"ON" button: open laser, directly to use ,Top slope mode button: Long press boot, into slope mode, laser will flash slowly., the
laser line is tilted
The button introduction:
The laser level has three laser windows, each window can launch 4D laser lines, totally 16 laser lines(4 laser lines combine to a
plane). Every time click on the button, there will be 4 laser lines of a plane. Attention: There are at least 4 laser lines, it
can not keep 1 or 2 laser lines
Product Highlights:
The 4D laser is a cross line laser level. This unit is self-leveling with accuracy range of within ± 3°. The working range of this
laser is up to 20m, depending on the work area’s illumination.
Design:
The 4D laser level is a compact, practical option for basic cross line leveling work. Measuring at 1/4 ", the laser can fit
comfortably in the palm of your hand. It has a hard plastic housing to protect the laser beams and pendulum leveling system
within. The housing has a ribbed rubber casing that protects it from scratches while giving extra friction to make it slip
resistant.
Mounting Options:
The 4D laser level has one mounting nut with a 1/4 " thread at the bottom of the unit. This allows you to mount it either to a
bracket or a tripod for security. The unit can be placed on a regular surface, but securing it usually guarantees less movement
for more accurate work.
Leveling function:
Once the pendulum is in unlocked condition, the instrument will be self-leveling within 4 'when the unit is using out of the
leveling range, laser lines and main indicator will keep flashing.
Powerful laser line, before use it, do not look directly into the laser, switch lock, protect children
Note:
The green brightness of the laser light is very strong, it will produce projection or Stray light in the mirror or plane.all 4D
green laser can not solve this problem .
