I like it had oil reservoir with a wick ( has good power busts up concrete with ease, putting in a pond and have what I’m going to call decomposed granite rocks to much to dig out have to bust up first this works great

Lo recomiendo es una pasada por el precio k tiene muy buena calidad en sus materiales

Happy

No he visto muchos martillos de este tipo pero para hechar piedras abajo y tierra dura va perfecto y tiene bastante fuerza, para mí una buena compra

Un peu lourd normal vue la puissance

the product came with no manual, instruction or anything telling you anything but a general don't use underwater warning. what oil or grease to use,,when or where. other than that it comes with all the different attachment and tools you need. overall a good deal but they really need to either put in some paperwork or a site you can reach.

I live in an area with mostly solid lava-rock soil. I set fence posts and dig ditches through solid rock, and am very hard on jackhammers. This hammer has 3 main issues, (which, considering its price point, are not impossible to deal with: 1) It's own vibration will keep you stopping to re-torque its capscrews (see pics) 2)It will very shortly exude oil down the hammer shaft and all over the ground and you. (keep at least chain-saw oil handy. and 3) You will doubtless (too keep it in service) have to use helicoils or some other re-threading mechanism to keep its bolts in place. For the money invested, I've done A LOT with this hammer, especially considering that comparably performing hammers rent for @ $120/day at Home Depot, etc.

Many years ago my first job was working for a concrete company. I’ve spent many hours behind industrial jack hammers so perhaps this review will help your decision in purchasing this jack hammer.So for two hundred bucks I believe you’ll definitely get your monies worth. I used mine to break up a 70 year old driveway under a carport that had tree roots starting to break it beyond repair. The slab was approx. 4 yards worth of concrete.This machine gets hot but takes a while to get there. I’d take a 10-15 minute break every hour and place the hammer in front of a fan to help it cool off. I wanted to be sure not to burn it up. I broke the tip of both bits fairly quickly but it seemed to have no real effect on the hammer. Just had to bend over an extra inch or so.I’m 6’ tall and it’s hard standing upright while using this.IMPORTANT!!!! After my second hour of using the hammer I noticed on the ground a new looking allen head bolt directly underneath where I was working. I stopped immediately to check the hammer to see if said bolt fell out. Sure enough it had come from the hammer. I also noticed all the allen headed bolts located on the collar of the bottom of the hammer were either on the verge of coming out or extremely loose! So I’d advise before it’s first use make sure to tighten ALL FASTENERS on this machine! I’m not sure what would’ve happened if they all would’ve fallen out but I’m sure it wouldn’t have been pretty.There’s a site glass on the outside of the machine that tells you how much hydraulic oil is there. Besides the site glass is a sticker that advises to fill with hydrolic oil before first use. I did not have to fill it as it was already completely full.Anyway other than loose bolts this machine did exactly what I needed it to do. Saved myself about $600 in labor by busting up the old driveway.

Great for breaking up old foundation.

I've used it three times. Used 2 hours each day and it works great. Took out some stairs to to no where. Didn't have any problems with the hammer.
