NOTE

Use a sharp instrument and cut two scribe lines on the M15 elevation quadrant. Use a straight

edge when possible to be sure the lines are even with each other.

Scribe one line (9) from the range quadrant mounting bracket pivot stud (10) to the front side of the M15

elevation quadrant (8).

Scribe the second line (11) from the cross-level knob (5) to the side of the M15 elevation quadrant (8).

Paint these scribe lines (9 and 11) with a paint that contrasts with the color of the M15 elevation

quadrant (8), so that they can be easily seen.

Wipe off the excess paint and let it dry.
