No lubrication is needed or required for any moving parts,
motor, bearings, or sharpening surfaces. There is no need
for water on abrasives. The exterior of the sharpener may
be cleaned by carefully wiping with damp cloth. Do not use
detergents or abrasives.
Metal dust will slowly accumulate below the Coarse and
Fine grinding wheels. A removable drawer can be found
underneath the grinding wheels in the rear of the unit. On
occasion, remove drawer and wipe with a damp cloth or
paper towel. This will remove all of the metal shavings.
Replace drawer.
