Operation Manual

Vertical check

You must create a reference to perform this test. Fasten a plumbline near to

the wall. The laser unit should now be set up in front of this reference mark

(distance Y) and the vertical laser line compared with it.

The discrepancy between the centre of the laser line and the reference mark

should be no greater than 1 mm ( 3/64” ) over a length of 2 m ( 8 ft ).

Checking plumblining

1. Switch the unit on

2. Place the laser so that its down beam is over a reference mark on the floor.

3. Locate the position of the up beam on the ceiling and make a mark.

4. Rotate the laser 180° and realign the down beam over the reference mark

on the floor.

5. Locate the position of the up beam on the ceiling and make a mark.

6.Measure the di erence D between the two marks on the ceiling, which will be

twice the actual error. The di erence may not be greater than: 3 mm in 5 m

(1/8“ in 16‘5“).

Replacing the batteries

Slide the battery cover (4) in the direction of the arrow and insert new

batteries in accordance with the symbols in the battery compartment.

Suitable batteries can also be used.
