Make sure your beer is cold?
It's a pretty straight forward installation. Just make sure the inside knob is mounted to a secure mount, not to plastic.
Also mke sure the cable does not get too close to the exhaust manifold and no sharp bends.
Be careful opening your beer you do not spill any.
That's about all.
Did you get the PosiLok brand cable? I have it and it never fails three years in.
