The TAURUS is classified as a class 3R Laser Product according to IEC Standard Publication
60825-1 Ed.2.0: 2007 and United States Government Code of Federal Regulation FDA CDRH
21CFR Part1040.10 and 1040.11 (Complies with FDA performance standards for laser products
except for deviations pursuant to Laser Notice No.50, dated June 24, 2007.)
C
WARNING
• Use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiation exposure.
• Follow the safety instructions on the labels attached to the instrument as well as in this manual to
ensure safe use of this laser product.
• Never intentionally point the laser beam at another person. The laser beam is injurious to the eyes
and skin.
• The laser beam is emitted when the power is turned ON. Before turning the power on, make sure
that persons are not located in the path of the laser beam.
• Secure the instrument in a fixed position before it is used. If it is necessary to hold the instrument by
hand, make sure that persons are not located in the area before the laser is emitted.
• Do not look directly into the laser beam. Doing so could cause permanent eye damage.
• Do not stare at the laser beam. Doing so could cause permanent eye damage.
• Never look at the laser beam through a telescope, binoculars or other optical instruments. Doing so
could cause permanent eye damage.
C
CAUTION
• Perform checks at start of work and periodic checks and adjustments with the laser beam emitted
under normal conditions.
• When the instrument is not being used, turn off the power.
• When disposing of the instrument, destroy the battery connector so that the laser beam cannot be
emitted.
• Operate the instrument with due caution to avoid injuries that may be caused by the laser beam
unintentionally striking a person in the eye. Avoid setting the instrument at heights at which the path
of the laser may strike pedestrians or drivers at head height.
• Never point the laser beam at mirrors, windows or surfaces that are highly reflective. The reflected
laser beam could cause serious injury.
• Only those who have received training as per the following items shall use this product.
- Read the Operator's manual for usage procedures for this product.
- Hazardous protection procedures (read this chapter)
- Requisite protective gear (read this chapter)
- Accident reporting procedures (stipulate procedures beforehand for transporting the injured and
contacting physicians in case there are laser-induced injuries). "
• Persons working within the range of the laser beam are advised to wear eye protection which
corresponds to the laser wavelength of the instrument being used.
• Areas in which the laser is used should be posted with a standard laser warning sign.

REPLACING THE BATTERIES
Rotating laser
1
Turn the battery cover knob to OPEN and remove the battery cover.
2
Pull out the slide board and remove the batteries.
3
Insert new batteries as shown by the illustration on the battery cover.
4
Replace the battery cover to its original position and turn the battery cover knob to LOCK.
G
• Always replace all 4 batteries at the same time. Do not use a combination of old and new batter-
ies.
• Alkaline batteries are recommended for use with the instrument. (Batteries included upon ship-
ment are for confirmation of operation by the user.) Commercially-available manganese, Ni-CD
and Ni-MH batteries may be used but the operating time will differ to that for alkaline batteries.
• Battery performance generally deteriorates temporarily at low temperatures.However, returning
to room temperature restores normal performance.

PRECAUTIONS
Before starting work or during operation, check that the instrument is functioning correctly and per-
formance is normal.
TAURUS should be used with the level sensor (LS-1), a standard equipment. We do not guarantee
precision noted in this instruction manual when used with other level sensors.
STORAGE PRECAUTIONS
Always clean the instrument after use.
Use a clean cloth moistened with neutral detergent or water.
Never use an abrasive cleaner, ether, thinner, benzene, or other solvents.
Always make sure the instrument is completely dry before storing. Dry any moisture with a soft,
clean cloth.
PRECAUTIONS REGARDING LONG-TERM STORAGE
Remove batteries before storing when the instrument will not be used for periods on 1 month or
more.Batteries may leak fluid when left inside the insturment causing malfunction.
C
CAUTION
E
When mounting the instrument to the tripod, tighten the centering screw securely. Fail-
ure to tighten the screw properly could result in the instrument falling off the tripod,
causing injury.
E
Tighten securely the leg fixing screws of the tripod on which the instrument is mounted.
Failure to tighten the screws could result in the tripod collapsing, causing injury.
D
Do not carry the tripod with the tripod shoes pointed at other persons. A person could
be injured if struck by the tripod shoes.
E
Keep hands and feet away from the tripod shoes when fixing the tripod in the ground.
A hand or foot stab wound could result.
E
Tighten the leg fixing screws securely before carrying the tripod. Failure to tighten the
screws could lead to the tripod legs extending, causing injury.
C
WARNING
D
Do not use voltage other than the specified power supply voltage. Fire or electrical
shock could result.

Class 3R Laser Product
For the safe use of the product and prevention of injury to operators and other persons as well as
prevention of property damage, items which should be observed are indicated by an exclamation
point within a triangle used with WARNING and CAUTION statements in this operator's manual.
The definitions of the indications are listed below. Be sure you understand them before reading the
manual's main text.
Make sure all of the following are included.
13. Indicator
When moving the level sensor and detecting the datum position,
"====" (normal precision) or "
-------
" (high precision) is indicated.
Directional arrows and audio signals assist in locating the on-
grade position as the laser strikes the beam receiving window.
(Top of level sensor is 36mm (1 5/12") from on-grade index for
offset marking.)
The indicators are located on front and back sides of the instru-
ment.
14. Beam receiving window
Turn the beam receiving window side towards TAURUS to detect
the laser beam.
15. Power switch
Turns the detector ON/OFF.
Auto-cut off function
The power will be turned off automatically if no laser beam is
detected for approximately 20 minutes. (To turn on the level sen-
sor, press the power switch again.)
16. Precision Setting Shifting Switch
Two leveling precision options are available, normal precision
(±2mm) and high precision (±1mm). By pressing this switch, the
precision options are switched alternately. Confirm the selected
precision option by viewing the indicator. (Normal precision is
set when turning on the power switch.)
17. Audio tone switch
By pressing this switch, ON/OFF of buzzer sound is switched
