Hi, went to use my 'k' series karcher pressure washer and had difficulty connecting/disconnecting the lance fittings.
Solution use a 8.5mm drill bit to enlarge the blue or yellow inserts at the end of fittings. This can be done by hand with a sharp drill. replace 'o' ring underneath the insert.
All goes back together and now works like new, no water leaks. Good luck.
