Just bought one. How much oil is needed to run this compressor. Came with no instructions....

Asked by: Anonymous
See manual. Page #16, owner’s manual: NOTE: Avoid refilling with too much oil. Ensure that the level of the oil does not exceed the maximum reference level on the dipstick. The recommended amount of oil for refilling is 7.2 oz. (204 g).

Customer Reviews

5-Gal. Mini Wheelbarrow Air Compressor-DISCONTINUED is rated 3.3 out of 5 by 25.
Rated 5 out of 5 by from READ THE INSTRUCTIONS FIRST! I've seen some reviews complaining about this compressor not starting and tripping breakers. Heres some clues. This compressor, or any other, WILL NOT START on low voltage. The usual culprit is cheap, small gage extension cords and breakers too small to supply the motor. Use at least a 12 gage cord for lengths up to 100 foot and 10 gage after that. In cold weather I use 40w5 synthetic oil instead of 50w5. I have used mine for two years and never had the first failure. If you don't know how to operate it READ THE BOOK. Thats why the send one. If yours is lost, Google it. It doesn't take that much extra time.

Rated 5 out of 5 by from Best in catagory Purchased this unit to replace a recently purchased "tan brand" that came with a bad limit switch and it has proven itself to be the right choice, but you'll want to make sure you know exactly what you'll be using it for before pulling the trigger. If you are mainly inflating basketballs and running the occasional 18g pinner, than this is probably more compressor than you need. It is a large unit and the side by side hotdogs and wheel make it awkward to store. The wheelbarrow setup makes it very easy to manuver (no need to put it in a cart) but it doesn't offer any onboard storage either. If you plan on runnig sprayers or sanders, this one won't do it. At 4.6 cfm, it just doesn't have the grunt and the 5 gallon tanks will always be playing catchup with air hungry tools. If, however, you are a carpenter who works alone or a small roofing crew, this is your rig. This unit will go from 0 to 145 psi in around a minute and will easily keep up with multiple pinners or roofers. Have not had two framing guns on it at the same time, but I'm confident it would handle it. The controlls are well layed out and robust. There is a pin-pull valve up top and a 1/4 turn petcock on bottom and you can lean the unit over while draining to get out any water without bumping anything. For those used to oiless (if that's possible), it is extremely quiet. There is a motorcycle style site glass on the crackcase which allows you to check level and condition of the oil without having to pull the dipstick and the breaker reset is easy to get to without burning yourself. For those who complain about breakers, keep in mind that any tool pulling 13.5A @ startup is going to pop a weak 15A, especially if it's cold. I put a heating pad under mine for about 20minutes on cold mornings and it fires rite up. A little prep seems a small price to pay for durability & comfort. I wouldn't run this (or any other compressor for that matter) off an extension, but the attached power cord is 10g and comes with a velcro keeper. As far as I'm concerned,this is yet another quality piece of kit from Ridgid.

Rated 5 out of 5 by from I've had mine for over 2 years now. Works great. I've had the product over 2 years now so I thought since I've had some real experience with it, I'd write my thoughts. I've used the product to: --------------------------- - Power a finish nailer and install crown molding and base shoe / quarter round - Power a framing nailer and frame a fence and install slats - Power a roofing coil nailer and roof my house I also use it for small chores like air up tires with the inflation adapter and blow out my sprinkler system at the beginning of winter. Now for my thoughts: ------------------------- I bought the product when I was going to get a cheap porter set for the baseboards, but i thought it seemed more useful with its advertised ability to power roofing and framing nailers, but at the time I only had a finish nailer. It of course worked great for that job, no complaints. Next project was the fence, for which I purchased a framing nailer. This was awesome. A thoughtful investment finally paid off. The unit put out enough power and I never had an issue with having to re-hammer nails which did not have enough pressure to drive fully. Next the roofing. Aside from biting off more than I could chew and my back telling me about it for the next 4 weeks, the compressor never had a hiccup. Advertisement says it could run 2 roof nailers but I never used more than 1. However, it would refill the tank after about 15-25 nails, running for probably 30 seconds to refill so I see it most likely could handle 2 roof nailers simultaneously, unless you're pros going mach10 - in which case you wouldn't be looking at this unit anyway. For small chores like filling tires its easy and quick to set up which is nice. Definitely faster than taking your dolly or car up to the gas station and paying a buck for air. The pressure adjustment knob is easy to use and the gauges are obvious about how much pressure you'll be putting out. For blowing out my sprinkler system it's a bit underweight; it simply doesn't have the capacity to make the job quick but it does get it done. I usually have to let the tank fill up 5-7 times per zone on my sprinkler system so the entire project takes about 1-2 hours. Synopsis: ----------- I think for the price it's a great little home use and handyman quality air compressor. I've seen the complaints about cold use, I'm a little surprised any electric powered compressors work well in the cold. I'd imagine gas would be the best choice there. But I live in Denver and I haven't had a problem yet. It could be a combo of cold and humidity that's a problem. I'm impressed that with intermittent use over 2+ years now I haven't had a problem, especially with a move from Texas to Denver. That change in humidity has caused a few problems in my other tools and personal property. I'm very satisfied with the air compressor and I find it's compact size, mobility and array of usefulness perfect for my needs. Hope the review helps you find what you need.

Rated 5 out of 5 by from great product! I don't understand the reviews that complain about cold starts. Plugged in to a 20 amp breaker without extension cords this thing ran without a problem in the 30 degree northwest winter. I just yesterday sprayed a truck with a husky hvlp pro and it kept up. It will run two framing guns without hesitation. This is a fabulous compressor for the money unless you don't know what your doing or have very bad luck!

Rated 4 out of 5 by from Mini Wheelbarrow Air Compressor I really like the compressor. I put it through a lot of abuse at the worksites. I run framing and roofing guns off of it. The only down side to the compressor is, in cold weather its startes up harder. What I mean by that is , it seams to need more amps. to start

Rated 4 out of 5 by from Can't go wrong with this produce This is the second one of these we have purchased for use at our warehouse. Both get used every day for 4-6 hours with pneumatic engraving tools. One is over a year old. No issues at all. Great product for the price.

Rated 4 out of 5 by from Yeah... So it won't run if the oil is frozen. Show me a 13.5 amp oil bath model that will... This is the reason they make block heaters. Put a 2x under the oilpan (aluminum, magnets won't hold) stick a block heater on it and deal. Or buy one of the disposable Teflon ring oil-less ones. If they hold up twice as well as the frying pans you might get a few years of use out of them. I'll take the oil compressors and the minor inconvenience of keeping them warm.
