Clean the dust shield on the chuck with a dry, clean

is replaced if the sealing lip is found to be damaged.
Push the tip of a screwdriver under the edge of the
dust shield and prise it out toward the front. Clean
the area of the chuck in contact with dust shield and
then fit a new dust shield. Press it in firmly until it
