Two models are described in this manual, the EAGL H and H+.
Some sections apply only to the EAGL H+. Although either pro-
duct is very simple to use, we recommend that you read this
manual before operating the laser.
1.1 Description
The EAGL H and H+ laser levels are automatically self-leveling
in horizontal. They have a visible laser beam for use indoors,
and can be used outdoors with the included detector. They also
have manual grade for slope matching.
The EAGL H+ has these additional features:
• Plumb beam
• Vertical mode, with semi-automatic leveling,
for squaring and short range vertical work
CAUTION
The EAGL H and H+ are Class 3R lasers, manufactu-
red to comply with the international rules of safety
IEC 60825-1, 2001. Although the power of the emis-
sion of the beam does not exceed 5 mW in Class 3R,
the following cautions are recommended:
• Do not stare directly at the beam
• Do not set up the laser at eye level

2.2 Vertical Setup (EAGL H+ only)
The EAGL H+ is equipped with semi-automatic leveling.
This means that you can put the EAGL H+ roughly in
vertical position but there is the need to level it accurately
with the use of the keypad on the laser or the LS50R
laser receiver / remote control.
2.2.1 How to use the semi-automatic leveling
Put the EAGL H+ in vertical position by using the
retractable feet on the laser or with use of a mount.
Find the leveling indication LEDs near the handle. You will
notice that at least one of the LEDs will start blinking.
If LED A is blinking
Press on the “UP” key on the EAGL H+ keypad (located
on the bottom of the laser keypad). If you use a LS50R
Receiver / Remote be sure not to have the receiver on and
press the “UP” symbol.
If LED C is blinking
Press on the “DOWN” key on the EAGL H+ keypad (located on
the bottom of the laser keypad). If you use a LS50R Receiver /
Remote be sure not to have the receiver on and press the
“DOWN” symbol.
If LED B is continuously on
The EAGL H+ is leveled correctly.
If LED B is continuously on but LED A or B is blinking
at the same time, the EAGL H+ is close to level.
Level the EAGL H+ correctly using the above
mentioned description.

2.3 H.I. Alert (Tilt) mode
The H.I. Alert feature stops the laser automatically if the laser is
disturbed, preventing inaccurate readings. It functions only
when selected.
To activate this safeguard feature, press the Tilt key (8) after tur-
ning the laser on. The LED next to it 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, and the LED indicator will
be on continuously.
Turn the laser off and turn it on again. Check to see if the beam
elevation has changed from its original benchmark position.
The laser is no longer in H.I. Alert mode. Press Tilt to return to
H.I. Alert.
CAUTION: The Tilt function is not available in vertical
mode on the EAGL H+.
2.4 Rotation speed
There are 3 rotation settings: 0, 90 and 600 rpm (the default
speed). To change to 90 rpm, press (11A). Press again to stop
rotation. The laser beam is more visible at the slower speed. It’s

also possible to stop the rotation and use the beam as a point
to view at a greater distance.
2.5 Matching slope (manual grade)
The laser can be used to match manual slope on both X and Y
axes. Two modes are available:
• Complete manual mode: X and Y axis will be both manual
• Semi-automatic mode: Y in automatic / X in manual
• Semi-automatic mode
1. Set the laser over a start point. Turn the laser so that
X on the top of the housing faces away from the
direction of the slope (and the laser keypad faces the
slope). Sight along the two alignment points on the
top cap to roughly align the X axis of the laser to the
second point.
2. After turning the laser on and allowing it to self-level,
hold the Auto/Man key for a few seconds until the LED
next to it is lit continually. The laser is in manual mode
in X axis and automatic self-leveling mode in Y axis.
3. Press ^ on the keypad to match a positive slope in X
and vto set a negative slope; the Y axis will stay level.
4. Press twice on the Auto/Man key to return to the
automatic mode.
• Manual Mode
1. Set the laser over a start point. Turn the laser so that
X on the top of the housing faces away from the
direction of the slope (and the laser keypad
faces the slope). Sight along the two alignment
points on the top cap to roughly align the X axis
of the laser to the second point.
2. After turning the laser on and allowing it to self-level,
press the Auto/Man key. The LED next to it will blink,
indicating you’re in manual mode and can match
slope in the X axis. The head will start rotating.
3. Press ^ on the keypad to match a positive slope in X
and vto set a negative slope.
4. To switch to the Y axis, press the Tilt key. Both X and
Y LEDs will blink, indicating you’re in manual mode
and can match slope in the Y axis.
Note: The Y axis grade will be at a 90 degree angle
from the X axis grade output.

