For the record

Thank you very much Warren 

The red cap is a dedicated oil filling point.  Depending which batch, the cap has OIL written on it in some cases.

The two bottles are full of vacuum pump oil.  They are supplied by the pump manufacturer hence a slight colour difference to the oil we retail seperately, however both oils meet the necessary standards.

Hello, I'm ready to operate my big EC vac pump for the first time. I'm a bit confused about what to do with the red cap. What's its role ? I understood I've first to remove the big black fitting cap to poor some pump oil in. But what to do with the small red cap located near the botttom of the handle ?
