Operation u Check the levelling and display accuracy of the meas- uring tool each time before beginning work and after longer transport of the measuring tool. u Protect the measuring tool from moisture and direct sunlight. u Do not expose the measuring tool to any extreme tem- peratures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measur- ing tool to adjust to the ambient temperature before put- ting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperat- ures or variations in temperature. u Avoid any impact to or dropping of the measuring tool. 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 Measur- ing Tool", page11). u Place the measuring tool in the provided case when transporting it over longer distances (e.g. in the car). Ensure that the measuring tool is correctly placed in the case. When placing in the case, the compensator is locked, as the measuring tool may otherwise be damaged by strong movements. Setting Up/Aligning the Measuring Tool Mounting on the Tripod Set up the tripod so that it is stable and secured against tip- ping over or slipping. Place the measuring tool onto the thread of the tripod via the tripod mount(13) and secure the measuring tool with the locking screw of the tripod. Align the tripod roughly. Over short distances, the measuring tool can be carried whilst mounted on the tripod. In order to avoid damage to the measuring tool, the tripod must be held vertically during transport and should not e.g. be carried lengthwise over the shoulder. Aligning the Measuring Tool Align the measuring tool using the levelling screws(12) so that the air bubble is positioned in the centre of the circular bubble vial(7).

Turn the first two levelling screws A and B to move the air bubble so that it is centred between the two levelling screws. Then turn the third levelling screw C until the air bubble is positioned in the centre of the circular bubble vial. Any remaining deviation of the measuring tool from the hori- zontal plane following the balancing of the circular bubble vial is compensated for by the compensator. While working, check regularly (e.g. by looking through the bubble vial mirror(3)) whether the air bubble is still in the centre of the circular bubble vial. Centring the Measuring Tool over a Ground Point If necessary, centre the measuring tool over a ground point. To do this, hang the plumb-bob(20) on the locking screw of the tripod. Align the measuring tool over the ground point either by moving the measuring tool on the tripod or by ad- justing the tripod. Focusing the Telescope Remove the protective cap from the lens(1). Point the telescope at a bright object or hold a white sheet of paper in front of the lens(1). Turn the eyepiece(6) until the crosshairs ap- pear sharp and deep black. Point the telescope at the levelling rod, using the rough sight(2) if necessary. Turn the focusing knob(16) until the graduation field of the levelling rod can be seen sharply. Align the crosshairs exactly with the centre of the levelling rod by turning the horizontal drive screw(14). When the telescope is correctly focused, the crosshairs and the image of the levelling rod must not move against each other when the eye is moved behind the eyepiece. Measuring Functions Always set up the levelling rod exactly vertically. Point the aligned and focused measuring tool at the levelling rod so that the crosshairs are on the centre of the levelling rod. 1 609 92A 8V7 | (05.07.2023) Bosch Power ToolsEnglish | 11 Reading Off the Height Read off the height on the levelling rod at the centre line of the crosshairs. Height measured in the figure: 1.195m. Measuring a Distance Centre the measuring tool over the point from which the distance is to be measured. Read off the height on the levelling rod at the top and bottom lines of the crosshairs. Multiply the difference between the two heights by 100 to get the distance from the measuring tool to the levelling rod. Distance measured in the figure: (1.347m–1.042m)x100=30.5m. Measuring Angles Centre the measuring tool over the point from which the angle is to be measured.

(9) (9) (10) (10) Point the measuring tool at point A. Rotate the horizontal circle(10) with the zero point toward the reference mark(9). Then point the measuring tool at point B. Read off the angle at the reference mark(9). GOL20D/GOL26D/GOL32D: Angle measured in the ex- ample: 45°. GOL20G/GOL26G/GOL32G: Angle measured in the ex- ample: 45gon. Accuracy Check of the Measuring Tool Check the levelling and display accuracy of the measuring tool each time before beginning work and after longer trans- port of the measuring tool. Checking the Circular Bubble Vial Align the measuring tool using the levelling screws(12) so that the air bubble is positioned in the centre of the circular bubble vial(7). Rotate the telescope by 180°. If the air bubble is no longer in the centre of the circular bubble vial(7), the circular bubble vial must be readjusted. Readjusting the Circular Bubble Vial Move the air bubble of the circular bubble vial(7) to a position midway between the end position of the check and the centre by turning the levelling screws(12). (17) (11) Using the hex key(17), turn the adjusting screws(11) until the air bubble is positioned in the centre of the circular bubble vial. Check the circular bubble vial by rotating the telescope by 180°. Repeat the adjustment procedure if necessary or con- tact Bosch customer service. Checking the Compensator After aligning and focusing the measuring tool, measure the height at a reference point. Then press and release the lock- ing button of the compensator(8). Measure the height at the reference point again. If the two heights do not match exactly, have the measuring tool repaired by Bosch customer service. Checking the Crosshairs A measuring distance of approx. 30m is required for the check. Set up the measuring tool in the centre and levelling rods A and B at both ends of the measuring distance. A B 30 m

= d After aligning and focusing the measuring tool, read off the heights at both levelling rods. Calculate the difference d between the height a

on levelling rod A and the height b

Set up the measuring tool approx. 1m away from levelling rod A. After aligning and focusing the measuring tool, read off the height a

at levelling rod A. Subtract the previously calculated value d from the meas- ured height a

in order to obtain the set value for the height

at levelling rod B. Measure the height b

at levelling rod B. If the measured value deviates by more than 6mm (GOL20D/G), 3mm (GOL26D/G) or 2mm (GOL32D/G) from the calculated set value, the crosshairs must be readjusted. Example:

–d=1.724m–0.248m=1.476m GOL20D/G: When measuring, the height b

must be 1.476m±6mm. GOL26D/G: When measuring, the height b

must be 1.476m±3mm. GOL32D/G: When measuring, the height b

must be 1.476m±2mm. Readjusting the Crosshairs (18) (5) Unscrew the eyepiece cover(4). Using the adjusting pin(18), turn the adjusting screw(5) clockwise or anticlock- wise, until the calculated set value for the height b

reached when measuring on levelling rod B. Screw the eyepiece cover(4) back on. Example: When measuring b
