3. Components
Your Oster Classic Blender OBL245X consists of the following main components:
- Motor Base: Contains the powerful 600W motor and control dial. Features the durable All Metal Drive system.
- Glass Jar (1.25 L): A durable, odor-resistant, and scratch-resistant borosilicate glass jar.
- Blade Assembly: Stainless steel blades designed for efficient blending and ice crushing.
- Sealing Gasket: Ensures a leak-proof seal between the blade assembly and the jar.
- Jar Base: Secures the blade assembly and gasket to the bottom of the glass jar.
- Lid: Fits securely on top of the glass jar to prevent spills during operation.


4. Setup
Before using your blender for the first time, wash the jar, lid, and blade assembly in warm, soapy water. Rinse thoroughly and dry.
Assembly Steps:
- Assemble the Blade: Place the sealing gasket onto the blade assembly. Ensure it is seated correctly.
- Attach to Jar: Insert the blade assembly with the gasket into the opening at the bottom of the glass jar.
- Secure Jar Base: Screw the jar base onto the bottom of the glass jar, turning clockwise until it is tightly secured.
- Place on Motor Base: Position the assembled jar onto the motor base. Ensure it is seated firmly and correctly aligned.

5. Operating Instructions
Follow these steps for safe and effective blending:
- Prepare Ingredients: Cut solid ingredients into small pieces (approximately 2-3 cm).
- Load the Jar: Always add liquids first, then soft ingredients, followed by hard ingredients, and finally ice. Do not exceed the 1.25 L maximum fill line on the jar.
- Secure the Lid: Place the lid firmly on the glass jar. Ensure the filler cap is also in place.
- Plug In: Plug the blender into a 220V electrical outlet.
- Select Speed: Turn the control dial to your desired speed setting (1, 2, or 3). For quick bursts, you can use the pulse function by briefly turning the dial to a speed and then releasing.
- Blend: Allow the blender to run until the desired consistency is achieved.
- Stop: Turn the control dial to the "OFF" position when blending is complete.
- Unplug: Always unplug the blender from the outlet after use and before disassembling or cleaning.
Tips for Best Results:
- For thick mixtures, use a lower speed initially and gradually increase.
- When crushing ice, use short bursts on a higher speed.
- Do not blend continuously for more than 3 minutes. Allow the motor to rest between cycles.
- Never operate the blender empty.
