Operating Instructions
Basic Blending
- Prepare Ingredients: Cut ingredients into appropriate sizes for blending. Do not overfill the 4-liter jug.
- Load Jug: Place ingredients into the stainless steel jug. For best results, add liquids first, then soft ingredients, and finally harder ingredients or ice.
- Secure Lid: Place the lid firmly onto the jug. Ensure the lid is properly sealed to prevent spills during operation.
- Select Speed: Turn the speed control knob on the front panel to the desired setting. The blender offers variable speed control.
- Start Blending: Press the ON button to begin blending.
- Pulse Function: For short bursts of power or to chop ingredients, press and hold the "PULSE" button. Release to stop.
- Stop Blending: Press the OFF button or turn the speed control knob to the '0' position.
- Unload: Wait for the blades to completely stop before removing the lid and pouring out the contents.
Tips for Optimal Performance
- Do not blend extremely hot liquids, as pressure buildup can cause the lid to dislodge.
- For thick mixtures, use the pulse function to help move ingredients around.
- Avoid running the blender empty.
- The jug can be oriented into any position for convenience.
Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Santos blender.
- Unplug: Always unplug the blender from the power outlet before cleaning.
- Jug Cleaning: For quick cleaning, fill the jug halfway with warm water and a drop of dish soap. Secure the lid and run the blender on low speed for 30 seconds. Rinse thoroughly. For deeper cleaning, disassemble the jug components if possible and wash by hand.
- Motor Base: Wipe the motor base with a damp cloth. Do not immerse the motor base in water.
- Blades: Exercise extreme caution when cleaning the blades as they are very sharp. Use a brush if necessary.
- Storage: Store the blender in a clean, dry place when not in use.