• Universal SM200 mount: can be used as a wall mount, and with
the EAGL H+ for vertical setups on a tripod.
THIS CHAPTER IS VERY IMPORTANT:
Here are a few simple instructions to check your
laser for calibration. The laser is a precision instrument
and it is important that you keep it calibrated
and in proper condition. The accuracy of your work is
completely your responsibility and you should check
your instrument before beginning each job, and especially
after the instrument has taken a sharp jolt or
been dropped, or when temperature changes greater
than 50 degrees F (28 degrees C) have occurred.
6. Check and Adjust

13
The laser has 2 horizontal axes: X and Y, as indicated on the top of
the laser.
Each end of each axis must be checked for calibration. If needed,
the axis can be calibrated, carefully following the instructions. You
can also take the laser to a service center for calibration.
Check and calibrate in this order:
Check both sides of X axis.
• If X is within spec, proceed to check both sides of Y.
• If X needs calibration, calibrate X
Check both sides of Y axis.
• If Y is within spec, proceed to final X to Y check
• If Y needs calibration, calibrate Y; proceed to X to Y check
Final X to Y check: compare X, X’, Y, Y’
4.1 Calibration overview
Calibration is electronic, using the laser keypad. The optional
detector/remote control or optional small remote may also be used
(hold close to remote window below X LED).
If the beam is visible, calibrate using the non-rotating point. If it’s
too bright to see the beam, you’ll use the detector and will need to
have the beam rotating. When you’re in calibration mode, press
the rotation key (11A) on the laser to rotate the beam.
The axis LED should blink slowly when in calibration mode. When
laser is self-leveling or making an adjustment, it will blink rapidly.
IMPORTANT:
When pressing an arrow key to move the beam for
calibration, use short, rapid clicks. Do not hold the key
down. One click will move the beam a very small

amount (1/32" at 150' or 1mm at 100m). After pressing
the key, the LED will blink rapidly as the laser reacts.
Wait until the LED returns to a slow blink to proceed.
4.2 Horizontal checking and calibration
4.2.1 Checking X axis
1. Place the laser on a flat surface or tripod 100 ft. (30 m) away from
a wall. Position so that X (noted on top of laser) is facing the wall.
2. Turn on the laser.
3. Mark the location of the center of the beam. If it’s too bright to
see the beam, use the detector.
4. Rotate the laser 180 degrees so that X’ faces the wall.
5. Mark the location of the center of the beam near the first mark
so that both marks are in line, one above the other.
6. At 100 ft., the marks should be no more than 3/16” apart (at
30m, no more than 5mm apart). This is within the stated accuracy
of ± 3/32” at 100 ft. (± 0.0075%).
7. If the marks are close enough, X axis is within calibration. The
second axis Y must then be checked (see later section).
If the marks are not close enough, the X axis needs to be calibrated.
4.2.2 Calibrating X axis
The laser must be calibrated to bring the beam to the center of the
two X marks. Read "Calibration Overview" before proceeding.
1. Turn off the laser.
2. Hold the Auto/Man (6) key. While holding, momentarily press
the ON key.
3. After the LEDs blink in sequence, release the Auto/Man key.
4. X LED will blink rapidly, indicating leveling. When the LED
blinks slowly, the laser is ready to calibrate.
5. If you have not moved the laser, use the X marks made in
previous steps of “Checking X axis”.
6. Use arrows on the keypad to move beam up or down to the
halfway mark. If the X’ axis is toward the wall with the marks, use
the ^key (11B) to raise beam, and the vkey (11C) to lower beam.

