accidentally occurs, flush with water. If the liquid contacts the eyes, also seek medical attention.
Liquid leaking from the battery may cause irritation or burns.
▶ Use only batteries of the type approved for use with the applicable tool. Use of other batteries or
use of the batteries for purposes for which they are not intended presents a risk of fire and explosion.
▶ Store the battery in a cool and dry place. Never store the battery where it is exposed to direct sunlight or
sources of heat, e.g. on heaters / radiators or behind glass.
▶ When not in use, keep the battery and the charger away from paper clips, coins, keys, nails,
screws or other small metal objects that could cause a short circuit at the battery terminals or the
charging contacts. Short-circuiting the contacts on a battery or charger may cause burning injuries or
start a fire.
▶ Do not charge or continue to use damaged batteries (e.g. batteries with cracks, broken parts, bent
or pushed-in and/or pulled-out contacts).
▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for a certain
type of battery may present a risk of fire when used with other types of battery.
▶ Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
▶ The battery must be insulated or removed from the tool before the tool is shipped or sent by mail.
Leaking batteries may damage the tool.
▶ If the battery gets noticeably hot when not in use, this may indicate that the battery or the tool / battery
system is faulty. In this case, place the tool in a non-flammable location, well away from flammable
materials, where it can be kept under observation and allowed to cool down.

3.2 Intended use
The product described is a rotating laser with a visible rotating laser beam. It can be operated by one person.
The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles.
▶ Use only the Hilti B 12⁄2.6 Li-Ion battery for this product.
▶ Use only the Hilti C 4⁄1250 charger for this product.
3.3 Auto-leveling
Auto-leveling takes place after the tool is switched on. LEDs indicate the current operating status. Autoleveling is active and can be deactivated by way of the button. The tool can be set up directly on the
ground or floor, on a tripod, or with the aid of suitable mounting brackets.
3.4 Automatic alignment
Automatic alignment allows a single person to bring the laser plane into alignment with the laser receiver.
The rotating laser tool detects the applicable direction of alignment as follows:
• Horizontal in conjunction with the PRA 90 automatic tripod and PRA 30G laser receiver.
• Inclination in the X-axis in conjunction with the PRA 30G laser receiver.
• Vertical in conjunction with the PRA 30G laser receiver.
3.5 Inclination
Inclination can be carried out manually or automatically. The PRA 79 slope adapter can be used for larger
angles of inclination.
3.6 Surveillance function
The rotating laser monitors alignment of the laser plane in conjunction with the PRA 30G laser receiver. In
the event of an alignment deviation the system corrects the direction of the laser plane, keeping it at the
zero point of the laser receiver. The rotating laser corrects all errors caused by temperature fluctuations,
wind or other such influences. If the optical connection (line of sight) between the rotating laser and the laser
receiver is interrupted for longer than two minutes, the system indicates an error. During vertical alignment,
the surveillance function can be activated only via the AUTO menu.

3.7 Automatic switch-off
The tool switches off automatically if it is unable to level itself because the rotating laser:
• Is inclined too greatly relative to the horizontal plane (except when in inclined plane mode).
8 English
Printed: 07.05.2018 | Doc-Nr: PUB / 5376993 / 000 / 02
• Is blocked mechanically.
• Has been knocked off level by an impact or vibration.
• Has identified a fault.
When the tool has switched itself off, rotation stops and all LEDs flash.
3.8 Shock warning function
If the rotating laser is knocked off level during operation, the built-in shock warning function switches the
tool to warning mode. The shock warning function does not go active until two minutes after completion of
auto-leveling. If a button on the control panel is pressed within this two-minute period it will take a further
two minutes for the shock warning function to go active. If the rotating laser is in warning mode:
• All LEDs flash.
• The laser stops rotating.
• The laser beam switches off.
The sensitivity of the shock warning function can be set using the PRA 30G laser receiver.
The shock warning function can be switched off by pressing the button if the ground or floor is not free
from vibration or when you are working in inclined plane mode.

3.9 Sleep mode
Sleep mode may be activated on the rotating laser during breaks between work or during other activities. All
settings concerning the laser plane or inclination are retained while in this status. Sleep mode saves power
and extends battery life.
PRA 30G the laser receiver is used to activate / deactivate sleep mode.
Sleep mode remains active for a maximum of 4 hours. The system switches itself off after this time.
3.10 Switching off beam segments
Individual segments of the path of the laser beam can be deactivated in order to:
• Avoid exposing yourself or bystanders to the laser beam.
• Avoid influencing other measuring or alignment work being carried out in the vicinity.
3.11 Laser receiver / remote control unit
Hilti laser receivers digitally indicate the distance between the marking notch on the laser receiver and the
position at which the laser beam (laser plane) strikes the detection area on the receiver. The laser beam can
also be received over long distances. The PRA 30G can be used as a laser receiver and also as a remote
control unit for the rotating laser.
3.12 Pairing accessories and device
Pairing accessories and device
Pairing is the act of enabling accessories and devices to communicate with each other by wireless.
The rotating laser and the laser receiver are already paired when supplied. This helps ensure trouble-free
operation within the vicinity of other wireless devices.
Additional laser receivers or PRA 90 automatic tripods cannot be used without first being paired.
