Cuisinart CSB-77 - Manual (Page 10)

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 holding 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 Smart Stick ® 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.
4a. Be sure that the 3 ridges at the top of the blade assembly
line up with the 3-arm propeller gear in the underside of the
chopper/grinder cover, and that the cover is seated all around the
top of the prep bowl.
4b. To properly seat the cover, you must line up the three molded
pins from the cover with the 3 slots at the top of the prep bowl.
Rotate cover counterclockwise to secure it to the prep bowl.
Rotate the cover until the pins are in the far left position in
the slots.
