Operating Instructions
Prepare your fruits and vegetables by washing them thoroughly. The 3-inch wide feed chute can accommodate whole fruits and vegetables, but larger items may need to be cut into smaller pieces to fit.
Speed Settings:
- Low Speed (12000-15000 rpm): Ideal for softer fruits and vegetables such as oranges, grapes, tomatoes, and leafy greens.
- High Speed (15000-18000 rpm): Recommended for harder produce like apples, carrots, celery, and beets.

Juicing Process:
- Plug the juicer into a grounded electrical outlet.
- Select the appropriate speed setting (Low or High) using the switch on the front of the motor base.
- With the motor running, slowly feed the prepared fruits and vegetables into the feed chute using the pusher. Apply gentle, even pressure. Do not force the produce.
- The juicer will automatically separate the juice into the juice jug and the pulp into the pulp container.
- Once juicing is complete, turn the switch to the "OFF" position and unplug the appliance.
A helpful chart is included in the full instruction manual to guide you on the quantity of fruits and vegetables needed to produce juice and pulp.

Troubleshooting
If you encounter issues with your Mueller Juicer, please refer to the following common troubleshooting tips:
- Juicer does not turn on:
- Ensure the power cord is securely plugged into a working outlet.
- Verify that the locking arm is fully engaged and secured. The juicer has a safety interlock system.
- Check if the overload protection feature has activated. Unplug the unit and let it cool down for at least 10 minutes before attempting to use it again.
- Low juice yield or wet pulp:
- Ensure the filter basket is clean and free of clogs. A dirty filter can reduce efficiency.
- Use fresh, firm produce. Overripe or soft fruits/vegetables may yield less juice.
- Feed produce slowly and apply gentle, consistent pressure with the pusher.
- Ensure the correct speed setting is selected for the type of produce being juiced.
- Excessive vibration or noise:
- Ensure the juicer is placed on a stable, flat surface.
- Verify that all components are correctly assembled and securely locked.
- Check for any foreign objects in the filter basket or feed chute.
