Care And Maintenance - Hilti PR 2-HS Operating Instructions Manual

2. Press the on/off button.
The auto-leveling LED blinks green.
The laser switches on, the beam begins to rotate
and the "auto leveling" LED lights as soon as the
tool has leveled itself.
7.6 Working with slopes (manual settings)
NOTE
Check that the slope adapter is fitted correctly between
the tripod and the tool (please refer to the operating
instructions for the PRA 79).
7.6.1 Setting up
1. Set up the PRA 79 slope adapter in a suitable
position for the application, e.g. on a tripod.
2. Position the tripod either at the upper edge or lower
edge of the inclined plane.

8 Care and maintenance

8.1 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.
8.2 Care of the Li-ion battery
NOTE
A conditioning charge (as is required with NiCd or NiMH
batteries) is not necessary with Li-ion batteries
NOTE
Interruption of the charging procedure has no negative
effect on battery life.
NOTE
Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as with
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
3. Mount the rotating laser on the slope adapter and
bring it into alignment with the inclined plane, i.e.
parallel to the slope. The control panel of the PR 2-
HVS should face away from the direction of inclina-
tion.
4. Make sure that the slope adapter is in the zero
position (0°).
7.6.2 Switching on
1. Switch the tool on (see 7.2).
2. Press the "Inclined plane manual mode" button.
The "Inclined plane mode" LED then lights on the
control panel of the rotating laser.
The tool then begins automatic self-leveling. The
laser switches on and begins to rotate as soon as
this is complete.
3. Now set the slope adapter to the desired angle of
inclination.
4. To return to standard operating mode, switch the
tool off and then switch it back on again.
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 its performance be-
gins to drop significantly.
NOTE Recharging in good time will increase the
service life of the battery.
NOTE If use of the tool continues, further battery
discharge will be stopped automatically before the
battery cells suffer damage.
4. Charge the battery with the Hilti charger approved
for use with Li-ion batteries.
8.3 Storage
1. Remove the appliance from its case if it has be-
come wet. Dry and clean the tool, its transport
container and accessories (while observing the per-
missible temperature 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.
