Damn
I found another one https://www.ebay.com/itm/New-Makita-HM1304B-35-lb-Demolition-Hammer-Includes-Carrying-Case-with-Wheels/162901194803?epid=78307254&hash=item25edaaf833:g:tJwAAOSw1LRZrz6R
Some of the other HM1304B on ebay match the parts list
So I have 2 fake Makita jackhammers with no way to get parts
