EL614TM 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.
When the power LED on the keypad ashes, the rechargeable battery pack
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.
• Running rechargeable batteries completely at will increase battery life.
• The EL614™ can operate o mains by plugging the charger (for indoor
use only) into the unit.
• Remember the EL614™ can operate using standard batteries when
rechargeable pack is out of charge.
The EL614 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 EL614™, power LED
will light. Batteries are low if power LED ashes. After turning the laser on,
the laser will auto level and rotate. The EL614TM 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 EL614 detects signicant disturbance or movement that could eect 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 pressing
the tilt button, note that the tilt is then disabled to re-enable press
the TILT button again so its LED light illuminates. After a few seconds the
laser will re-level, then re-check your work to maintain maximum accuracy.
Tilt mode is turned on and o with the tilt button on the keypad, the default
setting is o. 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 dierent rotational speeds. Sometimes dierent
rotation speeds will provide better reception with the LR715 receiver
when being used at dierent distances from the laser. For most
situations the default speed (800rpm) will provide best results.
V-W-S Vibration & Wind Sensor Setting
The EL614 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.

Setting Grades (requires remote control that comes with Grade & Grade +MM kits)
EL614TM OPERATING INSTRUCTIONS cont.
The EL614 Grade and Grade + MM kits come with a remote control that
can set a grade on one axis, it can be set to either the “X” or “Y” axis but
not both.
First 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 or in line 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 sta at this point slide the receiver up/down the sta until the
receiver indicates level.
Then making a note of the height on the sta slide the receiver up/down
the sta 100mm from the level point, 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 (see page
6 for remote diagram).
The Grade is now set at 1 in 60 or 1.667% on the X axis and anywhere on
or parallel to the X axis on site.

11
Laser Receiver LR715 (Standard & Grade Kits)
The LR715 is a heavy duty dual sided display rotating laser receiver, it can be
either hand held or with the sta bracket clamped onto a sta. The bubble
vials can be used to keep the receiver level.
• A press of the power button toggles the receiver on and o.
• The Speaker button toggles through 3 speaker volumes.
• Pressing the Coarse/Fine Mode button toggles through 3 levels
the rst being ne mode indicated by on the LCD the accuracy of
level is at its highest with 1mm tolerance movement by the receiver
before showing it o level. The next coarser mode allows 2mm
before showing o level the third press shows no symbol on the LCD
and allows 3mm before showing o level, these two coarser modes are
more suitable for general site levelling.
• The Back Light button toggles the LCD display back light.
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 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.
Indicates laser beam is below
line - slide receiver down.
Indicates laser beam is above
line - slide receiver up.
Indicates laser beam is on the
line.

and 65mm above or below the LCD display will indicate “OUT” and the
appropriate LED lights will ash. When a measurement is displayed it
indicates the distance between level and where the laser is actually striking
the receiver, the arrows and LED lights indicate which side of level the laser
is.

To select Accuracy press the Accuracy Options button which will cycle
through level bands of; 5mm, 9mm and 1mm (default). The default single
line between the two arrows on the display indicates ne mode 1mm,
3 lines 5mm and 5 lines is 9mm, the mm value ashes up on the LCD
display momentarily.
Units of measure can be selected with the “UNITS” button, millimetres is
default, you could also select cm, inch and feet.
The LCD backlight function is activated by the same button as Sound
Options to activate press and hold button for two seconds and back light
will turn on, to turn o press and hold same button for two seconds.
Low Battery is indicated by a battery symbol appearing on the bottom left
of the LCD display.
The “OSET” button is used to set a customised level point other than the
default level point as indicated by markings on the casing. A custom level
point can be set between 20mm above and 20mm below the default level
point. A custom level point is set to where the laser is currently striking
(assuming it is within the +/-20mm band) by pressing the “OSET” button
the receiver (while laser is striking it) will now show as being level at that
height the LCD display will ash “Oset” to indicate a custom level point
has been set. To clear this custom level and return to the default setting
either press the “OSET” button once more or power o the receiver.
Auto power o function will activate after 10 minutes of the receiver not
picking up a laser, this is to save battery.
The LR720 has bubble vials built into its casing, this is to aid in accuracy,
when the top bubble is central in the vial then the receiver housing is level
side to side. The bubble vial on the long edge is used when using the
receiver to pick up a rotating laser on the vertical plane for alignment.
The LR720 also features two magnets, useful for indoor installation work
when using steel structures. They are not designed for attaching to a
moving machine arm as heavy vibrations could make the receiver to fall.

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 dierent 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 o free calibration and check within the
duration of the warranty period see page 16 for details.

EL614TM 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. (battery leakage not covered by warranty)
• The EL614TM 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. 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 o a window or other reective
surface. So the original laser beam plus the reection are both
hitting the receiver at slightly dierent 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.
