Learn how to repressurise your HiKOKI 2nd Generation 1st Fix Nailer alongside a service engineer from HiKOKI. Nick shows you:
1. How to enter maintenance mode
2. How to remove the rear cap and access the gas valve
3. Correct re-gassing procedure up to 9.1 bar
4. Tips to prevent gas leaks and extend tool life

A nailer with daily use would need re-aired every 3-6 months.

You can now order the re-gasing tool for a cordless inflator at Multifix. You'll need a different tool if you are using a compressor, explained in this article.
