Why GreenWorks STF309 Trimmer does not start?
If your GreenWorks Trimmer doesn't start when you push the trigger, first, remove the battery pack and check the contact, then reinstall it. If that doesn't work, charge the battery pack. Also, make sure you are pulling the lock-out button and the trigger at the same time.
What to do if my GreenWorks STF309 Trimmer stops when I cut?
If the GreenWorks Trimmer stops while you're cutting, there could be several reasons. Ensure the guard is attached to the machine. Also, verify you're using the correct nylon cutting line of 0.065" (1.65 mm) diameter. Check if grass is wound around the motor shaft or trimmer head, and remove it if so. If the motor is overloaded, remove the trimmer head from the grass to allow it to recover. If the battery pack or machine is too hot, cool them down. Make sure the battery pack is properly connected and charged.
How to fix GreenWorks Trimmer line not advancing?
If the line on your GreenWorks Trimmer isn't advancing, it could be due to several reasons. The lines might be welded together, in which case you should lubricate them with silicone spray. It's also possible that there isn't enough line on the spool, so install more line. If the lines are worn too short, advance the cutting line. Finally, the lines might be tangled on the spool; if so, remove them and rewind them.
Why does the line keep breaking on my GreenWorks Trimmer?
If the line on your GreenWorks Trimmer keeps breaking, it's likely due to incorrect usage. Cut with the tip of the line, avoiding stones, walls, and other hard objects. Regularly advance the cutting line to maintain a full cutting width.
Why GreenWorks STF309 line does not cut well?
If the line on your GreenWorks Trimmer isn't cutting well, the cut-off blade may be dull. Sharpen it with a file or replace it.
What causes increased vibration in my GreenWorks STF309?
If the vibration of your GreenWorks Trimmer increases noticeably, it could be because the line is worn down on one side and not advanced in time. Ensure that the line on both sides is normal and advance the line.
