Query: demolition hammer

That's my third bosch hmmer i have. It works more hours then they say. I had a tear out job- over 3000 sf of slate, worked 10 hours per day for a week or so. Had to use gloves because mammer was so hot.So i used that hammer for 4 years on and off and it finally stop hammering, just drilling ,then i took to repair shop and they told me about $300 bucks to fix it. So i bought this one ( hammer only), a week later i got my old one back with old parts put together. When i turned on it start hammering again, now i am going to use my old one until i kill it all the way.
