Laser Level User Manual
I.Introduction
These series products adopt diode laser beam, the waveform
length of which is 635nm. The laser level can generate two
or more laser sectors and one plump down point. The sector
is formed by one horizontal beam and one or more vertical
beams that is reflected on the wall. The included angle of
every two vertical beams is 90˚. The focus of those beams
is called Zenith.
Automatic self-leveling
Indoor and outdoor(long distance) mode
360˚ rotatable ; Adjustable structure for accurate targeting
Water-proof, dirt-proof, sensitive buttons
VI.Maintenance
III. Operation instructions
1. Place the device on a tripod or a flat surface. Ensure the
device is approximately on horizontal level
Note: If the device is out of level, the laser will be shut down
automatically with audio alert.
2. Rotate the power switch clockwise to turn on the device.
Laser beams are emitted with the green LED ON.
3. Rotate the device to make the laser beam pointing at the
target.
4. Turn the thumb screw to locate the exact position.
5. After every task, turn the power switch anticlockwise to turn
off the device.

Never let any liquid get inside the device. Never immerse
any part of the device into a liquid.
Avoid shock and drop during operation and storage.
Please turn off the device before moving the device or it
may affect the accuracy.
Keep the laser emission window clean. Use soft cloth to
wipe the glass lens if there is dirt.
Take off the battery and store the device in the kit box if
the device is not in use for long time.
