It combines the original spirit level, theodolite, crossed function. It will be an accurate projection of the laser line alignment 7m ± 1mm work on the work object, make the construction process more convenient, more time and more effort, while capable of high accuracy to ensure construction quality. 1 , before first use , unscrew the battery cover counterclockwise fixed knob , remove the battery cover and three rechargeable batteries or alkaline batteries under ” – , +” sign into the battery holder , then replace the battery cover and tighten the battery mounting buttons. 2 , the instrument is placed on the ground or on a tripod, and placed on a tripod , the need to manually turn the instrument on the center of the tripod center nut or screw fastening. When necessary, unscrew the three adjustable feet helix. 3 , adjust the three leveling screws, circular level bubble into the black circle. 4 , the power switch to the “ON” position , power , and automatic discharge compensator self-locking state, so that the level of compensation can be automatically corrected. Turn the power switch to “OFF” position , turn off the power while the compensation is automatic self-locking state. Instrument has four operating modes : H/VH/2VH/4VH (or 3VH). Power, the operating mode of the instrument is H , horizontal laser light , if necessary, by function can work mode selection switch. 5 , on the location of the instrument on the ground aimed at the target point , then rotate the upper part of the instrument , making it probably the vertical line at the target , and finally turn the trim knob, so that the vertical line at the target accurately. 6 , at work, for some reason, the instrument tilt caused by more than ± flashes to indicate an alarm , then adjust the three leveling screws so that the original vial blisters into the black circle. 1 x Protective box. 1 x 8 lines 3 points Laser Level (included Li battery). 1 x EU Power supply(Input:AC110-240V). 1 x Safety glasses.
