Why is my GreenWorks STF457 line not cutting well?
If the line on your GreenWorks Trimmer isn't cutting well, the cut-off blade may have become dull. Sharpen the cut-off blade with a file or replace it.
What to do if my GreenWorks Trimmer stops while cutting?
If your GreenWorks Trimmer stops while you're cutting, there could be several reasons. First, ensure the guard is properly attached. If you're using heavy cutting line, switch to a 2 mm diameter nylon cutting line. Grass winding around the motor shaft or trimmer head can also cause this; stop the machine, remove the battery, and clear any grass. Overloaded motor is another potential cause; remove the trimmer head from the grass, and it should recover. When cutting, move the trimmer head in and out of the grass, removing no more than 20 cm in a pass. Overheating of the battery pack or machine can also cause the tool to stop. Cool the components and try again. Ensure the battery pack is correctly installed and charged.
