Bosch Power Tools

Direct the telescope towards the levelling rod, if required with 

help of the optical peep sight 

2

. Turn the focusing knob 

16

 un-

til the graduation field of the levelling rod appears sharp. Align 

the crosshair exactly with the centre of the levelling rod by 

turning the horizontal drive screw 

14

.

When the telescope is correctly focussed, the crosshair and 

the image of the levelling rod must remain aligned when mov-

ing your eye behind the eyepiece.

Measuring Functions

Always set up the levelling rod exactly vertical. Direct the 

aligned and focussed measuring tool against the levelling rod 

in such a manner that the crosshair faces centrally against the 

levelling rod.

Reading Off the Height

Read off the height of the levelling rod at the 

centre line of the crosshair.
Height measured in the figure: 1.195 m.

Measuring a Distance

Centre the measuring tool above the point 

from which on the distance is to be measured.
Read off the height of the levelling rod at the 

top and bottom stadia lines. Multiply the differ-

ence of both heights by 100 to receive the dis-

tance from the measuring tool to the levelling 

rod.
Distance measured in the figure: 

(1.347 m – 1.042 m) x 100 = 30.5 m.

Measuring Angles

Centre the measuring tool above the point from which on the 

angle is to be measured.

Direct the measuring tool against point 

A

. Rotate the horizon-

tal circle 

10

 with the zero point toward the reference mark 

9

. 

Then direct the measuring tool against point 

B

. Read off the 

angle at the reference mark 

9

.

GOL 20 D/GOL 26 D/GOL 32 D: Angle measured in the 

example: 45 ° .
GOL 20 G/GOL 26 G/GOL 32 G: Angle measured in the 

example: 45 gon.

Accuracy Check of the Measuring Tool

Check the levelling and indication accuracy of the measuring 

tool each time before using and after longer transport of the 

measuring tool.

Checking the Circular Bubble Vial

Align the measuring tool with 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 ° . When the air bubble is no long-

er in the centre of the circular bubble vial 

7

, the circular bub-

ble vial must be readjusted.

Readjusting the Circular Bubble Vial

Bring the air bubble of the circular bubble vial 

7

 in a position between the centre and the end 

position of the check by turning the levelling 

screws 

12

.

Using the Allen 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 ° . If required, repeat the procedure or refer to an author-

ised Bosch after-sales service.

Checking the Compensator

After aligning and focussing the measuring tool, measure the 

height at a reference point. Then press the lock button of the 

compensator 

8

 and release again. Measure the height again at 

the reference point.
If both heights do not exactly match, have the measuring tool 

repaired by an authorised Bosch after-sales service.

Checking the Crosshair

A measuring distance of approx. 30 m 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.
