Care And Maintenance; Troubleshooting - Hilti PMC 46 Operating Instructions Manual

7.3.6 Checking the vertical lines 16
1. Position the tool at a height of 2 meters.
2. Switch the tool on.
3. Position the first target plate T1 (vertical) at a
distance of 2.5 meters from the tool at the same
height (2 meters), so that the vertical laser beam
strikes the plate. Mark this position.
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.

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 neces-
sary, 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).

9. Troubleshooting

Fault
The tool can't be switched on.
6. Now place the tool on the floor on the mark for
position 2 which you have just made. Direct the
laser beam toward the target plates T1 and T2 so
that it strikes the plates close to their center lines.
7. 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
adjustment.
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 items only once they have dried completely and
then store them 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.
8.3 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
DANGER

tool.
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.
