Adjusting Shear
Blade Gap
The gap between the upper and lower shear
blades (as they pass each other) must remain
even along the length of blades to produce clean
cuts. Initially, this adjustment has been made at
the factory. However, over time and with normal
wear, you may need to re-adjust this gap.
If the blade gap is too wide, the workpiece will
not cut correctly and show signs of bending, rip-
ping, or tearing. If the blade gap is too narrow, it
will be difficult to lower the upper blade past the
lower blade and the cutting edges may become
damaged.
The shear blades on are

Keep
least 6" away from blades
when cutting to test blade
gap. Never reach between
blades unless they are
blocked from closing.
Checking Shear Blade Gap
Use a piece of paper to perform a shear cut test,
making cuts along the full length of the shear
blades. All cuts should be sharp without bending
or tearing the paper.
•
If cut is clean at one end and not the other,
perform the Adjusting Shear Table proce-
dure.
•
If paper cuts cleanly on the ends but not in
the center, or it cuts cleanly in the center
but not on the ends, blade bow needs to be
adjusted (refer to Adjusting Blade Bow on
Page 31).

To adjust shear table:
1.
Loosen cap screws on both ends of shear
table that secure it to machine (see Figure 48).

2.
Evenly rotate table adjustment screws to
adjust position of shear table until blade gap
is even, then retighten cap screws to secure
table.
Note: Rotating table adjustment screws
clockwise moves table toward the upper
shear blade.
3.
Perform shear test cut (refer to Checking
Blade Gap). If necessary, repeat Steps 1–3
until you are satisfied with shear cut test.
