Assembly

Inserting/Replacing the Battery

Alkali-manganese batteries are recommended for the meas-
uring tool.
To open the battery lid 9, slide the latch 8 in the direction of
the arrow and fold the battery lid up. Insert the batteries.
When inserting, pay attention to the correct polarity accord-
GCL 25
ing to the representation on the inside of the battery lid.

When the batteries are low, the battery low indicator 3 flashes
red. Additionally, the laser beams flash for approx. 5 s every
10 m
10 minutes. When the flashing initially begins, the measuring
30 m
tool can be operated for approx. 1 more hour. When the bat-
10 m
teries become empty, the laser beams flash one more time di-
5 m
rectly prior to the automatic shut-off.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
±0.3 mm/m
Remove the batteries from the measuring tool when
±0.5 mm/m
not using it for extended periods. When storing for ex-
±4°
tended periods, the batteries can corrode and discharge
themselves.

2 Protect the measuring tool against moisture and direct
sun light.
635 nm, <1 mW
Do not subject the measuring tool to extreme tempera-
1
tures or variations in temperature. As an example, do
1/4", 5/8"
not leave it in vehicles for long time. In case of large varia-
4 x 1.5 V LR06 (AA)
tions in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
Avoid heavy impact or falling of the measuring tool.
After heavy exterior impact on the measuring tool, an accu-
racy check should always be carried out before continuing
to work (see "Levelling Accuracy").
