Dopo curca 1 ore di lavoro la punta so è già rotta comw da foto allegate

Bottom bolts come out. One lost already. Lock washers do not lock them in. Heavy leak on first fill. It did even out. Careful of over filling with oil

Au bout de 8h d utilisation, le marteau piqueur fuit déjà l huile, elle coule sur le broche... Default de fabrication ou simplement du jetable ? Dommage car sinon le marteau piqueur a une bonne force de frappe et fonctionne correctement. Garantie 1ans normalement, est ce que ce genre de désagrément est prit en charge ?

Jag köpte den här maskin för att kunna spräcka sten med det gick väldigt dåligt. Jag vill retunera den här produkten. Dick Antman Valsberga Åkes Styckebruk ,

We’ve purchased many items from VEVOR and we are very happy with them and intend to continue in the future. Shipping is fast. My wife has a recent cancer diagnosis, 2 weeks later she’s in for bilateral mastectomy. We have a 9 month old German Shepherd puppy with massive energy and have yet to let her off leash. Post surgery we won’t be walking her for many weeks, we decided to fence in an area for her to run w/out taking off and ending up who knows where. We live on an 8 acre field so we picked out an area that is 100 feet long by 50 feet wide to fence in. My son and I were digging the holes for the posts when we ran into some boulders beneath the soil way too large to remove, some were only 3 - 4” deep, others were just below the surface. It ended up being on the 100’ side, It was 8 out of the 10 that had to be drilled and hammered out. While digging the holes the hammer arrived.😃! Using an SDS MAX w/1/2” X 21” bit drilling holes 12” in diameter x 18” in depth, we’d drill 6”, chisel out 3”,clean out, rinse, repeat, for all holes needing drilling. After reading the manual and post setup, we used it almost immediately. drilled holes +/-1” apart, a lot of holes to drill. 😳😤😆. The manual states that you have to put grease (oil) in the gear box before use, approximately 60g of 15W/40 hydraulic oil. There is a clear sight glass that is used as a gear box plug that threads in, it uses a rubber O-ring that functions as a seal. When viewing the oil level through the sight glass, ensuring that the hammer is standing vertical, with the bit end towards the ground, the oil should be just a very small bit below the center of the glass. After approximately 50 hours you are to open the cap and tip the hammer onto its side to drain the oil out, then refill with the appropriate oil with around 60g. The issue with the one I received is, while using the hammer, the oil would warm up, this phenomenon is normal, however during the 5th hole it began to drain out, running down the shaft of the bit through the hole where the bit is inserted and locked into place (chuck) this phenomenon is not normal🤷. Hence, we had to stop using the hammer. At first I thought that maybe it was the small amount of grease that I applied to the chuck end of the bit before locking it in place that was running out. After checking everything out this is not possible, there is too much running out and the oil keeps needing refilling after a short while, making use of the hammer extremely inefficient. The hammer arrived on 3 October 2024 and has a very small amount of time on it. This fence is critical for us to complete in a very timely manner, (before the ground freezes) the hammer is the tool that will help make this possible. We chose the 3500w model as it appears as though it is the most durable and would be the most reliable. Take away the leak, the hammer functions exactly as designed, very effective.

The package arrived with a damaged carrying case. Reached out to customer service to try and get a new storage case for it and it ended with the crediting me $47 to keep the damaged one ( I would have preferred to just have a new case) but since it was so difficult dealing with them I said screw it. Used the hammer for approximately one hour total and some seal busted and leaked a bunch of oil/grease out through the bit hole. I didn’t take any photos because I didn’t plan to do a review until they emailed asking me to.

This machine is a pain in the ass. The engagement of the machine to the tool (spade, chisel, pointer) is intermittent or nothing at all. You will wrestle with this tool trying to find the sweet spot so that the engagement consistent to finish the work. Don’t think for a minute that this tool can be used for medium or large jobs.

After a couple of days of use get broke from one of the handles

My Jack Hammer stopped working Today. Less than 30 days of Purchase

Looks good but would not start chipping mode on hard dirt. I bought it to help dig a ditch. Would not activate. Had to send back for refund
