Hitachi 5.5-HP 8-Gallon Gas Wheelbarrow Air Compressor w/ Honda Engine

I bought this new and with in 2 months the pump was leaking oil. Took it to repair center and now 2 months later Hitachi still has not sent replacement pump.

I work in the oilfield and needed a gas powered compressor that could handle an automatic grease gun for greasing industrial pumpjacks, airing up flat tires, and running a decent impact wrench.

I have never bought any Hitachi stuff before and I admit that I was a bit reluctant, because I like to go with names I have experience with.

After I bought the unit, I took off the rubber feet and the tires, and bolted it down to my truck bed. I have dragged that poor compressor through rain, mud, cold, heat- you name it. It starts on the first pull every time, and never fails.

I don't have to let off the trigger on my grease gun, and can empty 16oz. within 2 minutes. I have changed tires and aired them back up (after plugging them) in the field, miles back on dirt roads with no cell phone service.

On top of all that it is really fuel efficient and suprisingly quiet, even though that wasn't a major selling point for my needs.

This is hands-down the best tool and emergency device I have ever added to the collection of tools in my truck.

I can't remember how I did the job without it now.

Got mine as a scratch and dent. It is mounted to a deckover trailer and we just run the hoses we need to the site. Runs a long time on very little gas (I think it only holds a gallon, maybe two?).

I have been keeping up on the maintenance with the help of online websites and haven't had any trouble.

I bought this new, lifted the unit by the handles to move around a job site while it was turned off. Oil is leaking out of the pump air intake valve.

It happens every time I move it, so now it is low on pump oil. Hitachi has a bad design on this one. I should have bought another Emglo/Jenny wheelbarrow compressor.

We purchased two units and one had a major oil leak in the pump today. It sputtered and is not operational, even though it has hardly been used. Oil completely drained out of pump from leak. Not sure where the leak is, but will reinspect the second unit for similar issue.

I've never had a compressor break so fast. Stunned, as this was supposed to be rated well. It seemed to be running well until the oil leak.

These are absolutely the worst compressors I've ever owned We run a framing company based in Alberta Canada and have run Gennies for years, I was convinced by a local nail supplier to switch to Hitachi and let me tell you worst mistake ever. Do not purchase a gas powered Hitachi if you are going to use it in any commercial application as it will not last.

Their customer service is absurd and they will not resolve any warranty issues. The pumps leak, the pressure regulators leak, the throttle connection at carbs break. Maybe if you are a DIYer and use it sparingly it may be fine? Spend the money and buy a Gennie, Eagle, or better yet Quincy

I became self employed and buy two hitatchi gas compressors. I used to use rol-airs but bought hitatchi because they are cheaper than rol-air. Both compressors malfunctioned within the first year with the exact same issues.

They would run fine for 5-10 minutes and then they would suddenly make an EXTREMELY loud rattling noise and shut off. They also would spit oil at times and I had them both fixed under warranty but after a couple months it happened again to one of them (same issue).

I have the receipts but the one year warranty in over. What is going wrong here? These compressors are junk at best. Please help. What is the issue?
