I have ,had SP250PM255PM300And now I just got the new pm 360. Still have the SP250 and the PM255. I have always liked them to run a little higher V than the recommended settings. I had a small job mounting a new hitch to a 7 scd40 bumper. So since Im used to a little higher V I set at 3/8 boy does it have power! First pull on test material I blew a hole in it. Set it to 5/6 and 👍 think Im going to like the new toy I mean TOOL.
