Inserting/Replacing the Battery

Alkali-manganese batteries are recommend-
ed for the measuring tool.
To open the battery lid 6, press on the latch 7
and fold the battery lid up. Insert the batter-
ies. When inserting, pay attention to the cor-
rect polarity according to the representation
on the inside of the battery compartment.
When the battery indication 8 flashes, the
batteries are weak. When the battery indica-
tion flashes for the first time, the measuring
tool can still be operated for approx. 2 h.
When the battery indication 8 lights up con-
stantly, measuring is no longer possible. The
measuring tool automatically switches off
after a short time.
Always replace all batteries at the same time.
Only use batteries from one brand and with
the identical capacity.
Remove the batteries from the measur-
ing tool when not using it for extended
periods. When storing for extended
periods, the batteries can corrode and
discharge themselves.
Operation

Initial Operation

Protect the measuring tool against mois-
ture and direct sun irradiation.
Do not subject the measuring tool to
extreme temperatures or variations in
temperature. As an example, do not
Bosch Power Tools
leave it in vehicles for longer periods. In
case of large variations in temperature,
allow the measuring tool to adjust to the
ambient temperature before putting it in-
to operation. In case of extreme tempera-
tures or variations in temperature, the
accuracy of the measuring tool can be
impaired.
Avoid heavy impacts or falling down of
the measuring tool. If the measuring tool
has been exposed to extreme conditions,
you should always check the accuracy of
the measuring tool before continuing your
work (see "Angular accuracy", page 22).
Switching On and Off
To switch on the measuring tool, press the
On/Off button 3 once briefly. Immediately
after the switching on, the measuring tool
projects the three laser lines 0°, 45° and 90°
from the exit openings 1. Furthermore, the
battery indication 8 lights up for 3 s.
Do not point the laser beam at persons
or animals and do not look into the laser
beam yourself, not even from a large dis-
tance.
When the On/Off button 3 is pressed a sec-
ond time, the measuring tool switches over
from 3-line operation to 2-line operation:
Only the 0° and the 90° laser lines are pro-
jected.
To switch off the measuring tool, press the
On/Off button 3 a third time.
