EGL624TM INTRODUCTION
Congratulations on purchasing the EGL624™ an electronic self levelling
contractors rotating lasers level built tough to handle the harshest of job
sites.
The EGL624™ is ideal for general site levelling, earth movers and
landscapers, simply set it up on a tripod, turn on, it electronically self levels
and the laser starts rotating. Then using the supplied LR715 receiver you
can set up your levels or grades.
The EGL624™ has manual dual grade setting capability and can be mounted
on its side for vertical alignment and site squaring.
The EGL624™ also can be used indoors both for horizontal levelling and
vertical alignment. Variable rotation speeds and scan modes increase
visibility indoors.
Other features of the EGL624™ include grade setting on the plumb dot
when mounted on its side, Vibration and Wind setting control, rechargeable
Ni-Mh and Std “C” Size battery operation and Five Year Redback Warranty.

EGL624TM OPERATING INSTRUCTIONS
Battery Instructions
To charge this battery pack simply inserting the charger plug into the charging
socket above the locking screw. The LED on the charger is illuminated red
during the charging process and will turn green once the batteries are
fully charged. Battery pack can be charged while inserted in the laser or
independently.
WhenthepowerLEDonthekeypadashes,therechargeablebatterypack
needs recharging or standard batteries need replacing. Note the charger will
only charge the supplied rechargeable battery pack.
Handy Hints
•
Prior to initial use, charge the rechargeable batteries for at least 8
hours.
•
Runningrechargeablebatteriescompletelyatwillincreasebatterylife.
•
The EGL624™ can operate off mains by plugging the charger (for
indoor use only) into the unit.
•
Remember the EGL624™ can operate using standard batteries when
rechargeable pack is out of charge.
The EGL624 has two battery options either 4 x standard “C” size Alkaline or
the Ni-Mh rechargeable pack. For standard 4 x “C” alkaline operation simply
insert into standard battery holder in the direction indicated and slide into
battery recess and tighten the locking screw.
To use the rechargeable
battery pack rst
remove standard pack
if inserted and place
into the same battery
recess and tighten
locking screw.

Turning Laser On
Press Power button on the keypad to turn on the EGL624™, power LED
willlight.BatteriesarelowifpowerLEDashes.Afterturningthelaseron,
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,awarningwillsoundandthelaserswillash.Re-setthelasermore
level if this occurs.
Tilt Mode
Tilt mode is somewhat similar to tilt on a pinball table in that if when running
theEGL624detectssignicantdisturbanceormovementthatcouldeffect
the accuracy of your work the laser will “Tilt” (stop working) and the laser
beamswillash to indicatethis.Youwillneedtothen relevelthe 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 .

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.
Usingtheremote,selectgrademodeontheXaxisandusetheSlopeGrade
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.
