Adjusting Blade Gap
The gap between the upper and lower blades (as
they pass each other) must remain even along
the length of the 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 adjust the blade 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,
the upper blade will bind when lowering past the
lower blade and the cutting edges may become
damaged.

To adjust blade gap:
1.
Make cuts on piece of paper along full length
of shear blades.
— If paper cuts cleanly on full length of shear
blades, blade gap requires no adjustment.
— If paper does not cut cleanly only on one
end of shear, lower blade needs to be
adjusted on that end. Proceed to Step 2.
— If paper does not cut cleanly along the
entire length of blades, both ends of lower
blade need to be adjusted. Proceed to
Step 2.
— If paper cuts cleanly on ends but not cen-
ter of blades, or it cuts cleanly in center but
not ends, blade bow needs to be adjusted
(refer to Adjusting Blade Bow on Page
27 for detailed instructions).

2.
Loosen (2) table bolts, (2) table adjustment
bolts, and (2) jam nuts on side of shear that
needs adjustment (see Figure 36).

3.
Use foot pedal to lower and hold upper blade
in lowest position.
4.
Insert feeler gauge between blades on side
that needs adjustment, then turn table adjust-
ment bolts to move table and lower blade
until lower blade makes light contact with
feeler gauge against upper blade.
5.
Tighten (2) jam nuts and (2) table bolts to
secure blade gap adjustment.
6.
Repeat Step 1 to check adjustment.
— If paper still does not cut cleanly, but
blade gap adjustment is correct, blade(s)
may need to be sharpened (refer to
Sharpening/Replacing Blade on Page
25 for detailed instructions).
