If the centre of the laser spot makes a clearly circular movement or
if the centre of the spot moves away more than 1mm from the first
marked point an adjustment may be necessary. Call your nearest
Leica Geosystems service workshop.
Checking and Adjusting
Under normal circumstances adjusting the laser plummet is not
necessary.
Checking by turning the instrument by 360°:
1. Install the instrument on the tripod and level up.
2. Switch on laser plummet and mark centre of the red point.
3. Turn instrument slowly by 360° and observe the red laser spot.
Checking the laser plummet must be carried out on a bright, even
and horizontal surface (e.g. sheet of paper).
