General safety advice / Use
Turn the rotary switch
until you hear a grinding noise.
NOTE: The rotary switch
tion of the sharpening stone in the sharpening
head housing and therefore the pressure of the
sharpening stone against the drill. The further
you turn the rotary switch
rection, the greater the pressure. Ensure that
you do not turn the sharpening stone too far up.
Otherwise the sharpening stone could strike
the housing.
Turn the drill under slight pressure loosely and
quickly to and fro between the left and right
stops about 10 times (with small drills about
5 times).
Pull the drill out, turn it through 180° (horizontally)
and insert it again until it meets the sharpening
stone.
If necessary repeat whole process until both
cutting edges of the drill are sharp. Control the
grinding operation so that the angle between
the main and transverse cutting edges for a
standard drill is 130°. Both cutting edges (b)
must have the same angle to the drill axis (a)
and be the same length so that the drill runs
concentrically (see following figures).
Press the ON / OFF switch
