Title: 2 pathetic things
Product review: What would have been a great compressor (aside from regulator placement) is spoilt for me by 2 things: 1) for about $1.50 a muffler could have been put on to reduce noise by 25-30 dB (to less than 1/4?) and 2) the unloader valve that is supposed to relieve pressure from the cylinder head after the compressor cycles off is poorly designed. When it fails, the motor has to try & start with the head under pressure, which mostly it cannot do. This is also likely to burn out the motor. This same thing may also be the cause of all the poor starting in cold weather etc. I have a simple fix. If you (or Hitachi Co.) want it, email paul@pthompson.com I have since bought 2 Makita 3.5hp compressors, and now having fixed this I shall probably sell it.
Would you say this review depicts the product in a flattering or unflattering light?
