- Hardened Rivets: All saw chain rivets are hardened and quenched to resist wear, improve strength, and minimize chain tension changes during operation.
- Japanese Chrome-Plated Cutters: Features Japanese chrome-plated technology for superior cutter durability. Each cutter is ground and cold-headed with rotary machines for optimal sharpness.
- Защита от коррозии: Each saw chain is treated with a protective oil to resist corrosion, extending its lifespan.
2. Совместимость и идентификация
Before installing, ensure the replacement chain matches your chainsaw's specifications. Incorrect chain dimensions can lead to poor performance, damage to the chainsaw, or personal injury. This chain is designed for chainsaws requiring a 4-inch length, 1/4-inch pitch, .043-inch gauge, and 28 drive links.
Изображение: A visual guide to identifying the correct chainsaw chain dimensions, including bar length, drive links, gauge, and pitch.
How to Identify Your Chain Specifications:
- Длина стержня: Measure the exposed length of your chainsaw's guide bar. Round up to the nearest even number.
- Ссылки на диски: Count all the drive links on your existing chain. A drive link is the part of the chain that sits in the guide bar groove.
- Измерять: This is the thickness of the drive link. Common measurements are .043" (1.1mm), .050" (1.3mm), .058" (1.5mm), or .063" (1.6mm).
- Подача: Divide the distance between any three consecutive rivets by two. Common sizes include .325", 3/8"LP, 3/8", and 1/4". Note that 3/8" is typically for saws >50cc, and 3/8"LP is for smaller saws.
3. Инструкция по установке
Always refer to your chainsaw's owner's manual for specific chain replacement procedures. The following are general steps for installing a new chainsaw chain:
- Безопасность прежде всего: Ensure the chainsaw is turned off, unplugged (electric), or the spark plug wire is disconnected (gas) before beginning. Wear appropriate safety gloves.
- Удалить старую цепочку: Ослабьте гайки крепления шины и снимите крышку сцепления. Аккуратно снимите старую цепь и направляющую шину.
- Чистые компоненты: Очистите канавку направляющей шины, звездочку и зону сцепления от опилок и мусора.
- Установить новую цепь: Place the new chain around the clutch sprocket, ensuring the cutting edges face the correct direction (usually forward on the top of the bar).
- Направляющая планка положения: Fit the guide bar over the chain and the bar studs. Ensure the drive links sit properly in the guide bar groove.
- Заменить крышку сцепления: Установите на место крышку сцепления и затяните гайки крепления руля вручную.
- Отрегулируйте натяжение цепи: Adjust the chain tension screw until the chain is snug against the bottom of the guide bar, but can still be pulled freely by hand. There should be no slack on the underside of the bar, and the drive links should not lift out of the bar groove.
- Окончательная затяжка: Удерживая кончик направляющей планки поднятым, полностью затяните гайки планки.
- Смазка: Убедитесь, что масляный резервуар бензопилы заполнен соответствующим маслом для цепи и шины.

- Техника: File each cutter with smooth, even strokes, always pushing the file away from you. Maintain the correct top plate filing angle and side plate angle.
- Глубомеры: Проверьте и file the depth gauges (rakers) as needed to ensure proper chip removal.

6. Поиск Неисправностей
Addressing common issues can help maintain your chainsaw chain's performance.
| Проблема | Возможная причина | Решение |
|---|---|---|
| Chain cuts slowly or produces dust | Dull cutters, incorrect sharpening angle, worn depth gauges. | Sharpen cutters, ensure correct angles, adjust depth gauges. |
