Guidelines for Indicator Care
1. Avoid dropping the indicator.
2. Avoid extreme temperatures and direct sunlight for extended periods.
3. Avoid contact with liquids and dusty environments.
4. Avoid shocks to the contact point and spindle.
5. Do not apply radial force to the spindle.
6. If the indicator is stem-mounted, protect it from being hit or bumped to avoid
stem/case mechanical alignment damage.
7. Do not over-tighten the mounting mechanism. If possible, use clamp mounting
rather than set screws to prevent damage to the spindle.
8. Clean the spindle frequently with a dry cloth or a chamois to prevent sluggish
or sticky movement. Isopropyl alcohol may be used to remove gummy deposits
on metallic parts. Do not apply lubricant to the spindle or use solvents.
9. Do not disassemble or modify the indicator.
