I just did my 50 hour service on my kioti 2410. I'm having some trouble with my power steering and loader joystick. The power steering is stiff, although I worked it a bit and it loosened up a little. And the front end loader joystick is very sloppy. I was wondering if there could be some air in the system? Fluid level is good. Is there somewhere to bleed the air out? Any suggestions would be appreciated.
