Ex- treme fluctuations in temperature can cause deviations in accuracy. D) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected. The serial number (12) on the type plate is used to clearly identify your measuring tool. Assembly Inserting/Changing the batteries It is recommended that you use alkaline manganese batter- ies to operate the measuring tool. To open the battery compartment cover(6), press the lock- ing mechanism(7) and lift open the battery compartment cover. Insert the batteries. When inserting the batteries, ensure that the polarity is cor- rect according to the illustration on the inside of the battery compartment. 1 609 92A 8E9 | (20.03.2023) Bosch Power ToolsEnglish | 19 If the batteries become weak, the battery warning indicator(2) will flash green. The laser lines will also flash for approximately fiveseconds every tenminutes. The measur- ing tool can still be operated for approximately onehour after the first flash. If the batteries drain completely, the laser lines will flash one more time just before automatic shut-off. Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity. u Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The bat- teries can corrode and self-discharge during prolonged storage in the measuring tool. Working with the RM1rotating mount (seefiguresA1–A3) You can use the rotating mount(14) to rotate the measuring tool 360° around a central, always visible plumb point. This enables you to set up the laser lines without having to change the position of the measuring tool. Place the measuring tool with the guide groove(8) on the guide rail(15) of the rotating mount(14) and slide the measuring tool all the way onto the platform. To disconnect the measuring tool, pull it off the rotating mount in the opposite direction. Rotating mount positioning options: – Standing on a flat surface, – Screwed to a vertical surface, – On metallic ceiling strips using the ceiling clip(18), – On metallic surfaces using the magnets(17). u Keep your fingers away from the rear side of the mag- netic accessory while attaching the accessory to sur- faces. The strong pulling force of the magnets may jam your fingers. Operation Starting Operation u Protect the measuring tool from moisture and direct sunlight. u Do not expose the measuring tool to any extreme tem- peratures 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 temper- ature, 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", page21). The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature. u 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", page21). u 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(9) 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 beams from the outlet apertures(1). u 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 (9) to the Off position. The pendulum unit is locked when the tool is switched off. u 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. 120min, the measuring tool will automatically switch itself off to preserve battery life. To switch the measuring tool back on after it has been auto- matically switched off, you can either slide the on/off switch(9) to the "Off" position first and then switch the measuring tool back on, or press either the laser point mode button(4) or the laser line mode button(5). Temporarily Deactivating Automatic Shut-Off To deactivate the automatic shut-off function, hold down the laser line mode button(5) for at least 3s (with the measur- ing tool switched on). If the automatic shut-off function is deactivated, the laser beams will flash briefly as confirma- tion. 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 meas- uring tool off and on again. Setting the Operating Mode The measuring tool has several operating modes, which you can switch between at any time: – Cross-line and point mode: The measuring tool gener- ates a horizontal and a vertical laser line as well as two vertical laser points, one facing up, the other down. The laser lines cross at a 90° angle. – Horizontal line mode: The measuring tool generates a horizontal laser line in front of it. Bosch Power Tools 1 609 92A 8E9 | (20.03.2023)20 | English – Vertical line mode: The measuring tool generates a ver- tical laser line in front of it. Positioning the measuring tool in the room displays the vertical laser line on the ceiling beyond the top laser point. If the measuring tool is positioned directly against a wall, the vertical laser line almost encircles the entire space (360° line). – Point mode: The measuring tool generates two vertical laser points, one facing up, the other down. All operating modes, apart from point operation, can be se- lected with both automatic levelling or the pendulum lock.

If the measuring tool is outside of the self-levelling range, the laser lines and/or points will flash quickly. If, during work with automatic levelling, you switch to "work- ing with pendulum lock" mode (on/off switch(9) in position On), the first combination option of this mode's indicators is always activated.

Cross-line mode The laser lines continuously flash slowly in "working with the pendulum lock" mode. If, during work with pendulum lock, you switch to "working with automatic levelling" mode (on/off switch(9) in position On), the first combination option of this mode's indicat- ors is always activated. Automatic Levelling Working with Automatic Levelling (see figuresB1–E1) Position the measuring tool on a level, firm surface or attach it to the rotating mount(14). For work with automatic levelling, slide the on/off switch(9) to the " On" position. 1 609 92A 8E9 | (20.03.2023) Bosch Power ToolsEnglish | 21 The automatic levelling function automatically levels irregu- larities within the self-levelling range of ±4°. The measuring tool has been levelled as soon as the laser beams stop flash- ing. If automatic levelling is not possible, e.g. because the sur- face on which the measuring tool stands deviates by more than4°from the horizontal plane, the laser beams will flash quickly. If this is the case, set up the measuring tool in a level position and wait for the 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. In case of ground vibrations or position changes during oper- ation, the measuring tool is automatically levelled again. Upon levelling, check the position of the laser beams with re- gard to the reference points to avoid errors arising from a change in the measuring tool's position. Working with a pendulum lock (seefigureF1) For work with the pendulum lock, slide the on/off switch(9) 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, 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 beams 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. In order to minimise 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 measur- ing 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 height accuracy and levelling accuracy of the horizontal laser line, then the levelling accuracy of the ver- tical 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 5m on firm ground between two walls (designated A andB). – Mount the measuring tool close to wallA on a tripod, or place it on a firm, level surface. Switch on the measuring tool. Select cross-line mode with automatic levelling.

