Assembly
Measuring Tool Power Supply
The measuring tool can be operated either with conventional
non-rechargeable batteries or with a Bosch lithium-ion bat-
tery.
Operation with Rechargeable Battery
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your measuring tool.
Note: The use of batteries unsuitable for your measuring tool
can lead to malfunctions or damage to the measuring tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". A protective circuit
switches the measuring tool off when the battery is drained.
Do not switch the measuring tool back on after it has
u
been switched off by the protective circuit. This can
damage the battery.
To insert the charged battery (12), slide it into the battery
bay (11) until you feel it engage.
To remove the battery (12), press the release buttons (15)
and pull it out of the battery bay (11). Do not use force to
do this.
Operation with Non-Rechargeable Batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
The batteries are inserted into the battery adapter.
The battery adapter is intended only for use in desig-
u
nated Bosch measuring tools and must not be used
with power tools.
To insert the batteries, slide the cover (13) of the battery
adapter into the battery bay (11). Place the batteries into
the cover as per the illustration on the sealing cap (16).
Slide the sealing cap over the cover until you feel it click into
place.
To remove the batteries (14), press the re-
lease buttons (15) of the sealing cap (16) and
pull off the sealing cap. Make sure that the bat-
teries do not fall out. To do this, hold the meas-
uring tool with the battery bay (11) facing up-
ward. Remove the batteries. To remove the cover (13) from
inside the battery bay, reach into the cover and pull it out of
the measuring tool, applying light pressure to the side wall as
you do so.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
Bosch Power Tools
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Battery Charge Indicator
The battery charge indicator (4) shows the state of charge of
the rechargeable battery/non-rechargeable batteries:
LED State of charge
Green continuous light 100–75%
Yellow continuous light 75–35%
Red flashing light <35%
No light – Rechargeable battery defective
– Non-rechargeable batteries
drained
If the rechargeable battery or non-rechargeable batteries are
running low, the laser lines will gradually become dimmer.
Immediately replace a faulty rechargeable battery or any
empty batteries.
Working with the RM 2 rotating mount (see
figures A1–A3)
You can use the rotating mount (23) to rotate the measuring
tool 360° around a central, always visible plumb point. This
enables you to set up the laser lines without having to
change the position of the measuring tool.
You can use the fine adjustment screw (24) to align vertical
laser lines precisely with reference points.
Place the measuring tool with the guide groove (1) on the
guide rail (20) of the rotating mount (23) and slide the
measuring tool all the way onto the platform.
To disconnect the measuring tool, pull it off the rotating
mount in the opposite direction.
Rotating mount positioning options:
– Standing on a flat surface,
– Screwed to a vertical surface,
– On metallic ceiling strips using the ceiling clip (25),
– On metallic surfaces using the magnets (21).
Operation
Starting Operation
Protect the measuring tool from moisture and direct
u
sunlight.
Do not expose the measuring tool to any extreme tem-
u
peratures or fluctuations in temperature. For example,
do not leave it in a car for extended periods of time. If it
has been subjected to significant fluctuations in temper-
ature, first allow the measuring tool to adjust to the ambi-
ent temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of
the Measuring Tool", page 26).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
