Assembly Steps:
- Place the motor base on a stable, flat surface.
- Insert the twin gears into the juicing casing, ensuring they are properly aligned.
- Attach either the fine screen or coarse screen, depending on your juicing needs, into the juicing casing.
- Slide the assembled juicing casing onto the motor base until it clicks securely into place.
- Place the pulp outlet cap onto the end of the juicing casing.
- Position the glass juice pitcher under the juice outlet and the pulp container (not explicitly listed but implied for pulp ejection) under the pulp outlet.
- Ensure the power cord is securely plugged into a 110V electrical outlet.
Operating Instructions
Juicing Fruits and Vegetables:
- Prepare your produce by washing it thoroughly. Cut fruits and vegetables into pieces small enough to fit into the feed chute. Remove any hard pits or large seeds.
- Ensure the juice pitcher and pulp container are correctly positioned.
- Turn on the juicer using the power switch.
- Slowly feed the prepared produce into the feed chute. Use the plastic or wooden plunger to gently push the produce down. Do not force the produce, as this can strain the motor.
- The juicer will automatically separate the juice from the pulp. Continue feeding until all produce is juiced or the containers are full.
- Once finished, turn off the juicer and unplug it from the power outlet before disassembling for cleaning.
Using as a Food Mill:
The Greenstar GS-2000 can also function as a food mill for making baby food, sorbets, and nut butters. To use this feature, you may need to use specific attachments (e.g., blank screen or pasta maker attachment if available) instead of the juicing screens. Refer to the optional accessories section or specific accessory instructions for detailed guidance.
Optional Accessories:
The Tribest Greenstar GS-2000 is compatible with optional accessories such as a breadstick maker and pasta maker. These accessories transform the juicer into a versatile kitchen appliance for various food preparation tasks. Instructions for these accessories are typically provided with the accessory purchase.
Maintenance and Cleaning
Regular cleaning of your Tribest Greenstar GS-2000 juicer is essential to maintain its performance and longevity. Most removable parts are dishwasher safe for convenience.
Cleaning Steps:
- Unplug the Juicer: Always ensure the juicer is unplugged from the power outlet before cleaning.
- Disassemble: Carefully disassemble all removable parts: pulp outlet cap, juicing casing, twin gears, and screens.
- Rinse Immediately: Rinse all disassembled parts under running water to remove most of the pulp and juice residue. This prevents food from drying and sticking.
- Scrub with Brush: Use the provided cleaning brush to thoroughly clean the screens and twin gears, paying special attention to small crevices where pulp might accumulate.
- Wash with Soap: Wash all removable parts with warm, soapy water. You can also place dishwasher-safe parts on the top rack of your dishwasher.
- Wipe Motor Base: Wipe the motor base with a damp cloth. Never immerse the motor base in water.
- Dry and Store: Ensure all parts are completely dry before reassembling or storing the juicer to prevent mold or mildew growth.
