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 unrecognisable. 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.
Keep the magnetic accessories away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnets in the accessories generate a field that can impair the function of implants and medical devices.
Keep the magnetic accessories away from magnetic data storage media and magnetically-sensitive devices. The effect of the magnets in the accessories can lead to irreversible data loss.

Assembly

Inserting/Changing the batteries
It is recommended that you use alkaline manganese batteries to operate the measuring tool.
Press the locking mechanism (6) upwards to open the battery compartment cover (7) and remove the battery compartment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.
The battery indicator (2) always indicates the current status of the battery.
If the batteries are running low, the laser lines will gradually become dimmer.
If the batteries are almost empty, the battery indicator (2) will flash continuously. The laser lines will flash for 5 seconds every 5 minutes.
If the batteries are empty, the laser lines and the battery indicator will flash once before the measuring tool switches off.
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.

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 ambi-ent temperature and then always carry out an accuracy check before continuing work (see “Accuracy Check of the Measuring Tool”, page 15).
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 15).
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 (4) to the “On” position. As soon as it is switched on, the measuring tool emits laser beams 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 (4) 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 50 °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.
Automatic shut-off
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 (4) to the “Off” position first and then switch the measuring tool back on, or press the laser operating mode button (3).
To deactivate the automatic shut-off function, hold down the laser mode button (3) 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.
Note: If the operating temperature exceeds 45 °C, automatic shut-off can no longer be deactivated.
To activate the automatic shut-off function, switch the measuring tool off and on again.
Operating Modes
The measuring tool has several operating modes, which you can switch between at any time:
– Cross-line mode (see figure A): Generates one horizontal and one vertical laser line
– Horizontal mode (see figure B): Generates one horizontal laser line
– Vertical mode (see figure C): Generates one vertical laser line
To change the operating mode, press the button for laser operating mode (3) as often as required until the laser beams are generated in the required operating mode.
All operating modes can be used with both automatic levelling and the incline function.
Automatic Levelling
The measuring tool monitors the position at all times during operation. It works with automatic levelling during set-up within the self-levelling range of ±4°. Outside of the self-levelling range, it will automatically switch to the incline function.
Working with automatic levelling (see figures A–C) Position the measuring tool on a level, firm surface or attach it to the holder (10) or the tripod (15).
The automatic levelling function automatically compensates irregularities within the self-levelling range of ±4°. Once the laser beam is permanently lit, the measuring tool has levelled in.
If automatic levelling 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 will initially flash quickly for 2 seconds, then quickly flash every 5 seconds several times. The measuring tool is in the incline function.
For additional work with automatic levelling, set up the measuring tool so that it is horizontal and wait for the selflevelling procedure to complete. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams will light up continuously.
In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again.
Upon levelling, check the position of the laser beams with regard to the reference points to avoid errors arising from a change in the measuring tool’s position.
Working with the Incline Function (see figure D)
Place the measuring tool on an inclined surface. When working with the incline function, the laser lines will initially flash quickly for 2 seconds, then quickly flash every 5 seconds several times.
In the incline function, the laser lines are no longer levelled and no longer necessarily run perpendicular to one another.

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.
Since the temperature stratification is greatest at ground level, you should mount the measuring tool on a tripod and position it 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 height accuracy and levelling accuracy of the horizontal laser line, then the levelling accuracy of the vertical laser line.
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 Height Accuracy of the Horizontal Line 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, level surface. Switch on the measuring tool and select cross-line operation.– 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 previously 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 × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must therefore amount to no more than 3 mm.
Checking the Level Accuracy of the Horizontal Line
For this check, you will need a free area of 5 × 5 m.
– Mount the measuring tool in the middle between walls A and B on a tripod, or place it on a firm, level surface.
Switch on the measuring tool and select horizontal operation. Allow the measuring tool to level in. – At a distance of 2.5 m from the measuring tool, mark the centre of the laser line on both walls (point Ⅰ on wall A and point Ⅱ on wall B). – Set up the measuring tool at a 5 m distance and rotated by 180° 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 centre of the laser line exactly hits the previously marked point Ⅱ on wall B.
– Mark the centre of the laser line on wall A as point Ⅲ (vertically above or below point Ⅰ).
– The discrepancy d between the two marked points Ⅰ and Ⅲ on wall A reveals the actual horizontal deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows:
10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must therefore amount to no more than 3 mm.
Checking the Level Accuracy of the Vertical Line
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 and select vertical operation. Aim the laser line at the door opening and allow the measuring tool to level in. – 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.
You can calculate the maximum permitted deviation as follows:
Doubled height of the door opening × 0.3 mm/m Example: At a door opening height of 2 m, the maximum deviation amounts to 2 × 2 m × ±0.3 mm/m = ±1.2 mm. The points Ⅲ and Ⅳ must therefore be no further than 1.2 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 holder LB 10 (see figures E−H)
You can secure the measuring tool on vertical surfaces or magnetisable materials using the holder (10). In conjunction with the ceiling clip (14), the measuring tool can also be aligned vertically.
Place the measuring tool with the 1/4″ tripod mount (5) on the 1/4″ screw (11) of the holder and screw it tight.
Attachment Options for the Holder (10):
– Using a commercially available fastening screw, it can be attached via the screw hole (13) to drywall or wood (see figure F)
– Using the magnets (12), it can be attached to metallic surfaces (see figure G)
– Using the ceiling clip (14), it can be attached to crown mouldings (see figure H)
Roughly align the holder (10) before switching on the measuring tool.
Working with the Laser Target Plate
The laser target plate (20) improves visibility of the laser beam in unfavourable conditions and at greater distances.
The reflective half of the laser target plate (20) improves visibility of the laser line. The transparent half 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 (5) on the thread of the tripod (15) or a conventional camera tripod. Tighten the measuring tool using the locking screw of the tripod.
Roughly align the tripod before switching on the measuring tool.
Securing with the universal holder (accessory) (see figure K)
Using the universal holder (17), you can secure the measuring tool on vertical surfaces, pipes or magnetizable materials, for example. The universal holder is also suitable for use as a building tripod and facilitates height adjustment of the measuring tool.
Roughly align the universal holder (17) before switching on the measuring tool.
Working with the rotating mount (accessory)
Using the rotating mount (18), you can rotate the measuring tool 360°. This enables you to set up the laser lines precisely, without having to change the position of the measuring tool.
You can use the rotating mount (18) as a floor stand or to attach the measuring tool to vertical surfaces; alternatively, the measuring tool can be attached to metallic surfaces by means of the magnets (12) or to crown mouldings in conjunction with the ceiling clip (14).
Roughly align the rotating mount (18) before switching on the measuring tool.
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 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 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 I–K)
Examples of possible applications for the measuring tool can be found on the graphics pages.
