Customer Questions & Answers

Where and when do I add the oil

This tool has a port on the right side (if you're looking at it from behind) labelled "oil" and there is obviously a plug under the word oil that can be removed with an allen wrench. The instruction manual DOES NOT address what this port is used for! It shows oil being added to the air intake port UNDER THE HANDLE but does not explain anything about the "oil" port on the RIGHT SIDE of the body of the wrench. PLEASE: What is this port used for? When should I add oil into the port instead of adding it to the air intake on the bottom of the handle? THank you
Asked by: Anonymous
According to what I have been told and the directions, you add a predetermined number of drops on a daily basis into the air connection that is screwed into the tool handle. There is a special tool oil manufactured but for the most part I just use 20 -30 weight electric motor oil.

Will it remove lug nuts

Asked by: Lisa
Mine did not. It was new, out of the box, with the torque setting set to the most torques. The impact wrench would not even begin to remove any of the lug nuts for removal.

Which socket to attach?

I tried Husky sockets from HD & they were wobbly.
Asked by: soch
I would not use wobbly sockets, they may fly off and hit you. I would think a quality brand name socket would fit snugly and give good service. As another user said, you may want to try the heavier impact sockets. If they don't work take back the impact wrench and/or sockets. We work hard for our money and should not pay money for items that do not work.

How do i get it to operate?

I just bought one of these and hooked it up. It operated normally for a few seconds. Then when I tried again, it just blows air through. I even added more oil in the port and the air line. Still nothing.
Asked by: ACC
Dear ACC, Make sure that the forward/reverse button is fully seated in the position you select. Try connecting and disconnecting the air hose a couple of times then trigger it. Also be sure that your compressor is delivering enough pressure to make the tool operate. If your problem continues take the tool back to your Home Depot and request a test or replacement. Those folks are good about making it right. Sincerely, hamrdul

1/2 in. 300 ft. lbs. Impact Wrench is rated 2.7 out of 5 by 59.
Rated 1 out of 5 by from Impact Did not deliver the 300 ft lbs as advertised. This is not a powerful tool

Rated 3 out of 5 by from I needed an impact driver to remove the blades under... I needed an impact driver to remove the blades under my riding mower. The price was just a little more than what I paid to rent one before, so I figured I'd try it. It works fine, but didn't have enough muscle to break the nut loose. I had to use a breakover bar with cheater. The impact did the rest, no problem. I guess I should've sucked it up and gotten the next larger one, but there was a significant price jump. I'll try it on tire lug nuts next. If it doesn't break those loose I wasted my money.

Rated 4 out of 5 by from Not bad Bought a set of air tools and this was included in the package. Decent impact wrench for what i needed it for. First attempt at using, i felt it was underpowered and like other reviews, thought the rated 300lbs of torques was a sham. Had an inline oil fogger hooked up and thought i was good to go. But after reading the instructions, i properly oiled it for first time use and ran it for about 30 seconds and it came to life. Used it to remove my Ducati 1199 rear axle nut and that sucker was torqued down by Hercules, but after about a minute or two of spread bursts I was able to spin it off, so not sure if 300lbs of torque is accurate but specs to torque my Ducati rear axle nut is at about 170-180lbs of torque. So I relieved that it wasn't junk like the reviews say. Not sure about durability, i'll try it out on my truck lug nuts one day but I say with regular maintenance and care, it should perform well. Here is to hoping.

I'm sure I'll need it in the future.It does not come with a 1/2" to 3/8" socket adapter so you'll need one if your sockets are all 3/8" like mine.
