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 tool with a visible green rotating laser beam and a reference beam
set at 90° to the main beam. The rotating laser can be used vertically, horizontally and for inclined planes.
The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles.
Examples of its uses are: transferring datum lines and height marks, determining right angles for walls,
vertical alignment on reference points and setting out slopes.

3.3 Features
The tool allows a single person to level or align in any plane quickly and with great accuracy.
4 speeds of rotation are available for use (0, 90, 300, 600 /min). The preset speed of rotation is 300 /min.
The tool is equipped with the following operating status indicators: auto-leveling LED, inclination angle LED
and shock warning LED.
When automatic leveling is activated for one or both axes, the built-in servo system ensures that the specified
accuracy is maintained. An automatic cut-out is activated when the tool is unable to level itself (i.e. when
the tool is outside its self-leveling range or movement is blocked mechanically) or the tool is knocked off
level (by vibration or an impact). When the tool has switched itself off, rotation stops and all LEDs blink.
Depending on the working distance and ambient light, visibility of the laser beam may be impaired. Visibility
of the laser beam can be improved through use of the target plate. In situations where laser beam visibility
is reduced, e.g. in bright sunlight, use of the laser receiver (accessory) is recommended.
Leveling
After switching on, the tool levels itself automatically within a range of ±5° by way of two built-in servo
motors. LEDs indicate the tool’s current operating status. The tool can be set up directly on the ground or
floor, on a tripod, or with the aid of suitable mounting brackets.
Vertical alignment is carried out automatically. The +/- buttons on the PRA 2 remote control unit can be
used to bring the vertical plane manually into alignment (pivot).
