## Questions & Answers

**Q: Do you have instructions on how to use this?**
A: Here's a video with step by step instructions.    This was produced by the Metabo HPT Service Department.  https://www.youtube.com/watch?v=ii_L82J8WbU

**Q: What pressure for the 18g hpt finishing gun (nt1850de)?**
A: The pressure for NT1850DE is 50.7 psi. It would be best if you used regulator 371209 instead of 371208.  Set your compressor @ 110psi.  The regulator should set the pressure automatically.  The regulator 371208 is set at 72.5 psi which is incorrect for your tool model.

**Q: Is this the correct guage for my Hitachi 15 Gauge angled finish nailer ?**
A: Not sure exactly the Hitachi model you are referring to, but if your nailer model is NT1865DMA, you will need to use the 371210 regulator.

**Q: Is this the regulator for refilling the metabo hpt cordless 18v multivolt™ straight finish nailer model nt1865dmst ?**
A: Yes, it is. I have the Hikoki 16Ga NT1865 DBSL. It's the same nailer as your's, just another model number for Europe.
