Where and when do I add the oil

This question is from 1/2 in. 300 ft. lbs. Impact Wrench
Asked by
Anonymous
January 10, 2015
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

Answer: 
The port is a vent port where oil sprays out. You only need to add a few drops to the air coupler each time you use the tool which, by the way, I recommend you do with all your air tools.

Answer: 
You will never have to add oil to the side of the gun. (Only required after hundreds of hours of usage) The oil that were are referring to in the manual, that must be strictly adhered too, is the air tool oil into the inlet of the tool. This keeps the tool lubricated and prevents rust from forming inside the tool. Compressed air is very hot when it enters the compressor tank, when it cools it forms water Read More
You will never have to add oil to the side of the gun. (Only required after hundreds of hours of usage) The oil that were are referring to in the manual, that must be strictly adhered too, is the air tool oil into the inlet of the tool. This keeps the tool lubricated and prevents rust from forming inside the tool. Compressed air is very hot when it enters the compressor tank, when it cools it forms water which is then blown through the tool. When the water sits inside the tool rust forms and the tool will not operate anymore. So if you or your friends have a tool that just blows air threw the tool when the trigger is pulled, this is what happened. Read Less

Answer: 
Hello jawojnicki,
The only oil you should be concerned about would be the inline filter regulator lubricator as shown on page 7 of the owners manual. The other port you are asking about is for professional maintenance providers only.
Thank you for your inquiry.

Answer: 
Yes. before trying, make sure you run the gun full open by the compressor regulator gauge and set the regulator to 90 PSI with the tool running full speed. This will insure that you are getting the full 90 PSI required at the tool. once set, when you let off the trigger the gauge will jump higher but do not adjust as when you pull the trigger it will fall back to 90 PSI. If you are not able to get to 90 Read More

If you are not able to get to 90 PSI based on the above scenario then you need a larger compressor that provides more SCFM per minute. Also please use plenty of "air Tool" oil in the air inlet to keep the tool well lubricated and avoid rusting of internal parts. Read Less

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.

Answer: 
You could try clicking through the power settings and flipping the forward/reverse switch a few times, but it sounds as if something's seized up and that you may be better off bringing it back to the store for a replacement. Make sure to oil through the air line before operation!

Answer: 
Do you mean wobbly on the connection to the wrench, or wobbly on the connection to the bolt?
A little wobble on the wrench is ok, just make sure that you're using impact-rated sockets which are usually black. The chromed ones may shatter under load.

Rated 5.0 out of 5.0 by very satisfied serves purpose it was purchased for would recommend to others September 6, 2016
Rated 1.0 out of 5.0 by Not very impressed Bought his air wrench on sale at Home Depot a while back. I have plenty of experience with air tools since my father and I had a car lot years ago. This air gun is just a cheap piece of junk. This air impact gun, although not very powerful, worked until the other day when I could not break loose the blade retaining nuts on my riding mower. Yes, the settings on the gun and the air pressure was correct. It seemed that most of the air was was going through the bypass valve, the valve that adjusts torque. I've had it about 11 months, but have only used it about a dozen times, always using oil. In comparison, my father has a Ingersol Rand air impact that I purchase USED in 1994; it still works perfect. It has probably been used thousands of times! I am going to exchange this piece of junk for the 800 ft/lb impact today. To me, it is worth the extra $80 for a much more powerful gun that, according to the reviews, just works! April 1, 2016
Rated 5.0 out of 5.0 by Helpful tool Quick and easy. I used it to help zip lug nuts off my cars for brake jobs and tire swaps. Has no problem pulling them off small passenger cars, and that was with a small Porter-Cable 6 gal 150 psi pancake compressor. I'm sure that it wouldn't help bust loose a stuck bolt, especially not with my tiny compressor, but that's where my breaker bar or my cheater pipe come in. I just wanted something that would zip off bolts when the wheels are in the air that wouldn't rotate the wheels. For that, it's perfect. It has 4 power settings. Make sure that you tighten using the lowest setting and then use a torque wrench afterwards to make sure everything is to spec. October 20, 2015
Rated 4.0 out of 5.0 by Not bad for the low price Let's face it, this tool sells for about 1/10 the price of a profession grade tool of the same size and capacity. So it would be unreasonable to assume it comes close in quality or reliability. Still, I think it is a reasonable light duty infrequent-use tool. Don't expect to use it for an everyday business. I noticed no abnormal operation during the fairly brief two weeks of time I have used it so far, although to be honest, nothing over a torque setting of 2 (or maybe 100 lb-ft?). It worked well with a small 6-gallon compressor, rated at 4 cfm. The tool weight is about what you would expect for this size, actually a little on the light side at 4.77 lbs. Attaching and removing the sockets was a bit difficult, as expected, since I did not want to oil the anvil as some folks do. I don't want one to come off while under torque. The manual says to pull off the bit with your hands ...or use a suitable tool. I used an ordinary screwdriver to pry them off. The direction control was also somewhat difficult to operate at first. I can't stress the importance of oiling the tool frequently. As a matter of fact, I think that should have been the very first step in the manual, since the tool will have been unused in storage for an unknown length of time. The inline oiler, which you should always use, would not be adequate to prepare the tool for first normal use. I would have liked to have seen a chart of torque/setting/psi values, but I suppose that would be asking too much. I do like the labeling of the direction switch (F--R) in "English" instead of universal symbols. Also, don't lose the black bag that comes with the tool. Use it always to keep the oil from drying too quickly. February 5, 2014
Rated 1.0 out of 5.0 by Looks like a solid tool, just don't try to use it. On the first try, this thing couldn't break loose lug nuts on a car that I'd previously installed without power tools, and nearly always park inside so it's inconceivable that there's any rust to deal with. On the second try, the trigger/valve jammed open and I had to pull the air hose out to get it to stop spinning. This was the first time I'd attempted to use the tool, and oiled it just before hooking it to the compressor. About the only thing which went how it was supposed to was installing the quick-connect fitting into the connector. October 5, 2015
Rated 1.0 out of 5.0 by Unfortunately, the bad reviews are true I bought this as a combo with the air ratchet because I figured it couldn't be that bad for the price. Unfortunately, it was. I set out to do the brakes on my truck and at even the highest torque setting, it couldn't break the lug nuts loose. The lugs were at 105 ft. lbs...just shy of 1/3 what this is supposedly rated for. I wasn't expecting this thing to compete with an IR or Snap On, but I was at least expecting it to be as advertised. Needless to say, I will never buy another Husky air tool. October 2, 2015
