BLADE CLEARANCE
The blade clearance on the LM1014 was set at the factory to .003 in. on the ends of the blades with a .002
gap in the center of the machine. At this setting, your shear should provide satisfactory results over a
broad range of materials and thickness. However, when shearing lighter gauge materials a tighter blade
gap may be desired. Also, upon turning the blades to a new edge or after re-sharpening the blades, the
blade clearance must be reset.
CAUTION!
Checking the blade gap will require removing the wire finger guard (80). Do not operate the
shear without the guard in place. To check the blade clearance, set the machine to the jog mode and jog
the cutter head down so that the blades just overlap at the point at which the inspection is to take place.
WARNING! Disconnect power to the machine prior to making the measurement. Use a feeler gauge to
make the measurement.
The blade clearance adjustment is made in the following manner:
1 . Loosen the two table locking bolts (49) located near the mid-section of each side panel and then
retighten the bolts hand tight.
2 . Loosen the four table bolts (43), again reasserting only a slight amount of pressure back to each
one.
3. The table positioning screws (20) located at both ends of the table are the means used to achieve
the proper blade clearance. The forward screw pushes the table and bottom blade toward the
cutter head. Likewise, the rear screw adjusts the blade back, thus increasing the clearance. To
set the clearance, place a feeler gauge of the same thickness as the desired clearance between
the two blades. Adjust the forward screw outward until the feeler gauge is locked between the
blades and cannot be removed. Then adjust the rear screw in the opposite direction until the
gauge stock is freed. The opposing actions of the screws serve to attain a tight, positive setting.
4 . After setting the clearance on both ends of the machine, retighten the four table bolts and the two
locking bolts.
5 . The blade clearance in the center of the machine controlled by adjusting the center truss located at
the rear of the cutter head. The blade clearance in the center of the shear should be set at least
.001 closer than the dimension chosen for the ends of the blade.
6 . Reposition all protective guards and covers.
