Blade Sharpening

IMPORTANT: Replace any blade that is worn,
wraped, cracked or otherwise damaged in any
way.
IMPORTANT: Sharpen every tooth evenly so
the blade rotates smoothly. If you sharpen a
blade with a grinder, do not overheat the blade,
and do not quench a hot blade in water to cool it.
Never leave a sharp radius or groove when
grinding or filing.
