If you ordered the kit directly from HKX as a hammer kit then it will be no problem. They are one the best Aux plumbing kit manufactures I have ever used! I have built my one kits and would never ever do that again after using HKX products. Most important is to remember to install pressure reliefs in your control valve and to flow the machine and set to your hammer. Also after the couple hours of operation, go and tighten every single line you installed. Trust me, do it. Their instructions are real good and they have excellent tech support, so I say go for it!
