Inserting/Replacing The Batteries; Putting Into Operation; Measurement Functions - Bosch PCL 1 Operating Instructions Manual

Protect the unit from strong impacts and falls. Damage to the unit can
s
degrade the accuracy.
After a strong impact or fall, check the laser line by comparing with a
known horizontal or vertical reference line.
Transport and store the unit in the protective bag 8.

Inserting/Replacing the Batteries

Use Alkali-Manganese batteries exclusively.
Open the battery compartment cover 5 and insert the batteries provided.
When inserting the batteries, pay attention to the correct polarisation.
Always replace all batteries at the same time. Use only batteries from a
single manufacturer and with the same capacity.

Putting into Operation

Switching on:
When switched on, the instrument immediately emits a laser beam
s
from the outlet opening 3. Do not direct the laser beam at persons
or animals and do not look directly into the laser beam (espe-
cially not with optical instruments).
Press the on/off switch 2 in the "ON" direction. The instrument always
starts in the crossed line mode with levelling control.
Switching off:
Press the on/off switch 2 in the "OFF" direction. The instrument is
switched off. The laser unit is locked.

Measurement Functions

Operation with Levelling Control
With levelling control, the instrument automatically compensates for une-
venness within the self-levelling range of approx. 5°. The levelling is com-
plete as soon as the laser line no longer moves. If automatic levelling is
not possible, for example when the surface on which it is standing devi-
ates more than 5° from the horizontal, a warning signal sounds and the
laser switches itself off. In this case, reposition the instrument to horizon-
tal and wait for the self-levelling to complete.
Crossed Line Operation (see Fig.
Place the instrument on a firm horizontal surface or attach to a tri-
pod and switch on. The laser is in crossed line operation with lev-
elling control and produces a horizontal and a vertical line.
Horizontal Operation (see Fig.
Press the measuring mode button "mode" 1 once. The laser is in
horizontal operation with levelling control and produces a horizontal
line.
Vertical Operation (see Fig.
Press the measuring mode button "mode" 1 again or press twice
directly after switching on. The laser is in vertical operation with lev-
elling control and produces a vertical line.
