What to do if my GreenWorks STG401 doesn't start when I push the trigger?

If your GreenWorks Trimmer isn't starting, there could be a few reasons. First, there may be no electrical contact between the machine and the battery pack. To resolve this, remove the battery pack, check the contact, and then reinstall the battery pack. Another possibility is that the battery pack is depleted; in this case, charge the battery pack. Finally, ensure that you are pushing the lock-out button and trigger at the same time. Pull and hold the lock-out button, then pull the trigger to start the machine.
