Average Reviews:
(More customer reviews)I purchased one of these units and was very pleased for about 3 months. The unit ran great and was very quiet for a compressor due to the induction motor. Running it indoors you can actually talk over top when its running and hear the other person. At 3 months the unit stopped working and would only hum without kicking on. After replacing with a new unit I was ok for about 3 weeks and the same problem happened. The issue is th e oil level. Hitachi supplies a small bottle of 5w-50 oil and the instructions are to fill on a level surface to a point between the notch on the dip stick. The first time I over filled slightly using about 4/5 of the oil supplied. on the second unit I filled to the required level or about 2/3 of the oil supplied. Both units eventually seized. After speaking with a customer service I found out the supplied oil is premeasured and ALL THE OIL SHOULD BE ADDED. I found Hitachi to have very good customer service, the first unit was replaced and the second serviced at no cost. My opinion is this is a very good unit with a small design flaw on the oil pickup system and instructions which should tell you to add all the oil. Also note, when they say don't operate at more than 10 degrees angle, they mean it. The oil will not get to the crank and the unit will seize. This unit is very small, very portable, extremely quiet unit and supplies 4.cfm @ 90psi all of which is a great combina tion. I would have given 5 stars except for the lost time and effort of not properly addressing the oil issue for this unit. At the end of the day I purchased a dewalt D55146 oil free unit for a backup as jobsite reliability is key for me. I hope the Dewalt performs better over the long run.
