Worth watching a youtube video or two on loading, attaching, and de-attaching grease guns if you've never had the pleasure to using them before, there are a couple of nuances.

This is the flexible bit I'm talking about:

Thanks Andy,
Just got back from toolstation with the gun, but didn't get the flexible hose, looks like I'll be going back!

One question, how do you grease your ballscrews? There is no nipple I can see...
