At 80 yrs old the old my 16", heavy, 15 yr old 2 cycle would not start. God said no y'all both too old for this stuff, Thank you Lord. So this light little thing is easily cut through a 4" fallen limb. The chain will stretch a little at first use and will need to be tightened. Taking it apart and managing to put it back together is difficult for old hands, besure to remove battery first. tie the guard back and keep trying. I've got trees to trim this winter and no saving and mixing gasoline. When the day is right and this old body is ready, grab it and trim. Blow off with air , charge battery, come back in house for a cup and store away.
