2.2 Automatic / Manual modes
The A510S is in automatic self-leveling mode when turned on.
Once the instrument has self-leveled, the laser head will start rotating.
In manual mode (19), 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.
CAUTION: In manual mode, the beam rotates even if
the laser is not leveled.
2.3 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.
To activate this safeguard feature, press the H.I. key (18) after turn-
ing the laser on. The LED (21) will blink rapidly while the laser is
self-leveling.
About 30 seconds after the head starts to rotate, the LED will blink
slowly, indicating the H.I. Alert is activated.
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 continu-
ously, and an alarm will sound for 30 seconds.
Turn the laser off and turn it on again. Check to see if the beam ele-
vation has changed from its original benchmark position.
The laser is no longer in H.I. Alert mode. Press H.I. (18) to return to
H.I. Alert.
This feature is only available in automatic and semi-automatic
modes, and not in wall mount mode.
2.4 Rotation
The head rotates at 6 speeds: 0, 90, 150, 300, 450, and 600
8
rpm. 300 rpm is the default setting. The laser beam is more visible
at slower rotation speeds.
To increase rotation speed, press the + key (16) on the laser. Press
the – key (15) to decrease speed. Hold the – key to stop rotation.
When the beam is stopped, the point can be moved to the right or
left using the > or < keys (13 and 14). You can also move the
head manually to position the beam point. To start rotation again
press + key (16).
2.5 Using the laser chalk line
Ideal for short distance applications, the chalk line feature gives a
precise and stable laser line for working directly on your reference
plane.
To use the laser line, stop the rotation and flip up the collar located
on the side of the rotating head. This collar switches between point
and line modes.
You can move the stationary chalk line left by pressing key (13)
and right, by pressing key (14). You can also move the head manu-
ally or use the remote control.
If the laser is in chalk line mode, the detector will not
work. Switch to rotating point mode to detect the beam.
2.6 Scanning
For interior applications, scanning mode allows you to see the
beam easier at a distance.
If the laser is in chalk line, switch to beam point mode before scanning.
1. To scan, simultaneously press the – and < keys (15 and 13) on
the laser or press the scanning symbol on the remote control or the
detector.
2. The beam will blink until the laser has self-leveled.
3. To decrease the scan length, press the – key (15); to increase
the scan length, press the + key (16). Keys on the remote control or
detector can also be used for the scan functions.
4. To move the scan to the left, hold the < key. To move to the right,
use the > key (13 and 14).
5. To stop scanning, again press simultaneously on the – and < keys
(15 and 13).
