On-floor applications
Turn on the unit with the ON / OFF
switch (1). The laser lines now produce
four marks at 90° angles on the floor.
These projected lines allow tiles to be
laid easily, yet precisely. The 90° lay
edge (4) and the contact surface (5)
make it easy to align the first floor tile.
3
Wall applications
Mount the device on the wall for horizontal and vertical
levelling. Then align the device with the vials.
4
Mounting on the wall
1. Place device on the wall.
2. Push the special pins through
the appropriate holes.
!
Regularly check the calibration before use, after
transport and after extended periods of storage.
5
Checking the vertical line
Fix a plumb bob with a line at least 2.5 m in length on the
wall, making sure that the bob can swing freely. Switch on the
laser, direct the lines at the plumb and align the bubble levels (2).
The precision is within tolerance if the deviation between the
laser line and plumb line is not greater than 0.5 mm / m.
Calibration
The measuring device should be calibrated and tested on
a regular basis to ensure it is accurate and working properly.
We recommend the measuring device is calibrated every
1 - 2 years. If necessary, contact your distributor or the
UMAREX-LASERLINER service department.
