26 | MSD Legend Series Operation & Maintenance Manual
BLADE MAINTENANCE
Overview
The MSD Legend shear has eight blades that must be maintained regularly to ensure the attachment has a long
and dependable service life. Blade maintenance requires that all blade gaps and hardware torques are checked and
adjusted if necessary every 8 hours. Every 80 hours, the slide screw must be adjusted and blade positions must be
rotated. This will ensure uniform wearing of the blades and will prevent material jams.

Before removing blades, position the shear on the ground, so that the blades being removed are close to the
ground. When removing upper blades or piercing tip, curl the shear, as shown in Figure 20.
Note: For non-rotating shears, knuckle the shear under the boom, as shown in Figure 20, to replace the upper jaw
blades and piecing tip. extend the shear completely out and set it on the ground to service the lower blades.
