CAUTION

• Use of controls or adjustment or performance of procedures other than those spec­ified herein may result in hazardous radiation exposure.

• Do not stand or sit on the carrying cases.
It could overturn, causing injury.

• Do not use a damaged instrument case.
It could accidentally open causing damage to the instrument or injury to people.

• Do not place yourself or a reflecting object in the path of the laser beam. If using the
laser outside, avoid positioning it anywhere near ey e le v el to a v oid any possibility of
it striking someone in the eye. If this should happen, visibility could be temporarily
impaired, causing disorientation and possible accidental injury.

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

• 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.

(Safety lock system)

When auto-leveling and height
alert function are active, after the
laser beam emits for one minute,
this function prevents the instru­ment from operating if it is dis­turbed. This insures accurate
control. If the unit is disturbed, all
lamps will blink except battery
power lamp. The ele vation (height
of instrument) should be verified
and re-established if necessary.
This function is not active in the
manual mode.

HOW TO OPERATE

•Set the instrument to the tripod or smooth surface.

•Make sure instrument is roughly level (±3°).

•Press power switch (ON).

1 Remove the battery cover by turning battery cover knob to “OPEN” side.
2 Remove the batteries by pulling out the slide plate.
3 Install the new batteries referring to the illustration on the battery

cover.*1, *2, *3

4 Install the battery cover. By using a coin, tighten the battery cover knob

to “CLOSE” side until the knob does not turn.*4

*1 Replace all 4 batteries with new ones at the same time. Do not mix used and new batteries,

and do not mix different types of batteries together.

*2 Use alkaline dry cells. (Dry cells for movement confirmation are packed in shipment.)

Nickel hydrogen dry cells and nickel cadmium dry cells can be used too, but the operating time
is different from the time of alkaline dry cells.

*3 Generally, performances of dry cell deteriorate temporarily in low temperature, but recover in

normal temperature.

*4 It is important to use a coin or other tool to make sure cover is firmly closed to seal out water.

CHECKS AND ADJUSTMENTS

1

Checking and adjusting calibration

Horizontal calibration of the laser beam can be checked by the
user.

[Checking]

1 Set up a tripod approx. 50m (160ft) from a wall. Mount the instrument

on the tripod, facing the X1 side toward the wall.

2 Turn the instrument on and allow auto-leveling to complete.
3 Put the laser sensor in fine detection mode by pressing the On-Grade

precision switch.

4 By using the laser sensor, mark the center position of laser beam on

the wall. (X1)

5 Turn off the instrument.

Loosen the tripod screw, rotate the instrument 180 degrees and re­secure it on the tripod. The X2 side of the instrument f aces to ward the
wall.
When rotating the instrument, avoid changing the height.

6 Turn the unit on again and allow auto-leveling to complete.
7 By using the laser sensor, mark the center position of laser beam on

the wall. (X2)

8 If the difference value of marked two laser beam heights (difference

value of X1 and X2) are less than 7mm, adjustments are not needed.
The difference value is greater than 7mm, adjust the instrument as
described in right. *

9 Check the X1 (handle) side as the same way.

*If the difference value is greater than 60mm (2 3/8 inches), contact your
Topcon dealer.

[To calibrate the X axis ]

1 Face the X1 side of the instrument (panel side) tow ard a w all, press the Power

switch while pressing the height alert OFF switch.
Then the height alert OFF lamp will light, and manual mode ON lamp will blink.

2 Press the height alert OFF switch to calibrate the X axis. The manual mode

ON lamp will light. When auto-leveling finishes, the laser beam will emit.

3 Using the laser sensor, mark the on-grade height of laser beam on a wall.
4 Rotate the instrument 180 degrees to face X2 side toward a wall.
5 In the same way as step 3 , mark the on-grade height of laser beam on a wall.
6 By pressing the manual mode ON switch (laser beam moves up), or Power

switch (laser beam moves do wn), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps

7 Press the height alert OFF switch to memorize the new laser beam calibration.

The height alert OFF lamp will blink. P o wer will shut off automatically when the
calibration memorization is complete.

[To calibrate the Y axis ]

1 Face the Y1 side of the instrument (handle side) toward a wall, press the

Power switch while pressing the height alert OFF switch.
Then the height alert OFF lamp will light, and manual mode ON lamp will blink.

2 Press the Power switch again. The auto leveling lamp will light.
3 Press the height alert OFF switch to calibrate the Y axis. The auto leveling

lamp will light.

4 Using the laser sensor, mark the on-grade height of laser beam on a wall.
5 Rotate the instrument 180 degrees to face Y2 side toward a wall.
6 In the same way as step 4 , mark the on-grade height of laser beam on a wall.
7 By pressing the manual mode ON switch (laser beam moves up), or Power

switch (laser beam moves do wn), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps

8 Press the height alert OFF switch to memorize the new laser beam calibration.

The height alert OFF lamp will blink. P o wer will shut off automatically when the
calibration memorization is complete.

To discontinue calibration the instrument, press the Power
switch while pressing the height alert OFF switch.

[Checking]

1 Set up the laser centered between two walls approximately 40m (131ft) apart. Orient the instrument

so one axis, either X or Y, is facing the walls.

2 Locate and mark the position of the rotating laser beam on both walls using the laser sensor.
3 Turn off the instrument and move the instrument closer to wall A (1m to 2m /3 ft to 6 ft).

Do not change the axis orientation of the instrument. Turn the instrument on.

4 Again locate and mark the position of the rotating laser beam on both walls using the laser sensor.
5 Measure the distance between the first and second marks on each wall.

If the difference between each set of marks is less than 4mm (5/32 of an inch), no error exists.

*If the difference value is greater than 4mm(5/32 inch), contact your Topcon dealer.

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.
