Ryobi Ryobi RY40550 40V HP Brushless 14 in. Chainsaw TOOL OVERLOAD Error Fix: Tool Overload Protection — Motor Overcurrent

Error code TOOL OVERLOAD on the Ryobi Ryobi RY40550 40V HP Brushless 14 in. Chainsaw means: Tool Overload Protection — Motor Overcurrent. The tool has activated overcurrent protection and shut down. On tools with an LED indicator, a blinking red LED may be visible. This occurs when the motor draws more current than the controller can safely deliver — typically because the motor is stalled or encountering extreme resistance. Common triggers by tool type: Chainsaw — chain pinched in a cut, chain too tight, chain brake accidentally engaged. Mower — blade hitting a stump, rock, or extremely thick/wet grass. Trimmer — trimmer line jammed or caught on a solid object. Blower — foreign object lodged in the impeller. Release the trigger and wait 10-15 seconds for the controller to reset. Remove the obstruction or cause of the stall before restarting. If the tool immediately shuts down again with no visible obstruction, check that the battery is adequately charged (a low battery combined with a heavy load can trigger overcurrent). If the problem persists with a fully charged battery and no load, the motor or controller may have a fault requiring warranty service.
