Basic Operation

How to use your Roteo

The wall mount and the metal head protection can both
be removed from the laser, if you wish to work without
these attachments.

Horizontal Setup

The laser can be mounted on a 5/8"-11 tripod or placed
directly on a solid, stable surface. Roteo 20/35 can be
suspended from a ceiling grid using the wall mount (see
later section).

Vertical Setup

The laser can be mounted on a 5/8"-11 tripod or placed
directly on its back (opposite the handle) on a solid,

3

Roteo 20HV/25H/35/35G - 1.2.0en

stable surface. For more stability, it is recommended to
use the wall mount. Use the support plate {D-7} for
stability when in vertical mode.

Turning on the laser

Turn on the laser with the On/Off key {B-3}. It does a
self-test and the beam blinks while the laser is self­leveling. After it is leveled, the head rotates. You can
choose H.I. Alert mode or change to manual mode (see
later sections).

The laser has a wide self-leveling range; however, if the
laser is set up out of the leveling range, the laser beam
will continue to blink and the rotation will not start.

X-axis and Y-axis LED indicators

The X and Y-axis LED indicators {B-10} slowly blink
green while the axes are leveling and turn on solid when
each axis has reached a level position. They will rapidly
blink red when in manual mode and the axis can be
adjusted. They will be red and on solid when in manual,
but the axis cannot be adjusted.

Button Functions

The CCW/CW and Plus/Minus buttons on the laser and
the remote control units have multiple functions
depending on the mode of operation. Please refer to the
chart below to better understand their functionality.

laser head will start rotating (Roteo 20HV/35/35G:
300 rpm, Roteo 25H: 600 rpm).

In manual mode, the laser does not self-level; this
means that the beam will rotate even if the laser is not
leveled. It can therefore be used on inclined planes such
as stairs, roofs, or when manual grade setting is
required. See later section on setting slope in manual or
semi-automatic modes.

H.I. Alert mode

The H.I. feature stops the laser automatically and
sounds an alarm if the laser is disturbed, preventing
inaccurate readings. It functions only when selected.

X To activate this safeguard feature, press the H.I. key

{B-4} after turning on the laser. The H.I. LED {B-12}
will blink rapidly while the laser is self-leveling.

X Thirty seconds after the head starts to rotate, the LED

will blink slowly, indicating the H.I. Alert function is
activated.

X If the laser is disturbed while in H.I. Alert mode, the

head will stop rotating, the beam will turn off, the LED
indicator will be on continuously, and an alarm will
sound (Roteo 35/35G).

X On Roteo 20HV and 25H models all LEDs will be on

continuously when disturbed in H.I. mode.

X Press the H.I. key to turn off the H.I. Alert function.

Check to see if the beam elevation has changed from
its original benchmark position.

X The laser is no longer in H.I. Alert mode. Press the H.I.

key to re-activate the H.I. Alert function.

Rotation mode (Roteo 20HV/35/35G)

The head rotates at four speeds: 0, 150, 300, 450, 600
rpm. The default setting is 300 rpm. The laser beam is
more visible at slower rotation speeds.

X To increase the rotation speed press the Plus key

{B-9}. Press the Minus key {B-8} to decrease speed.
Press and hold the Minus key to stop rotation.

X When the beam is stopped, the point can be moved to

the right or left using the Counter-clockwise / Clock­wise (CCW/CW) rotation keys {B-6 and B-7}. You can
also move the head manually to position the beam
point. To start rotation again, press the Plus key {B-9}.

Scanning mode (Roteo 20HV/35/35G)

For interior applications, scanning mode allows you to
see the beam easier at a distance.

X To scan press the Scan / Rotation key {B-2}. The

beam will blink until the laser has self-leveled.

X To increase the scan length press the Plus key {B-9}.

Press the Minus key {B-8} to decrease the scan
length.

X The scanning beam can be moved to the right or left

using the Counter-clockwise / Clockwise (CCW/CW)
rotation keys {B-6 and B-7}.

Motorized Wall Mount (Roteo 35/35G)

Activating the motorized wall mount

Allow the laser to self-level. Note the position or the
beam.

X Press the Motorized mount key {B-5} to activate the

mount. The motorized mount LED {B-11} will turn on
to indicate that the mount is now active (on the
Remote, press Scan/Rotation key {E-3, F-4} for 1.5
seconds).

X To raise the laser press the Plus key {B-9}. Press the

Minus key {B-8} to lower the laser.

Maximum movement

When the beam is at 0 on the adjustable plate, the laser
can be raised a maximum of 50 mm (2") and lowered a
maximum of 60 mm (2.25").

Wait until self-leveled

While the laser is moving on the mount it does not self­level and the beam continues to rotate.

X After moving the laser, wait a few seconds in case the

laser needs to self-level. Check that it is still on the
point or level desired and make adjustments if
needed.

Automatic exit from mode

If you have not activated the wall mount for five minutes,
the laser will automatically exit from the motorized mount
mode and return to the previous mode. The Motorized
mount LED will turn off.

Troubleshooting

X If the laser does not move on the mount, check that

the knobs {D-1} are tight enough to make the power
contact for the motor. The mount can also be
detached to check that the contacts are clean where
the laser and mount.

General

The following directions (in accordance with the state of
the art - international standard IEC 60825-1 (2007-03)
and IEC TR 60825-14 (2004-02)) provide instruction and
training information to the person responsible for the
product and the person who actually uses the equip­ment, to anticipate and avoid operational hazards.

The person responsible for the product must ensure that
all users understand these directions and adhere to
them.

Products classified as laser class 1, class 2 and class 3R
do not require

• laser safety officer involvement,

• protective clothes and eyewear,

• special warning signs in the laser working area
if used and operated as defined in this user manual due
to the low eye hazard level.

Products classified as laser class 2 or class 3R may
cause dazzle, flash blindness and afterimages, particu­larly under low ambient light conditions.

Roteo 20HV/25H/35/35G

The rotating laser produces a visible red/green laser
beam which emerges from the rotating head.

The laser product with a stationary rotating head is clas­sified as laser class 3R in accordance with *):

• IEC 60825-1 (2007-03): “Safety of laser products”.

)

Class 2 product if head is rotating.

*

Class 3R laser products:

Direct intrabeam viewing may be hazardous (low level
eye hazard), in particular for deliberate ocular exposure.
The risk of injury for laser class 3R products is limited
because of:

a) unintentional exposure would rarely reflect worst

case conditions of (e.g.) beam alignment with the
pupil, worst case accomodation.

b) inherent safety margin in the maximum permissible

exposure to laser radiation (MPE)

c) natural aversion behaviour for exposure to bright light

for the case of visible radiation.
