located in the base of the unit.
‣It is recommended that the battery pack be completely charged before use.
‣Charging time is approximately 5 hours.
‣Use of the unit over time and changes in temperature may cause increases
or decreases in charging and operation time.
‣The power indicator light will flash when the battery is low. The unit should
be re-charged as soon as possible.
‣To charge the unit insert the charger into the port on the battery pack.
Progress will be shown by the power indicator display on the charger as below:
Red (flashing) = Charger and battery are not connected.
Red (constant) = Battery is charging.
Green (constant) = Battery is charged.
‣There is an additional alkaline battery pack included in you kit which may be
used in place of the rechargeable pack.

Ensure the location is clear of traffic.
‣Attach the laser to a tripod and place on a level surface.
Ensure the unit is secured correctly and tightened in position.
Vertical Set Up
‣Select a place as close as practical to the work site.
Ensure the location is clear of traffic.
‣Place the laser onto a level surface with the control panel
facing upwards.
Operation
‣To turn the unit on press the power button. Self levelling will
commence and the laser will begin to rotate.

powered off and on again to reset its level position.
Speed control
‣Press the speed control button to cycle through various rotational speeds,
indicated by the speed indicator light.
Scanning mode
‣To focus the laser beam between two points press the scanning mode
button. Pressing the button multiple times will adjust the angle of the beam.
‣To cancel scan mode press the scanning mode button several times
to cycle through to full rotation.
Rotation
‣ Whilst the unit is in scanning mode press the clockwise rotation or counter
clockwise rotation button to change the rotation of the laser head.

11
Setting up a grade
‣ Once the unit has levelled off and started rotating you can begin a slope or grade.
Adjusting the X-Axis

you wish to grade.
‣Press the manual / automatic mode button on the control panel.
‣The unit is now in manual mode and the X-axis indicator will be lit.
