What to do if DeWalt Trimmer cutting head will not advance line?
- KKaren LewisAug 4, 2025
If the cutting head of your DeWalt Trimmer won't advance the line, the following issues might be the cause: * The cutting head is bound with grass. Stop the engine and clean the cutting head. * The cutting head is out of line. Refill the cutting head with new line. * The inner reel is bound up. Rewind the line. * The cutting head is dirty. Clean the inner reel and outer spool. * The line is welded. Open the cutting head and remove the welded section. * The line is twisted. Rewind the line. * Not enough line is extended. Stop the unit, push the bump knob and pull the line until 4 inches (102 mm) is outside of the cutting head.
