4. Then place the second target plate T2 at a position 2
meters below the first target plate, so that the vertical
laser beam strikes the plate. Mark this position.
5. Mark position 2 at the opposite side of the test
setup (mirror image) on the laser line on the floor at
a distance of 5 meters from the tool.
6. Now place the tool on the floor on the mark for
position 2 which you have just made. Direct the
en
laser beam toward the target plates T1 and T2 so
that it strikes the plates close to their center lines.

8 Care and maintenance

8.1 Cleaning and drying

1. Blow dust off the glass.
2. Do not touch the glass with the fingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Do not use any other liquids as these may
damage the plastic components.
4. Observe the temperature limits when storing your
equipment. This is particularly important in winter
/ summer if the equipment is kept inside a motor
vehicle (-25°C to +63°C / -13°F to 145°F).
8.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at maximum 63°C / 145°F). Repack
the equipment only once it has dried completely and then
store it in a dry place.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
Remove the batteries from the tool before storing it for a
long period. Leaking batteries may damage the tool.

9 Troubleshooting

Fault
The tool can't be switched on.

function.

8.3 Transport

Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
DANGER
Always remove the batteries before shipping the tool.

8.4 Hilti calibration service

We recommend that the tool is checked by the Hilti cal-
ibration service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
Use can be made of the Hilti calibration service at any
time, but checking at least once a year is recommended.
The calibration service provides confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
The tool will be readjusted if deviations from the man-
ufacturer's specification are found. After checking and
adjustment, a calibration sticker applied to the tool and
a calibration certificate provide written verification that
the tool operates in accordance with the manufacturer's
specification.
Calibration certificates are always required by companies
certified according to ISO 900x.
Your local Hilti Center or representative will be pleased
to provide further information.
Possible cause
The battery is exhausted.
The battery is inserted the wrong way
round (incorrect polarity).
The battery compartment is not
closed.
The tool or selector switch is faulty.
The laser source or laser control unit
is faulty.
The laser source or laser control unit
is faulty.
The temperature is too high or too
low.
Read the distances D1 and D2 from each target
plate (distance of the laser line from the center of
the target plate) and calculate the difference (D = D1
- D2).
NOTE Take care to ensure that the target plates are
parallel to each other and that they are in the same
vertical plane. (Horizontal alignment may result in
measurement error).
If the difference D is greater than 3 mm, the tool must
be returned to a Hilti repair center for readjustment.
Remedy
Replace the battery.
Insert the battery correctly.
Close the battery compartment.
If necessary, have the power tool re-
paired by Hilti Service.
If necessary, have the power tool re-
paired by Hilti Service.
If necessary, have the power tool re-

Allow the tool to cool down or warm
up.
