My wife bought this kit to use around her flower beds. Today was the first time she used it and it lasted about 30 seconds before it went up in SMOKE. Smoked so bad it made the backyard smell for thirty minutes. This must be a Fire Hazzard at the very least. Is there any way to get this replaced or repaired. She had her heart set on managing her gardens on her own and I talked her into buying Ryobi because I had 10 tools and 8 batteries already. Please let me know what can be done Thank You G.E. Cade
