MSD SABER SERIES SHEARS
CUTTING PERFORMANCE TROUBLESHOOTING GUIDE
IMPORTANT NOTE: If the shear is jammed with material caught in the jaws and will not open, lubricate the
blades with penetrating oil and attempt to cycle the shear open. If the jam persists, remove the lower blades
and guide blades fasteners and open the shear. This will allow the blades to come out of their seats thus
freeing the jam. Upon jam removal, perform the proper maintenance on the shear as detailed in this manual.
