- Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or has been dropped or damaged in any manner.

Parts Identification
Familiarize yourself with the components of your Tristar BL-4431 Blender:

Setup and Assembly
Follow these steps to assemble your blender before first use:
- Before first use, wash all removable parts (glass jar, blade assembly, lid) in warm soapy water. Rinse thoroughly and dry.
- Place the sealing ring securely onto the blade assembly. Ensure it is seated correctly to prevent leaks.
- Screw the blade assembly onto the bottom of the glass jar. Tighten it firmly to ensure a leak-proof seal.
- Place the assembled glass jar (with blade) onto the motor base. Ensure it is correctly aligned and locked into position. The blender will not operate if the jar is not properly seated.
- Plug the power cord into a suitable electrical outlet.

Operating Your Blender
Follow these instructions for safe and effective blending:
- Prepare Ingredients: Cut fruits and vegetables into small pieces (approximately 2-3 cm) to ensure smooth blending and prevent strain on the motor.
- Add Ingredients: Place your prepared ingredients into the glass jar. Do not exceed the maximum fill line (0.45 L). For best results, add liquids first, then soft ingredients, and finally harder ingredients or ice.
- Secure Lid: Securely place the lid on the glass jar.
- Position Jar: Ensure the glass jar is correctly seated on the motor base.
- Select Speed: Select the desired speed setting using the control buttons on the motor base. The blender offers two speed settings.
- Blend: Press and hold the button for continuous blending. Release the button to stop.
- Add During Blending: For adding ingredients during blending, use the filling opening in the lid.
- Finish: Once blending is complete, release the button, unplug the appliance, and carefully remove the glass jar from the motor base.
Tips for Best Results
- Do not operate the blender continuously for more than 1 minute. Allow it to cool down for a few minutes before resuming.
- For thicker mixtures, use the pulse function (briefly press and release the button) or add more liquid.
- Never blend hot liquids, as pressure buildup can cause the lid to open and hot contents to spray out.
Cleaning and Maintenance
Regular cleaning ensures optimal performance and extends the life of your blender.
- Always unplug the blender before cleaning.
- Disassemble the blender: Remove the lid, glass jar, and unscrew the blade assembly from the jar.
- Wash the glass jar, blade assembly, and lid in warm, soapy water. Use a brush for thorough cleaning of the blades.
- Rinse all parts thoroughly and dry immediately.
- The motor base can be wiped clean with a damp cloth. Never immerse the motor base in water or any other liquid.
- For quick cleaning, fill the glass jar with warm water and a drop of dish soap. Place it on the motor base, secure the lid, and run the blender for a few seconds. Rinse thoroughly.
