Why did you pull it out??

Why would it needed a refresh at 62 hours? Or does it only have 62 hours since the refresh?

It wasn't running right so pulled out to refresh, now is surplus to requirements.

We weren't happy how it was running, as said hadn't owned it since new hence a refresh wasn't going to take any chances.
Other than being tested hasnt covered any hours since refresh and is now surplus to requirements.
