Using my splitter for 2nd time today. Used it for just a few minutes yesterday, when I got it, to make sure it worked. Now, I go out, start it up , and theres very little pressure. I know this sounds stupid- but could whoever have assembled the splitter installed the hydraulic oil filter backwards? Look at the pic. Shouldnt the flow arrow be pointing AWAY from the tank TOWARD the piston? This would cause the lack of power , would it not. I'm freakin out! I hope the machine isnt damaged. Help!
