This 1-1/2 foot cube gas compressor fits in the trunk of a midsize vehicle. This is the only gas power compressor that I have worked with that a single average size person can move (alone). The engine optimizes fuel efficiency by automatically slowing to an ideal speed when the air tanks are full. The engine, even while operating faster to fill the air tanks, is relatively quiet allowing a normal conversation a few feet away. It is quieter than the pancake compressors I have used. Each air tank has a separate moisture drain valve to keep the tanks from rusting on the inside. * The air regulator comes with two 1/4" female NPT thread connections. Since I could not remove the stripped hex plug, I used the air gage connection to add a tee.

The unloading elbow was snapped off from the check valve assy. Makita has a problem in the packing of these compressor's which leaves the valve exposed to being crushed inside the container.The valve is on the side and all it takes is a slight bump and it's sheared off.If you need to put the compressor into service right away, I suggest buying local or unfortunately another mfg.The compressor is quiet, and seems to run ok, I have only done the initial start up though.Seems to be a great little compressor. I'm going to use an easy out to remove the broken thread/stud from inside the valve and just buy the elbow locally(I hope) You can see many other posts on the internet regarding this same problem.(supervisor)The compressor has been in service now for around 8mo.I did solder a new elbow onto a lower area of the check valve which works out better when the compressor rolls on its side. Received Item, but can't use it yet. - BUT, because of the poor packaging, and the probable mishandling by UPS, the Unloading Valve* was broken off inside the main Check Valve.* Damaged Goods - The black plastic engine housing was cracked but remained in place, the air/condensation release valve at the base of the tank was broken off at the tank !?#%#! After a little hand work I removed what remained of the fitting, reversed and reinstalled the valve. After repairs (seems odd to repair a brand new machine) it seems to run great, no oil or air leaks. Arrived damaged - After opening the cardboard box that was obviously crushed, I found the plastic motor cover broked and the brass unloading elbow broken-off in the check valve* attached to the side of the tank.* Another Damaged compressor - both the shroud and the unloading valve* were broken (see other reviews) with no apparent damage to the shipping box.* Makita MAC700 -nice little compressor - I almost didn't order this compressor after reading all the reviews about shipping damage, but mine arrived in perfect shape. My old pancake compressor finally died. It is resonably portable and very very quiet for a compressor. The drain valve at the bottom makes quick work of draining the tank at the end of the day. Great little compressor - Be sure to fill with oil and install the air filter before starting. It required drilling out the check valve, retapping the threads, buying an equivalent part at the hardware store, and reinstalling. Serious PITA, but cost was minimal and repair works fine. All in all, a great little compressor, and the best choice if noise is a concern. *Great compressor, but check the box thouroughly before signing for delivery!* - After working with a friend's older version of this compressor for the last eight months, I decided to splurge and get my own. If this compressor is anything like the older model, it's going to last forever. It looks like someone must've dropped it, and from a pretty good height! One of the legs was bent about 2 inches, so the compressor would rock when set down. Fortunately, the compressor itself (external tubes and gauges and whatnot) are all fine. It's annoying, but I don't want to go through the exchange process and be without air for another two weeks. The startup process is fairly simple. There are two plastic plugs on the compressor that need to come out. One covers the oil filler, and one covers the air intake port. You replace the plug on the air intake port (topmost plug) with the included air filter, and you replace the oil filler plug with the included oil cap. Then, open the air release valve at the very bottom of the air tank and run the compressor for 20 minutes. Check the oil level periodically, of course! On a related note, I also bought the Campbell Hausfeld MP520010AV air tool accessory kit to get me started.

Now I'm sure I'll be raped at the repair center as I spend >$100 to repair this $200 turd. Happy, but could be happier - The compressor is still fairly new and seems to provide excellent power for framing guns, finishing nailers, and hoppers. However, I am not incredibly impressed with this compressors ability to start. I realize during the cold winter mornings (not too cold in the San Francisco bay area), that some compressors require an empty tank to kick over, but this is getting a little ridiculous. On a 45 degree morning I don't even try to kick over the tank before making sure it is decompressed completely, and during the middle of the day I still have to, on a not-so-rare occasion, pull the pressure release valve. I have seen on another review that a Smart Start inlet filter can be purchased to cure this problem, but it's annoying that you need to buy new parts to cure problems on a new compressor. I guess having only one complaint for a power tool isn't too bad, but I'm sure there's a better compressor out there.
