tor is on;
2) Turn the switch knob to the “OFF” position. The tool is
turned off and the battery indicator is off.
4. Auto-leveling mode
1) Place the tool naturally, and turn it on. The tool will auto-
matically level when it is tilted 3°. If the leveling range is
exceeded, the buzzer will flash alarm.
2) If auto-leveling is always not possible, it means the
surface on which the tool stands deviates by more than
auto-leveling range 3° from the horizontal plane. Please
adjust the tilt angle with the adjustable bracket based on
the deviation direction of auxiliary bubble, so as to place
the tool in a position close to level (
≤
3° from the horizon-
tal plane).
5. Turn on/off the horizontal laser
1) Press the “H” key to turn on the horizontal laser. The laser
lights up blue. Press the key again to turn off the horizon-
tal laser.
6. Turn on/off the vertical laser
1) KI100S: Press the “V” key once to turn on two vertical la-
sers; press the “V” key twice to turn on four vertical lasers;
press it again to turn off the vertical laser.
2) KI100S.2: Press the “V” key once to turn on a vertical laser.
3) KI100S.3: Press the “V” key once to turn on a vertical laser;
press the “V” key twice to turn on two vertical lasers.
4) The plumbing dot lights up only when the vertical laser is
on.
7. Lock slash mode
1) When the working knob is at “OFF” position, press the key“
”, the top indicator flashes now, and the tool gets into
lock slash mode.
2) In such mode, press the “H” or “V” key to turn on the
vertical or horizontal laser. At this time, the tool will not
trigger an alarm even if it is at any angle and exceeds the
auto-leveling range; press the “Slash“ button, the laser and
the top indicator are off, and the tool is turned off.
8. Outdoor operating mode
1) Short press the “
” key to enter into the outdoor operat-
ing mode which needs to used with the laser receiver.
9. Working with the tripod (not included)
For general 5/8
″
tripods.
Self-inspection of the accuracy
I. Plumbing dot detection
1. Mount the instrument on a tripod and raise to 1m in height.
Then mark the spot position of plumbing dot.
2. Turn the machine 90° clockwise by three times, and mark
the spot positions of plumbing dot respectively.
3. Measure the maximum spacing H among the four marked
points.
4. Hmax= tool height (m) × nominal accuracy of plumbing dot
(mm/m) × 2
5. If H
≤
Hmax, the level accuracy of the plumbing dot is cor-
rect.
II. Vertical laser line detection
1. Find a transparent door opening. Open the door, put the
instrument on any side of the ground 2.5m away from the
door opening. Turn on the instrument and make the vertical
laser line pass through the middle of the door opening.
After auto-leveling finished, mark a point as A on the inner
ground of the door opening, mark a point as B on the up-
