Where is the serial number on a hitachi DV18DGL combi drill

Yes they do, but did you keep a copy of them?

Where is the DEWALT® serial number on my cordless tool?

Mar 8, 2017 - Traditionally, serial numbers for DEWALT cordless tools have been located on the ... Just below the QR code is the serial number for this drill.

Did the receipt have it listed?

Bosch did not make a 'combi boxer' or a model #350-2
Unfortunately, you probably have a cheap Japanese drill sold as a Bosch with a fake Bosch label, we see plenty of them come through.

You can find an Authorized Service Center near you on Hitachi's website (www.hitachipowertools.com) to see if they have a switch to sell you. Another optioin is sites like www.ereplacementparts.com where ou can do a search on your model number and find your switch. They do have your switch available (PN 333640) for $38.70 +S/H.

I have just had a similar issue I left the drill unused for a period and when i placed it in the charger the charger showed the battery as charged after about 15 secondseconds.

Following a internet search i found a site that suggested for a imlar problem with a camera jump starting the low battery with a 9 v battery. I had a spare from the drill which was fully charged so placed a contact from + to + and - to - and held for about 2 mins. I then placed the battery back in the charger and it started charging. Running the battery down as we speak to recharge again well worth a try. If you dont have a spare maybe the 9 v would work

It sounds like the switch is bad. Not uncommon to loose either forward or reverse when they fail. Here is a link for buying a new switch part #322994

I Have 3 hitachi cordless and they all do the same .
Unrealible

No, the charger has its own serial number, the only serial is on the tool itself.

There are 2 small latches, one on each side of the battery.  You must push these in while pulling down on the battery to remove it.

 

Here is a link to the user manual if you need more help.  It provides an illustration of the method on pg 14.

Give me the exact model number and I will find you a schematic to use before you start this. It is not really that hard. Let me know and I will come up with it.
