At 20–25°C C) The values stated presuppose normal to favourable environmental conditions (e.g. no vibration, no fog, no smoke, no direct sunlight). Extreme 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 (9) 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 batteries to operate the measuring tool. If required, turn the magnetic rotating mount(3) to the side so that the battery compart- ment cover(6) is not obstructed. 1 609 92A 7S8 | (17.05.2022) Bosch Power ToolsEnglish | 23 Press the locking mechanism (5) upwards to open the battery compartment cover (6) and remove the battery compartment cover. Insert the batteries. When inserting the batteries, ensure that the polarity is correct according to the illustra- tion on the inside of the battery compartment. Reattach the battery compartment cover(6) and press it firmly into place at the marked point above the locking mechanism(5). If the batteries are running low, the laser points will gradually become dimmer. If the batteries are almost empty, the laser points will flash 5 times every minute. If the batteries are empty, the laser points will flash once before the measuring tool switches off. Always replace all the batteries at the same time. Only use batteries from the same man- ufacturer and which have the same capacity. u Take the batteries out of the measuring tool when you are not using it for a pro- longed period of time. The batteries can corrode and self-discharge during pro- longed storage in the measuring tool. Operation Starting Operation u Protect the measuring tool from moisture and direct sunlight. u 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 measur- ing 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", page25). The precision of the measuring tool may be compromised if exposed to extreme tem- peratures 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", page25). 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. Bosch Power Tools 1 609 92A 7S8 | (17.05.2022)24 | English Switching On/Off To switch on the measuring tool, slide the on/off switch (2) to the ON position. 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 (2) 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 45 °C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is opera- tional again and can be switched back on. Automatic shut-off The measuring tool automatically switches itself off after 60min of operation. If the switched on measuring tool is not within the self-levelling range (the laser points flash continuously), the automatic shut-off is reset to 60min. Automatic Levelling Position the measuring tool on a level, firm support or attach it to a tripod(11). To use the bottom laser point, rotate the measuring tool on the magnetic rotating mount(3) in such a manner that the laser point can be seen on the floor. After switching on, the automatic levelling function automatically compensates irregular- ities within the self-levelling range of ±4°. The levelling is finished as soon as the laser points light up continuously (i.e. no longer flashing) and do not move any more. If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than4° from the horizontal plane, the laser points will flash continuously and quickly. If this is the case, set up the measuring tool in a level position and wait for the self-level- ling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser points will light up continuously. In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again. After each levelling process, check the position of the hori- zontal and/or vertical laser points in relation to the reference points to avoid errors arising from a change in the measuring tool's position. 1 609 92A 7S8 | (17.05.2022) Bosch Power ToolsEnglish | 25 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 always mount the measuring tool on a tripod for measuring distances of 20m or more. In addition, pos- ition 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 be- fore beginning work. 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 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, flat surface. Switch on the measuring tool.

5 m – Aim the horizontal laser beam that runs parallel to the longitudinal axis of the measur- ing tool at the closer wall A and allow the measuring tool to level in. Mark the centre of the laser point on the wall (pointⅠ). Bosch Power Tools 1 609 92A 7S8 | (17.05.2022)26 | English 180°

– Turn the measuring tool 180°, allow it to level in and mark the centre point of the laser beam on the opposite wall B (pointⅡ). – Position the measuring tool –without rotating it– close to wallB, switch it on and al- low it to level in.

– Align the height of the measuring tool (using the tripod or by placing objects under- neath as required) so that the centre point of the laser beam exactly hits the previ- ously marked pointⅡ on wallB. 1 609 92A 7S8 | (17.05.2022) Bosch Power ToolsEnglish | 27

180° – Turn the measuring tool 180° without adjusting the height. Allow it to level in, then mark the centre point of the laser beam on wallA (pointⅢ). Ensure that pointⅢ is as vertical as possible above or below pointⅠ. – The discrepancy d between the two marked pointsⅠ and Ⅲ on wallA reveals the ac- tual height deviation of the measuring tool along the longitudinal axis. The maximum permitted deviation on the measuring distance of 2×5m=10m is as fol- lows: 10m×±0.35mm/m=±3.5mm. The discrepancy d between pointsⅠ and Ⅲ must there- fore amount to no more than 3.5mm. GPL5G: Repeat the measuring process for the two side laser beams that run along the transverse axis of the measuring tool. To do this, turn the measuring tool 90° clockwise or anticlockwise before beginning the measuring process. Checking Plumb Accuracy For this check, you will need a clear measuring space on firm ground with a distance of approx. 2.5m between the floor and the ceiling. – Place the measuring tool on the floor. Switch the measuring tool on and rotate it on the magnetic rotating mount(3) in such a manner that the bottom laser point can be seen on the floor. Allow the measuring tool to level in. Bosch Power Tools 1 609 92A 7S8 | (17.05.2022)28 | English 2,5 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).
