Setup
Your TIMEMORE Chestnut C5ESP grinder comes pre-assembled. Before first use, it is recommended to disassemble and clean the components to remove any manufacturing residues. Refer to the 'Maintenance and Cleaning' section for detailed cleaning instructions.
Component Identification

Initial Assembly (if disassembled)
- Ensure all components are clean and dry.
- Place the inner burr onto the central shaft, followed by the spring and washers.
- Screw the adjustment dial onto the shaft, ensuring it engages with the inner burr.
- Attach the catch cup to the bottom of the main body.
- Place the lid on top and insert the handle.
Operating Instructions
1. Adjusting Grind Coarseness
The C5ESP features a precise adjustment dial located at the top of the grinder. The dial can be adjusted by 50 bars in 1 turn, offering an adjustment accuracy of 0.015mm per grid for fine-tuning your grind.

To adjust the grind size:
- Hold the grinder firmly.
- Turn the adjustment dial clockwise for a finer grind and counter-clockwise for a coarser grind.
- Refer to the recommended settings below for common brewing methods.
Recommended Grind Settings (C5 ESP)

- Espresso: 0.5-1.2 turns (approximately 5-8 large grids)
- Pour-over: 1.5-2.0 turns (approximately 10-14 large grids)
- French Press: 2.0-2.4 turns (approximately 14-17 large grids)
Note: When the pointer and the dial rotate at 0 points, there may be an error of about 2 small squares, which is a normal phenomenon. These settings are a starting point; adjust to your preference.
2. Adding Coffee Beans
The bean bin can hold approximately 30g of coffee beans. The funnel-shaped opening and expanded design reduce spillage and make pouring easier.

3. Grinding Coffee
Once the beans are added and the grind size is set, place the lid and handle. Hold the grinder firmly by its textured body, which provides a tight hand grip, and turn the handle clockwise to begin grinding.

4. Collecting Ground Coffee
After grinding, unscrew the catch cup from the bottom of the grinder to access your freshly ground coffee.
Maintenance and Cleaning
Regular cleaning ensures optimal performance and longevity of your grinder. The grinder is designed for detachable deep cleaning.

Important: It is forbidden to wash the grinder with water.
To clean your grinder:
- Disassemble the grinder by unscrewing the catch cup, removing the handle, lid, and then carefully detaching the burr assembly.
- Use a cleaning brush (often included with the grinder) to remove any residual coffee grounds from the burrs, shaft, and internal components.
- Wipe the exterior with a dry or slightly damp cloth.
- Ensure all parts are completely dry before reassembling.

Troubleshooting
While the TIMEMORE Chestnut C5ESP is designed for reliable performance, here are some general troubleshooting tips:
- Grinder feels stiff or hard to turn: Check if the grind setting is too fine, especially for very light roasts. Try a slightly coarser setting. Ensure no foreign objects are in the bean chamber.
- Inconsistent grind: Ensure the burr assembly is properly seated and tightened. Clean the burrs thoroughly to remove any accumulated oils or fine particles.
- Coffee beans not feeding: Make sure the bean chamber is not overfilled. Gently shake the grinder to help beans settle into the burrs.
