Working in Manual mode:
In manual mode the 873's self-leveling mechanism is disengaged
so that you can set the laser lines at any slope you require.
1. Remove the laser from the case and place it on a flat,
vibration free surface or tripod.
2. Press manual mode button. The manual mode indicator is lit
and the unit projects crossed lines without self-leveling.
3. Choose the beams you want to use by pushing the Beam
Selector.
4. Now you can tilt the laser as needed to mark the desired
slope. Use the folding legs to adjust the angle and the height.
5. To turn the laser off, press the Manual button again.
6. Before moving the laser level be sure to switch laser to the
OFF position which engages the lock protect mechanism.
