Информация по безопасности

Всегда соблюдайте основные меры безопасности, чтобы снизить риск возгорания, поражения электрическим током и травм. Сохраните данное руководство по эксплуатации для дальнейшего использования.

• Безопасность рабочей зоны: Поддерживайте чистоту и хорошее освещение рабочего места. Загромождённые или тёмные места могут стать причиной несчастных случаев. Не работайте с электроинструментами во взрывоопасной среде, например, в присутствии легковоспламеняющихся жидкостей, газов или пыли.
• Электробезопасность: Вилки электроинструментов должны соответствовать розетке. Никогда не модифицируйте вилку. Избегайте контакта тела с заземлёнными поверхностями.
• Личная безопасность: Always wear eye protection, hearing protection, and appropriate respiratory protection. Use safety footwear and gloves when necessary. Stay alert, watch what you are doing, and use common sense when operating a power tool.
• Использование и уход за инструментом: Не прилагайте чрезмерных усилий при работе с электроинструментом. Используйте подходящий для вашей задачи электроинструмент. Отсоедините аккумуляторную батарею от электроинструмента перед выполнением любых регулировок, заменой принадлежностей или хранением электроинструмента.
• Безопасность аккумулятора: Use only genuine Makita batteries. Using non-genuine batteries can lead to fire, personal injury, or property damage, and voids the product warranty.

3. Регулировка защитного кожуха колеса

The tool features a toolless wheel cover (part number 123145-8) for quick adjustment. Loosen the clamp lever, rotate the guard to the desired position to protect against sparks and debris, and then tighten the lever firmly.

4. Installing Grinding/Cutting Wheels

To install a wheel, first ensure the tool is off and the battery is removed. Press the spindle lock button to prevent the spindle from rotating. Place the inner flange onto the spindle, then position the grinding or cutting wheel (e.g., 5" Depressed Centre Wheel D-20797) onto the inner flange. Secure it with the lock nut and tighten it firmly using the provided lock nut wrench (part number 782424-9).

2. Регулировка скорости вращения

The variable speed dial allows for RPM adjustment from 3,000 to 8,500. Rotate the dial to select the appropriate speed for your application. Lower speeds are suitable for polishing or delicate work, while higher speeds are for aggressive grinding or cutting.

Figure 8: Detail of the variable speed dial, allowing users to select RPM settings from 1 to 5.

3. Active Feedback Sensing Technology (AFT) and Automatic Torque Drive Technology (ADT)

This tool incorporates advanced safety and performance features:

• Технология активной обратной связи (AFT): Automatically shuts down the tool if there is a sudden drop in rotation speed, such as during a kick-back event, enhancing user safety.
• Технология автоматического привода крутящего момента (ADT): Adjusts speed and torque automatically during operation for optimal performance based on the load, ensuring efficient material removal.

4. Электрический тормоз

The integrated electric brake stops the grinding or cut-off wheel in 2 seconds or less after the paddle switch is released, contributing to increased productivity and safety.

5. Индикатор заряда аккумулятора.

The tool features a battery charge indicator to monitor the remaining battery life. Refer to the indicator lights to determine when recharging is necessary.

Обслуживание

1. Уборка

Regularly clean the tool's ventilation openings to prevent overheating. Use a soft cloth to wipe down the exterior. Do not use harsh chemicals or abrasive cleaners.

2. Бесщеточный двигатель

The brushless motor design eliminates the need for carbon brush replacement, reducing maintenance requirements and increasing motor lifespan.

3. Уход за аккумулятором

Store batteries in a cool, dry place away from direct sunlight. Do not expose batteries to water or extreme temperatures. Follow the charging instructions provided with your Makita charger.

4. eXtreme Protection Technology (XPT)

The tool features XPT, which provides enhanced protection against dust, debris, and liquids. While XPT improves durability, it does not make the tool waterproof. Avoid exposing the tool to excessive moisture.

Поиск неисправностей

• Инструмент не запускается: Ensure the battery is fully charged and properly inserted. Check that the paddle switch lock-off lever is fully engaged before depressing the paddle switch.
• Tool Stops During Operation: This may indicate activation of the Active Feedback Sensing Technology (AFT) due to a sudden drop in rotation speed (e.g., kick-back). Release the paddle switch, clear any obstruction, and restart the tool. If the issue persists, check the wheel for damage or excessive wear.
• Снижение производительности: Ensure the battery is fully charged. Check the grinding/cutting wheel for wear or damage and replace if necessary. Verify that the correct speed setting is selected for the application.
• Чрезмерная вибрация: Check if the grinding wheel is properly installed and balanced. Replace any damaged or unbalanced wheels. Ensure the side handle is securely tightened.
