Input:
Question: what is the air demand (scfm)
Document: A few drops of oil every time I added a new roll of nails seemed to be about right. Unlike a framing nailer I reviewed recently there don't seem to be any lubrication-related problems.Air pressure need also seems consistent. It seemed to run best at about 85 PSI, i.e. varying between 80 and 90.
works great and very ligh, this tool made working on the roof a breeze feels solid and durable too great deal
two roofs so far and no misfires very professional love it its light weight and fast the only roofing nailer to buy
not much to say,great tool,durable and nice to handle,i did shoot half a million nails in a season with it without any problems ,i think that says a lot about the quality of this nailer.
i lose money every day and returning takes time. i had trust for hitachi but something somewhere has gone terribly wrong. every time i go and replace my gun i choose different store but it doesnt help. 4 guns returned thus far and people at local lowes have started to look at me like there was a problem in me. if you buy one make sure you buy an hell of a warranty with it.
i have returned 4 hitachi roofingnailers in past 2 months and im on my way to return my 5th. repeating problem is that gun drives crooked nails or skips them right after taken out of the box. and it hapenes with every 3rd or so nail. my last hitachi lasted for 1,5 years until tools body wore thin and i cut myself with an sharp edge but never failed me. last 5 have been total dissapointment.
friends that are roofers only use this gun. I am a diy and it worked grate for me. Why not have the best for cheep!
did not recall having getting 5 nail at a time. what a disapointment. we own a hitachi framing nail gun, a hitachi jack hammer, a hitachi twin tank compressor. a hitachi miter saw. so we decide to get a hitachi roofing nail gun when my bostitch roofing nail gun fail. big mistake. should have buy a milwaukee instead, or bostitch (does not last but dependable when working). my advise, don't trust the brand, or buy online.
big surprice, nail gun is not sequencial trigger. have to order seperate trigger part. takes a week to get the part tru hitachi. 1st job site use, use 1 1/4" coil roofing nail brand new box. could not get the nail to come out each shot. takes about 7 to 15 shot for 5 nail to comes out per shingle. move the chamber adjustment level to all position, check and lube nail moving mechanism. replace coil nail after coil nail.
Would not hesitate to recommend this for anyone. Just wish it has a dept gauge so I don't have to make adjustment at the compressor.
