Help with new purchase

I was gifted a Hatsan Flash QE rifle recently.
I am not sure that as old as I am I will be able to hold it still to meet it's accuracy.
However, This rifle requires a charging tank as I understand it to pre charge the rifle.
Just what all do I need to buy to charge it.
Maybe someone could direct me to a UTube video?
 
The video is a good comment, I think. I was actually gifted a Benjamin pump by my kids and bought my own first PCP, a Marauder pistol. I like the pump and still have it but I think the inexpensive chinese had pumps are definitely the way to go if you want a hand pump. I bought my chinese pump when I got my Avenger since the Benjamin only goes to 3000 psi and the Avenger can go to 300 bar - over 4,000 psi. My cheaper pump cost about $60 and I got it from Amazon. Later I added a Yong Heng and then a used SCBA tank.

Even though I have a bunch of other ways to fill my guns and that is what I normally use, I still like having a couple hand pumps around. If I had stayed with just my Prod I probably would not have purchased the other pieces. A hand pump is very portable but it does take some effort to pump up a gun. Not a bad thing but it is different when the gun needs several hundred pump strokes to get refilled versus less than 50. But if the YH breaks, I will definitely be hand pumping again until I get it fixed or replaced.
 
After reading and such I decided to just bite the bullet and buy one of those mini compressors.
I am a long distance from a paintball or scuba shop and I don't want to be bothered with certifications on the tanks and such.
Money wise I spent a little extra on this.

Mini compressor means happiness on this hobbie.
