On/Off switch 14 to position “Off” first and
then switch the measuring tool back on, or
press button 8.

Temporarily Deactivating Automatic
Shut-Off

To deactivate automatic shut-off, hold down
button 8 for at least 3 s with the measuring
tool switched on. If automatic shut-off is
deactivated, the laser lines will flash briefly as
confirmation.

Note: If the operating temperature exceeds
113°F (45°C), automatic shut-off can no
longer be deactivated.

After the next time the measuring tool is
switched off and on, the automatic shut-off will
be activated again.

Setting the operating mode

(see figures B1–F1)

The measuring tool has several operating
modes between which you can switch at any
time:

– Cross-line and point operation: The

measuring tool generates a horizontal
and a vertical laser line facing frontward,
a vertical laser point facing upward and a
vertical laser point facing downward.

The laser lines cross at a 90° angle.

– Horizontal line operation: The measuring

tool generates a horizontal laser line facing
frontward.

– Vertical line operation: The measuring

tool generates a vertical laser line facing
frontward.

If the measuring tool is positioned in the
room, the vertical laser line is displayed on
the ceiling beyond the upper laser point.

If the measuring tool is positioned directly
against a wall, the vertical laser line
generates an almost completely allround
laser line (360° line).

– Point operation: The measuring tool

generates a vertical laser point facing
upward and a vertical laser point facing
downward.

Use button 8 to switch between the individual
operating modes, see table on page 24.

All modes except for point operation can be
selected both with and without automatic
leveling.

Receiver Mode

Receiver mode must be activated to work with
the laser receiver 25, –regardless of which
operating mode is selected–.

In receiver mode the laser lines flash at very
high frequency, enabling them to be detected
by the laser receiver 25.

To switch on receiver mode, press button 6.
Indicator 7 will light up green.

When receiver mode is switched on, the
laser lines are less visible to the human eye.
For this reason, switch receiver mode off by
pressing button 6 again to work without a
laser receiver. Indicator 7 will extinguish.

Automatic Leveling

Working with Automatic Leveling
(see figures B1–E1)

After switching on, the leveling function
automatically compensates irregularities
within the self-leveling range of ±4°. The
measuring tool is leveled in as soon as the
laser lines no longer flash.

If the automatic leveling function is not
possible, e.g. because the surface on which
the measuring tool stands deviates by more
than 4° from the horizontal plane, the laser
beams flash. In this case, bring the measuring
tool to the level position and wait for the self­leveling to take place.

In case of ground vibrations or position
changes during operation, the measuring tool
is automatically leveled in again. To avoid
errors by moving the measuring tool, check
the position of the laser beams with regard to
the reference points upon re-leveling.

Position the measuring tool on a level, firm
support or attach it to the rotating mount 18.

For work with automatic leveling, slide the On/
Off switch 14 to position “On

If the measuring tool is outside of the self­leveling range, the laser lines and/or points
will flash quickly.

Accuracy Check of the Laser Tool

Influences on Accuracy

The ambient temperature has the greatest
influence. Especially temperature differences
occurring from the ground upward can divert
the laser beam.

Because the largest difference in temperature
layers is close to the ground, the tool
should always be mounted on a tripod when
distances exceeding 65 ft (20 m). If possible,
also set up the tool in the center of the work
area.

Apart from exterior influences, device-specific
influences (such as heavy impact or falling
down) can lead to deviations. Therefore,
check the accuracy of the tool each time
before starting your work.

Firstly, check the leveling accuracy of the
horizontal laser line and then the leveling
accuracy of the vertical laser line.

Should the tool exceed the maximum
deviation during one of the tests, please have
it repaired by a Bosch after-sales service.

A

B

180°

– Turn the tool by 180°, allow it to level in and
mark the cross point of the laser lines on
the opposite wall B (point II).

– Without turning the tool, position it close to
wall B. Switch the tool on and allow it to
level in.

A

B

Checking the Height Accuracy

of the Horizontal Line

A free measuring distance of 16 ft (5 m) on
a firm surface in front of two walls A and B is
required for the check.

– Mount the tool onto a tripod, or place it on a
firm and level surface close to the wall A.
Switch the tool on. Select cross-line
operation with automatic leveling.

A

16 ft (5 m)

– Direct the laser against the close wall A and
allow the tool to level in. Mark the center of
the point where the laser lines cross each
other on the wall (point I).

B

– Align the height of the tool (using a tripod or
by underlaying, if required) in such a
manner that the cross point of the laser
lines is projected against the previously
marked point II on the wall B.

A

d

– Without changing the height, turn around
the tool by 180°. Direct it against the wall A
in such a manner that the vertical laser line
runs through the already marked point I.

Allow the tool to level in and mark the cross

point of the laser lines on the wall A (point III).

– The difference d of both marked points I

and III on wall A results in the actual height
deviation of the tool.

apart.

Checking the Leveling Accuracy

of the Horizontal Line

For the check, a free surface of approx. 16 x
16 ft (5 x 5 m) is required.

– Set up the measuring tool on a firm, level

surface between both walls A and B. Allow
the measuring tool to level in while in
horizontal operation.

