IMPORTANT:
It is the responsibility of the user to ensure proper
maintenance of the Self-Leveling Cross-Line Laser. Conduct
periodic test measurements to ensure the instrument is measuring

instrument has been exposed to extreme temperatures or
moisture. Keep the Self-Leveling Cross-Line Laser optic lens clean
and inspect for damage.
