I just inherited one of these from my father in law's garage... he's been gone for 10 years now and its been put away. Thanks for the tips!
Glad you found this video useful!
Thanks for taking the time to make this video!👍🏾
Thanks for watching and commenting! Glad you found this useful!
Thank you thank you thank you. My neighbor borrowed mine, broke it, I wasted this video and I fixed it myself… the fan was stuck but I thought it was that he ran it without oil… now I need to do is replace the drain plug cuz he broke that… Thank you for saving me hundreds
That's what these videos are here for to hopefully help people and save money and fix things 😁. Thanks for watching and commenting! Glad you fixed it!
very helpful..I have tge 150 and 37 hrs with no oil change will do now and many thanks
Great to hear! Glad this video was useful. That's some great usage out of these, mine is still going strong all these years later. Thanks for watching!
Great video. Also make sure to level the unit before filling with oil to get correct level. My barn floor was way off so I moved it to concrete floor in my basement and its level now :D
Everyone assumes floors are always flat 🤣. Lol. Thanks for watching!
I e got an Allen key for oil drain
THANKS FOR THE TIPS. GOD BLESS.
Thanks for finding my channel and thanks for watching!!
I have the red one for 10 years now. Haven't used in awhile. Will be using again soon fos a deck framing nailer. Gonna do the maintenance as you described. Muchas gracias
Air compressors are so useful. Wish I had a garage to put one in. I would get a lot of use with one. Harbor freight always has good deals on on cheap tools.
Oh yeah HF is always my go-to first if I can save some money. I research their stuff first so I avoid the crappy products lol. But overall I’ve been very satisfied. And besides my shop vac this air compressor probably sees more use than any other tool in my garage. You can probably find a nice portable one that you can haul out when you need it. Some of the new ones that are only like 5 gallon capacity are actually pretty decent now and can keep up with basic tools like blow guns and inflators.
Thanks for the video! Gonna switch mine to synthetic
It makes a big difference IMO. Thanks for watching!
Same here.
I have to drain mine very soon but this gave me the idea that I will switch out that original drain screw with either a hex or allen head screw.
At an easy upgrade just make sure you match the threads correctly. Thanks for watching!
@@DIYDad1 yes absolutely
I use mobile 1 oil it works for me
My grandfather had this compressor for years with no maintenance then I ended up inheriting it and have been running it for the last 4 years with no maintenance. It's been pretty good to me. I'm goona change the oil tonight
These things do run a long time even when neglected! HF has surprised me many times. Thanks for watching!
The reason I'm asking is because although the psi is high enough the SCFM has to be at least 5 to use an impact wrench. Is this guy confused or am I?
@@jamesmitchell2804 no your absolutely right because my impact wrench is rated at 5.3 scfm but the compressor only outputs at something like 4.7 if I remember correctly. This simply means it cannot sustain 90 psi at that cfm forever. But because it has a large tank, I'm able to remove at least two tires worth of lug nuts before the output pressure from the regulator drops low enough and the tank has to recharge. There's enough of a reserve there that you can run larger tools, albeit intermittently, without the compressor running constantly. Now this is fine for tools like impact wrenches where you aren't hammering on the trigger constantly. But you definitely need a higher cfm for constant demand tools with things like paint sprayers. Hope that makes sense!
how do I " drain air from tanks" ? A dum ?
I can not see through the little window on mine so i just added a 1/2 cup or so. Is there any way to pull that window and clean it ? It looks like it would take a socket ?
Haven't tried to but I would think you could flush it a couple of times with a few drain and refills hope it clears up I haven't tried. I wish there was a small dip stick for these.
Can you run a pneumatic impact wrench to take the lug nuts off a car tire with this thing?
Yep! I use one frequently with mine. Use it for rotating tires all the time. I can usually do two tires before the air compressor kicks in again to recharge. It's been great for automotive work.
I’ve noticed that mine leaks down the same side of the tank as the window. Any ideas as to why ?
Is it leaking out the top filler hole or somewhere else? Could be a leaky worn gasket where the oil is.
