fill the reservoir, and open the slave if u can get clear hose on it and bleed it, using the end of the with your finger over it to not let it pull the fluid back put almost a full reservoir threw it. it should then have enough fluid threw that there should be no more air.

 

My 2 cents on bleeding the reservoir..... open the Clutch slave bleeder 1/2 to 3/4 a turn put a hose on the nipple and the other end of the hose in a glass Jar with fluid in it.

Fill Reservoir and pump clutch pedal Do Not let Reservoir get low while doing this.

this way makes it a 1 man job.
