5. Operation
Operating your OSTBA Stand Mixer is straightforward. Always ensure the mixer is properly assembled and locked before starting.
5.1 Speed Control
The mixer features an 8-speed control knob with a pulse function. Turn the knob clockwise to increase speed. The 'P' setting activates the pulse function for short bursts of power.

5.2 Using Attachments
- Dough Hook (Speeds 1-2): Ideal for kneading yeast doughs for bread, pizza, and pasta. Start at a low speed and gradually increase as the dough forms.
- Beater (Speeds 1-6): Suitable for mixing cake batters, cookie dough, frostings, and mashing potatoes. Use lower speeds for initial mixing and higher speeds for thorough blending.
- Wire Whip (Speeds 6-8): Best for aerating ingredients like egg whites, cream, and light batters. Use high speeds to achieve desired consistency.
Always add ingredients gradually through the splash guard's pouring chute to avoid mess.
