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 55.

The same week I attempted to rotate the tires on my car using the new impact wrench and it would not even budge the nuts. I checked and double checked the torque setting and it was set on the most torque. The air compressor was more than big enough to allow the removal of the tires. I then got my 'old' impact wrench that I had for almost 30 years and it removed the tires with little effort. I often wonder why a company would give you a tool that they know is inferior and will not do the job for you when they could give you a better tool and the extra expense would pay for itself in future sales and word of mouth sales. On a positive note...the 3/8 ratchet wrench they gave me seemed to work well.

Rated 3 out of 5 by from Handy tool makes fast work of fastening and removing nuts This is my first experience with an impact wrench but found this tool easy to use. It fastens and removes nuts far faster than using a ratchet, so it will get a lot of use. It has 4 torque settings, so I was concerned that it might over tighten nuts, after all you can shear a small bolt with much less than the advertised 300 ft/lbs. Even at the maximum setting on a 1/2 inch bolt, it only took about 25 ft lbs on my torque wrench to loosen it. Impact wrenches are rated under ideal conditions including a perfectly rigid support and no elasticity or friction in the nut itself. Any flexibility will result in a loss of impact energy without adding to the final torque. Still I am surprised that this tool performed so much lower than the maximum. I did have an adequate supply of air at 90 psi, and my bolt was held in a vise on a beefy work bench and the tool was well lubricated.

Rated 5 out of 5 by from Good Light Duty tool A car mechanic would never use this tool, it's a little light weight for continuous hard use. But for the normal homeowner/hobbyist it's great. I can can change my wheels/tires over to snow tires which is why I got it, but I've also used it on tight bolts on my leaf blower and a few other things. Works great. Don't forget to oil it up before the first use (follow the directions) and then after every couple of uses. This keeps the innards from rusting. Also for really hard to crack nuts ( like lug nuts on car wheels) you need impact sockets, which are usually black and much stronger (and more expensive) than regular chromed sockets.

Rated 2 out of 5 by from Small and not very strong The Husky 1/2 in. impact wrench 300 ft-lb is the same design as the model 732 impact wrench of another company. I have done mechanic work for many years. I used to work for a railroad and worked on every thing from a 10 inch chainsaw to a D10 tractor. The hand grip is shorter and I have pretty large hands. It is not comfortable in my hand. The Husky impact is not very strong at all. It would work for passenger car wheels if they aren't rusted on. For the price I guess that you get what you pay for. I would recommend spending a few more dollars and get another impact that will do multiple jobs. I will put it in my wifes toolbox and she can use it for some small jobs.

Rated 3 out of 5 by from It's Ok The one part I did not like was the handle perhaps due to the size of my hand. However, the handle is a little short, not ergonomic, and the placement of the trigger is odd. I try using the impact wrench using my index finger but feels uneasy. So I used my middle finger - its a little more comfortable but still uneasy. Otherwise, the power is satisfactory. Strong metal casing. It is not clear why there is a bolt hole on the left side of the wrench (the manual does not reference the hole). I recommend the impact wrench for light to medium jobs.

Rated 4 out of 5 by from Good quality Impact Tried this impact first day changing out a flat tire on a small tractor. It performed very well taking the wheel off and putting it back on. I have since used it on other jobs including some rusty farm equipment. Most bolts came off eventually, but there were some it did not have enough power to loosen, had to do those by hand. It is lighter than some i have used and is easy to handle with the rubber grip and switch from forward to reverse. I would recommend this impact.

Rated 5 out of 5 by from Comfort, speed and POWER! As the title indicates this tool has up to 300 foot pounds of force - exactly what I needed to remove the bolt holding the blade on my 20 year old zero turn mower. This was a job I was dreading because I knew I could never get the leverage to remove it with my box or open ends. The tool recommends using an eight gallon compressor but my little two gallon pancake compressor was up to the job. Removing a complete set of lugs from a car would probably require that. There is a push button above the trigger to select forward or reverse and the handle is coated with comfortable rubberized material which keeps the vibration from hurting your hands. It really turns fast too - 7500 rpm with no load. It also comes with a protective storage bag. I'll be using this tool for those "can't get them off" or "can't get them on tight enough" jobs from now on.
