► NOTE: THE BOLSTER MUST BE REMOVED FIRST, TO ALLOWROOM FOR THIS TOOL.
For clarity, the tool is shown with the guard removed. DO NOT operate the tool with the guard removed.
7.5A CHANNEL SHEAR INSTALLATION
1. Place the selector switch in the PUNCH position and allow the ram to retract. Turn the power to
the machine off.
2. Before installing the tool on the machine, remove the top blade (A) and install the spring guide
rods (B) and springs. (REFER TO THE INSERT IN FIGURE 25.) Install the spring guide rods
with the head down in the tool.s side plate. Then, install the springs on the rods.
3. Replace the top blade (A).
4. There is an extra set of backup set screws for the stationary vertical blades. These longer screws
must be used when shearing smaller channel.
5. Because of clearances, it is necessary to mount the finger clamps (C) to the punch bed and start
the bolts before installing the tool.
6. After the finger clamps are in place, slide the tool onto the punch bed under the finger clamps.
7. Align the tool so that the punch ram will come down directly over, and be evenly distributed on,
the pressure block of the tool. If the ram pressure is not evenly distributed on the pressure block,
the side load may cause damage to the tool.
8. After a visual inspection has been made on the lineup, tighten the finger clamp bolts.
9. Place the selector switch in the START position and the run/jog switch in the JOG position. Power
the machine and place the selector switch in the PUNCH position.
10. Jog the punch ram down to within 1/8 of an inch (3mm) of the pressure block on the tool and set
the upper stroke control. Set the lower stroke control as low as possible, without bottoming out the
ram on any part of the tool.
11. Place the run/jog switch in the RUN position.
