3.  Carefully remove the Coper Notcher table assembly to 

a secure workbench. The top table that holds the blade 

set is secured by eight 3/8" socket head cap screws - 

four from the top working surface, four from the underside 

of the Coper Notcher assembly. Remove all eight cap 

screws to separate the blade housing from the Coper 

Notcher assembly. Remove the top table from the as-

sembly.

4.   Remove the six 3/8" socket head cap screws that secure 

the blades into the base table housing.

5.  Clean the blade pockets of any dirt or debris.

6.  The bottom shear blades have multiple cutting surfaces. 

Either rotate/flip the existing blade set to the new cutting 

surfaces or install new cutting blades into the blade pock-

ets. Re-install the six 1/2" socket head cap screws and 

tighten. The blades should be parallel to each other at the 

top surface of the working table. 

7.  Re-install the eight cap screws that secure the top table 

housing to the bottom table housing.

8.  Re-install the Coper Notcher table with the open “U” fac-

ing the center of the machine. The guide foot of the top 

Coper Notcher blade should be centered within the base 

table blades.

9.   Loosely secure the Coper Notcher table from the under-

side of the base with four 1/2" bolts and washers (pro-

vided). 

10. Check for top and bottom blade alignment by powering 

up the machine and slowly inching down the top blade to 

meet the bottom blades with the foot pedal. Power the 

machine off. 

11. Using a feeler gauge, adjust the clearance between the 

perimeter of the top and bottom blades to allow for .010" 

clearance on all three sides.

12. In the event that the top and bottom blades are not 

aligned, simply loosen the bolts under the table allowing 

the table to be moved to center the top blade within the 

bottom blades. When aligned, tighten the table bolts to 

secure the table.

13. Adjust the set screws (if provided) at the sides of the 

Coper Notcher table to engage the base Coper Notcher 

table to the base table. Lock the four 3/8" nuts in place to 

secure the set screws in place. These added fixtures are 

to provide additional support to the base table during the 

notching operation.

14.  Swing the Coper Notcher guard back in place.
