Customer Reviews for VEVOR Demolition Jack Hammer Jack Hammer Concrete Breaker 1200 BPM Heavy Duty Electric Jack Hammer 3 Chisel Bit W/Gloves & 360° Swiveling Front Handle for Trenching, Chipping, Breaking Holes
I am using this to open up cracks in concrete driveway for patching and resurfacing. Not bad. However it did not come with manual. Was searching web to see how to use a similar tool. Useful tips plus I found out I had to add oil. Nothing about adding oil came with product.
I was in the construction industry for 12 years, this has a metal casing and works as good as any I've ever used. Would be nice if they would recommend what oil to use, most people wouldn't know.
