1. Features and functions
LS526 (red laser)/LSG526 (green laser) full automatic rotating laser can project self-leveling horizontal laser plane and
plumb up line, and vertical laser plane and horizontal line. It supplies accurate horizontal reference for working
construction lay out and calibration indoor and outdoor. It is convenient for operation and widely used.
Features:
※ Electronic auto-leveling, when beyond the range, the instrument stops rotating and sound indication.
※360° rotary laser, able to work horizontally and vertically
※ Able to set different rotation speed and area scanning angle
※ Able to unbalance alarm in TILT mode. The instrument stops rotating when knocked, in order to make sure work
accurately.
※ Slope mode function could set single axis or double axis slope
※ Accuracy self-calibration function
※ Timing power-off function
※ Remote operation function
※ Able to connect with tripod through 5/8'' thread.
※ Rainproof and dustproof
2. User safety
※ Laser output sign lies near the output aperture.
※ Do not stare into laser beam directly.

    the instrument will power off automatically. The function of the rotation speed switch key, self-leveling key, area scanning function key and slope function key on the remote control is same with the instrument. 5. Self-check and Calibration The instrument must be self-checked after service for a certain time or before operation in a major project. If the accuracy is found beyond tolerance, user makes some adjustment according to methods as follows.
