Worked at a tool rental store while attending college and learned some tricks from the old-timers. To extend the life of flexible blades such as the one used on floor tile removers, use a second shorter blade on top of the longer blade (double blades). The shorter backup blade tends to absorb the extra force making the longer blade last longer before breaking. The length of the shorter backup blade is trial and error, however start with about 3/4 to one inch back from longer. The wide chipper bits tends to break also. The wider the bit, faster to break. No matter what size hammer. Has to do with the bit hitting the stop on the forward motion. Some older chipper hammers that had rubber or spring loaded bit stopper would prevent wide chipper from breaking so fast. Good luck

be sure your belts are tight enough .check if your pump is not jammed.try to turn it by hand with the power off.

I just looked a the owners manual, did not see a reset, try taking the plastic cover off and see it the motor has a button on it to reset the motor, the motor may be damaged also, always try to use a direct connection to the wall outlet for power, Hitachi air compressors dont like extension cords.

hitachi's use 5w50 synthetic oil

by jammed I take it you mean a nail has jammed the driver? If that is the case there is really no easy to unjam it. But unplug the air hose and turn tool upside down and wearing safety glasses and gloves you can try and take a punch smaller than the nose piece and try hitting the driver to unjam nail. If it is another problem please let me know and I will try and help more.. Sometimes we used to have to remove the nose and heat and it goes on but hopefully it is not that bad

Just hook the black (gnd) wire to one screw and the white (signal) wire to the other. You should crimp ring connectors on the end of the wires for a good connection. The red (+5v) wire is unused.

I buy most of my parts from www.toolpartsdirect.com. The headvalve is the only part that wears in the head. It will leak when the rubber/vinyl seat material begins to crack(new models use rubber). If the head valve looks ok with no cracks then no problem in head. If you are having problems with the gun please post again describing issue. Good luck

Hi,
There is a relief that allows the pressure to come off of the cylinder head to enable easier starting when it restarts. Sounds like that relief is doing what it should but the check valve between the compressor and tank is bad.
Somewhere in the line from the compressor to the tank there is a check valve and that is no holding. Probably has dirt under the seat.

Orings, they have to be replaced every few years. Warranty does not cover them.

Any Hitachi service centre should stock them. Or find your model on Ebay:

Hope this helps!

Thanks

I know of only one company that has a complete kit but they are located in the Cincinnati, OH area. They would need to know if this is a coil nailer/roofing nailer and some other info but these kits unless you can find an air tool repair center in your area are complete, I have used them for 6 years and they should take care of your problem. Their site if you want to view it is Nailgundepot.com and they have another link. Let me know if you need more assistance. The kit lists for around 12.00

Go to Hitachipowertools.com and type in your model number and you can download a manual for this tool

Something like this?

First off more information is needed. How old is it? Do you use oil when you use it? Most likely it needs a rebuild kit.

This is the US-Hitachi service center locater internet address. Just enter your zip code and radius and it will return a listing of service centers close to you. If this answers your question please mark it as solved and you can leave feedback on me.
