BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to
a razor edge, but leave a 1/16” blunt edge. Do not sharpen back side of blade.
Avoid personal injury. Always block the cutter up to prevent if from falling when the blades
and / or carrier are being serviced.
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR
WELD ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE
BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES.
