The nailer was mistakenly oil for an extended period and subsequently damaged the piston and driver,: this is an "oil-less" gun
Simply dismantled the head and piston assy., removed the parts, cleaned vey well, greased the parts as required, re-assembled. Works like new. Applied magic marker writing to say "do not oil".

    Easy repair on a Dewalt 18 gauge nail gun that stopped working after a few uses.
    Your video's showed me how to repair the tool and the parts were very reasonably priced. I will use this service again and recommend it for all DIY repairs.
