New Holland 1033 stackliner problems

I recently purchased a 1033. In preparation for the season I’ve noticed a couple issues. 1. The load arm goes all the way to the ground. How can I adjust this to ride a few inches off the ground? 2. The pickup chain (on the load arm) won’t run continuously unless you HOLD the lever forward. How do I fix this? Thanks in advance
