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.

Safety Cautions
WARNING
There is a risk of fire, electric shock or physical harm if you attempt to disassemble or repair the instrument
yourself.
This is to be carried out by TOPCON or an authorized dealer, only!
Laser beam can be dangerous, and can cause eye injury if used incorrectly.
Never attempt to repair the instrument yourself.
Cause eye injury or blindness.
Do not stare into beam or view directly with optical instruments.
Risk of fire or electric shock.
Do not use a wet battery.
May ignite explosively.
Never use an instrument near flammable gas or liquid matter, and do not use in a coal mine.
Battery can cause explosion or injury.
Do not dispose in fire or heat.
The short circuit of a battery can cause a fire.
Do not short circuit battery when storing it.

CAUTION
Use of controls or adjustment or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
Let the laser beam reach the aimed object or the target without anybody else in the laser beam path. When
operating in an open area, avoid radiating laser beam at eye level. It is quite possible for the beam to enter into
one’s eyes, and it is possible to lose visual sight temporarily, and lose one’s caution and awareness of other
dangers - avoid glaring beam.
Do not allow skin or clothing to come into contact with acid from the batteries, if this does occur then wash off
with copious amounts of water and seek medical advice.
Risk of injury by dropping the instrument or case.
Do not use a carrying case with damaged belts, grips or latches.
It could be dangerous if the instrument falls over, please check that you fix the instrument to the wallmount or
tripod.
Risk of injury by dropping a tripod and an instrument.
Always check that the screws of tripod are tightened.
Please note that the tips of tripod can be hazardous, be aware of this when setting up or carrying the tripod.
