The following is similar to marking your Dec and RA axis with tape.
Put a piece of tape across a convenient location where the mount base and pier move in azimuth.
Draw line across junction.
Cut tape along junction between the mount side from the pier side
Put a thin piece of tape on both azimuth knobs.
Loosen one azimuth knob 2 turns
Tighten the other azimuth knob 2 turns.
Which way did the line on mount base piece of tape move in azimuth as seen from overhead.
Reverse the 2 turns to move mount back to original position.
