2 Description
2.1 Use of the product as directed
The Hilti PRI 2 is a laser tool with a rotating laser beam
and a reference beam set at 90° to the main beam.
The tool is intended mainly for indoor use. When used for
outdoor applications, care must be taken to ensure that
the general conditions are similar to those encountered
indoors.
The tool is designed to be used for determining, checking
/ transferring levels, verticals, alignment, plumb points,
slopes and right angles, for example:
Transferring datum lines and heights,
Marking out partition walls (vertical and/or at right angles)
Aligning systems and facilities in three axes.
Observe the information printed in the operating instruc-
tions concerning operation, care and maintenance.
The tool and its ancillary equipment may present hazards
when used incorrectly by untrained personnel or when
used not as directed.
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
The tool allows a single person to level or align in any
plane quickly and with great accuracy. Automatic leveling
(within ±5° inclination): The tool levels itself automatically
after switching on. LEDs indicate each operating status.
The tool can be set up directly on the floor, on a tripod,
or on the PRA 70/71 wall bracket.
2.3 Combination with the PRA 2 remote control
unit
The PRA 2 remote control unit can be used to control
the PRI 2 rotating laser conveniently from a distance.
The remote control function can also be used to adjust
alignment of the laser beam.
2.4 Combination with the PRA 22 laser receiver
The PRA 22 laser receiver facilitates indication of the
laser beam at great distances. For further information,
please refer to the PRA 22 operating instructions.
NOTE
Depending on the version purchased, the PRA 22 laser
receiver may not be included among the items supplied.
2.5 Speed of rotation
There are 5 different speeds of rotation (0, 90, 150, 300
or 600 revolutions per minute)
When rotation is switched off, the laser can be aligned
manually.
2.6 Horizontal plane (automatic leveling)
After switching on, the tool levels itself automatically in
all directions by way of 2 built-in servo motors.
2.7 Vertical plane (automatic leveling)
Vertical alignment is carried out automatically. The servo
buttons can be used to align (pivot) the vertical plane
manually.
2.8 Inclined planes
The inclination (slope) can be set manually in the hori-
zontal mode. This function is activated by pressing the
slope button. The servo buttons can be used to manually
incline the horizontal plane.
2.9 Automatic cut-out
When automatic leveling is activated for one or both
axes, the built-in servo system ensures that the specified
accuracy is maintained.
