General Mirror Use Tips:
● Use clean and pristine mirror only. No scratches, pits or cracks.
● Needles tips caught in scratches, pits or cracks will not meet planarity
requirements.
● Set tool rings and eject caps gently on mirror surface.
● Avoid sliding on the mirror surface at all times, especially with needles inserted.
● Insert needles and planarize them by gravity only.
● Excessive pushing on needles will pit and scratch mirror as well as break needle
tips.
● Tighten set screws very gently while needles are in contact with mirror.
● Fully tighten set screws after piston is lifted off mirror.
