Turning Laser On
Press Power button on the keypad to turn on the EGL624™, power LED
willlight.BatteriesarelowifpowerLEDashes.Afterturningthelaseron,
the laser will auto level and rotate. The power button on the remote will
not operate until the laser has been powered up from the keypad direct, the
power button on the remote then acts as a standby button. The EGL624TM
has a large self levelling range, if the laser happens to be set up outside this
range,awarningwillsoundandthelaserswillash.Re-setthelasermore
level if this occurs.
Tilt Mode
Tilt mode is somewhat similar to tilt on a pinball table in that if when running
theEGL624detectssignicantdisturbanceormovementthatcouldeffect
the accuracy of your work the laser will “Tilt” (stop working) and the laser
beamswillash to indicatethis.Youwillneedtothen relevelthe laser
by either pressing the level button on the remote or pressing the tilt
button twice on the keypad, wait a few seconds to level and then re-
check your work to maintain maximum accuracy.
Tilt mode is turned on and off with the tilt button on the keypad, the default
setting is off. Once the tilt button has been pressed the tilt LED will light
indicating it is on.
To deactivate the tilt mode press the tilt button the LED goes out. It
is recommended to use tilt mode when optimal accuracy is required or when
there is a chance that machinery or worker may interfere inadvertently with
the lasers level.
Rotation Speed Settings
• A short press of the Rotating Speed Button will switch the rotating
speed between 3 different rotational speeds, 800 rpm (default), 300
rpm and 5 rpm and rotating can also be stopped to create a dot.
Rotation speed will effect receiver performance at different distances.

EGL624TM OPERATING INSTRUCTIONS cont.
Setting Slope/Grades (refer to diagram page 4)
The EGL624TM can be used to set grades. In Slope (Grade) Mode you can set
a Grade in either the X or the Y Axis of up to 8% see the markings on top of
laser for axis alignment. With the EGL624 both “TILT” and “V-W-S” modes
can be used. The EGL624 is dual grade capable so a grade can be set on the
X and Y axis simultaneously, however, only when in manual mode page 10.
• Turn the laser on, allow to level and begin rotating.
• On either the key pad of the laser or on the remote control a short press
of the Slope (Grade)/Manual Mode button will activate slope mode
indicated by LED and the X LED will also illuminate. Note a long press
will enter Manual mode see page 10.
• Select the axis you wish to grade by again pressing this same button
and the selected X or Y axis LED will light. A long press when already
in slope mode will exit back to normal levelling.
• Move the laser plane on the selected axis up or down using the Slope
Grade Direction buttons . For dual grade use manual mode
see page 10.
• To reset and re-level press and hold the Slope Grade button .
www.redbacklasers.com.au

Setting a Grade
Following is a method of setting a grade using the slope (grade) buttons as
previously discussed. Here we will show setting a single grade on the X axis,
for a dual grade simple repeat the process on the Y axis (Manual Mode Only).
Set up the laser aligning the X axis with the direction of the required grade
rise/fall, the laser can be placed anywhere on site as long as the X axis runs
parallel with the desired grade.
For this example we want a grade of 1 in 60 or 1.667% or in other words for
every 6m (6000mm) travelled away from the laser along the X axis we want
the laser plain to tilt down/up 0.1m (100mm).
To achieve this measure out 6m away from the laser along the X axis and
hold the staff at this point slide the receiver up/down the staff until the
receiver indicates level (see receiver instructions page 10).
Then making a note of the height on the staff slide the receiver up/down the
staff 100mm, this is now the height the laser needs to be hitting to be setting
a 1 in 60 slope or grade.
Usingtheremote,selectgrademodeontheXaxisandusetheSlopeGrade
Direction buttons to slope the laser until the receiver shows level.
The Grade is now set at 1 in 60 or 1.667% on the X axis and anywhere
parallel to the X axis on site.
Chart below gives a range of grades and the distance the receiver shifts all
based a 5m distance of staff away from laser.
GRADIENT % DISTANCE LASER (M) MOVE RECEIVER (MM)
1 IN 20 5 5 250
1 IN 30 3.3 5 167
1 IN 40 2.5 5 125

EGL624TM OPERATING INSTRUCTIONS cont.
Manual Levelling Mode
V-W-S Vibration & Wind Sensor Setting
Manual mode can be used to simulate a manually levelling laser thus allowing
you to set the laser up at any angle and allow the laser to rotate. This can
be usefull for setting large manual grades on dam walls or indoor alignment
such as roof lines or balustrades.
In manual mode you can also set slopes (grades) on both axis at the same
time, however, “V-W-S” and “TILT” cannot be used and any disturbances of
the laser will not be indicated to the user.
• To enter manual mode press and hold Slope/Manual button note
short press will enter slope mode see page 8. Press and hold to exit.
• To set dual grade follow same instructions as pages 8/9, select axis and
slope beam, select second axis and slope that beam.
The EGL624 continuously self levels for utmost accuracy, in high winds or
vibrations the laser will stop rotating to re-level this may be inconvenient by
slowing down your work, however, by selecting V-W-S button the laser
continually re-levels but does not stop rotating whilst doing so.
An added feature in vertical rotation and using manual mode can be used to
slope the dot laser for setting manual pipe grades. Press the Slope/manual
button 3 times quicklt on the keypad (press hold on remote) manual
LED will light and use slope direction buttons on the remote to slope
up and down the dot.

