EAGL H & H+

1
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

will start to rotate.
2.1 Horizontal Setup
1. The EAGL H can be used directly on the ground or
on a standard 5/8" - 11 tripod.
2. Press the On / Off key to switch the laser on. It
will start its automatic leveling.
3. To select H.I. Alert, press the Tilt key (8). The H.I.
Alert function will be active 30 seconds after the
laser has finished its self-leveling. See Section 2.3
for more information.
4. To turn the laser off, press On / Off key.

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.

5. Press ^ or v on the keypad to match slope in Y.
6. Press the Auto/Man key to return to automatic mode.
CAUTION: In manual mode, the beam rotates, even
if the laser is not leveled. The H.I. Alert (Tilt) function
is not available when the unit is in manual mode.
2.6 Power
2.6.1 Installing alkaline batteries
1. To install alkaline batteries in your EAGL H laser,
use a coin to unscrew the battery cap located near
the bottom of the instrument.
2. Remove the battery pack.
3. Insert two alkaline batteries (D or LR20). Orient them
per the battery outlines in the inside of the battery
pack (to match polarity).
4. Put the battery back into its place and tighten the
screw. Your EAGL H is ready for use.
To replace batteries
1. When battery power is low, the battery light
blinks but the laser still works. If the battery
continues to run down, the laser stops
completely.
2. Always replace both batteries at the same time.
2.6.2 Using rechargeable batteries
First-time use
If your EAGL H is equipped with an optional rechargeable
battery, you must charge it for 16 hours before first use.
1. Insert the charger plug into the jack located on the
battery pack.
2. Plug the charger into an electrical outlet (110 volts or
220 volts, depending on charger and country).
3. Charge for 16 hours.

Later recharges
The EAGL H can be charged while working. If electricity is
available on the job site, simply plug in the charger and keep
on working. You can also remove the battery pack to charge it,
and replace with the alkaline battery compartment to keep on
working.
For optimum life of the battery, it is recommended to charge the
battery after fully discharged. To assure battery life, do not
charge over 20 hours.
The battery and the charger can be damaged if damp.
Always store and charge your instrument in a dry and
covered place.
CAUTION: Use of controls or adjustments or perfor-
mance of procedures other than those specified
herein may result in hazardous radiation exposure.
1. The EAGL H is a precision instrument, which must
be handled with care. Avoid shock and vibrations.
Always store and transport the laser and
accessories in the carrying case.
2. Although weather resistant, you must always keep
your laser and its accessories dry and clean after
using. This will increase the battery life.
3. Do not store your laser at temperatures below
-4°F (-20°C) or above 176°F (80°C) because the
electronic components could be damaged.
4. Do not store your instrument in its case if the
instrument or the case is wet, to avoid water
condensation inside the instrument.
5. To maintain the precision of your laser, check and
adjust it regularly.
6. Keep the aperture lens clean. Use a soft cloth and
glass cleaner.
7. Please make sure to charge the batteries only when
they are out of power or becoming so.
Recharging batteries that are still useable will shorten
their capacity.
