Frequently Asked Questions - GJ461 BUFFALO

How to change the accessories (paddle, whisk, dough hook)?

Turn off the appliance, open the safety guard, lower the bowl, then push the accessory upwards then to the left to disengage it. Insert the new accessory by pushing upwards and to the right to lock it in place. Raise the bowl.

Why does the appliance not start?

Check that the appliance is plugged in and switched on, the safety guard is properly closed, the bowl is fully raised, and the stop button (GJ461) is not stuck (turn it clockwise). If the overload circuit breaker has tripped, reset it after emptying part of the contents.

How to clean the Buffalo GJ461 mixer blender?

Turn off and unplug the appliance. Wash the bowl and accessories with warm soapy water. Do not use abrasive products. Clean the exterior with a damp cloth. Never immerse the appliance.

What is the maximum capacity of flour and dough for the GJ461?

The maximum flour capacity is 7.5 kg and dough capacity is 11.3 kg for the 30-litre bowl.

How to adjust the mixing speed?

Use the gear lever located on the appliance. Always stop the mixer before changing speed. Buffalo recommends starting at speed 1 and increasing gradually.

What to do if the appliance stops due to overload?

Turn off the appliance, empty part of the bowl contents, then reset the overload circuit breaker located at the back near the cable entry. Allow the appliance to cool for 20 minutes before restarting.

How to raise the bowl correctly?

Ensure that both locking pins lock the handles against the cradle and that the protrusion at the rear of the bowl fits into the designated hole. Push the handle all the way until the bowl is fully raised, otherwise the appliance will not operate.

Can I use non-Buffalo accessories with this mixer?

Buffalo recommends using only original accessories (dough hook, paddle, whisk) to ensure safety and performance. Using unsuitable accessories may damage the appliance or cause injury.

How to maintain the mixer blender in the long term?

Regularly grease the bowl lift mechanism. Every 12 months, have the chain and belt tension checked and greased by a Buffalo agent or qualified technician.
