With that tension clamp, it should work flawlessly both ways irregardless if diablo use or not. Star5 15 may be right possibly a bearing missing, anyways the slipping should not occur.If it is new, then there should not be a build up as yet, or even need to be cleaned as yet.
Somethig is wrong, he should send the tension head back to the company since it was just purchased.
