MSD SABER SERIES SHEARS
CUTTING BLADE ROTATION
continued
The startup kit for every new shear contains two
extra blades. Keep these blades for the second time
you rotate edges and replace blades. For the fi rst
rotation, you’ll only need the original four blades; the
second time, you’ll be using new blades.
1. See Figure 5-9. Turn each original blade end-for-
end and return each one to its original seat. When
done, you have completed the procedure for the
fi rst blade edge rotation.
2. See Figure 5-10. For the second blade edge
rotation (when edges have rounded to a 1/4” radius),
remove and discard the lower blades. Next, remove
the two upper blades, swap end-for-end, and install
in the lower seats. Now install two new blades in
the open upper seats.
3. Whenever you rotate or replace cutting blade
edges, make sure all blades are seated properly and
use a new set of blade bolts and torque according
to the Dry Bolt Torque Chart in this section. Always
use the same size and class of bolts. Refer to your
Parts Catalog to order replacement bolts from your
authorized Stanley LaBounty dealer.
4. Cross blade and guide blade maintenance should
be performed when lower blades are being rotated.
Keep track of all parts and their positions as you
remove them to make reinstallation easier.
Never operate a shear when the blade edges have
rounded to a 1/4” (6 mm) radius or more. Operating
the shear with badly worn blades greatly decreases
shear performance and can eventually cause
structural and hydraulic damage to the shear.

FIRST AND THIRD BLADE EDGE ROTATION
1. Remove each blade.
2. Turn end for end.
3. Reinstall in same seat.
4. Replace Saber Tip as required.
SECOND BLADE EDGE ROTATION
1. Discard lower blades.
2. Rotate upper blades to lower blade seats.
3. Install two new blades in upper seats.

NEW BLADES
If you follow these directions correctly, each
time you order a new set of four blades you’ll be
setting aside two blades for a second rotation—
at every second blade fl ip, two new blades
will be inserted in the top blade seats. NEVER
ROTATE USED LOWER BLADES INTO UPPER
BLADE SEATS.
