How to repair fix a Hikoki, Hitachi, Metabo HPT NR1890DC nail gun that won't fire.

Another Hikoki gun NR1890DC nail gun is in for repair. Another new problem was diagnosed and repaired.
This is a new one for me, havnet seen this fault before, so anyone having a problem like this, here is the solution.
This problem was the magnet on top of the contact probe. I only dismantled the gun yo find the fault. But if you have this problem, there is no need to dismantle. You can easily replace or repair the magnet with dismantling the gun.
If your gun is not firing like this.
Turns on, will go into service mode, is not showing any fault light, but will do nothing else. Then the problem will be one of only a few things.
This magnet on top of the probe.
The trigger switch.
Or the pickup sencor itself on the top.

    Ha, that's handy. No need to ring on Monday to let you it's ready then. Yea, seems every one is onenthe same page with the hikoki guns. Good power, cheap to run and you get your moneys worth. If only had 3 so for that were beyond repair. But customers didn't mind as they had so much work done.

    Enjoyable to watch you diagnose this for the first time. Love your customer service ethos too - breaking down a new machine so you have spares on hand. I wish all shops did this rather than push you to dispose and buy new.

    Thank you, sir, for sharing your hard earned wisdom and knowledge. You have saved me well over $1000 US since I found your channel. I just opened my $576 metabo cordless that I thought was toast to find a blown fuse.😊 Before that you taught me how to repressurize it when it quit sinking nails all the way. That's just one tool the many your videos have helped me keep on the job, not in the trash. I too get great pleasure out bringing tools back to life. Bless you from Georgia USA.

    I’m a carpenter and I have this Hitachi cordless nailer as well as the gas Paslode framer. Both great guns but I reach for my Paslode 9 times out of 10 because of the weight difference. Plus I actually enjoy servicing the paslode. Buying the gas is just the price you pay to be light weight & hoseless.

    @deandohertygreaser used a hand pump and made an adapter for the schrader valve with a gauge. Tried to pump it to 90 but lost a touch of air everytime I disconnected and I think the valve itself made line pressure higher than tank pressure. I put 110 on it and it works fine now, it isn't perfect especially 2" nails into hardwoods but for everything else it still works. You're much better with these things than I am or ever could hope to be so I'm sure you'd find the golden ticket

    Nice repair! I would have dignosted this one at the start as being an electrical problem as it didnt even show any sign of life at all. But well worth taking it all apart and finding the magnet to be the problem. Do you ever get any of the Makita DBN600 brad nailers for repair ? Those are spring based and a bit more complex then these Hikoki nailers. We don't get to see a lot of these Hikoki in the Netherlands it's mostly Senco nailguns here, the old ones worked with a closed nitrogen driver assembly like the Milwaukee, but the new ones have the same working principle as these Hikoki nailguns on air presure.

    Yea, I see that. They were around showing them of a few weeks back. But spare parts for them are only becoming available now. The Makita isn't spring based it also uses compressed air. But it built like the ryobi gun. Basicly uses a piston and pin built inside a large piston for compression. Not a very good gun, no one like them and they can be a torture to work on.

    I have this gun. Yesterday after a shot with a 90mm nail, there was a click, and it stopped working. Both yellow lights are blinking, and it doesn't allow me to enter maintenance mode. It neither helps to swap batteries. I recently refilled the gun with air. It's 2 years old and has run maybe 10-15 000 nails.

    It dosent. It's a sealed system. The air never gets out. It is simply compressing the same air each time with the piston.
