Cuisinart makes several versions of its Smart Stick hand blender. With these hand blenders, there are two types of blades: those mounted on the blending shaft and those that work with the chopper/grinder attachment. You do not need to remove the blades themselves from the shaft for cleaning and maintenance. It also also possible to repair the blades on a Cuisinart Smart Stick by removing the entire part containing the blades.
Important Safety Considerations
Before undertaking a repair of your hand blender, it's important that you consult the manual and be familiar with how it works. You should never attempt to repair the appliance while it is turned on or plugged in. In addition, be sure that the blender is not wet or slippery in any way. You don't want it to slide while you are working, since the blades could then cut you. If you happen to have protective gloves you can wear during the repair process, that is ideal.
Video of the Day
Do not undertake this project when small children or pets are around, as they may bump you or otherwise inadvertantly interfere with the repair process. Be sure you are working in a well-lit area to avoid injuries or damage to the surfaces you are working on. The blade could cut or mark a table or countertop, depending on their material, if it were to slide or fall because you couldn't see what you were doing.
Cuisinart Smart Stick Blade Repair
If your Cuisinart Smart Stick Blade won't turn or your Cuisinart hand blender won't turn on, it is very possible to repair the appliance, rather than replacing it.
To repair the blades, remove and replace the part containing the blades, rather than working directly with the blades. Use only authorized replacement parts on your Smart Stick blender. Parts are available through the Cuisinart website. If you are unsure which parts you need, contact the manufacturer for guidance.
To begin, turn the appliance off to ensure the motor is completely stopped. Detach the charger handle from the motor body. Unplug the appliance before you begin any work with the blades of the device, warns the Cuisinart instruction book for the Cordless Rechargeable hand blender and Smart Stick hand blender.
Cuisinart Smart Stick Disassembly
Next, grasp the detachable blade shaft near the motor body, away from the blade end. Press the release button. Pull the detachable blade shaft away from the motor body to remove the main blades from the hand blender.
Remove the chopper/grinder attachment's reversible blade. Release and remove the motor body from the attachment cover. While holding the prep bowl by its bottom, grasp the central hub's holding ribs/grips using the fingers of your opposite hand.
Keeping your fingers away from the blades, turn the blade ring counterclockwise. Disconnect the blade ring from the plastic blade sheath by lifting the blade off the sheath. Work the blade ring over the notches on the blade sheath as necessary to free the blade if you need to further disassemble the unit for shipping or repair.