www.redbacklasers.com.au
Vertical Rotation Operation (refer to diagram page 4)
The EGL624 can be used on its side for vertical alignment or together with
the dot laser out of the front to produce a 90 degree square for site layout.
The EGL624 can be placed on its side with the datum marker open or closed
and roughly levelled using the adjustment feet and bubble vial in the handle,
this brings the laser into self levelling range where the electronics take over.
Note in vertical rotation mode features such as “TILT”, “V-W-S” and “Scan”
can still be used the same as when in normal horizontal rotation mode.
When on its side press Slope button the “X” LED will light and the Slope/
Manual direction buttons on remote can be used to shift the dot/
rotating line to the left or right. This is ideal for site layout squaring;
• Place datum marker over the datum point marking the conjunction of
the 90 degree lines.
• Roughly align laser housing so dot is striking target point along the one
line of the 90 degrees, then use the direction buttons to electronically
netunethisalignment.
• Once the dot is on the target use the receiver to pick up the rotating line
on the second line of the 90 degree. Your square is now set.
Rotation Scan Modes - For Indoor Visibility
The Scan Mode stops the laser from rotating and toggles the beam left to
right, intensifying the beam making the laser more usable indoors as a visible
laser. You can set the scan angle to 180o, 90o, 45oand 10oand shift the beam
both left and right. The Scan Mode can be operated by both the Control key
pad on the laser and also the Remote Control.
• Press the Scan button to enter scan mode.
• The rst press, area scan 180 °, second press 90°, third press 45°,
fourthpress10°,fthpress180°etc….
• Rotate the scan line left or right by pressing Scan Shift buttons
as indicated by direction arrow on button.
• Press and hold Scan Shift button to rotate the scan line quickly.
• To return to rotation mode press the Rotate button .

Laser Receiver LR715 (refer to diagram page 5)
The LR715 is a heavy duty dual sided display rotating laser receiver, it can be
either hand held or with the staff bracket clamped onto a staff. The bubble
vials can be used to keep the receiver level.
The LR715 has two large LCD displays with progressive bars indicating when
the laser gets closer to the level mark. Move the receiver up and down (side
to side vertical rotation) slowly and watch the display change when the solid
tone is heard and the centre line is shown then the receiver is at the height
of the laser beam plane. The receiver will auto power down after 10 minutes
when not receiving laser pulses. Note receivers do not work in Scan mode.

Calibration & Self Check
AllRedbackLasershavebeencheckedforcalibrationandcertiedbyone
of our technicians here in Australia prior to despatch and should under
normal conditions not go out of calibration.  A calibration certied sticker
with the date and name of technician is located on the laser itself. It is
worth checking calibration from time to time particularly after any known
knocks or drops. An easy way to continually check calibration is to always
double check you work with the laser located in a different position or use
an alternate vertical line. Various other methods for checking calibration can
be found at www.redbacklasers.com.au/downloads or the laser can
be returned to our service department for checking and re-calibration. We
at Redback Lasers provide a once off free calibration and check within the
duration of the warranty period see page 16 for details.

EGL624TM TROUBLE SHOOTING
• Keep laser and accessories stored in protective case.
• Make sure laser is stored dry, dry out before storage to prevent damage.
• Remove batteries when not used for an extended period of time to prevent
leakage.
• The EGL624TM is a precision instrument and should not be subjected to excessive
knocks, drops or vibrations.
• Self check calibration from time to time. See page 14
• For service contact Redback Lasers. www.redbacklasers.com.au
Q. I cannot set grades on both axis simultaneously!
A. Check you are in manual mode, dual grades cannot be set in
slope mode.
Q. I have difculty using the remote control!
A. When you press a button each tone is equal to one press, so on
a toggle button like the power button if you press and hold and
hear 2 tones then it will have turned it on and then off again.
Q. The Laser does not power up!
A. Check the rechargeable batteries are charged and connected
correctly and or replace standard “C” size Alkaline batteries and
check they are inserted correctly.
Q. Using the receiver I get multiple heights showing as level!
A. This is a common problem with all laser levels and is usually due
 tothelaserbeingreectedoffawindoworotherreective 
 surface.Sotheoriginallaserbeamplusthereectionareboth
hitting the receiver at slightly different heights. To prevent this,
 setthelaserunitupsothatyoucannotseeareectivesurface
from where you are holding the receiver i.e. Any glass behind
receiver not the laser.
