How to access neutral safety switch L3800?

[Rail Dawg]

On the L3800 to the left of the brake pedals is a steel cover for the neutral safety switch. It's part of the linkage for the HST and I need to access that area so I can clean it out. My 3800 won't start sometimes and I think it's because the linkage sticks.

Has anyone done this? Is it pretty straight-forward?

Thanks!
