Description
Overview:
The Chain Tensioner is a Genuine Echo replacement part for keeping the cutting chain correctly tensioned on compatible Echo chainsaws and pruners, including the CS-2600ES and CS-260T. Identified as OEM No. C309000030, it uses a robust metal adjuster screw and pinion to move the guide bar precisely, helping to prevent a slack chain and the associated premature wear to the bar, sprocket and chain. Built for regular use in workshop or site conditions, it offers reliable performance across the listed Echo petrol and battery models. If your existing adjuster has stripped threads, seized movement or inconsistent travel, this assembly restores smooth, repeatable chain adjustment to maintain safe and efficient cutting.
Key Features:
- Genuine Echo part for assured fit and function (OEM C309000030)
- Durable metal adjuster screw and pinion for smooth, incremental movement
- Helps maintain correct chain tension to reduce wear and improve cutting consistency
- Straightforward to fit with standard hand tools; no modification required
- Suitable for regular servicing in both professional and DIY settings
- Stable adjustment holds its setting under vibration and heavy use
- Replaces worn or stripped tension mechanisms to restore proper bar movement
- Compatible with a wide range of Echo chainsaws and power pruners listed below
Typical Applications:
Routine servicing and repair of Echo chainsaws and pruners where the chain does not hold tension, the adjuster screw is damaged, or bar movement is limited. Used after chain replacement, chain stretch, or bar changes to set and fine-tune tension for safe, efficient cutting in arborist work, landscaping, grounds maintenance, and general property upkeep.
