Technical Data
Operation
f Check the levelling and indication accuracy
of the measuring tool each time before us-
ing and after longer transport of the meas-
uring tool.
f Protect the measuring tool against mois-
ture and direct sun light.
f Do not subject the measuring tool to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature
before putting it into operation. In case of ex-
treme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can
be impaired.

f Avoid any impact to or dropping of the
measuring tool. After severe exterior effects
to the measuring tool, it is recommended to
carry out an accuracy check (see “Accuracy
Check of the Measuring Tool”, page 13) each
time before continuing to work.
f Place the measuring tool in the provided
case when transporting it over larger dis-
tances (e.g. in the car). Ensure that the
measuring tool is correctly placed in the
transport case. When placing the measuring
tool in the case, the compensator is locked;
otherwise, it could be damaged in case of in-
tense movement.
Setting Up/Aligning the Measuring Tool
Mounting on the Tripod
Set up the tripod stable and safe against tipping
over or slipping off. Place the measuring tool via
the tripod mount 13 onto the male thread of the
tripod and screw the measuring tool tight with
the locking screw of the tripod.
Roughly level the tripod.
Over short distances, the measuring tool can be
carried mounted on the tripod. To ensure that
the measuring tool is not damaged during this,
the tripod must be held vertically during trans-
port, and should not be carried lengthwise over
the shoulder.
Aligning the Measuring Tool
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.
Turn the first two levelling screws A and B to
move the air bubble so that it is centred be-
tween the two levelling screws. Then turn the
third levelling screw C until the air bubble is po-
sitioned in the centre of the circular bubble vial.
Any remaining deviation of the measuring tool to
the horizontal plane following the balancing of
the circular bubble vial is compensated by
means of the compensator.
While working, regularly check (e.g. by viewing
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 Point on
the Ground
If required, centre the measuring tool over a
point on the ground. For this, hang the plumb-
bob 20 onto the locking screw of the tripod.
Align the measuring tool above the point on the
ground either by moving the measuring tool on
the tripod or by adjusting the tripod.
Focusing the Telescope
Remove the lens cap from the objective lens 1.
Direct the telescope against a bright
object or hold a white sheet of paper
in front of the objective lens 1. Turn
the eyepiece 6 until the crosshair ap-
pears sharp and deep black.
Direct the telescope towards the levelling rod, if
required with help of the optical peep sight 2.
Turn the focusing knob 16 until 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 moving 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 cross-
hair.
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 difference 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. Ro-
tate the horizontal circle 10 with the zero point
toward the reference mark 9. Then direct the
measuring tool against point B. Read off the an-
gle at the reference mark 9.
GOL 20 D/GOL 26 D: Angle measured in the ex-
ample: 45°.
GOL 20 G/GOL 26 G: Angle measured in the ex-
ample: 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 bub-
ble is no longer in the centre of the circular bub-
ble vial 7, the circular bubble vial must be re-
adjusted.
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 cen-
tre of the circular bubble vial.
Check the circular bubble vial by rotating the
telescope by 180°. If required, repeat the proce-
dure or refer to an authorised 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 re-
quired for the check. Set up the measuring tool
in the centre and levelling rods A and B at both
ends of the measuring distance.
After aligning and focussing the measuring tool,
read the heights at both levelling rods. Calculate
the difference d between the height a
1
of level-
ling rod A and the height b
1
of levelling rod B.
Example:
a
1
= 1.937 m
b
1
= 1.689 m
a
1
b
1
= 1.937 m – 1.689 m = 0.248 m = d
Set up the measuring tool approx. 1 m away
from levelling rod A. After aligning and focussing
the measuring tool, read the height a
2
at level-
ling rod A.
Subtract the previously calculated value d from
the measured height a
2
in order to receive the
set value for the height b
2
at levelling rod B.
Measure height b
2
at levelling rod B. When the
measured value deviates by more than 6 mm
(GOL 20 D/G) or 3 mm (GOL 26 D/G) from the
calculated set value, the crosshair must be read-
justed.
Example:
a
2
= 1.724 m
d = 0.248 m
a
2
d = 1.724 m – 0.248 m = 1.476 m
GOL 20 D/G: When measuring, height b
2
must
be 1.476 m ± 6mm.
GOL 26 D/G: When measuring, height b
2
must
be 1.476 m ± 3mm.
Readjusting the Crosshair
Unscrew the eyepiece cover 4. Using the adjust-
ing pin 18, turn adjusting screw 5 clockwise or
anticlockwise, until the calculated set value for
height b
2
is reached when measuring on level-
ling rod B.
Screw on eyepiece cover 4 again.
Example:
When measuring b
2
, the value 1.476 m must be
set.
Check the crosshair again. If required, repeat
the procedure or refer to an authorised Bosch
after-sales service.
