Need manual

Check for blockages just inside the inlet, check for non return valves for sticking or not opening fully. Impellers often have a box channel that the liquid travels down when spun, check these for obstruction. Only further thing, the pump normally has to be primed and be FULL of liquid. Any air inside the pump will reduce flow.

For the manual

make model manual

or check the manufacturer's website.

I used to own a watermill and used a lot of water supplied by a jet pump.

How do i operate it?

Go to the Mastercool web site:
Pick out your model number and then click on "instructions" to download a manual. The most important thing is to change the oil frequently. This unit is used in HVAC to draw a vacuum on an evacuated AC system after repairs were made to insure it is free of any condensables.
