  If your GreenWorks Trimmer doesn't start when you pull the trigger, there are a few things to check: First, ensure there's good electrical contact between the battery pack and the machine by removing and reinstalling the battery pack. Next, make sure the battery pack isn't depleted; if it is, charge it. Finally, confirm that you're properly engaging the lock-out button and trigger simultaneously.

What to do if the line does not advance on my GreenWorks G40LT30 Trimmer?

  If the cutting line on your GreenWorks Trimmer isn't advancing, a few things could be the cause. The lines might be welded together, so lubricating them with silicone spray can help. You might not have enough line on the spool, so install more line. The lines could also be worn too short, so try advancing the cutting line. Alternatively, the lines might be tangled on the spool; remove them and rewind them.

Overheating of either the battery pack or the machine itself can also cause it to stop; allow them to cool down. The guard might not be attached properly, so remove the battery pack and attach the guard. Check if the grass winds around the motor shaft or the trimmer head, and if so, stop the machine, remove the battery pack, and clear away the grass.
