Furthermore, regularly inspect the power cord and plug for any signs of damage, and ensure they are kept in good condition. The cutting blades are consumable items and will require replacement over time. Monitor their condition and replace them when they show signs of wear, such as reduced cutting speed or increased effort required to make a cut. Adhering to the manufacturer’s recommended maintenance schedule, which often includes checking brush wear and lubricating moving parts if applicable, will significantly contribute to the tool’s durability and reliable operation.
