If you have rota-lock valves, you need to bypass system low pressure alarm, connect your manifold gauges, close suction valve until suction pressure is slightly above 0 bar gauge and put charging hose in oil can. When hose is vented of air, close more suction valve to lower pressure below 0 bar and oil will be sucked from can in to compressor crankcase. Take care that hose is always submerged in oil to avoid sucking of air. When oil is enough close manifold and open slowly suction rota-lock to full open to avoid oil hammering.

Take care to not overheat compressor by doing this for extended period of time..

on some comps there is a valve on the sump under the oil pump if ther is then you can pump oil into the comp its a 3/8 valve so you may need a reducer 3/8 f 1/4 m

Or you can use a manual oil pump to push it in via the low pressure side.