I have the same compressor and have the stupid oil leak through the breather, I replace both the piston and rings, but didn't fix it unfortunately
Dang, I'm sorry to hear that! I've heard of that happening occasionally. Hopefully it still functions, just need to keep a closer eye on the oil level hopefully that's all that it is. Do you get any oil into your air lines at all? I know that usually happens even when the oil isn't leaking.
@@DIYDad1 negative, just simply comes out of the breather, curious to know if maybe the pores in the breather arent open enough
@@NoDayz0ff huh, I haven't taken it apart far enough to see what could be causing that. Hopefully it's not too bad. Sorry I have no idea lol.
Approximately how many oz. Of oil do you need to fill it up after changing the oil. I can't see my bubble anymore
I'll check the exact amount in the manual, they should have the manual in their website for this you can download in a pdf. I believe it's 5.6 ounces. www.manualslib.com/manual/65045/Central-Pneumatic-67847.html?page=15#manual
Call harbor freight replacement parts department. You can probably get a new one for it. Also to all harbor freight shoppers including me. Go on the websites or app and look for recalls on items that you have bought from there.
@@DIYDad1I wish that you didnt have to download the manuals. You should be able to just look at it on the site or app. Then have a option to download if you wanted to. But it is what it is.
@@WUBBA_LUBBA_DUB_DUB. Yeah, pretty typical for most manufacturers now, save to pdf somewhere on a ftp site or something lol.
I see that you are using a 3/8 hose, I have the same compressor but I could not get the air that I needed for my impact gun to work, MY GUN CALLS FOR 90 PSI-But I was only getting about 60 or 65 lbs-So I took off all of the air fittings from all of my air tools and drilled them out-The stock fitting are only about a 1/4 of an inch ID, Now I have full air power to everything-Now you can buy bigger fitting but why do that when you can just drill out the ones that you have on hand, My gun would not brake a Crank bolt lose, But after I did what I did zipped it right off
I've been using the Milton high flow fittings I found on Amazon that helped dramatically. I might have to make a video on that some time and setting up your air compressor to maximize it. But you're right the stock fittings are very restricted, especially if you want to use high cfm tools like an air impact. Of course there are losses through the whole system and the resistance of the hose itself, even the length of the hose makes a difference, you gotta look at the working psi at the business end and not rely on the regulator entirely. Setting a regulator to 90 at the tank might only get you 60 or 70 psi on a 50 foot hose. So I usually crank it to about 110 on the regulator and it gets me to where I need to be at the end of the hose. Thanks for watching and commenting! Glad you found this video helpful!
Shouldnt need to change that oil but every other year if your using synthetic.
That's about as often as I ever do it now, just when it was new I did it a few more times as things were wearing in. Thanks for watching and commenting!
No need to change the oil 5 times. I've had my compressor on the dirty dusty farm for many years and never have changed it even once.
Probably overkill for sure lol. All the reviews I’ve read said to at least change it a couple of times when brand new just to remove those metal flakes from the motor manufacturing. Just helps to keep the piston from getting scored prematurely. Still using it to this day and I’ve had this thing for probably 5 years now and it’s still going strong!
Does it need it?? Nah. Will it help it perform a little bit better for maybe a bit longer??? Possibly. Will anyone buying a tool from harbor freight care?? Nah
Are you running synthetic oil in it?
@@isaiahspinney6113 I bought mine used on market place for $20 bucks with broken reed valves.$8 later and its working like new, changed the oil 2 times cuz it looked old n dark. On engines that haven't had oil change in awhile a 2nd flush cant hurt .
Replace the 1/4 compressor air hose fittings with 3/8 and feel twice the power muwahahaha
Honestly thought about it lol. There are some good high flow fittings that I put on here and the cfm went way up compared to the standard 1/4. The ones made by Milton are the best. Milton S-760 1/4" MNPT V Style High Flow Plug - Pack of 2 a.co/d/0wpZsWK
@@Biophyswiz and not only that but shorter hoses can help too! Going from say 100 feet or 50 feet down to 25 feet really helps lessen the amount of air resistance. I might try a short 1/2" 25 foot hose and see how that performs compared to my 50 foot 3/8.
