MAINTENANCE
Keep the Sharpener clean and free of 1.
dust, metal debris and dirt.
Check the Grinding Wheel before each
2.
use to make sure it isn’t damaged. Do
not use a grinding wheel if it is chipped,
cracked, or worn. You can check if
the wheel has cracks not visible to the
human eye by hanging it up by the
central hole and tapping it with a non
metal object (ie: screwdriver handle). If
it is in good condition it will produce a
metallic sound. A dull sound indicates a
crack or break.
Replace the Grinding Wheel when it
3.
grinds down to a diameter of 3 inches.
