Note these important features of the blade ring. The blade
ring can be placed over the plastic blade sheath in two dif-
ferent ways:
If you hold it as in figure A, you will see the word "Sharp"
on the blade. Assemble the blade this side up to use the
sharp edge. (See the section on processing food, page 9,
for information about when to use the sharp edge.)
If you hold it as in figure B, you will see no writing on the
blade. Assemble the blade this side up to use the blunt
edge.
See the section on processing food, page 9, for information
about when to use the blunt edge.
There are notches (C) on opposite sides of the interior of the
hub. These fit over ridges on the sides of the plastic blade
sheath.

Pick up the blade ring by its hub holding ribs (grips) and
line up the notches in the interior of the blade ring hub with
the ridges on the sides of the plastic blade sheath. Let the
blade ring slide down to the bottom of the plastic blade

sheath. The lower blade should
almost touch the bottom of the
prep bowl.
Lift the prep bowl, holding it
firmly from the bottom. Pick up
the blade ring by its hub hold-
ing ribs (grips) and turn it very
slightly clockwise. This locks it
in place on the plastic blade
sheath and prevents it from
sliding up during processing.
3. Connect the hand blender
motor body to the top of the
chopper/grinder attachment
cover. Align the spline in the
chopper/grinder cover's drive
shaft with the ribbed opening
on the underside of the motor
body. When aligned properly,
slide the two pieces together
until they mate. You will feel
and hear a slight click. It may
be helpful to press the rubber
release button when sliding
these pieces together.
4. With the hand blender in place,
locate the chopper/grinder
cover and place it on top of the
prep bowl.
a. Be sure that the 3 ridges at
the top of the blade assem-
bly line up with the 3-arm
propeller gear in the under-
side of the chopper/grinder
cover, and that the cover is
seated all around the top of
the prep bowl.
b. To properly seat the cover,
you must line up the three
molded pins from the cover
with the 3 slots at the top of
