Foreword
Thank you for purchasing the Topcon RL-VH4DR/G2 Rotating Laser.
It is one the world’s most advanced lasers.
To quickly and effectively use the RL-VH4DR/G2, please read these brief instructions carefully, and
keep them in a convenient location for future reference.
Handling Precautions
Before starting work or operation, be sure to check that the system is functioning properly.
1. Vibration and Impact Protection
When transporting the instrument, provide protection to minimize risk of severe vibration or
impact. Severe vibration or impacts may affect beam accuracy.
2. Laser Scanning Interference
Particular reflective surfaces such as mirrors and some glass surfaces, can cause beam
reflection that in very rare circumstances can interfere with the laser scanning function. If this
should happen, simply change the location of the laser or cover the reflective surface.
3. Checking battery power.
Before operating, check remaining battery life.
4. Storing the instrument for long period
When storing the instrument for long period, remove the batteries.
5. Rotating Head
When sunlight, etc. enters the laser emitting window, laser beam output may temporarily
decrease. In such a case, prevent sunlight, etc. from entering by using a parasol or other means.
