Product Features

? These series products (NK-520 series) adopt diode laser beam, the waveform length of which is 635nm. The level laser 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 degree. ? The focus of those beams is called Zenith. Automatic self-leveling. Indoor and outdoor (long distance) mode. 360 degree rotatable, adjustable structure for accurate targeting. Water-proof, dirt-proof, sensitive buttons. Vertical beam button. ? Horizontal beam button. Bubble vials. Outdoor mode button. Vertical laser emission window. Horizontal laser emission window. Power switch/lock. Thumbscrew. Adjustable bracket. ? Maintenance: a. Never let any liquid get inside the device, never immerse any part of the device into a liquid. b. Avoid shock and drop during operation and storage. c. Please turn off the device before moving the device or it may affect the accuracy. d. Keep the laser emission window clean. Use soft cloth to wipe the glass lens if there is dirt. e. Take off the battery and store the device in the kit box if the device is not in use for long time. ? Operation instructions: a. Place the device on a tripod or a flat surface. Ensure the device is approximately on horizontal level. b. Rotate the power switch clockwise to turn on the device. Laser beams are emitted with the green LED ON. c. Rotate the device to make the laser beam pointing at the target. d. Turn the thumb screw to locate the exact position. e. After every task, turn the power switch anticlockwise to turn off the device.
