Operating Instructions for General
Construction Applications
Note: A level plane of laser light is created by
the rotating beam of the laser. The laser light
can be used to reference elevations with the
use of a laser detector.
1. Place the instrument on a flat, level surface
such as a tripod. Setup the instrument in
an area where it can not be obstructed and
is set at a convenient height.
2. Press the
“2”
button. Allow the instrument
to self-level.
3. Set up a
“Benchmark”
(Fig. C)
4. Set the
Variable Rotation Mode
to the
desired rotation speed of the laser head.
Ideal speed for use with laser detector is
600 RPM. (RL25H: the rotation speed is
fixed at 600 RPM)
5. Take elevation readings using the plane
of laser light as a reference (Fig. E, C, F).
Follow the Detector Operation Procedures
in this manual.
Ceiling Grid Applications (RL25HV Only)
1. Attach the laser to the optional wallmount
bracket. Be sure the control buttons are
facing outward. Tightening the locking screw
will secure the instrument to the bracket.
2. After installing the first piece of ceiling
trim, attach the wallmount to it. Be sure the
wallmount is secure to the trim.
3. Press the “2” button. Allow the instrument
to self-level.
4. Adjust the distance of the instrument from
the grid, typically 1.5-inch (38mm) below
the grid. Loosen the adjustment screw
and slide the instrument up/down on the
wall mount. When the desired height has
been reached, tighten the adjustment screw
to secure the instrument.
5. Set up a “
Benchmark
”.
6. Install the ceiling grid. Attach the magnetic
laser target to the ceiling trim being
installed. Adjust the height of the trim until
the laser beam strikes the target (Fig. A).
Vertical Position (RL25HV Only)
1. Place the instrument in the vertical position
on a flat, level surface (Fig. B).
2. Press the “2” button. Allow the
instrument to self-level.
3. Set up a “Benchmark”
4. Adjust line position using the upper arrow
button “9” (CW) and lower arrow button “10”
(CCW)
OPERATIONS
Remove the laser from its carrying case.
Note: Instruments are shipped with ADS on
as the default setting. This setting can be
changed by the user (see Anti-Drift System -
ADS )
Leveling
1. The instrument can stand alone on a level,
sturdy surface or preferably secured to a
5⁄8-11 surveyor’s tripod.
2. Press the “2” button once, and allow time
(up to 65 seconds) for the instrument to self-
level.
Note: The laser head may begin to rotate before
leveling is complete. The self-leveling speed is
approximately 1° per 4 seconds.
3. After self-leveling, the instrument will begin
operating in Rotation Mode @ 600rpm.
Plumbing / Lay-Down
1. On a flat surface, place the instrument
on its back using the built-in trivet (control
panel facing upward).
2. Press the “2” button once, and allow time
for the instrument to self-level.
Variable Rotation Mode
The rotation mode will give you the option
of increasing or decreasing the speed of the
rotating laser. This feature can be used to
create a room-wide, 360° height reference or
vertical plumb line for general alignment, drop
ceiling installation, and more. Pressing the “4”
button, will adjust the speed from 600, 300, 150,
and 0 RPM.
Sweep or Scanning Mode
Instead of creating a room-wide reference line,
the Sweep (Scanning) Mode creates a shorter,
brighter laser “chalk line” that can be used for
leveling or plumbing doors, windows, fixtures,
and more. You may also use this feature to
keep the instrument from interfering with other
lasers and detectors on site. Pressing the “5”
button, will lengthen or shorten the sweep of the
laser beam. Preset angles of 10º, 25º , 50º can
be set. Position the sweep area by using the
upper arrow button “9” and lower arrow button
“10” .
