1.2 Operation instrument
(1) Power(ON/OFF):Controlling the state of power.
(2) Auto/manual: Push button to switch manual（Remote）or auto leveling.
(3) Left / right spinning:After the laser head speed is set on 0 r.p.m. the left/right
button can change the laser position.
(4) Anti-drift: TheAnti-Drift System, when ON, will signal to the operator that
the instrument has been moved out of level.
The ADS LED will blink slowly when instrument inAnti-Drift System.
The ADS LED will blink quickly when instrument moved out of level.
(5) Angle scanning:Setting 5 sections angle scanning, 0°-10°-45°-90°-180°, the
Left/right button can change the laser position.
(6) Rotating speed:Setting 5 sections rotating speed, 0-60-120-300-600 r.p.m.

2. Directions
2.1. Battery Installment
(1) Take down the cover of battery case at the bottom of the instrument.
(2) Put the batteries into the case according to the right position.
(3) Lay the cover on the box, and then tighten all screws.
2.2 Instrument Placement
2.2.1 Horizontal scanning (manual mode)
Lay the instrument on the tripod or stable flat surface, or even hang it on the wall.
Set up right the instrument, and keep the slope of instrument within the range from
-5° to +5°.
2.2.2 Vertical scanning (manual mode)

- 7 -
Lay the instrument on the flat surface, and keep the slope of instrument
within the range from -5° to +5°.
2.3 Operations
2.3.1 Power
(1) Press the key ON/OFF to bring automatic leveling into function when the
power indicator lights.
(2) When power indicator blink, it shows the voltage of the batteries is
insufficient. Then the rechargeable batteries need to be charged.
(3) Press the Key ON/OFF to close down the instrument.
2.3.2 Leveling
(1) When turned on, the laser beam will start to blink, It will stop winking after

- 8 -
finish leveling.
(2) If the instrument is placed improperly, or the slope of instrument exceeds the
range from -5° to +5°, the mode indicator and the laser beam will wink at the
same time. Then place the instrument properly.
2.3.3 Spinning
(1) Change speed
Press the rotating speed button to control the spinning speed of the laser head.
If press the key repeatedly, the spinning speed of the laser head will
continuously change as follows: 0-60-120-300-600-0 r.p.m.
(2) Stepping spinning
Locate the Key Speeding-up at 0 r.p.m., The laser head will stop spinning.
And press the Key Right- spinning, the laser head will step-move clockwise.If

- 9 -
then press the key Left-spinning, the laser head will step-move
counter-clockwise.
2.3.4 Directional scanning
(1) Press the Key Directional scanning: the laser head will scan directionally. If
press the key repeatedly, the angle of scanning of laser head will continuously
changes as follows: 0, -10°, -45°, -90°, -180°, -0°
(2) Press the Key Left-spinning or the key Right-spinning to change the direction
of scanning.
2.3.5 SlopeAdjustment
Press the remote Key Manual/Automatic when mode indicator lights, the instrument
enters the mode of manual leveling.
(1) Slope of X-axis

- 10 -
Aim the X1-beam to the direction of the slope required to adjust, as depicted
below.
Press the key ←or →to move the laser beam up or down.
(2) Slope of Y-axis
Aim the Y1-beam to the direction of the slope required to adjust.
Press the key ↑or ↓to move the laser beam up or down.
(3) Press the key Manual/Automatic again
when mode indicator goes out, the
instrument will enter mode of
automatic leveling.

3. Recharge battery
(1) When the batteries needs to be charged, connecting the charger with AC.
Insert the plug of charger into the plug hole at the bottom of the instrument
(As depicted below).
(2) If the indicator of charger lights, it shows the batteries are being charged.
(3) If the indicator light of the charger winks, it shows the course of recharging
has ended.
Notices:
1. Using the standard rechargeable batteries of the instrument, recharging will be

finished within 7 hours.
2. Power required for the charger: Frequency: 50-60HZ; Voltage: 85-265V.
3. Charging and using of the instrument can progress simultaneously.
4. If keeping the instrument in storage (or Leave the instrument unused for a long
time), the batteries (dry battery or rechargeable battery) needs to be taken out.
5. Brand-new rechargeable batteries or long-time unused rechargeable batteries
need to be recharged and discharged three times to attain the capacity required.

4. Accuracy Checking
4.1 Horizontal-surface Checking
(1) Place the instrument at the point of 50m in front of wall (or set a scale plate at
the point of 50m away from the instrument), and then adjust the level of the
base approximately to aim the X1 to the wall (or scale plate), as depicted
below:

X2-beam
Approximately
50m

(2) After switching on the power, use the laser detector measuring the h1 of
X1-beam on the wall or scale plate.
(3) Loose the screw of the tripod, and then turn around the instrument 180° to
measure the h2 of X2-beam on the wall or scale plate.
D-value between h1 and h2 ought to be less than 10mm
(4) Check the Y-beam in the same way.
4.2 Horizontal-line Checking
(1) Place the instrument between two walls with the distance of 30m (or two scale
plates with the distance of 30m)
(2) Place the instrument according to horizontal setting and then adjust the
instrument.

(3) Switch on the power, and then measure the middle point of the laser beam on
the wall (or scale plate):hA, hB and hA’, hB’
(4) △1=hA-hA’, △2=hB-hB’
D-value between △1 and △2 ought to be less than 6mm

6. Detector
The Universal Laser Detector
aids in locating and targeting a
visible or invisible beam emitted
by a rotary laser; perfect for use
in outdoor conditions, where
sunlight and distance may make
locating the beam more difficult.
The laser detector includes a rod
clamp which allows to mount the
detector onto square, round or
oval sighting rods.
