Safety Instructions

All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions. Never make warning signs on the measuring tool unrecognizable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN TRANSFERRING IT TO A THIRD PARTY.

Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.
The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).
If the text of the laser warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.
Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody, cause accidents or damage your eyes.
If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.
Do not make any modifications to the laser equipment.
Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
Have the measuring tool serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the measuring tool is maintained.
Do not let children use the laser measuring tool unsupervised. They could unintentionally blind themselves or other persons.
Do not use the measuring tool in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the measuring tool, which can ignite dust or fumes.
Do not open the battery. There is a risk of short-circuiting.
In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
If used incorrectly or if the battery is damaged, flammable liquid may be ejected from the battery. Contact with this liquid should be avoided. If contact accident-ally occurs, rinse off with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid ejected from the battery may cause irritation or burns.
The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
When the battery is not in use, keep it away from pa-per clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire.
Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.
Only charge the batteries using chargers recommended by the manufacturer. A charger that is suitable for one type of battery may pose a fire risk when used with a different battery.
Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short- circuiting.
Remove the rechargeable battery/non-rechargeable batteries from the measuring tool before carrying out work on the measuring tool (e.g. assembly, maintenance, etc.). The battery/batteries should also be re-moved for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
When operating the measuring tool, loud signal tones may sound under certain circumstances. For this reason, keep the measuring tool away from your ears and from other persons. The loud sound can damage hearing.
Keep the measuring tool and the magnetic accessories away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnets inside the measuring tool and accessories generate a field that can impair the function of implants and medical devices.
Keep the measuring tool and the magnetic accessor-ies away from magnetic data storage media and magnetically sensitive devices. The effect of the magnets in-side the measuring tool and accessories can lead to irreversible data loss.
The measuring tool is equipped with a wireless inter-face. Local operating restrictions, e.g. in aero planes or hospitals, must be observed.
The Bluetooth® word mark and logos are registered trade-marks owned by Bluetooth SIG, Inc. and any use of such marks by Robert Bosch Power Tools GmbH is under li-cense.
Caution! When using the measuring tool with Bluetooth®, a fault may occur in other devices and systems, aero planes and medical devices (e.g. pace-makers, hearing aids). Also, damage to people and animals in the immediate vicinity cannot be completely excluded. Do not use the measuring tool with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas with a potentially ex-plosive atmosphere and in blasting areas. Do not use the measuring tool with Bluetooth® on aero planes. Avoid using the product near your body for extended periods.

Assembly

Measuring Tool Power Supply
The measuring tool can be operated either with conventional non-rechargeable batteries or with a Bosch lithium-ion battery.
Operation with Rechargeable Battery

Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your measuring tool.

Note: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before using your tool for the first time.
To insert the charged battery (14), slide it into the battery bay (9) until you feel it engage.
To remove the battery (14), press the release buttons (12) and pull it out of the battery bay (9). 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 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 bay (9). Place the batteries into the cover as per 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 (11), press the re-lease buttons (12) of the sealing cap (13) and pull off the sealing cap. Make sure that the batteries do not fall out. To do this, hold the measuring tool with the battery bay (9) facing up-ward. Remove the batteries. To remove the cover (10) 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 are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the measuring tool.

Battery Charge Indicator
The battery charge indicator (2) shows the state of charge of the battery/batteries:

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.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight.
Do not expose the measuring tool to any extreme temperatures 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 temperature, first allow the measuring tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work (see “Accuracy Check of the Measuring Tool”, page 11).
The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see “Accuracy Check of the Measuring Tool”, page 11).
Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements.

Switching On/Off
To switch on the measuring tool, slide the on/off
switch (15) to the ” On” position (for working with the pendulum lock) or to the ” On” position (for working with automatic levelling). As soon as it is switched on, the measuring tool emits laser lines from the outlet apertures (1).

Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance). To switch off the measuring tool, slide the on/off switch (15) to the Off position. The pendulum unit is locked when the tool is switched off.
Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.

If the maximum permitted operating temperature of 40 °C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is operational again and can be switched back on.
If the temperature of the measuring tool is approaching the maximum permissible operating temperature, the laser lines will gradually become dimmer.
The measuring tool is protected against electrostatic dis-charge (ESD). If the measuring tool becomes electrostatic-ally charged (e.g. when it is touched in an environment with low humidity), it switches itself off automatically. In such cases, switch the on/off switch (15) off and on again.

