2 Description

2.1 Use of the product as directed

The PR 2-HS is a rotating laser that projects a rotating, visible laser beam. The rotating laser can be used horizontally

and for inclined planes.

The tool is designed to be used for determining, transferring and checking references in the horizontal and inclined

planes. Examples of uses are the transferring of datum lines and heights. The tool is designed for professional use and

may be operated, serviced and maintained only by trained, authorized personnel. This personnel must be informed of

any special hazards that may be encountered.

The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used

not as directed.

Hilti supplies various accessories which allow the tool to be used with maximum efficiency.

Printed: 29.11.2013 | Doc-Nr: PUB / 5142564 / 000 / 02

To avoid the risk of injury, use only genuine Hilti accessories and insert tools.

Observe the information printed in the operating instructions concerning operation, care and maintenance.

Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or

explosion.

Modification of the tool is not permissible.

2.2 Features

Thetoolmakesitpossibleforasinglepersontoleveloraligninanyplanequickly and with great accuracy.

The tool levels itself automatically after switching on. The laser beam is switched on only when the specified accuracy

has been achieved.

LEDs indicate the current operating status.

The tool is powered by a rechargeable Li‑ion battery which can be charged while the tool is in operation.

2.3 Digital distance measurement display

The laser receiver displays digitally the distance between the laser plane and the marking notch on the laser receiver.

This allows the user to determine the exact position of the receiver relative to the laser plane, with millimeter accuracy,

inasingleoperation.

2.4 Horizontal plane

After switching on, the tool levels itself automatically by way of two built-in servo motors.

2.5 Inclined plane (manual alignment in the desired plane of inclination)

The desired inclination can be set with the aid of the PRA 79 slope adapter. For further information on using the slope

adapter, please refer to the instruction sheet supplied with the PRA 79.

2.6 Shock warning

The shock warning function is activated two minutes after the tool has leveled itself after switching on. If a button

is pressed within these two minutes, the two-minute delay begins again. The tool switches to warning mode if it is

brought out of level while in operation (due to vibration or an impact); all LEDs begin to blink and the laser switches

off (the head stops rotating).

2.7 Automatic cut-out

The laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range (±5°) or if movement

is blocked mechanically. The tool can be set up on a tripod with a 5/8" thread or stood directly on some other steady

surface (free of vibration). When automatic leveling is activated for one or both axes, the built-in servo system ensures

that the specified accuracy is maintained. The tool switches itself off when automatic leveling cannot be achieved (tool

set up outside its leveling range or physical impediment of the mechanism) or when knocked off level (see “Shock

warning” section).

NOTE

If the correct level cannot be achieved, the laser switches itself off and all LEDs blink.

2.9 Operating status indicators

The tool is equipped with the following operating status indicators: auto-leveling LED, battery charge status LED,

shock warning deactivation LED and inclined plane mode LED.

2.10 LED indicators

Auto-leveling LED The green LED blinks. The tool is in the leveling phase.

The green LED lights con-

stantly.

The tool has leveled itself / is operating

normally.

Shock warning deactivation LED The orange LED lights con-

stantly.

The shock warning function is deacti-

vated.

Inclined plane mode LED The orange LED lights con-

stantly.

Manual inclined plane mode is active.

All LEDs All LEDs blink. The tool has been bumped, knocked off

level or is exhibiting some error.

2.11 Charge status of the Li‑ion battery during operation

LEDs light constantly LEDs blink Charge status C

LED1,2,3,4 -C≧75%

LED1,2,3 -50 % ≦ C < 75 %

LED 1, 2 -25 % ≦ C < 50 %

LED 1 -10 % ≦ C < 25 %

-LED 1 C<10%

2.12 Charge status of the Li‑ion battery during charging while inserted in the tool

LEDs light constantly LEDs blink Charge status C

LED1,2,3,4 -C = 100%

LED1,2,3 LED4 75 % ≦ C < 100 %

LED 1, 2 LED 3 50 % ≦ C < 75 %

LED 1 LED 2 25 % ≦ C < 50 %

-LED 1 C<25%

2.13 Battery charging activity is shown on the battery display while charging the battery outside the tool.

If the red charging activity LED lights constantly, the battery is being charged.

If the red charging activity LED does not light, then either the charging operation is complete or the charger is providing

no current.
