What causes a DeWalt cordless blower to cycle on and off?
The cycling of a DeWalt cordless blower is often due to overheating. When the motor reaches a certain temperature, a built-in thermal overload protection feature kicks in to prevent damage. This safety mechanism turns off the blower temporarily until it cools down. If you notice this happening frequently, it may indicate that the tool is being used for too long without breaks or that the environment, such as outside temperature, is affecting its performance.
Another common cause of this issue is a low battery charge. If the battery is nearing the end of its capacity, it may not provide consistent power to the motor, leading to intermittent operation. Make sure to fully charge the battery before using the blower and consider replacing it if its performance seems compromised, as older batteries tend to have diminished power output.
