Setup
Before initial use, ensure all components are clean. Wash the Boroclass glass jar, lid, and filler cap in warm, soapy water or in a dishwasher. The blade assembly can also be disassembled for thorough cleaning.

Image Description: A stainless steel Oster Classic Series Heritage Blender with a 6-cup Boroclass glass jar filled with various fruits (pineapple, blueberries, raspberries) ready for blending. The blender base is brushed stainless steel with a simple toggle switch for operation.
- Place the blender base on a stable, flat surface.
- Ensure the blade assembly is securely attached to the bottom of the 6-cup Boroclass glass jar.
- Carefully place the assembled jar onto the blender base, aligning it properly.
- Place the lid securely on the glass jar. The 2-ounce filler cap should be inserted into the opening of the lid.
- Plug the power cord into a standard electrical outlet.
Operating Instructions
The Oster Classic Series Heritage Blender features a simple 2-speed toggle control for ease of use.
- Adding Ingredients: Add your desired ingredients to the Boroclass glass jar. Ensure the liquid ingredients are added first to facilitate smoother blending. The 2-ounce filler cap allows for convenient addition of ingredients while blending.
- Speed Selection: Use the toggle switch on the blender base to select your desired speed.
- HIGH: For powerful blending, ideal for crushing ice, frozen fruits, and tougher ingredients.
- LOW: For lighter blending tasks, such as mixing sauces or pureeing soft foods.
- PULSE: For short bursts of power, useful for chopping or controlling texture. Activate by momentarily moving the toggle switch to the pulse position and releasing.
- Blending: Begin blending by selecting the appropriate speed. The powerful 1000-watt motor and Crush Pro 4 Blade (stainless steel, 4-point design) will pulverize and chop ingredients with precision.
- Stopping: To stop blending, return the toggle switch to the 'OFF' (center) position.
Maintenance and Cleaning
Proper maintenance ensures the longevity and hygiene of your blender.
- Unplug Before Cleaning: Always unplug the blender from the electrical outlet before cleaning.
- Glass Jar and Lid: The 6-Cup Boroclass Glass Jar and its lid are dishwasher safe for easy cleanup. They can also be washed by hand with warm, soapy water.
- Blade Assembly: The Crush Pro 4 Blade assembly can be detached from the jar for thorough cleaning. Exercise caution as the blades are sharp. Wash with warm, soapy water and rinse thoroughly.
- Blender Base: Wipe the blender base with a damp cloth. Do not immerse the base in water or any other liquid.
- Storage: Store the blender in a dry place. Ensure all parts are completely dry before storing.
Troubleshooting
If your blender is not operating as expected, please check the following common issues:
- Blender Does Not Turn On: Ensure the power cord is securely plugged into a working electrical outlet. Check if the toggle switch is in the 'ON' position.
- Ingredients Not Blending Properly: Ensure the jar is properly seated on the base. Add more liquid if the mixture is too thick. Cut larger ingredients into smaller pieces.
- Loud Noise/Vibration: This may indicate that the jar is not properly aligned on the base or that the ingredients are too dense. Stop the blender, adjust the jar, or add more liquid.
- Leakage from Jar: Ensure the blade assembly is tightly secured to the bottom of the jar and that the gasket is correctly in place. Also, check that the lid is properly sealed.
