PRECAUTIONS WHEN USING THE INDICATOR
• Avoid dropping the Indicator.
• Avoid extreme temperatures, direct sunlight or
below freezing for extended periods.
• Do not allow the indicator to get wet.
• Avoid shocks to the contact point and spindle. Do
not apply any radial force to the spindle.
• If the indicator is stem-mounted, protect the
indicator from being struck or bumped to prevent
stem/case mechanical alignment damage.
• Do not over-tighten the mounting mechanism
and use clamp mounting rather then set screws, if
possible, to prevent damage to the spindle.
• Frequently clean the spindle using 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 any type of lubricant to the spindle and
do not use solvents.
• Avoid any disassembly or modification of the indicator.
• Avoid using anything that might damage the buttons
when pressing the buttons.
• Use the appropriate gage stand or indicator holder
for the job intended.
