Using the product

1. How to fit/remove blades (big jar, medium jar, blender jar) 
   Hold the coupler on the underside of the jar and with the spatula, tighten by rotating in an anti-clockwise direction to fit and clockwise to remove until the blade is securely locked/removed.

   

   Note: If the coupler and/or some other parts are removed during removing the blade.

2. How to fit jar to main unit
   Carefully insert the jar on top of the main unit. Ensure that the lock of the jar fits into the slot of the main unit. Rotate the jar clockwise until it locks and use the handle to lock.

   

3. How to fit/remove active flow breaker
   Your Bosch TrueMixx Style Mixer Grinder has an active flow breaker which improves the quality of your wet grinding applications. To fit the active flow breaker, insert the active flow breaker in the groove on the inside surface of the big jar and slide it in until it fits properly. To remove it, gently press in the opposite direction till it disengages. Slide it out thereafter.

   

4. How to use MaxxJuice extractor (only for MGM8842.IN)
   For mixing smoothies use the blender jar with the blender jar blade. Put the MaxxJuice extractor in the blender jar as shown and press it gently down.

   

Safety systems

The Bosch TrueMixx Pro Mixer Grinder  is fitted with an overload protector (OFF) mechanism to prevent the motor burning out due to overloading. In case of excess loading with ingredients in the jar, very thick paste or low voltage conditions, your Bosch mixer grinder automatically switches off and the red knob on the bottom of the mixer grinder will spring out. 

If this happens, switch off your mixer grinder and remove the excess ingredients. Add sufficient water if dealing with thick paste and wait for 2-3 minutes. Press the red reset button and start the mixer grinder again. 

Operating your mixer grinder

Before using for the first time / using after a long time

• Before using the mixer grinder for the first time or using it after a long time, thoroughly clean all the parts that come into contact with food ingredients.
• Rotate the motor shaft by hand via the motor coupler, on top of the main unit. The motor shaft should rotate freely.
• Check that the speed selector is in the OFF position.
• Place the main unit on a smooth, stable and clean surface.

Caution! Never place plastic, paper or cloth under the mixer grinder as it may block the ventilation holes.

1. Connect the main plug to the wall socket. Your Mixer Grinder has a dummy 3rd pin on the plug to ensure stable fixing onto the plug point. Switch on the main supply and turn the speed selector knob to the required position and speed. After operation, turn the speed selector knob to the OFF position and check. Repeat until the desired results are obtained.
2. You may observe some minor oil spillage in the Jars and Jar sockets during first two to three operations. This is normal. Thoroughly clean the minor oil spillages with water and wipe dry with soft cloth.

Preparation of ingredients
Important! 

• Cool down any hot ingredients before putting in the jar.
• Cut large ingredients into small pieces approx. 2 cm in size before mixing/grinding.

Regular use and operation

• For blending/liquidising/puréeing use ‘Pulse’ on the speed selector knob. This will activate Pulse until you release the button. Use position 1-3 for continuous operation.
  1 = Lowest operating speed
  3 = Highest operating speed
  Hold down the jar lid gently while your mixer grinder is in operation.
• After switching off the mixer grinder, wait until the blade stops rotating completely and only then remove the lid or insert the spatula.
• Before removing the jar from the main unit, ensure that the power supply is disconnected.
• Avoid using your hand to fill or clean jars. It is safer and more hygienic to use the spatula.
• Avoid storing food in the jar.
