Note: The Y axis grade will be at a 90 degree angle from the X axis grade
output. Press < to match a positive slope in Y and > to match a negative
slope.

hours before first use.
Charging the Battery
1) Remove the charging connector cover on the side of the laser. Insert the
charger plug and fully engage the threads.

illuminate on the charger.
The LT300 can be charged while working. If electricity is available on the job
