Like most cutting instruments, a diamond blade performs best when it is dressed. Over time and
use, diamonds on the outer edge will become smoothed or “glazed” over. This will reduce grinding
efficiency and may cause the blade to “wander” or bend giving the illusion of an alignment problem.
When this occurs, the blade will need to be dressed. The diamond blade can be dressed using the
MK Dressing Stick (part number 152792) and by following the steps below.
BLADE DRESSING
Skip Steps C and D if cutting dry. NOTE:
