WARNING
•
•
While the instrument is operating, be careful not to expose your
eyes to the emitting laser beam (red light source). Exposure to a
laser beam for a long time may be hazardous to your eyes.
(Laser beam: Equivalent to class 2 Laser level)
Do not try to dismantle the instrument. Have it repaired by your
dealer or authorized repair shop. Dismantling it by yourself may
worsen the trouble.
CAUTION
•
•
Do not stand on the carrying case.The case could turn over
causing the person standing on it to fall.
When attaching the instrument to a tripod, make sure the
instrument is securely fixed to the tripod and then securely
tighten the tripod leg clamps. If not securely fastened and/or
tightened, the main unit could fall off or the tripod could fall over.
When carrying the tripod, be careful so that the tripod shoes do
not strike anyone.
When setting the tripod, make sure not to stab someone’s hand
or foot with the tripod shoes.
Operate this laser product with the height of laser avoiding that
of eyes of car drivers and pedestrians.
•
•
•
Avoid putting the laser on a highly reflective material such as mirror.
When disposing of this instrument, take a measure such as
breaking the battery cap so that the laser will not be emitted.

Precautions
The instrument should not be stored or used in extreme temperatures or
job on a place subject to rapid change of temperature.
(Refer to the ambient temperature range) The instrument may not
function properly if used out of the ambient temperature range.
5

Put into the carrying for storage and place in a dry area not subject to
vibration, dust or high moisture.
When storage and usage temperatures are widely different, leave the
instrument in the case until it can adjust to the surrounding temperature.

The detector (option) may react to the Laser beam and further react to
the Fluorescent lamp, Site lamp, modulated light or an electric wave
(in or near the airport etc.) and so correct measurement is sometimes not
performed near these places. In these cases, please measure again after
stopping or cutting these modulated light or wave etc.
The instrument should be transported or carried carefully to avoid
impact or vibration.

The instrument should be stored in the carrying case and packed with
cushioning material and handled with care as ‘Fragile’.
Check the ‘check and adjustment of the datumpoint’of page 35 in this
manual and be sure to check to see if error exists before the instrument
is used. After the instrument has been stored a long time or it has
suffered an impact or vibration, be sure to check to see if trouble exists
before use. If any trouble exists, adjust or have it repaired.

To be selected for detecting the reference level with accuracy.
Low accuracy detection:
To be selected if high accuracy is not needed or when stable reference
level cannot be obtained due to slight vibration at job site.
High accuracy
Low accuracy
NOTE:
•
For the detection accuracy to be selected, check with the mark in the
liquid crystal display (see the figure on the above).
The detection accuracy alternates each time the detection accuracy
selection switch is pressed.
•
•
•
High detection accuracy is initiated when the power turns on.
If the point to be measured is distant, the reference level may not be
displayed stably by the influence of heat waves shimming or the
instrument slightly vibrating. Under such conditions,
select ‘Low detection accuracy’.

[Detecting the reference level]
At the measuring point, set the position of the detector nearly to the
height of the beam emitting aperture of the instrument.
Position the detector where the buzzer sound (or the beam reception
display appears) by directing the detecting display nearly toward the
instrument and moving the detector up and down.
Move the detector up and down again according to the beam
reception display (or the buzzer) and obtain the reference level.
Move the detector down as it is positioned high.
The buzzer sound beeps at short intervals.
This is the reference position.
The buzzer sound beeps continuously.
Move the detector up as it is positioned low.
The buzzer sounds lasting beeps intermittently.
NOTE:
•
When detecting the reference level, the detector should face the
instrument in the range of about 40°, to the right and left from
the front.

[Plain rod marking]
After the reference level has been detected, mark a line along the plain
rod’s top or bottom end.
NOTE:

pillars about 40m away so that the ‘X side’of the instrument faces the
‘Wall A’and level it.
2
Operate the instrument and turn on the power to the detector. (use the
detection accuracy initially set.)
Mark the reference point detected for both walls. (A,B)

4
Arrange a pair of target plates (with the same scale) and fix them to the
walls (A and B) so that the center values of the target plates coincide
with the reference point marks.
5
Loosen the center screw of the tripod to turn the instrument 180 for
the ‘X side’to face the ‘Wall B’and tighten the center lock screw again
for the instrument to be leveled again.