Deactivating the Automatic Shut-Off Function
If no button on the measuring tool is pressed for approx. 120 min, the measuring tool will automatically switch itself off to preserve battery life.
To switch the measuring tool back on after it has been automatically switched off, you can either slide the on/off switch (15) to the “Off” position first and then switch the measuring tool back on, or press either the laser mode button (6) or the receiver mode button (4) once. To deactivate the automatic shut-off function, hold down the laser mode button (6) 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 function, switch the measuring tool off and on again.

Deactivating the Signal Tone Function
The signal tone function is always activated once the measuring tool is switched on.
To deactivate or activate the signal tone function, simultaneously press the laser mode button (6) and the receiver mode button (4) and hold them down for at least 3 s. Three short signal tones will sound as confirmation both when the signal tone function is activated and deactivated.

Operating Modes

The measuring tool has several operating modes which you can switch between 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 and two vertical laser planes.

After you switch it on, the measuring tool generates a hori-zontal laser plane. To change the operating mode, press the laser mode button (6).
All operating modes can be selected with both automatic lev-elling or the pendulum lock.
Receiver Mode
Receiver mode must be activated when working with the laser receiver (25), regardless of which operating mode is selected.
In receiver mode, the laser lines flash at a very high fre-quency, enabling them to be detected by the laser receiver (25).
To switch on receiver mode, press the receiver mode button (4). The receiver mode indicator (5) will light up green. When receiver mode is switched on, the laser lines are less visible to the human eye. Therefore, switch receiver mode off by pressing the receiver mode button (4) again to work without a laser receiver. The receiver mode indicator (5) will go out.

Automatic Levelling

Working with Automatic Levelling
Position the measuring tool on a level, firm surface or attach it to the universal holder (21) or the tripod (28).
For work with automatic levelling, slide the on/off switch (15) to the ” On” position. The automatic levelling function automatically compensates irregularities within the self-levelling range of ±4°. The level-ling is finished as soon as the laser lines stop moving. If automatic levelling is not possible, e.g. because the sur-face on which the measuring tool stands deviates by more than 4° from the horizontal plane, the laser lines will begin to flash quickly. If the signal tone function is activated, rapid signal tones will sound.
Place the measuring tool in a horizontal position and wait for self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams will light up continuously and the signal tones will cease.
In case of ground vibrations or position changes during oper-ation, the measuring tool is automatically levelled again. Upon re-levelling, check the position of the horizontal or ver-tical laser line with regard to the reference points to avoid er-rors by moving the measuring tool.
Working with the Pendulum Lock
For work with the pendulum lock, slide the on/off
switch (15) to the ” On” position. The pendulum lock indicator (3) lights up red and the laser lines continuously flash slowly.
For work with the pendulum lock, the automatic levelling is switched off. You can hold the measuring tool freely in your hand or place it on a sloping surface. This means that the laser lines are no longer levelled and no longer necessarily run perpendicular to one another.
Remote control via the Bosch Levelling Remote App
The measuring tool is equipped with a Bluetooth® module which uses radio technology to enable remote control via a smartphone with a Bluetooth® interface.
The Bosch Levelling Remote App application (app) is required to use this function. You can download this in the app store for your terminal device (Apple App Store, Google Play Store).
Information about the system requirements for a Bluetooth® connection can be found on the Bosch website at
www.bosch‑pt.com
When remote controlling via Bluetooth®, poor reception conditions can cause time delays between the mobile terminal device and the measuring tool.

Switching on Bluetooth®
To switch on Bluetooth®, press the Bluetooth® button (8). Ensure that the Bluetooth® interface is activated on your mobile terminal device.
The connection between mobile end device and measuring tool is established after the Bosch application has started. If multiple active measuring tools are found, select the appropriate measuring tool. A connection will be established automatically if only one active measuring tool is found.
The connection is established as soon as the Bluetooth® indicator (7) lights up.
The Bluetooth® connection may be interrupted if the distance between the measuring tool and the mobile terminal device is too great or is blocked, and if there are any sources of electromagnetic interference. Should this occur, the Bluetooth® indicator (7) will flash.

Switching off Bluetooth®
To switch off Bluetooth® for remote control, press the Bluetooth® button (8) or switch off the measuring tool.