5 m – 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 (pointI).

180° – Turn the measuring tool 180°, allow it to level in and mark the point where the laser lines cross on the opposite wall B (pointⅡ). – Position the measuring tool –without rotating it– close to wallB, 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 pointⅡ on wallB.

Bosch Power Tools 1 609 92A 8E9 | (20.03.2023)22 | English– Turn the measuring tool 180° without adjusting theheight. Aim it at wallA such that the vertical laser line runsthrough the already marked pointⅠ. Allow the measuringtool to level in and mark the point where the laser linescross on wallA (pointⅢ).– The discrepancy d between the two marked pointsⅠ andⅢ on wallA reveals the actual height deviation of themeasuring tool.The maximum permitted deviation on the measuring dis-tance of 2×5m=10m is as follows: 10m×±0.3mm/m=±3mm. The discrepancy d between pointsⅠ and Ⅲ must therefore amount to no more than3mm.Checking the Level Accuracy of the Horizontal LineFor this check, you will need a free area of 5×5m.– Mount the measuring tool in the middle between wallsAand B on a tripod, or place it on a firm, level surface. Se-lect horizontal line mode with automatic levelling and al-low the measuring tool to level in. 2,5 m 5,0 m

– At a distance of 2.5m from the measuring tool, mark thecentre of the laser line on both walls (pointⅠ on wallA andpointⅡ on wallB). 2,5 m

5,0 m 2,5 m 5,0 m 0 m

– Set up the measuring tool at a 5m distance and rotatedby 180° and allow it to level in.– Align the height of the measuring tool (using the tripod orby placing objects underneath as required) so that thecentre of the laser line exactly hits the previously markedpointⅡ on wallB.– Mark the centre of the laser line on wallA as pointⅢ (ver-tically above or below pointⅠ).– The discrepancy d between the two marked pointsⅠ andⅢ on wallA reveals the actual horizontal deviation of themeasuring tool.The maximum permitted deviation on the measuring dis-tance of 2×5m=10m is as follows: 10m×±0.3mm/m=±3mm. The discrepancy d between pointsⅠ and Ⅲ must therefore amount to no more than3mm.Checking the Level Accuracy of the Vertical LineFor this check, you will need a door opening (on solidground) which has at least 2.5m of space either side of thedoor.– Place the measuring tool 2.5m away from the door open-ing on a firm, flat surface (not on a tripod). Select verticalline mode with automatic levelling. Aim the laser line atthe door opening and allow the measuring tool to level in. 2,5 m 2,5 m – Mark the centre of the vertical laser line on the floor of thedoor opening (pointⅠ), 5m away on the other side of thedoor opening (pointⅡ) and on the upper edge of the dooropening (pointⅢ).

2 m 1 609 92A 8E9 | (20.03.2023) Bosch Power ToolsEnglish | 23 – Rotate the measuring tool 180° and position it on the other side of the door opening, directly behind pointⅡ. Allow the measuring tool to level in and align the vertical laser line in such a way that its centre passes through pointsⅠ andⅡ exactly. – Mark the centre of the laser line on the upper edge of the door opening as pointⅣ. – The discrepancy d between the two marked pointsⅢ 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 fol- lows: Doubled height of the door opening×0.3mm/m Example: At a door opening height of 2m, the maximum de- viation amounts to 2×2m×±0.3mm/m=±1.2mm. The pointsⅢ and Ⅳ must therefore be no further than 1.2mm from each other. Checking Plumb Accuracy For this check, you will need a clear measuring space on firm ground with a distance of approx. 5m between the floor and the ceiling. – Mount the measuring tool onto the rotating mount(14) and place it on the floor. Select point mode and allow the measuring tool to level in. 5 m – Mark the centre of the top laser point on the ceiling (pointI). Also mark the centre of the bottom laser point on the floor (pointII).
