Bosch Power Tools
Assembly
Power Supply
The measuring tool can either be operated with commercially
available batteries or with a Bosch lithium-ion battery pack.
Operation with Battery Pack
Note:
Use of battery packs not suitable for the measuring tool
can lead to malfunctions of or cause damage to the measuring
tool.
Note:
The battery pack is supplied partially charged. To en-
sure full capacity of the battery pack, completely charge the
battery pack in the battery charger before using for the first
time.
Use only the chargers listed in the technical data.
Only
these battery chargers are matched to the lithium-ion bat-
tery of your measuring tool.
The lithium-ion battery pack can be charged at any time with-
out reducing its service life. Interrupting the charging proce-
dure does not damage the battery pack.
The “Electronic Cell Protection (ECP)” protects the lithium-
ion battery pack against deep discharging. When the battery
pack is discharged, the measuring tool is switched off by a
protective circuit.
Do not switch the measuring tool back on after it has
been switched off by the protective circuit.
The battery
pack can be damaged.
To
insert
the charged battery pack
9
, slide it into the battery
port until you feel it engage.
To
remove
the battery pack
9
, press the unlocking buttons
12
and pull the battery pack out of the battery port.
Do not
exert any force.
Operation with Batteries
The batteries are inserted into the battery adapter.
The non-rechargeable battery adapter is intended only
for use in designated Bosch measuring tools and must
not be used with power tools.
To
insert
the batteries, slide the cover
10
of the battery
adapter into the battery port. Place the batteries in the cover
as shown in the illustration on the sealing cap
13
. Slide the
sealing cap over the cover until you feel it click into place.
To
remove
the batteries, press the unlocking but-
tons
12
of the sealing cap
13
and pull off the seal-
ing cap. Take care that the batteries do not fall out.
To do so, hold the measuring tool with the battery
port facing upward. Remove the batteries. To re-
move the inside cover
10
from the battery port,
reach into the cover and pull it out of the measuring
tool by applying light pressure to the side wall.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
Remove the batteries from the measuring tool when
not using it for extended periods.
When storing for ex-
tended periods, the batteries can corrode and self-dis-
charge.
Battery Status Indicator
The battery status indicator
4
shows the charge condition of
the battery pack or batteries:
Immediately replace a fault battery pack or empty batteries.
Working with the Rotating Mount RM 2
(see figures A1 – A3)
You can use the rotating mount
22
to rotate the measuring
tool 360° around a central, always visible plumb point. This
enables you to align the laser lines precisely, without having
to change the position of the measuring tool.
You can use the fine adjustment knob
23
to align vertical laser
lines precisely with reference points.
Place the measuring tool with the guide groove
17
on the
guide rail
19
of the rotating mount
22
and slide the measuring
tool to the stop onto the platform.
To disconnect, pull the measuring tool in the opposite direc-
tion from the rotating mount.
Positioning possibilities of the rotating mount:
– standing on a flat surface,
– screwed to a vertical surface,
– on metallic surfaces using the magnets
20
,
– on metallic ceiling strips using the ceiling clip
24
.
Operation
Initial Operation
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature.
As an example, do
not leave it in vehicles for a long time. In case of large vari-
ations in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
Avoid heavy impact or falling of the measuring tool.
Af-
ter heavy exterior impact on the measuring tool, an accura-
cy check should always be carried out before continuing to
work (see “Levelling Accuracy”).
Switch the measuring tool off during transport.
When
switching off, the levelling unit is locked. Else it can be
damaged in case of intense movement.
Switching On and Off
To
switch on
the measuring tool, slide the On/Off switch
18
to
position
“
”
(for working without automatic levelling) or to
position
“
”
(for working with automatic levelling).
As soon as it is switched on, the measuring tool emits laser
lines from the exit openings
