Foreword

Thank you for purchasing the Topcon RL-VH3G/A/B Rotating Laser.

It is one the world’s most advanced lasers.

To quickly and effectively use the RL-VH3G/A/B, please read these brief

instructions carefully, and keep them in a convenient location for future refer-

ence.

Handling Precautions

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.

Caution:

Use of adjustment controls or performance procedures other than those speciﬁed herein

may results in hazardous radiation exposure.

Safety Information

In order to ensure the safe use of this product, prevent any danger to the operator or others,

or damage to property, important warnings are placed on the product and inserted in the

instruction manual.

We recommend that you become familiar with the meaning of these Warnings and Cautions

before continuing.

Injury refers to hurt, burn, electric shock, etc.

Physical damage refers to damage to equipment and structure or furnishings.

Display Meaning

WARNING

Ignoring or disregard of this display may lead to death or serious

injury.

CAUTION

Ignoring or disregard of this display may lead to personal injury or

physical damage to the instrument.

Safety Precautions

WARNING

• There is a risk of ﬁre, electric shock or physical harm if you attempt to disassem-

ble or repair the instrument yourself.

Repairs are to be carried out by TOPCON or an authorized dealer ONLY!

• Laser beams can be dangerous and can cause eye injury if used incorrectly.

Never attempt to repair the instrument yourself.

• Laser beams can be dangerous. They can cause eye injury.

Do not stare into beam.

• Risk of ﬁre or electric shock.

Do not use a wet battery.

• May ignite explosively.

Never use an instrument near ﬂammable gas, liquid matter, and do not use in a coal

mine.

• Battery can cause explosion or injury.

Do not dispose in ﬁre or heat.

• Short circuits can cause a ﬁre.

Do not allow a battery to contact other objects when storing it.

CAUTION

Use of controls, adjustment to the laser, or the performing of any procedures other than

those speciﬁed herein may result in hazardous radiation exposure.

DO NOT allow anyone to work directly in the path of the laser beam.

Always make sure the laser is operating above the height of your crews heads.

Exposure to laser light may cause momentary blindness. Always use caution when op-

erating equipment near a laser.

Do not allow skin or clothing to come into contact with acid from the batteries. If this oc-

curs, wash off with copious amounts of water and seek medical attention.

Damaged or broken carrying cases may fall open causing injury, or damage to the laser.

Do not use a carrying case with damaged belts, grips or latches.

It could be dangerous if the instrument falls off of its mount. Please check that you have

mounted the instrument to the wallmount or tripod securely and correctly.

An unstable tripod can pose a potential risk of injury, or damage to the laser.

Always check that screws or leg locks are tight, and tripod is sitting ﬁrmly.

Please note that the tips of tripod can be hazardous, be aware of this when setting up

or carrying the tripod.

Please note that the tips of tripod can be hazardous, be aware of this when setting up

or carrying the tripod.

User Precautions

Laser Safety

This product uses a visible laser beam, and is manufactured and sold in accordance with

“Performance Standards for Light-Emitting Products” (FDA/BRH 21 CFR 1040) or “Radiation

Safety of Laser Products, Equipment Classiﬁcation, Requirements and User’s Guide” (IEC

Publication 825) provided on the safety standards for laser beam.

As per the said standard, this product is classiﬁed as a “Class 3A (IIIA) Laser Product”.

This is a simple product to operate and does not require training from a laser safety ofﬁcer.

In case of any failure, do not disassemble the instrument. Contact TOPCON or your TOP-

CON dealer.

Main Features

Visible Laser Beam

Visible beam lasers enable you to put the lasers beam to work directly on your

work area without the need for a level sensor.

The RL-VH3G is especially easy to see with its green laser beam.

Laser beams are emitted at exact 90° angles as shown below.

The RL-VH3G and RL-VH3A models also emit a laser beam from the bottom which elimi-

nates the need for plumb bobs when centering over a point.

Automatic Beam Focus (RL-VH3A/G Only)

When the target is used, the laser will focus automatically to the target.

(It is also possible to focus manually with operating keys.)

Scanning

When the target is used, the laser

beam automatically searches for

and tracks it.

Continuous Scan

Scanning beam can be "drawn" to

any length (up to 180°) and main-

tained without the aid of the target

for hands free operation.

Vertical rotation

Horizontal rotation

Automatic Line Control

Set the alignment target centered on far con-

trol point when in auto alignment mode, the

laser beam is aligned automatically.

(can also be done manually.)

Automatic Grade Setting

Using alignment target, grade setting will be

done automatically.

(can also be done manually.)

Plumb Finder Mode

Provides a plumb laser spot below the rotat-

ing head to aid laser set-up over an initial

control point.

Instrument Set-up Procedure

Horizontal Rotation

1 Set the instrument on any smooth surface that is

within ±5° of true level. The RL-VH3G/A/B auto-

level system will not function if the unit is placed

more that 5° out of level. For best operation, it is

recommended that it be mounted to a tripod or

the Topcon Wall Mount Model 2C (provided).

Slope can be set in both axes, X and Y. See

"Setting Slope" section, page 28 .
