OPERATION
Setup
The laser mounts to any 5/8” x 11 tripod (flathead or domed) or can rest on any stable
flat surface (floor, bricks, etc.). Position tripod, attach laser, then adjust tripod until
rough leveled (within ±4° self-leveling range).
Turning on the Laser
Press the on/off key to power-up the laser. The unit’s self-checking system will start
automatically. The LEDs will flash if anything goes wrong during the self check
procedure. Battery LED should be green; if batteries are low, LED will be red.
Leveling
When laser is turned on, the level indicator will flash red until unit is level. If it fails to
self-level within 90 seconds, the red LED will be constantly lit. Re-adjust tripod to
bring into self-leveling range. When unit is level, the rotor head will begin spinning
(600 rpm).
Level Alert
If laser is disturbed, the level alert system will stop head rotation. Unless disturbed out
of self-leveling range ( ±4°), unit will self-level and return to operation automatically.
Windy Mode
Windy mode allows continuous operation during high winds, slight vibrations, and
shocks on the job site. It prevents the laser from constantly re-leveling from high
vibration. Selection of Windy mode lowers the sensitivity but does not decrease the
accuracy. To use this mode, press the Windy key.
H.I. Alert
H.I. (height of instrument) alert stops the laser automatically if it’s disturbed,
preventing inaccurate readings. It functions only when selected.
To activate this safeguard, press the H.I. key after the laser has leveled. The H.I.
LED blinks slowly for about 30 seconds before turning solid green.
If laser is disturbed, the head will stop rotating, the green H.I. LED will flash
rapidly, and the red level indicator will come on.
Press the H.I. key to turn off the alert, allowing the laser to level itself.
