Metal Panel Shears

Maintenance Protocol

Apply light oil, such as WD40, to top and bottom blade cutting surfaces periodically prior to operation. Periodically check the grease on the heel pad of the shear. Clean off dirt as necessary and grease with any heavy-duty grease. To grease the entire heel pad of the shear or for disassembly of shear, for any reason, note the instructions under "Reassembly of Shear".

Blade Replacement

Tools Required:

3/16" Allen wrench
1/2" socket & drive

How to replace the blade:

Open shear fully
Loosen and remove fasteners on top and bottom blades and pull blades off
Place new blades on top and bottom and tighten fasteners
Once new blades are attached, follow Blade Realignment Procedure if necessary.

Reassembly of Shear:

Note: Only needed for complete disassembly of shear

Set bottom frame back on top frame and insert pivot bolt from bottom.

Install washers (1 flat, 2 springs, 1 flat) and locknut. Note the orientation of the spring washers as depicted on the label near the pivot block on the bottom frame of the shear.

Reattach springs to spring mount holes.   

Lift shear to upright position making sure both spring hooks remain engaged.    

Tighten locknut until spring washers nearly flatten when shear is closed. They should not touch.

Important Note: Spring Washers should be fully compressed when shear is roughly ¾ of the way closed. You know you have it adjusted correctly when you hear the consistent swoosh of metal on metal.

Blade Alignment

After changing blades, it may be necessary to align the top blade with the bottom blade in order to achieve the best cut possible. This is done using the adjusting screws that move the pivot bolt to the front or rear. Simply loosen the lock nuts and move the pivot bolt either direction. Be sure to retighten the lock nuts when adjustment is complete. You want to make sure that the profile on the top and bottom blades match on the first rib.
