6.9 Recalling the last previous value
If you switch the tool off to reposition it, the last previous inclination value saved in the receiver can be recalled.
1. Switch the tool on again
and activate inclined plane mode .
The first item in the menu is the last previous value.
2. Press
to select the value.
3. Check that the X and Y-values are, in fact, correct.
4. Confirm the values by pressing .
The rotating laser then resets itself to the previous inclination.
6.10 Resetting the X/Y value
17
Use the “Reset to 0” soft key to quickly reset the X and Y-values to 0.
6.11 Returning to standard mode
To return to standard operating mode, switch the tool off and then switch it back on again.
7 Care and maintenance
7.1 Cleaning and drying
1. Blow dust off exit windows.
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
Abrasive cleaning materials may scratch the
glass and impair the accuracy of the laser tool.
NOTE
Do not use any other liquids as these may
damage the plastic components.
4. Dry the equipment, observing the maximum tem-
peratures given in the technical data.
NOTE
Especially in summer and winter, take care
that the given maximum and minimum temperatures
are not exceeded, e.g. when the equipment is stored
in a motor vehicle.
7.2 Care of Li‑ion batteries
NOTE
With Li-ion batteries, a conditioning charge (as is required
with NiCd or NiMH batteries) is not necessary.
NOTE
Interruption of the charging procedure has no negative
effect on battery life.
NOTE
Charging can be started at any time with no negative ef-
fect on battery life. There is no memory effect (in contrast
to NiCd or NiMH batteries).
NOTE
For best results, batteries should be stored fully charged
in a cool, dry place. Storing the battery in places subject
to high ambient temperatures (e.g. at a window) has an
adverse effect on battery life and increases the rate of
self-discharge.
NOTE
Batteries lose capacity due to aging and overstressing.
They can then no longer be fully charged. You may
continue to work with a battery that shows signs of
aging, but the battery should be replaced in good time.
1. Avoid ingress of moisture.
2. Charge the battery fully before using it for the first
time.
3. Charge the battery as soon as performance drops
noticeably.
NOTE
Recharging in good time will increase the
service life of the battery.
NOTE
If use of the battery continues, further dis-
charge will be stopped automatically before the
battery cells suffer damage, i.e. the tool switches
itself off.
4. Charge the batteries using only the Hilti chargers
approved for use with Li-ion batteries.
7.3 Storage
1. Remove the tool from its case if it has become wet.
Dry and clean the tool, its transport container and
accessories (while observing the permissible tem-
perature range). Repack the equipment only once it
is completely dry.
2. Check the accuracy of the equipment before it is
used after a long period of storage or transportation.
3. Remove rechargeable and non-rechargeable batter-
ies from the tool or the laser receiver before storing
the units for long periods. The tool or laser re-
ceiver may suffer damage caused by leakage from
rechargeable or non-rechargeable batteries.
7.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the batteries before shipping the tool.
7.5 Hilti Measuring Systems Service
Hilti Measuring Systems Service checks the tool and, if
deviations from the specified accuracy are found, recali-
