Assembly

Measuring tool 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: The use of battery packs not suitable for the measuring tool can lead to malfunctions or cause damage to the measuring tool.
Note: The battery pack is supplied partially charged. To ensure the 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 battery of your measuring tool. The lithium-ion battery pack can be charged at any time without reducing its service life. Interrupting the charging procedure 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 15, slide it into the battery port until you feel it engage. To remove the battery pack 15, press the unlocking buttons 13 and pull the battery pack out of the battery port 10. Do not use force to do this.

Operation with Batteries
Alkali-manganese batteries are recommended for the measuring tool. 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 11 of the battery adapter into the battery port 10. Place the batteries in the cover as shown in the illustration on the sealing cap 14. Slide the sealing cap over the cover until you feel it click into place. To remove the batteries 12 press the unlocking buttons 13 of the sealing cap 14 and pull off the sealing cap. Make sure that the batteries do not fall out. To do so, hold the measuring tool with the battery port 10 facing upward. Remove the batteries. To remove the inside cover 11 from the battery port 10, 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 batteries from one brand and with an identical capacity.
Remove the batteries from the measuring tool when not using it for extended periods. When stored for extended periods, the batteries can corrode and self-discharge.
Battery Status Indicator
The battery status indicator 2 shows the charge condition of the battery pack or batteries:

LED	Charge Condition
Continuous lighting, green	100–75 %
Continuous lighting, yellow	75–35 %
Continuous lighting, red	35–10 %
No light	– Battery pack defective

– Batteries empty

If the battery pack or the batteries are running low, the laser lines will gradually become dimmer.
Immediately replace a faulted battery pack or empty batteries.

Operation

Initial Operation

Protect the measuring tool against moisture and direct sunlight.
Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations 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 temperature, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool. After severe exterior effects on the measuring tool, it is recommended to carry out an accuracy check (see “Accuracy Check of the Measuring Tool”, page 21) each time before continuing to work.
Switch the measuring tool off during transport. When switching off, the leveling 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 16to the “On” position (when working without automatic leveling) or to the “On” position (when working with automatic leveling). Immediately after switching on, the measuring tool sends laser beams out of the exit openings 1.

Do not point the laser beam at persons or animals and do not look into the laser beam yourself, not even from a large distance. To switch off the measuring tool, slide the On/Off switch 16 to the “Off” position. When switching off, the leveling unit is locked.
Do not leave the switched-on measuring tool unattended and switch the measuring tool off after use. Other persons could be blinded by the laser beam. When exceeding the maximum permitted operating temperature of 40 °C, the measuring tool switches off to protect the laser diode. After cooling down, the measuring tool is ready for operation and can be switched on again. If the temperature of the measuring tool is approaching the maximum permissible operating temperature, the laser lines will gradually become dimmer.

Deactivating the Automatic Shut-off
When no button on the measuring tool is pressed for approx. 120 minutes, the measuring tool automatically switches off to save the batteries. To switch the measuring tool back on after automatic shut-off, you can either slide the On/Off switch 16 to the “Off” position first and then switch the measuring tool back on, or press either the laser mode button 7 or the receiver mode button 5 once. To deactivate the automatic shut-off function, hold down the laser mode button 7 for at least 3 s (with the measuring tool switched on). If the automatic shut-off function is deactivated, the laser beams will flash briefly as confirmation. To activate the automatic shut-off, switch the measuring tool off and then on again.

Deactivating the Signal Tone
After the measuring tool has been switched on, the audio signal is always activated. To deactivate or activate the audio signal, simultaneously press the laser mode button 7 and the receiver mode button 5 and hold them down for at least 3 s.
The audio signal activation and deactivation are both confirmed by three short beeps.

Operating Modes
The measuring tool has several operating modes which you can switch at any time. These are for:
– Generating a horizontal laser plane,
– Generating a vertical laser plane,
–Generating two vertical laser planes,
– Generating a horizontal laser plane as well as two vertical laser planes.
After you switch it on, the measuring tool generates a horizontal laser plane. To change the operating mode, press the laser mode button 7.
All operating modes can be selected both with and without automatic leveling.

