I purchased a rebuilt, maverick hammer, but the coupler does not fit my Volvo Ec150. I am looking for a well S1 attachment weld on coupler if anyone knows where to get it I would appreciate it. Also, the Maverick was rebuilt and spent $7000 and it heats up every three hours, if anyone knows how to adjust those pressure for nitrogen, please let me know, trying to get hammer and attachment set up for Volvo connection. Anyone have experience with this type of stuff.
