13
1. Set the laser to an inclination of 0.000%.
2. Set up a leveling staff at a distance of 1m and a
second leveling staff at a distance of 60m. Note the
heights at which the laser beam strikes the staffs.
3. Set up an optical level in the middle between the
two leveling staffs and read the heights from both
staffs.
4. Calculate the difference in height indicated by the
optical level and the rotating laser on staffs 1 and
2. If both values are identical, then the laser tool is
correctly adjusted.
NOTE
If the differences X1 and X2 are not equal,
please contact your local Hilti Center or Hilti repres-
entative.
7.20 Working with the PPA 20 remote control unit

to select the laser beam mode remotely.
Press the applicable button on the remote control unit to
activate the corresponding function.
7.21 Working in standby mode
To switch the laser tool off, the ON / OFF button on the
laser tool must be pressed.
Only the laser beam is switched off by the ON / OFF
button on the remote control unit. The laser tool remains
in standby mode (the standby LED on the tool blinks
slowly).
When using the remote control unit, point the signal
transmission aperture on the remote control unit toward
the receiving window on the laser tool.
When switching the laser on, press and hold the ON /
OFF button for 2 seconds.
NOTE
If the pipe laser is moved, it can no longer be switched on
by the remote control unit. The message “Error” is shown
on the display of the pipe laser and the laser beam blinks
slowly.
Press the ON / OFF button on the pipe laser and check
that the laser is set up correctly.
8 Care and maintenance
8.1 Cleaning and drying
1. Blow dust off the lenses.
2. Do not touch the glass with your 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 (-30°C to +60°C).
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 40°C / F). Repack the equipment
only once it is completely dry.
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.
8.3 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.
8.4 Hilti calibration service