A

16 ft (5 m)

8 ft (2.5 m)

– At a distance of 8 ft (2.5 m) from the

measuring tool, mark the centre of the laser
line (point I on wall A and point II on wall B)
on both walls.

B

– Align the height of the measuring

tool (using a tripod or by underlaying, if
required) in such a manner that the centre
of the laser line is projected exactly against
the previously marked point II on wall B.

– Mark the centre of the laser line as point

III (vertically above or below point I) on the
wall A.

– The difference d of both marked points

I and III on wall A indicates the actual
deviation of the measuring tool from the
level plane.

The maximum permitted deviation dmax can

apart.

Checking the Leveling Accuracy

of the Vertical Line

For this check, a door opening is required
with at least 8 ft (2.5 m) of space (on a firm
surface) to each side of the door.

– Position the tool on a firm, level surface

(not on a tripod) 8 ft (2.5 m) away from
the door opening. Allow the tool to level in
while in vertical operation with automatic
leveling, and direct the laser beam at the
door opening.

Checking Plumb Accuracy

For this check, a free measuring distance of
approx. 16 ft (5m) between floor and ceiling
on a firm surface is required.

– Mount the measuring tool onto the rotating

mount and place it on the floor.

– Switch the measuring tool on and allow it to

level.

16 ft
(5 m)

– Rotate the tool by 180° and position it on
the other side of the door opening directly
behind point II. Allow the tool to level in and
align the vertical laser line in such a manner
that its center runs exactly through points I
and II.

– Mark the center of the laser line at the
upper edge of the door opening as point IV.

– The difference d of both marked points III
and IV results in the actual deviation of the
tool to the plumb line.

– Measure the height of the door opening.
The maximum admissible deviation is
calculated as follows:

Repeat the measuring procedure for the
second vertical laser plane. For this, select
an operating mode in which a vertical laser
plane is generated aside of the tool. Turn the
tool 90° before beginning with the measuring
procedure.

Doubled height of the door opening x 0.004
in/ft

Example: For a door-opening height of 6.5ft,
the maximum deviation may be

2 x 6.5 ft x ±0.004 in/ft = ±1/16 in.
Consequently, points III and IV may be
no more than 1/16 in (max.) apart from
each other.

– Mark the centre of the upper crossing point

on the ceiling (point I). Also mark the centre
of the bottom laser point on the floor (point II).

d

180°

– Rotate the measuring tool 180°. Position it

so that the centre of the lower laser point
is on the point II which has already been
marked. Allow the measuring tool to level.

Mark the centre of the upper laser point

(point III).

– The difference d of both marked points I and

III on the ceiling results in the actual deviation
of the measuring tool to the plumb line.

The maximum permitted deviation dmax can
be calculated as follows:

MAX = double the distance between floor and

d
ceiling x 0.009 in/ft

Example: If the distance from the floor to the
ceiling is 5m, the maximum deviation is

MAX = 2 x 16 ft x 0.009 in/ft = 9/32 in. The

d
marks must therefore be maximum 9/32 in.

Working Advice

t For marking, always use only the center

of the laser point or the laser line. The

size of the laser point as well as the width of
the laser line change with distance.

t The measuring tool is equipped with

a radio interface. Local operating
restrictions, e.g. in airplanes or
hospitals, are to be observed.

Working with the Tripod

(Accessory)

A tripod offers a stable, height-adjustable
support surface for measuring. Place
the measuring tool with the 1/4” tripod
mount 12 on the thread of the tripod 27 or
a conventional camera tripod. Tighten the
measuring tool using the locking screw of the
tripod.

Adjust the tripod roughly before switching on
the measuring tool.

Fastening with the Universal Holder

(Accessory) (see figure G)

With the BM 1 positioning device 21, you can
fasten the measuring tool, e.g., to vertical
surfaces, pipes or magnetisable materials.
The universal holder is also suitable for use
as a ground tripod and makes the height
adjustment of the measuring tool easier.

Adjust the BM 1 positioning device 21 roughly
before switching on the measuring tool.

Working with the Laser Target Plate

(see figure G)

The laser target plate 24 increases the
visibility of the laser beam under unfavourable
conditions and at large distances.

The reflective part of the laser target plate 24
improves the visibility of the laser line. Thanks
to the transparent part, the laser line is also
visible from the back side of the laser target
plate.

Laser Viewing Glasses

(Accessory)

The laser viewing glasses filter out ambient
light. This enhances the laser visibility for the
eye.

t %POPU VTFUIFMBTFSWJFXJOH HMBTTFTBT
safety goggles. The laser viewing glasses

are used for improved visualization of the
laser beam, but they do not protect against
laser radiation.

t %POPUVTFUIF MBTFSWJFXJOHHMBTTFTBT
sun glasses or in traffic. The laser

viewing glasses do not afford complete UV
protection and reduce color perception.

Work Examples

(see figures B2–F2, G and H)

Applicational examples for the measuring tool
can be found on the graphics pages.

Always position the measuring tool close to
the surface or edge you want to check, and
allow it to level in prior to each measurement.