Receiver mode
Receiver mode must be activated to work with the laser receiver 26
– regardless of which operating mode is selected.
In receiver mode the laser lines flash at a very high frequency, enabling them to be detected by the laser receiver 26.
To switch on receiver mode, press button 5. Indicator 6 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 5 again to work without a laser receiver. Indicator 6 will extinguish.

Automatic Levelling
Working with Automatic Levelling
Position the measuring tool on a level and firm support, and attach it to the holder 24 or to the tripod 30. When working with automatic leveling, push the On/Off switch 16 to the “ On” position.
After switching on, the leveling function automatically compensates for irregularities within the self-leveling range of ±4°. The leveling is finished as soon as the laser beams do not move anymore.

If automatic leveling 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 lines begin to flash rapidly. When the audio signal is activated, a fast-beat signal sounds. Set up the measuring tool in a level position and wait for the self-leveling to take place. As soon as the measuring tool is within the self-leveling range of ±4°, all laser beams light up continuously and the audio signal is switched off. In case of ground vibrations or position changes during operation, the measuring tool is automatically leveled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon re-leveling.

Working without Automatic Levelling
For work without automatic leveling, slide the on/off switch 16 to the “On” position. When automatic leveling is switched off, indicator 4 lights up red and the laser lines
continuously flash slowly. When automatic leveling is switched off, you can hold the measuring tool freely in your hand or place it on an inclined surface. The laser lines no longer necessarily run perpendicular to each other.

Remote control via the “Levelling Remote App”
The measuring tool is equipped with a Bluetooth® module that uses radio technology to enable remote control via a smartphone with a Bluetooth® interface.
The “Levelling Remote App” application (app) is needed to use this function. You can download this in the app store for your terminal device (Apple App Store, Google Play store). For information on the necessary system requirements for a Bluetooth® connection, please refer to the Bosch website at www.bosch-pt.com
When remote controlling by means of Bluetooth®, time lags may occur between the mobile terminal/device and measuring tool as a result of poor reception conditions.

Switching On Bluetooth®
To switch on Bluetooth ® for the remote control, press the Bluetooth ®-button 9. Ensure that the Bluetooth ® interface is activated on your mobile terminal/device. After starting the Bosch application, the connection between the mobile terminal/device and the measuring tool is established. When several active measuring tools are found, select the appropriate measuring tool. When only one active measuring tool is found, the connection is automatically established. The connection is established as soon as the Bluetooth ® indicator 8 lights up. The Bluetooth ® connection may be interrupted if there is too much distance or there are obstacles between the measuring tool and mobile terminal/device and if there are any electromagnetic interference sources. In this case, the Bluetooth ® indicator flashes.

Switching Off Bluetooth®
To switch off Bluetooth® for the remote control, press the Bluetooth® button 9 or switch off the measuring tool.

CAL guard calibration warning
The CAL guard calibration warning sensors monitor the status of the measuring tool, even when it is switched off. If the measuring tool is not being supplied with power by a battery pack or batteries, an internal energy storage battery provides continuous monitoring by the sensors for 72 hours. The sensors are activated when the measuring tool is started up for the first time.

Calibration warning triggers
If one of the following events occurs, the CAL guard calibration warning is triggered and indicator 3 lights up red:
– The calibration interval (every 12 months) has expired.
– The measuring tool was stored outside of the storage temperature range.
– The measuring tool suffered a severe shock (e.g. impact on the floor after a fall). You can refer to the “Levelling Remote App” to see which of the three events triggered the calibration warning. Without the app, the cause cannot be identified as the CAL guard indicator, the CAL guard indicator 3 lighting up indicates merely that the leveling accuracy needs to be checked. Once the warning has been triggered, the CAL guard indicator 3 lights up until the leveling accuracy have been checked and the indicator switched off.

Procedure in the event of a calibration warning being triggered
Check the leveling accuracy of the measuring tool (see “Accuracy Check of the Measuring Tool”, page 21).
If the maximum deviation has not been exceeded in any of the tests, switch the CAL guard indicator 3 off. To do so, press and hold the receiver mode button 5 and the Bluetooth® button 9 at the same time for at least 3s. The CAL guard indicator 3 goes out. Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service.

