There is no other tool on the market like it. PERIOD. For anyone throwing a tantrum at the instrument itself. If you've never worked with pneumatic tools before, this tool will NOT work properly to begin with, it's most likely your own fault. I have spent almost 25 years working with all types of air tools. You need tool oil. More than "burst injection” here and there. It's impossible to avoid. Unless you're willing to hang up your $200+ instrument. Now we come to the review: From the beginning the tool seemed to be conquered. I also saw this in another review and that review actually stopped me from buying sooner than I should have. Exactly the same problem occurred to me. HOWEVER, I took my air tool oil, squirted it up the air intake tube until it started pouring back out, clicked on the air line, squeezed the scoop a little and BOOM! Since then the tool has worked great. You CANNOT lubricate these types of tools. It blows out the excess through the air vents at the bottom near the "vane". It's better to overfill than underfill with oil. I can't stress this enough. I wasted so much time not buying this product because of the negative reviews. To dig under my house, it was sent down from God. Buy a tool if you need something similar. Follow my greasing instructions. Before each use, spray oil into the air fitting until it comes out. Don't worry, be happy and God bless you!
