What to do if grass winds around the GreenWorks STB409 Trimmer head?
If the grass winds around the trimmer head and motor housing of your GreenWorks Trimmer, cut tall grass from the top down, removing no more than 8 inches in each pass. This will help prevent the grass from wrapping around the trimmer head.
What to do if the line does not advance on GreenWorks STB409 Trimmer?
If the line on your GreenWorks Trimmer isn't advancing, several factors could be at play. The lines might be welded together, in which case you should lubricate them with silicone spray. Alternatively, the spool may not have enough line, so install more. If the lines are worn too short, advance the cutting line by bumping the trimmer head. Finally, the lines could be tangled on the spool; remove them and wind them properly.
Why my GreenWorks STB409 Trimmer does not start?
If your GreenWorks Trimmer doesn't start when you push the trigger, it could be due to a few reasons. First, ensure there's good electrical contact between the machine and the battery pack by removing the battery and reinstalling it. Next, check if the battery is fully charged. If not, charge it. Lastly, make sure you're properly engaging the lock-out button and trigger simultaneously. Pull and hold the lock-out button, then pull the trigger to start the trimmer.
Why does the line keep breaking on my GreenWorks Trimmer?
If the line on your GreenWorks Trimmer keeps breaking, it may be due to incorrect usage. Try cutting with the tip of the line, avoiding hard objects like stones and walls. Also, advance the cutting line regularly to maintain a full cutting width.
Why GreenWorks STB409 Trimmer vibration increases obviously?
If the vibration increases obviously on your GreenWorks Trimmer, it might be because the line is worn down on one side and hasn't been advanced in time. Ensure the line on both sides is normal and advance the line as needed.
How to sharpen GreenWorks Trimmer blade?
If the line on your GreenWorks Trimmer doesn't cut well, the cut-off blade may have become dull. Sharpen the cut-off blade with a file or replace it.
