4. Інструкції зі встановлення

Replacing carbon brushes is a common maintenance task for power tools. Always refer to your specific tool's service manual for detailed, model-specific instructions. The following are general guidelines:

1. Безпека перш за все: Disconnect the power tool from its power source (unplug it or remove the battery pack) before beginning any maintenance.
2. Знайдіть ковпачки для щіток: Identify the brush caps on your power tool. These are usually small, slotted or Phillips-head caps on the side of the motor housing.
3. Видаліть старі пензлі: Unscrew the brush caps and carefully pull out the old carbon brushes. Note their orientation.
4. Перевірте колектор: While the brushes are out, inspect the commutator (the copper segments on the motor's armature). It should be clean and free of excessive scoring or carbon buildup.
5. Вставити нові пензлі: Insert the new Makita CB70 carbon brushes into the brush holders, ensuring they are oriented correctly. The carbon block should slide smoothly into the holder, and the spring should apply pressure to the brush.
6. Надійні ковпачки для щіток: Screw the brush caps back into place, tightening them securely but not overtightening.
7. Тестовий інструмент: Reconnect the power tool to its power source and test its operation. It may take a few seconds for the new brushes to seat properly, which might result in some initial sparking. This is normal.

If you are unsure about any step, consult a qualified technician or the tool's official service manual.

5. Operating Considerations After Brush Replacement

After installing new carbon brushes, it is important to allow them to "seat" properly against the commutator. This process ensures optimal contact and performance.

• Початкове обкатка: Run the tool at a moderate speed without load for a few minutes. This helps the brushes conform to the shape of the commutator.
• Observe for Sparking: Some minor sparking at the commutator is normal, especially with new brushes. Excessive sparking, smoke, or unusual smells indicate a problem and the tool should be immediately shut off and inspected.
• Регулярне використання: Continue to use the tool as intended. The brushes will continue to wear and conform over time.

6. Технічне обслуговування та догляд

Proper maintenance of your power tool, including its carbon brushes, extends its lifespan and ensures safe operation.

• Регулярна перевірка: Periodically inspect the carbon brushes for wear. They should be replaced when they are worn down to approximately 1/4 inch (6mm) or less, or if they appear chipped or damaged.
• Тримати в чистоті: Ensure the brush holders and commutator area are kept clean and free of dust and debris. Use compressed air to blow out carbon dust if necessary.
• Використовуйте оригінальні запчастини: Always use genuine Makita replacement parts, such as the CB70, to ensure compatibility and maintain the tool's performance and warranty.