Accuracy Check of the Measuring Tool

Influences on Accuracy
The largest influence is exerted by the ambient temperature. In particular, temperature differences that occur from the ground upwards can refract the laser beam.
In order to minimize thermal influences resulting from heat rising from the floor, it is recommended that you use the measuring tool on a tripod. In addition, position the measuring tool in the centre of the work surface, wherever this is possible.
In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the levelling accuracy each time before beginning work.
First check the levelling accuracy of the horizontal laser line, then the levelling 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 Transverse Axis
For this check, you will need a free measuring distance of 5 m on firm ground between two walls (designated A and B).

Mount the measuring tool close to wall A on a tripod, or place it on a firm, flat surface. Switch on the measuring tool in the mode with automatic levelling. Select the operating mode for generating a horizontal laser plane and a vertical laser plane directly in front of the measuring tool.
Aim the laser at the closer wall A and allow the measuring tool to level in. Mark the middle of the point at which the laser lines cross on the wall (point I).
Turn the measuring tool 180°, allow it to level in and mark the point where the laser lines cross on the opposite wall B (point Ⅱ).
Position the measuring tool – without rotating it – close to wall B, switch it on and allow it to level in.
– Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the point where the laser lines cross exactly hits the previ-ously marked point Ⅱ on wall B.
Turn the measuring tool 180° without adjusting the height. Aim it at wall A such that the vertical laser line runs through the already marked point Ⅰ. Allow the measuring tool to level in and mark the point where the laser lines cross on wall A (point Ⅲ).
The discrepancy d between the two marked points Ⅰ and Ⅲ on wall A reveals the actual height deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows:
10 m × ±0.2 mm/m = ±2 mm. The discrepancy d between points Ⅰ and Ⅱ must therefore amount to no more than 2 mm.

Checking the Levelling Accuracy of the Vertical Lines
For this check, you will need a door opening (on solid ground) which has at least 2.5 m of space either side of the door.

Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not on a tripod). Switch on the measuring tool in the mode with automatic levelling. Select the operating mode for generating a vertical laser plane directly in front of the measuring tool.
Mark the centre of the vertical laser line on the floor of the door opening (point Ⅰ), 5 m away on the other side of the door opening (point Ⅱ) and on the upper edge of the door opening (point Ⅲ).
Rotate the measuring tool 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 way that its centre passes through points Ⅰ and Ⅱ exactly.
Mark the centre of the laser line on the upper edge of the door opening as point Ⅳ.
The discrepancy d between the two marked points Ⅲ and Ⅳ reveals the actual vertical deviation of the measuring tool.
Measure the height of the door opening.
Repeat the measuring process for the two vertical laser planes. To do this, select the operating mode for generating a vertical laser plane to one side of the measuring tool and rotate the measuring tool by 90° before beginning the measuring process.
You can calculate the maximum permitted deviation as follows:
Doubled height of the door opening × 0.2 mm/m Example: At a door opening height of 2 m, the maximum deviation amounts to
2 × 2 m × ±0.2 mm/m = ±0.8 mm. The points Ⅲ and Ⅳ must therefore be no further than 0.8 mm from each other.

Working Advice

Only the centre of the laser line must be used for marking. The width of the laser line changes depending on the distance.

Working with the Laser Target Plate
The laser target plate (24) improves visibility of the laser beam in unfavorable conditions and at greater distances. The reflective surface of the laser target plate (24) improves visibility of the laser line. The transparent surface enables the laser line to be seen from behind the laser target plate.

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 (16) on the thread of the tripod (28) or a conventional camera tripod. Use the 5/8″ tripod mount (17) to se-cure the measuring tool on a conventional building tripod. Tighten the measuring tool using the locking screw of the tri-pod. Roughly align the tripod before switching on the measuring tool.

Securing with the universal holder (accessory) (see figure B)
You can secure the measuring tool, for example, on vertical surfaces or magnetizable materials using the universal holder (21). The universal holder is also suitable for use as a floor stand and facilitates the height adjustment of the measuring tool.

Keep your fingers away from the rear side of the magnetic accessory while attaching the accessory to sur-faces. The strong pulling force of the magnets may jam your fingers.

Roughly align the universal holder (21) before switching on the measuring tool.

Working with the laser receiver (accessory) (see figure B)
Use the laser receiver (25) to improve detection of the laser lines in adverse lighting conditions (bright environment, dir-ect sunlight) and over greater distances. When working with the laser receiver, switch on receiver mode (see “Receiver Mode”, page 10).

Laser Goggles (Accessory)
The laser goggles filter out ambient light. This makes the light of the laser appear brighter to the eye.

Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.

Example applications (see figures A–F)
Examples of possible applications for the measuring tool can be found on the graphics pages.
