MSD SABER SERIES SHEARS
WELD-IN TIP CUTTING BLADE ROTATION PROCEDURE
Proper rotation and adjustment of the cutting blades is very important for the best shear performance and
longer shear life. It is recommended that the blades be rotated after every 80 hours of use.
SECOND AND FOURTH BLADE EDGE ROTATION
1. Remove all blades.
2. Swap the blade positions.
3. Replace Weld-In Tip as required.

FIRST AND THIRD BLADE EDGE ROTATION
1. Remove each blade.
2. Turn end for end.
3. Reinstall in same seat.
4. Replace Weld-In Tip as required.
Never operate a shear when the blade edges have round 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.
1. Keep track of all parts and their positions as you remove them. This will be important when reinstalling.
2. Once the blades are removed, use a small grinder to clean up the edges and blade seats, remove sharp
burrs and smooth out deformations.
3. See Figure 5-16 . 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.
4. See Figure 5-17 . For the second blade edge rotation (when edges have rounded to a 1/4” radius), swap
the blade positions (primary to secondary and secondary to primary).
5 . 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 the SOM. Always use the same
size and class of bolts. Refer to your Parts Catalog to order replacement bolts from your authorized Stanley
LaBounty dealer.
6. 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.
