How do I switch the hydraulic control pattern (ISO to SAE, etc.) on a John Deere excavator?

[James R.]

If I accidentally switch the pattern mid-shift, what is the most immediate operational change I experience?

What is the key safety precaution I should immediately take?

you'll feel it right away-the controls will feel totally backward! best move is to stop the machine immediately, lock it out, and double-check the pattern switch before operating again.
