Description
Guide bar nuts (2x) fits Echo CS-352, CS-353 (ES) and Shindaiwa 340S chainsaws. These nuts thread onto the bar studs to clamp the guide bar and clutch/sprocket cover firmly against the engine casing, keeping the bar correctly tensioned and aligned during cutting. When the nuts strip their threads, corrode, or lose grip, the guide bar cover can no longer be tightened securely, leading to a loose bar, inconsistent chain tension or the cover working loose during use. Fitting a replacement set of guide bar nuts restores a secure clamp on the bar and cover.