15
7. After completing the X calibration, press the >>lkey (11D) to
change the axis and to calibrate the Y axis. On the remote, press
the double arrow key >>l.
8. If the Y axis doesn’t have to be calibrated, press the Auto/Man
key (6) to save the calibration you've just made on X axis. Or you
can save the calibration by pressing and holding for a few seconds
the rotation key (11A). On remote, use key with the small dot.
If you are not sure of the calibration, don’t save it and turn the
laser off using the On/Off key.
4.2.3 Checking Y axis
1. Rotate the laser 90 degrees so that Y is facing the wall.
2. Mark the location of the center of the beam.
3. Rotate the laser 180 degrees so that Y’ faces the wall.
4. Mark the location of the beam center near the first mark.
5. At 100 ft., the marks should be no more than 3/16” apart (at
30m, no more than 5mm apart). This is within the stated accuracy of
± 3/32” at 100 ft. (± 0.0075%).
6. If the marks are close enough, Y axis is within calibration.
Proceed to “Final X to Y Check.” If the marks are not close enough,
Y axis needs to be calibrated.
4.2.4 Calibrating Y axis
The laser must be calibrated to bring the beam to the center of the
two Y marks. Read "Calibration Overview" before proceeding.
If you are still in calibration mode from the X axis, turn Y’ towards
the wall and press the >>l key (11D) to change to the Y axis.
When the Y LED blinks slowly, it’s ready to be calibrated in Y axis.
If you’re no longer in calibration mode
1. Turn off the laser.
2. Hold the Auto/Man (6) key. While holding, momentarily press
the ON key.
3. After the LEDs blink in sequence, release the Auto/Man key.
4. Select the Y axis by pressing the >>lkey (11D) on the laser
keypad. On the remote, press the double arrow key >>l.

16
5. Y LED will blink rapidly, indicating leveling. When the LED blinks
slowly, the laser is ready to calibrate.
6. If you have not moved the laser, use the Y marks made in previous
steps of “Checking Y axis”.
7. Use keypad arrows to move beam up or down to the halfway mark.
If the Y’ axis is toward the wall with the marks, use the ^key (11B)
to raise beam, and the vkey (11C) to lower beam.
8. Press Auto/Man key (6) to save the calibration you've just made
on the Y axis. Or you can save the calibration by pressing and hold-
ing for a few seconds the rotation key (11A). On remote, use key with
the small dot.
If you are not sure of the calibration, don’t save it and turn the laser
off using the On/Off key.
Final X to Y Check
As a final check, compare X and Y axes to be sure that your
adjusted calibration is within the specs of +/- 3/32". The marks
for X, X’, Y, and Y’ should be no more than 3/16” apart at
100 ft. (5mm at 30m).
4.3 Cone error checking
1. Set up the laser 2 ft. or 1 meter from a wall (a) or a pole
and 100 ft. or 30 meters from another wall or pole (b).
2. Turn the laser on.
3. When the laser is leveled, stop the rotation and mark the
location of the beam (center of the beam) on the near wall (a),
using the detector if ambient conditions are too bright.
4. Rotate the laser 180° and mark the location of the center of
the beam on the far wall (b).
5. Install the laser 2 ft. or 1 meter from the far wall. When
the the laser has self-leveled, line up the beam near the
previous mark (b), and make a new mark (b').
6. Mark the location of the beam (a’) on the other wall near
the first mark (a).
7. Compare the two sets of marks on the walls. If the difference
between aa’-bb’ exceeds 3/16" (5mm), contact your local
service center.
