Sharpening Guide

Making sure that the Chuck
rests firmly against the Cam
Guide, turn the Chuck one
half-turn to the right—to the
other Sharpening Guide.

Turn from Guide to Guide in a
smooth and even motion until
the bit is sharp. To sharpen
both sides of the bit evenly,
always use an even number
of half-turns. The number of
half-turns needed to sharpen
the bit depends on its size.

Turn the Chuck an even number of half-turns with light
inward pressure:

—use 2 to 4 half-turns, 

—use 4 to 6 half-turns, 

—use 16 to 20 half-turns.

Use just enough pressure to keep the Cam against

the Cam Guide. Let the machine do the sharpening.
