Please observe the article number on the type plate of your tool.

The trade names of the individual tools may vary.

The tool can be clearly identified with the serial number 12 on

the type plate.

Initial Operation

• Protect the tool against moisture.

• Do not subject the tool to extreme temperatures or

variations in temperature.

As an example, do not leave it in vehicles for longer periods. I

in case of large variations in temperature, allow the tool to

adjust to the ambient temperature before putting it into

operation. In case of extreme temperatures or variations in

temperature, the accuracy of the tool canbe impaired.

Setting Up the Tool (see figure A)

Position the tool at least 17ft (5m) away from the cross-line

laser. Switch on the pulsating function on the cross-line laser,

and select horizontal or vertical operation.

Note: Do not select cross-line operation, as otherwise faulty

indications on the height of the laser beam can occur.

Position the tool in such a manner that the laser beam can

reach the reception area 6. Align the tool in such a manner that

the laser beam runs laterally through the reception area (as

shown in the figure).

Switching On and Off

• A loud audio signal sounds when switching on the tool.

Therefore, keep the tool away from your ear or other person

when switching on. The loud audio signal can cause

hearing defects.

To switch on the tool, press the On/Off button 2. All display

indicators as well as all LEDs light up briefly and an audio

signal sounds.

To switch off the tool, press the On/Off button 2again. Before

switching off, all LEDs briefly light up.

Operation

www. .com information@itm.com1.800.561.8187

When no button is pressed on the tool for approx. 20 minutes

and when no laser beam reaches the reception area 6for 20

minutes, the tool automatically switches off in order to save the

battery. The switching off is indicated by brief lighting up of

all LEDs.

Selecting the Setting of the Center Indicator

With button 1, you can specify with which accuracy the position

of the laser beam is indicated as central on the reception area:

– “Fine” adjustment (indication gon the display),

– “Medium” adjustment (indication fon the display).

Whenever switching on the tool, the accuracy level “Medium”

is set.

Direction Indicators

The position of the laser beam on the reception area 6

is indicated:

– via the direction indicators “move downward” d, “move

upward” b or the center indicator c on the display 4on the

front and back side of the tool,

– via the LEDs “move downward” 8, “move upward” 10 or the

center-indication LED 9on the front side of the tool,

– optionally via the audio signal (see “Audio Signal for

Indication of the Laser Beam”).

Tool too low: When the laser beam runs through the top half of the

reception area 6, the direction indicator b on the display and the

corresponding direction LED 10 light up. When the audio signal is

switched on, a slow-beat signal sounds. Move the tool upward in the

direction of the arrow.

Tool too high: When the laser beam runs through the bottom half of

the reception area 6, the direction indicator d on the display and the

corresponding direction LED 8light up.

When the audio signal is switched on, a fast-beat signal sounds.

Move the tool downward in the direction of the arrow.

Tool in center position: When the laser beam runs through the

reception area 6at the center mark 7, the centre indicator c on the

display and the corresponding center-indication LED 9light up.

When the audio signal is switched on, a continuous signal sounds.

Audio Signal for Indication of the Laser Beam

The position of the laser beam on the reception area 6can be

indicated via an audio signal.

After the tool has been switched on, the audio signal is always set to

the low volume level.

The volume level can be increased or switched off.

-10-

www. .com information@itm.com1.800.561.8187

To change the volume level or switch off the audio signal, push the

acoustic signal button 3until the requested volume level is indicated

on the display. At low volume level, the audio signal indicator a

appears on the display with one bar; at high volume level, the

indicator appears with three bars. When the audio signal is set to off,

the indicator goes out.

Independent of the audio signal setting, a short beep sounds at low

volume level each time a button is pressed on the tool.

Working Advice

Marking

When the laser beam runs through the center of the reception area

6, its height can be marked at the center mark 7right and left on

the tool.

When marking, take care to align the tool exactly vertical (for

horizontal laser beam), or horizontal (for vertical laser beam), as

otherwise the marks are offset with respect to the laser beam.

Attaching with the Magnet (see figure B)

When a positive-lock attachment is not absolutely required, the tool

can be attached to steel parts via the face side using the magnet

plate 5.

Keep the tool clean at all times.

Do not immerse the tool into water or other fluids.

Wipe off debris using a moist and soft cloth. Do not use any

cleaning agents or solvents.

If the tool should fail despite the care taken in manufacturing

and testing procedures, repair should be carried out by an

authorized after- sales service center for Bosch power tools.

In all correspondence and spare parts orders, please always

include the 10-digit article number given on the type plate of

the tool.
