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, ripping, 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,.do.these.steps:
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 on only 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 center of
blades, or it cuts cleanly in center but not ends,
blade bow needs to be adjusted (refer to Adjusting
Blade Bow on Page 30
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 29
).
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 adjustment bolts
to move table and lower blade until lower blade
makes light contact with feeler gauge against upper
blade.
