Hitachi NR90AE

1 year 8 months ago #2342 by Tp7777

I have a NR90AE and I am having issues with piston sliding around in the cylinder. Put new o ring didn’t fix it. Swapped some o rings out in rear exhaust still continues to slide. Wondering if I need a thicker o ring or if cylinder is bad? Has issues flushing nails when nailing sheathing. Leaves nails up any answers? Fixes trying to trouble shoot thanks