Accuracy Check of the Measuring 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 measuring tool should always be mounted on a tripod when measuring distances exceeding 20 m. If possible, also set up the measuring tool in the center of the work area. In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the leveling accuracy each time before beginning work. Firstly, check the leveling accuracy of the horizontal laser line and then the leveling accuracy of the vertical laser lines. Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service.

Checking the Horizontal Levelling Accuracy of the Lateral Axis
For this check, a free measuring distance of 5 m on a firm surface between two walls A and B is required.
– Mount the measuring tool onto a tripod, or place it on a firm and level surface close to wall A. Switch on the measuring tool to operate with automatic leveling. Select the operating mode in which a horizontal laser plane, as well as a vertical laser plane in front of the measuring tool, are generated.

– Direct the laser against the close wall A and allow the measuring tool to level in. Mark the center of the point where the laser lines cross each other at wall A (point I).
– Turn the measuring 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 measuring tool, position it close to wall B. Switch the measuring tool on and allow it to level in.
– Align the height of the measuring 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 wall B.
– Without changing the height, turn around the measuring tool by 180°. Direct it against wall A in such a manner that the vertical laser line runs through the already marked point I. Allow the measuring tool to level in and mark the cross point of the laser lines on wall A (point III).
–The difference d of both marked points I and III on the wall A results in the actual height deviation of the measuring tool alongside the lateral axis.
On the measuring distance of 2 x 5 m = 10 m, the maximum allowable deviation is: 10mx±0.2mm/m=±2mm. Thus, the difference d between points I and III must not exceed
2 mm (max.).

Checking the Levelling Accuracy of the Vertical Lines
For this check, a door opening is required with at least 2.5 m of space (on a firm surface) to each side of the door.
– Position the measuring tool on a firm, level surface (not on a tripod) 2.5 m away from the door opening. Switch on the measuring tool to operate with automatic leveling. Select an operating mode in which a vertical laser plane is generated in front of the measuring tool.

– Mark the center of the vertical laser line at the floor of the door opening (a point I), at a distance of 5 m beyond the other side of the door opening (point II), and at the upper
edge of the door opening (point III).

– Rotate the measuring tool by 180° and position it on the other side of the door opening directly behind point II. Allow the measuring 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 measuring tool to the plumb line.
– Measure the height of the door opening.
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 measuring tool, and turn the measuring tool by 90° before beginning with the measuring procedure. The maximum admissible deviation is calculated as follows:
Doubled height of the door opening x 0.2 mm/m
Example: For a door-opening height of 2 m, the maximum deviation maybe 2 x 2 m x ±0.2 mm/m = ±0.8 mm. Consequently, points III and IV may be no more than 0.8 mm (max.) apart from each other for each of both measurements.

Working Advice

Always use the center of the laser line for marking. The width of the laser line changes with the distance.
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 Laser Target Plate
The laser target plate 27 increases the visibility of the laser beam under unfavorable conditions and at large distances. The reflective part of the laser target plate 27 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.

Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable measuring support. Position the measuring tool with the 1/4″ tripod mount 17 onto the thread of the tripod 30 or a commercially available camera tripod. For fastening to a commercially available construction tripod, use the 5/8″ tripod mount 18. Tighten the measuring tool with the tripod mounting stud. Adjust the tripod roughly before switching on the measuring tool.

Fastening with the Universal Holder (Accessory) (see figure B)
With the universal holder 24, you can fasten the measuring tool, e.g., to vertical surfaces, pipes, or magnetizable 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 universal holder roughly before 24 switching on the measuring tool.

Working with the Laser Receiver (Accessory) (see figure B)
Use the laser receiver 26 to improve detection of the laser lines in adverse lighting conditions (bright environment, direct sunlight) and over greater distances. Switch on receiver mode when working with the laser receiver (see “Receiver mode”, page 20).

Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out ambient light. This enhances the laser visibility for the eye.

Do not use the laser viewing glasses as safety goggles.
The laser viewing glasses are used for improved visualization of the laser beam, but they do not protect against laser radiation.
Do not use the laser viewing glasses as sunglasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce color perception.

Work Examples (see figures A–F)
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.
