Engine
If the pole saw chain will not stop turning even when the throttle is released, it is probably because the idle speed of the engine is set too fast. The crankshaft spins inside of the clutch without the clutch catching and starting to spin as well, until a certain amount of speed is achieved. Once it reaches this speed, the clutch engages and forces the chain to rotate. When the throttle is not engaged, the engine should idle at a slow enough speed so that the clutch does not engage and start driving the chain. If the chain rotates while the engine is idling, adjust the carburetor on your engine to slow down the idle speed.
Clutch
If you have adjusted the idle speed of your engine and the chain continues to rotate after the throttle has been released, there is likely an issue with the clutch. If a clutch becomes dirty or the springs break, the mechanism that engages and disengages the clutch, depending on the rotational speed of the crankshaft, may not work, which can cause the chains to rotate even after the throttle is released. To inspect the clutch, remove the front motor housing and the clutch drum to inspect the clutch. If the clutch pads are worn or if the springs are worn, the clutch will likely need to be replaced. This mechanism does wear over time from regular use and should be inspected and cleaned on a regular basis. Refer to your user manual for the proper replacement part numbers if a new clutch is required.
